Web Security Overview
Error
HTTPS

Web sites need to use encryption to help their visitors know they're in the right place, as well as provide confidentiality and content integrity. Sites that don't support HTTPS may expose sensitive data and have their pages modified and subverted.
There are issues with this site's HTTPS configuration.

For all sites VERY IMPORTANT medium EFFORT
Supported and well configured
HTTPS Redirection

To deploy HTTPS properly, web sites must redirect all unsafe (plaintext) traffic to the encrypted variant. This approach ensures that no sensitive data is exposed and that further security technologies can be activated.

For all sites VERY IMPORTANT low EFFORT
Warning
HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) is an HTTPS extension that instructs browsers to remember sites that use encryption and enforce strict security requirements. Without HSTS, active network attacks are easy to carry out.
There are issues with this site's HSTS configuration.

For important sites VERY IMPORTANT medium EFFORT
Not supported
HSTS Preloaded

HSTS Preloading is informing browsers in advance about a site's use of HSTS, which means that strict security can be enforced even on the first visit. This approach provides best HTTPS security available today.

For important sites VERY IMPORTANT medium EFFORT
Not supported
Content Security Policy

Content Security Policy (CSP) is an additional security layer that enables web sites to control browser behavior, creating a safety net that can counter attacks such as cross-site scripting.

For important sites IMPORTANT high EFFORT
Email Security Overview
Supported and well configured
STARTTLS

All hosts that receive email need encryption to ensure confidentiality of email messages. Email servers thus need to support STARTTLS, as well as provide decent TLS configuration and correct certificates.

For all sites VERY IMPORTANT low EFFORT
Supported and well configured
SPF

Sender Policy Framework (SPF) enables organizations to designate servers that are allowed to send email messages on their behalf. With SPF in place, spam is easier to identify.

For important sites IMPORTANT low EFFORT
Not supported
DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a mechanism that allows organizations to specify how unauthenticated email (identified using SPF and DKIM) should be handled.

For important sites IMPORTANT low EFFORT

Name Server Configuration

Correctly functioning name servers are necessary to hold and distribute information that's necessary for your domain name to operate correctly. Examples include converting names to IP addresses, determining where email should go, and so on. More recently, the DNS is being used to communicate email and other security policies.

Test passed
Everything seems to be well configured. Well done.

DNSSEC

DNSSEC is an extension of the DNS protocol that provides cryptographic assurance of the authenticity and integrity of responses; it's intended as a defense against network attackers who are able to manipulate DNS to redirect their victims to servers of their choice. DNSSEC is controversial, with the industry split largely between those who think it's essential and those who believe that it's problematic and unnecessary.

Test passed
Everything seems to be well configured. Well done.

DNSSEC is well configured
Good. This domain name has well-configured DNSSEC.

Useful DNSSEC Tools

Certification Authority Authorization

CAA (RFC 6844) is a new standard that allows domain name owners to restrict which CAs are allowed to issue certificates for their domains. This can help to reduce the chance of misissuance, either accidentally or maliciously. In September 2017, CAA became mandatory for CAs to implement.

Feature not implemented or disabled
Your server doesn't support this feature.

Analysis

Powerup!
There is no CAA policy on this hostname
CAA policies can be used to restrict which CAs are allowed to issue certificates for a hostname. As such, CAA can be used to enforce an organization-wide policy and to prevent issuance of unauthorized certificates. The CA/Browser forum requires CAs to consult CAA configuration during certificate issuance from September 2017.

Email (SMTP)

An internet hostname can be served by zero or more mail servers, as specified by MX (mail exchange) DNS resource records. Each server can further resolve to multiple IP addresses, for example to handle IPv4 and IPv6 clients. Thus, in practice, hosts that wish to receive email reliably are supported by many endpoint.

Analysis

Notice
Some SMTP server assessments have been retrieved from cache
Some SMTP server assessment results have been retrieved from our cache. Because many hosts point to the same SMTP servers, we use a short-term cache to avoid testing the same SMTP servers over and over again.

Latest cache timestamp: 17 Oct 2019 17:26 UTC

Earliest cache timestamp: 13 Oct 2019 16:48 UTC

Notice
Some SMTP server assessments contain partial information
Comprehensive TLS assessments require many connections, which is exactly what many SMTP servers don't like. We implement a two-tier assessment approach. To give you some results as fast as possible, we perform shallow assessments that use only one connection per SMTP server. We then have a background process that performs complete assessments slowly, trying to accommodate each server individually. The results presented here contain partial information. If you come back later we may be able to provide complete assessment resuls.

Email TLS (SMTP)

Transport Layer Security (TLS) is the most widely used encryption protocol on the Internet. In combination with valid certificates, servers can establish trusted communication channels even with users who have never visited them before. Network attackers can't uncover what is being communicated, even when they can see all the traffic.

Analysis

Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Notice
Partial results shown
SMTP assessments usually take a long time. To get you some results faster, we initially perform shallow checks. If you come back later we may be able to show you complete results.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Analysis

Notice
Deprecated TLS 1.0 protocol supported
TLS 1.0 is a weak older protocol that should be phased out. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make decisions with confidence.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Analysis

Notice
Deprecated TLS 1.0 protocol supported
TLS 1.0 is a weak older protocol that should be phased out. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make decisions with confidence.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Analysis

Notice
Deprecated TLS 1.0 protocol supported
TLS 1.0 is a weak older protocol that should be phased out. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make decisions with confidence.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Analysis

Notice
Deprecated TLS 1.0 protocol supported
TLS 1.0 is a weak older protocol that should be phased out. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make decisions with confidence.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Notice
Relaxed TLS assessment criteria applied to SMTP on port 25
We apply relaxed assessment criteria when evaluating TLS configuration of SMTP servers on port 25. This is because most delivery agents fall back to delivering via plaintext on failure to negotiate encryption. Some configuration elements that can be abused to attack other ports and protocols (e.g., SSLv2 and export cipher suites) are penalized in the same way as for other protocols. We will review this policy in the future.

Email Certificates (SMTP)

A certificate is a digital document that contains a public key, some information about the entity associated with it, and a digital signature from the certificate issuer. It’s a mechanism that enables us to exchange, store, and use public keys. Being able to reliably verify the identity of a remote server is crucial in order to achieve secure encrypted communication.

Test passed
Everything seems to be well configured. Well done.

Email DANE (SMTP)

DNS-based Authentication of Named Entities (DANE) is a bridge between DNSSEC and TLS. In one possible scenario, DANE can be used for public key pinning, building on an existing publicly-trusted certificate. In another approach, it can be used to completely bypass the CA ecosystem and establish trust using DNSSEC alone.

Feature not implemented or disabled

SPF

Sender Policy Framework (SPF) is a protocol that allows domain name owners to control which internet hosts are allowed to send email on their behalf. This simple mechanism can be used to reduce the effect of email spoofing and cut down on spam.

Although syntactically valid, your DMARC policy is effectively disabled. An effective policy must set the value of the 'p' directive to either 'quarantine' or 'reject'. In addition, if the 'pct' directive is present, it must be set to a value other than zero. (The default is 100, which means to apply policy to all emails.)

MTA Strict Transport Security

SMTP Mail Transfer Agent Strict Transport Security (MTA-STS) is a mechanism enabling mail service providers to declare their ability to receive Transport Layer Security (TLS) secure SMTP connections, and to specify whether sending SMTP servers should refuse to deliver to MX hosts that do not offer TLS with a trusted server certificate.

Feature not implemented or disabled
Your server doesn't support this feature.

SMTP TLS Reporting

SMTP TLS Reporting (RFC 8460), or TLS-RPT for short, describes a reporting mechanism and format by which systems sending email can share statistics and specific information about potential failures with recipient domains. Recipient domains can then use this information to both detect potential attacks and diagnose unintentional misconfigurations. TLS-RPT can be used with DANE or MTA-STS.

Feature not implemented or disabled
Your server doesn't support this feature.

WWW TLS

Transport Layer Security (TLS) is the most widely used encryption protocol on the Internet. In combination with valid certificates, servers can establish trusted communication channels even with users who have never visited them before. Network attackers can't uncover what is being communicated, even when they can see all the traffic.

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good

Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.
Good
TLS 1.2 supported
Good. This server supports TLS 1.2, which is currently the dominant protocol version. It provides strong and modern encryption facilities and doesn't have serious weaknesses.
Good
Strong key exchange detected
Excellent. All cipher suites on this server rely on strong key exchange. The sweet spot is 2048 bits for DHE and 256 bits for ECDHE. Putting ECDHE suites first guarantees best security and best performance.
Good
Server prefers forward secrecy and authenticated encryption suites
Excellent. Not only does this server enforce its server preference, but it also has at the top of the list suites that support both forward secrecy and authenticated encryption. This is the best TLS 1.2 can offer.
Good
Server enforces cipher suite preferences
Excellent. This server enforces server cipher suite preference, which means that it is able to select the best suite from the options submitted by clients. Combined with a well designed list of supported cipher suites, this settings enables negotiation of best security.

Analysis

Notice
Deprecated protocols supported
TLS 1.0 and TLS 1.1 are deprecated protocols that should be disabled if possible. TLS 1.0, in particular, is a weak older protocol that has many weaknesses. Sites that aim at a wide audience might still need to support TLS 1.0 for the time being, because many older clients don't support newer protocol versions. Sites with a modern user base might be able to disable TLS 1.0 even now. We recommend that you enable logging of encryption parameters, after which you can examine your protocol usage and make a decision with confidence. As of July 2018, PCI DSS doesn't allow use of TLS 1.0. Exceptions apply in some cases.

WWW Certificates

A certificate is a digital document that contains a public key, some information about the entity associated with it, and a digital signature from the certificate issuer. It’s a mechanism that enables us to exchange, store, and use public keys. Being able to reliably verify the identity of a remote server is crucial in order to achieve secure encrypted communication.

Certificate Trust

Determining whether a certificate is considered valid is a complicated process that depends on the exact configuration of the validating party. For trust to be established, the certificate must form a chain that ends with a trusted root. In this section we evaluate the server's certificate against major root stores.

Certificate Chain

For a server certificate to be valid, it must be presented as part of a complete and valid certificate chain. The last certificate in the chain should be the root and is usually not included in the configuration.

DANE (443)

DNS-based Authentication of Named Entities (DANE) is a bridge between DNSSEC and TLS. In one possible scenario, DANE can be used for public key pinning, building on an existing publicly-trusted certificate. In another approach, it can be used to completely bypass the CA ecosystem and establish trust using DNSSEC alone.

Feature not implemented or disabled
Your server doesn't support this feature.

Cookies

Cookies are small chunks of text that are sent between your browser and a website. They are often essential to the operation of the site and sometimes contain sensitive information. Session cookies sent from secure sites must be explicitly marked as secure to prevent being obtained by active network attackers.

Test failed
We've detected serious problems that require your immediate attention.

HTTP Cookie: _wp_session  Session cookie

Cookie value. As far as the cookie RFC is concerned, the value
is an opaque string which only the application should interpret.

Cookie domain. When domain is implied (not explicitly set in a cookie),
most browsers (but not IE) treat the cookie as host-only, meaning that
no other server can overwrite it.

Cookie path. This field can't be used as security measure,
but it could be of use to avoid cookie name collision

Path

Cookies are designed to always expire. Session cookies
are truly ephemeral and remain cached until the browser
is closed. The Expires and Max-Age cookie attributes can
be used to specify that a cookie should stay alive for
longer.
Expires
Thu Oct 17 21:14:41 UTC 2019 (29 minutes)
The HttpOnly flag prevents the cookie from being accessed
from JavaScript, thus making them more difficult
to obtain after a successful XSS attack.
HttpOnly
The Secure flag signals to browsers that the cookie
should be transmitted only over an encrypted channel.
Secure
Normally, when a browser makes a request to a web site,
it sends all associated cookies. This is not always
desirable, because it might allow third-party sites
to perform site actions under the identity of the user.
This attack is known as Cross-Site Request Forgery.
With SameSite cookies (still in development, but already
supported in some browsers), you can choose to be more
strict. The possible values are 'lax' and 'strict'.
SameSite

Analysis

Error
Session cookie is not secure
This cookie, which has been sent over an encrypted channel, doesn't have the secure flag set. As a result, an active network attacker can easily recover it and hijack the user session.
Powerup!
Session cookie is not HttpOnly
This session cookie is not marked as HttpOnly. Session cookies usually don't need to be accessed from JavaScript. When marked as HttpOnly, they can't be accessed from JavaScript, making it more difficult for an attacker to obtain them after a successful XSS attack.
Powerup!
SameSite attribute not used
An upcoming standard, SameSite cookies, creates more secure cookies that are sent only on requests that originate from the same site that issued them. They are designed to prevent Cross-Site Request Forgery (CSRF) or at least make it more difficult.
Powerup!
Name prefix not used
Cookie name prefixes are a recent improvement that enable web application developers to opt-in into a more secure type of cookies. Virtually all cookies would benefit from using either the '__Secure-' or the '__Host-' prefix. The former ensures that a plaintext cookie can't overwrite a secure cookie. The latter ensures that the cookie is sent back only to the host that issued it.

Mixed Content

On virtually all web sites, HTML markup, images, style sheets, JavaScript, and other page resources arrive not only over multiple connections but possibly from multiple servers and sites spread across the entire Internet. For a page to be properly encrypted, it’s necessary that all the content is retrieved over HTTPS. In practice, that’s very often not the case, leading to mixed content security problems.

Test passed
Everything seems to be well configured. Well done.

Embedded Resources

In this section we look at the security of all embedded resources. Mixed active content occurs when there are unprotected scripts or styles embedded in a page. This is typically not allowed by modern browsers. Mixed passive content (images, videos and such) are typically allowed, but shouldn't be present.

0 script(s)
  0 out of 0 are secure
1 CSS file(s)
  1 out of 1 are secure  View all
1 media file(s)
  1 out of 1 are secure  View all

Outbound Links

Ideally, an encrypted page should only have links that lead to other encrypted pages. If plaintext links are used, passive network attackers can see where people go after they visit your web site. It's also possible that some sensitive information is leaked in the Referer header.

25 link(s)
  25 out of 25 are encrypted  View all

HTTP Strict Transport Security

HTTP Strict Transport Security (HSTS) vastly improves security of the network encryption layer. With HSTS enabled, browsers no longer allow clicking through certificate warnings errors, which are typically trivial to exploit. Additionally, they will no longer submit insecure (plaintext) requests to the site in question, even if asked.

Test passed, but there are warnings
Some aspect of your site's configuration require your attention.

HSTS Policy  Main host

URL from which this policy was obtained.Location https://www.revittemplate.com.br/
Specifies policy duration. Once activated, HSTS stays in force
until this time lapses. Browsers update policy cache duration
every time they receive a new HSTS header from a site.
max‑age
2,592,000 seconds (about 30 days)
When present, this directive forces HSTS activation
on allsubdomains. For best security, HSTS should be
deployed on the bare domain name (e.g., example.com)
and all its subdomains.
includeSubDomains
Presence of this directive indicates that a web site wishes to
permanently use HSTS and that its policy information should be
preloaded (embedded in browsers).
preload

Analysis

Good
Policy is valid
OK. Your HSTS policy uses correct syntax.
Powerup!
Insufficient policy age
The max-age of your HSTS policy is a little low, consider increasing it to at least 10,886,400 seconds (about 4 months), which is the minimum requirement for preloading.
Warning
No subdomains
This HSTS policy doesn't cover subdomains, which is a requirement for preloading. Additionally, without full coverage, HSTS can't protect from certain cookie attacks that typically allow active network attackers to inject cookies into an application.
Good
Redirection from HTTP to HTTPS to the same host
Good. The redirection from HTTP to HTTPS is to the same host. This approach ensures that HSTS is activated on the hostname when it's accessed via plaintext.
Powerup!
No parent protection
This host could benefit from further protection if the apex hostname would be configured with a HSTS policy that uses 'includeSubDomains'. Enabling HSTS on an entire domain name is the only approach that provides robust security.

OK. Your HSTS policy uses correct syntax.
Powerup!
Insufficient policy age
The max-age of your HSTS policy is a little low, consider increasing it to at least 10,886,400 seconds (about 4 months), which is the minimum requirement for preloading.
Warning
No subdomains
This HSTS policy doesn't cover subdomains, which is a requirement for preloading. Additionally, without full coverage, HSTS can't protect from certain cookie attacks that typically allow active network attackers to inject cookies into an application.
Good
Preload intent declared
Good. With the preload directive set, browsers have a green light to embed the HSTS policy.
Good
Redirection from HTTP to HTTPS to the same host
Good. The redirection from HTTP to HTTPS is to the same host. This approach ensures that HSTS is activated on the hostname when it's accessed via plaintext.
Warning
Policy not preloaded
When hostname is preloaded, that means that browsers embed your HSTS policy and apply it even to the first request sent to your web site. This server indicates preloading in its policy, but the domain name isn't actually preloaded. We classify this as a warning because it's a common problem to place the 'preload' keyword in the policy even though the infrastructure is not ready for preloading. This is dangerous because, in this situation, anyone can submit this domain name for preloading just by visiting hstspreload.org. We recommend that you either preload this domain name yourself—if it's ready— or remove the preloading indicator from the policy until it is ready.
Warning
Preload policy doesn't satisfy preload requirements
This HSTS policy specifies the preload directive but doesn't satisfy one or more preload conditions.

HTTP Public Key Pinning

HTTP Public Key Pinning (HPKP) enables site operators to restrict which certificates are considered valid for their domain names. With a valid HPKP configuration, sites can defeat man in the middle (MITM) attacks using fraudulent or misissued certificates. HPKP is an advanced feature, suitable for use by only high-profile web sites.

Feature not implemented or disabled
Your server doesn't support this feature.

Content Security Policy

Content Security Policy (CSP) is a security mechanism that allows web sites control how browsers process their pages. In essence, sites can restrict what types of resources are loaded and from where. CSP policies can be used to defend against cross-site scripting, prevent mixed content issues, as well as report violations for investigation.

Feature not implemented or disabled
Your server doesn't support this feature.

Subresource Integrity

Subresource Integrity (SRI) is a new standard that enables browsers to verify the integrity of embedded page resources (e.g., scripts and stylesheets) when they are loaded from third-party web sites. With SRI deployed, remote resources can be used safely, without fear of them being modified by malicious parties.

SRI required
This page contains remote resources that are under the control of third parties. Deploy SRI to protect them from modification.

Expect CT

Expect-CT is a response HTTP header that web sites can use to monitor problems related to their Certificate Transparency (CT) compliance. Additionally, they can also instruct browsers to reject any certificates in their name that are are not CT-compliant.

Test passed
Everything seems to be well configured. Well done.

Expect-CT Policy

URL from which this policy was obtained.Location https://www.revittemplate.com.br/
Specifies policy duration. Once activated, Expect-CT stays in force
until this time lapses. Browsers update policy cache duration
every time they receive a new Expect-CT header from a site.
max‑age
604,800 seconds (about 7 days)
This optional directive controls whether CT compliance
will be enforced by your policy. It's useful if you're
confident in your configuration and wish to deploy CT
before browsers start enforcing it.
enforce
This optional directive enables reporting and specifies
the endpoint clients should use to submit reports.

Excellent. This web site has a valid Expect-CT policy.

Frame Options

The X-Frame-Options header controls page framing, which occurs when a page is incorporated into some other page, possibly on a different site. If framing is allowed, attackers can employ clever tricks to make victims perform arbitrary actions on your site; they do this by showing their web site while forwarding the victim's clicks to yours.

Feature not implemented or disabled
Your server doesn't support this feature.

XSS Protection

Modern browsers ship with built-in defenses against Cross-Site Scripting (XSS), usually known as XSS Auditors. Web sites are allowed to control the defenses if they specify an X-XSS-Protection header in their HTTP responses. Recommended policies are either to block XSS attacks, or disable the defenses if you think false positives are possible. Filtering, where offending fragments of data are removed, is not recommended because it can be abused by attackers to selectively deactivate script files.

Feature not implemented or disabled
Your server doesn't support this feature.

Content Type Options

Some browsers use a technique called content sniffing to override response MIME types provided by HTTP servers and interpret responses as something else (usually HTML). This behavior, which could potentially lead to security issues, should be disabled by attaching an X-Content-Type-Options header to all responses.

Test passed
Everything seems to be well configured. Well done.
