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.

For all sites VERY IMPORTANT medium EFFORT

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

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.

For important sites VERY IMPORTANT medium EFFORT

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

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

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

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

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

DNS Zone

The global DNS infrastructure is organized as a series of hierarchical DNS zones. The root zone hosts a number of global and country TLDs, which in turn host further zones that are delegated to their customers. Each organization that controls a zone can delegate parts of its namespace to other zones. In this test we perform detailed inspection of a DNS zone, but only if the host being tested matches the zone.

Test failed

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

Nameserver Names

Nameservers can be referred to by name and by address. In this section we show the names, which can appear in the NS records, the referrals from the parent zone, and the SOA record. In some situations, servers from the parent zone respond authoritatively, in which case we will include them in the list as well.

Nameserver Addresses

This section shows the configuration of all discovered nameservers by their IP address. To find all applicable nameservers, we inspect the parent zone nameservers for names and glue and then the tested zone nameservers for NS records. We then resolve all discovered names to IP addresses. Finally, we test each address individually.

Analysis

Inconsistent SOA records

DNS zone nameservers are not consistent because they're returning differing SOA records.

Inconsistent NS records

DNS zone nameservers are not consistent because they're returning differing NS records.

Nameserver provides a recursive service

Authoritative servers must not provide recursive services. This is necessary to minimize the chances of an attacker poisoning the nameserver's cache by sending queries that resolve to bogus information.

Nameserver addresses should have reverse names

According to RFC 1912, having reverse DNS configuration in place for every nameserver is a best practice that maximizes the chances of correct DNS operation. Further, some anti-spam techniques use reverse name resolution to allow traffic.

Nameserver A and AAAA records should have matching reverse records

According to RFC 1912, nameserver's PTR records must match their A and AAAA records to ensure maximum interoperability.

Improve IPv6 support

The Internet is in a slow transition to supporting IPv6 widely. Although at this time it is expected that most recursive DNS servers will use IPv4, adding support for IPv6 will enable transition to networks that use IPv6 exclusively.

DNS Records

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.

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.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

Useful DNSSEC Tools

Certification Authority Authorization

CAA (RFC 8659) 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.

Test passed

Everything seems to be well configured. Well done.

The iodef property specifies a means of reporting certificate issue requests or cases of certificate issue for the corresponding domain that violate the security policy of the issuer or the domain name holder.iodef	mailto:domains@microsoft.com flags: 0

Analysis

Issuance of S/MIME certificates not restricted

This policy doesn't restrict the issuance of S/MIME certificates. Consider using the `issuemail` directive to restrict which CAs, if any, can issue.

Issuance of BIMI not restricted

This policy doesn't restrict issuance of BIMI certificates. Consider using the `issuevmc` directive to restrict which CAs, if any, can issue.

CAA policy restricts issuance

Great. This domain name uses CAA to restrict which CAs are allowed to issue certificates for it.

Policy uses reporting

Good. This policy uses reporting, which means that your contact information is available should someone need to contact you about a CAA violation. Do note that you're not guaranteed to be notified, given that CAs generally don't support notifications yet.

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.

Test passed

Analysis

Email servers match MTA-STS policy

Good. This host supports MTA-STS, which means that it restricts which MX servers can be used and how they are configured. We've verified that all MX servers listed here match the policy.

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

TLS 1.2 supported

Good. This server supports TLS 1.2, which can provide strong security when configured correctly. This version of the TLS protocol is necessary to provide good security with a wide range of clients that don't yet support TLS 1.3.

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.

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.

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.

Analysis

Certificate chain is correct

Good. This chain contains all the right certificates and in the right order.

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 applicable, not implemented, or disabled

Your server doesn't support this feature.

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.

Test passed

Everything seems to be well configured. Well done.

SPF policy is valid

Good. Your SPF policy is syntactically valid.

Policy DNS lookups under limit

Good. Your policy stays under the limit of up to 10 DNS queries. The SPF specification Section 4.6.4. requires implementations to limit the total number of DNS queries. Policies that exceed the limit should not be used and may not work in practice.

Lookups: 6

DMARC

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a scalable mechanism by which a mail-originating organization can express domain-level policies and preferences for message validation, disposition, and reporting, that a mail-receiving organization can use to improve mail handling.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

DMARC Policy Information

The location from which we obtained this policy.Policy location	_dmarc.outlook.com
DMARC version used by this policy.v	DMARC1
Indicates the policy to be enacted by the receiver at the request of the domain owner. Possible values are: none, quarantine, and reject.p	none
Requested mail receiver policy for all subdomains. Same format as for the p tag.sp	quarantine
Percentage of messages from mail stream to which the DMARC policy is to be applied.pct	100
Addresses to which aggregate feedback is to be sent.rua	mailto:rua@dmarc.microsoft
Addresses to which message-specific failure information is to be reported.ruf	mailto:ruf@dmarc.microsoft
Configures failure reporting.fo	1

Analysis

DMARC policy found

Policy: v=DMARC1; p=none; sp=quarantine; pct=100; rua=mailto:rua@dmarc.microsoft; ruf=mailto:ruf@dmarc.microsoft; fo=1

Host: _dmarc.outlook.com

Valid external destination

Permission record location: outlook.com._report._dmarc.dmarc.microsoft

External destination: mailto:rua@dmarc.microsoft

Permission record contents: v=DMARC1

Policy is valid

Good. You have a valid DMARC policy.

Activate DMARC policy

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.

Test passed

Everything seems to be well configured. Well done.

MTA-STS Policy Indicator

Location from which we retrieved the policy indicator.Location	_mta-sts.outlook.com

Policy mode, which can be one of 'none', 'testing' and 'enforcing'. Guess which is best! :)mode	enforce
One 'mx' directive specifies one email server pattern that's allowed for this host.mx	*.olc.protection.outlook.com

Analysis

MTA-STS policy is valid

Good. Your MTA-STS policy is valid.

Policy host certificate is valid

Good. Your MTA-STS policy is delivered via a web server that has a valid publicly trusted certificate. This is a necessary condition for the policy to be recognized.

Analysis

Certificate chain is correct

Good. This chain contains all the right certificates and in the right order.

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.

Test passed

Everything seems to be well configured. Well done.

TLS-RPT Policy

Location from which we retrieved the policy indicator.Location	_smtp._tls.outlook.com
TLS-RPT standard version used by this policy indicator.Version	TLSRPTv1
Reporting endpoints specified in the policy.Reporting Endpoints	https://tlsrpt.azurewebsites.net/report

Analysis

SMTP TLS-RPT policy valid

Good. Your TLS-RPT policy is valid. SMTP TLS Reporting is a young standard that is not yet widely supported, but support is probably going to increase over time.

HTTP (80)

To observe your HTTP implementation, we submit a request to the homepage of your site on port 80, follow all redirections (even when they take us to other domain names), and record the returned HTTP headers.

Test passed

Everything seems to be well configured. Well done.

Information leakage in HTTP response header

A HTTP response provided by this server includes a server that reveals potentially sensitive information about the software running on it. There is no reason why this information should be provided to the public and we recommend that it is removed.

Header value: ASP.NET

Header name: X-Powered-By

HTTP redirects to HTTPS

Good. This plaintext HTTP server redirects to HTTPS.

Analysis

Information leakage in HTTP response header

Header value: ASP.NET

Header name: X-Powered-By

HTTP redirects to HTTPS

Good. This plaintext HTTP server redirects to HTTPS.

HTTP (443)

To observe your HTTPS implementation, we submit a request to the homepage of your site on port 443, follow all redirections (even when they take us to other domain names), and record the returned HTTP headers. We use the most recent set of headers returned from the tested hostname for further tests such as HSTS and HPKP.

Test passed

Everything seems to be well configured. Well done.

Analysis

TLS 1.3 not supported

TLS 1.3 is the latest revision of the TLS protocol and a significant improvement over earlier versions. Developed over a period of several years and extensively analyzed prior to the release, TLS 1.3 removed insecure features, and improved both security and performance. This version of TLS should be the main protocol used with modern clients.

TLS 1.2 supported

Deprecated protocols not supported

Excellent. This server doesn't support any of the deprecated protocol (TLS 1.1 and earlier).

Strong key exchange detected

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.

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 setting enables negotiation of best security.

All TLS connections with this server satisfy Apple's CT requirements

All TLS connections established with this server satisfy Chrome's CT requirements, using certificate, TLS extension, or OCSP response as SCT transport method.

SCT transports: CERT

All TLS connections with this server satisfy Chrome's CT requirements

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.

Platform	Trusted
Apple
Google AOSP
Microsoft
Mozilla

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.

Analysis

Certificate chain is correct

Good. This chain contains all the right certificates and in the right order.

DANE (443)

Feature not applicable, 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 passed

Everything seems to be well configured. Well done.

HTML 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.

Encryption of Embedded Resources

In this section we look at the transport 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

0 CSS file(s)
0 out of 0 are secure

0 media file(s)
0 out of 0 are secure

Encryption of 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.

0 link(s)
0 out of 0 are encrypted

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

Everything seems to be well configured. Well done.

HSTS Policy Main host

URL from which this policy was obtained.Location	https://www.outlook.com/
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	31,536,000 seconds (about 1 year)
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

Policy is valid

OK. Your HSTS policy uses correct syntax.

Long policy age

Your HSTS policy has a long max-age value, which offers better protection.

Policy covers subdomains

When subdomains are included, network attackers are unable to manufacture arbitrary subdomains to manipulate cookies and trick users.

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.

Policy preloaded

Excellent. This host is covered by a preloaded HSTS policy.

Preloaded host: outlook.com; includeSubDomains=true

HSTS Policy Apex host

URL from which this policy was obtained.Location	https://outlook.com/
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	31,536,000 seconds (about 1 year)
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

Policy is valid

OK. Your HSTS policy uses correct syntax.

Long policy age

Your HSTS policy has a long max-age value, which offers better protection.

Policy covers subdomains

When subdomains are included, network attackers are unable to manufacture arbitrary subdomains to manipulate cookies and trick users.

Preload intent declared

Good. With the preload directive set, browsers have a green light to embed the HSTS policy.

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.

Policy preloaded

Excellent. This host is covered by a preloaded HSTS policy.

Preloaded host: outlook.com; includeSubDomains=true

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 applicable, 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 applicable, 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.

Test passed

Everything seems to be well configured. Well done.

No external scripts
SRI not needed

No external stylesheets
SRI not needed

Analysis

No remote resources

The homepage of this site doesn't contain any remote resources so SRI is not needed.

Expect CT

Expect-CT is a deprecated response HTTP header designed to enable web sites to monitor problems related to their Certificate Transparency (CT) compliance. Should any CT issues arise, browsers that supported this header will submit reports to the specified reporting endpoint. Chrome was the browser that introduced support for this response header, but later deprecated it and removed it in version 107.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

Analysis

Deploy Expect-CT to enable reporting

An Expect-CT policy enables web sites to monitor for any problems related to their Expect-CT compliance, detecting potentially serious issues quickly. When issues arise, compliant browsers will submit reports to the specified reporting endpoints. Before CT became required for all public certificates the Expect-CT was also used to require CT, but that use case no longer applies.

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 applicable, not implemented, or disabled

Your server doesn't support this feature.

XSS Protection

Some browsers ship with so-called XSS Auditors, built-in defenses against XSS. Although these defenses work against simple reflective XSS attacks, they can be abused by skillful attackers to add weaknesses to otherwise secure web sites. These dangers are present in both filtering and blocking modes. At this time, the Safari browser ships with its XSS defenses enabled by default. For this reason, the best approach is to explicitly disable this functionality.

Feature not applicable, not implemented, or disabled

Your server doesn't support this feature.

Analysis

Explicitly disable browser XSS protection

For best security, every web site should explicitly disable browser-based XSS protection. This is because this type of functionality can be used to introduce vulnerabilities into otherwise error-free web sites.

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.
