FIX
4 cookies analyzed, 5 checks passed
Info::
Cookie 'MUID' has the Secure flag
Warning::
Cookie 'MUID' is missing the HttpOnly flag
Without HttpOnly, this cookie can be accessed by JavaScript, making it vulnerable to XSS-based theft.
Info::
Cookie 'MUID' has SameSite=None
Critical::
Cookie 'MUIDB' is missing the Secure flag
Without the Secure flag, this cookie can be sent over unencrypted HTTP, exposing it to interception.
Info::
Cookie 'MUIDB' has the HttpOnly flag
Warning::
Cookie 'MUIDB' has no SameSite attribute
Without an explicit SameSite attribute, browser default behavior varies. Set SameSite=Lax or Strict.
Critical::
Cookie '_EDGE_S' is missing the Secure flag
Without the Secure flag, this cookie can be sent over unencrypted HTTP, exposing it to interception.
Info::

Empty Page Detection
Action
1 empty-page signal(s) detected -- page may be a placeholder or have content-rendering bugs
FIX
1 empty-page signal(s) detected -- page may be a placeholder or have content-rendering bugs
Critical::
Page body has only 32 chars of text -- likely empty / placeholder
After HTML stripping, the page body contains 32 characters of text content. Below 200 chars almost always means: (1) the page is a placeholder that was never filled in, (2) JavaScript was supposed to render content but failed, (3) the page is a redirect / interstitial / wrapper that should have a real status code other than 200, or (4) it's a legitimately small page like a single-form login (in which case this finding is a false positive that confirms 'minimal content' is intentional). Review the page in a browser. If content is missing, the most common root cause is a JS-rendering pipeline that needs prerendering or server-side rendering for crawlers / scanners to capture content.
Got: 32 chars
F
Subresource Integrity Adoption
Action
0% SRI adoption (0/41 third-party resources)
FIX
0% SRI adoption (0/41 third-party resources)
Warning::
SRI adoption: 0/41 third-party resources protected (0%)
Of 41 third-party `<script>` / `<link rel=stylesheet>` resources, 0 (0%) declare a Subresource Integrity hash via the `integrity=` attribute. SRI binds the page to the exact bytes of the third-party resource: if the CDN is compromised, attacker-modified bytes won't match the declared hash and the browser refuses to execute the resource. Missing SRI on (first 5 examples): - https://r.bing.com/rs/2F/K/cc,nc/--1W9A1f5-07ByL9YFMiY5p9LQU.css?or=w - https://r.bing.com/rs/4r/gL/cc,nc/07goh3UcBfqcS932cBgUIxdsGJA.css?or=w - https://r.bing.com/rs/4r/go/cc,nc/X4V-IGCTgDxO69tbgGcZokQyezI.css?or=w - https://r.bing.com/rb/2B/cir3,cc,nc/t6ilQvdm1Kf1VaabvAwljycjim4.css?bu=CPUB-AGZAqsCnAKcApwC5AI&or=w - https://r.bing.com/rs/2B/5e/cir3,cc,nc/SU2qk8mq2PGo0FyvuJ0i_tgG07Y.css?or=w Fix: add `integrity="sha384-..."` and `crossorigin="anonymous"` attributes. Generators: srihash.org, or in-browser via `await crypto.subtle.digest('SHA-384', bytes)`. Cache-bust the resource URL when you change versions, since the integrity hash will mismatch with old cached bytes.
Got: 0% (0/41)

Permissions-Policy Granularity
Action
0% high-risk feature coverage (0/10)
FIX
0% high-risk feature coverage (0/10)
Warning::
Permissions-Policy covers 0/10 high-risk features (0%)
The Permissions-Policy header explicitly declares policies for 0/10 high-risk features. Covered: Not declared (default-allow): camera, microphone, geolocation, payment, usb, serial, midi, accelerometer, gyroscope, magnetometer The non-declared features fall back to their spec-default policy (usually `self`), which means an XSS-injected or compromised iframe could request them. For features the page genuinely doesn't use, declare `feature=()` to fully close them.

This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.

Expected: nosniff
Why this matters

MIME sniffing lets browsers run uploaded files as JavaScript, turning a file upload into an XSS.

Learn more ▾

Setting X-Content-Type-Options: nosniff tells browsers to trust your declared Content-Type instead of guessing. Without it, an attacker who uploads a polyglot file can sometimes get it executed as a script. One header, no downside.

Source: OWASP / MDN

This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN.

Expected: DENY
Why this matters

Without frame protection, your site can be embedded in a hostile page and used for clickjacking.

Learn more ▾

Clickjacking overlays your site under a transparent malicious page so users click invisible buttons. Setting X-Frame-Options: DENY (or a modern frame-ancestors CSP directive) blocks the embedding entirely. There's almost never a legitimate reason to allow it.

Source: OWASP / MDN

Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter.

Expected: strict-origin-when-cross-origin
Why this matters

Default browser behavior leaks full URLs (including query params and tokens) to every third-party resource — set a strict policy.

Learn more ▾

Without a Referrer-Policy header, browsers send the full referring URL with images, scripts, and fonts loaded from third-party origins. URLs containing tokens, user IDs, or session params end up in third-party logs. Set `Referrer-Policy: strict-origin-when-cross-origin` (or stricter) to limit leakage.

Source: MDN / W3C

COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.

Expected: same-origin
Why this matters

COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.

Learn more ▾

Cross-Origin-Opener-Policy: same-origin prevents cross-origin pages from sharing a browsing-context group with yours. This blocks cross-window references that enable Spectre-style timing attacks and tab-nabbing. Required if you want to enable SharedArrayBuffer.

Source: MDN / web.dev

COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.

Expected: require-corp
Why this matters

COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.

Learn more ▾

Cross-Origin-Embedder-Policy: require-corp ensures every embedded resource (script, iframe, image) explicitly allows being loaded cross-origin. Combined with COOP, this enables the cross-origin-isolated context that unlocks SharedArrayBuffer, high-resolution timers, and other powerful APIs.

Trusted Types (XSS Sink Hardening)
Trusted Types not enabled
REVIEW
Trusted Types not enabled
Info::
Trusted Types not enabled
Trusted Types (CSP3) is a Chrome 83+ defense that requires DOM-XSS sinks (innerHTML, document.write, eval, ...) to receive a typed-and-sanitized value rather than a raw string. Adding `Content-Security-Policy: require-trusted-types-for 'script'; trusted-types default` neutralizes most DOM-XSS even when a payload reaches a sink. Adoption is currently ~0.1% of pages so this is informational; a roll-out usually starts in report-only mode.

REVIEW
Referrer-Policy header not set -- browser default applies (modern: strict-origin-when-cross-origin; legacy browsers: no-referrer-when-downgrade)
Info::
Referrer-Policy header not set -- browser default applies
Without an explicit `Referrer-Policy` header, the browser falls back to its default policy. Modern browsers (Chrome 85+, Firefox 87+, Safari 15+) default to `strict-origin-when-cross-origin`, which is privacy-safe. Legacy browsers default to the leaky `no-referrer-when-downgrade`, which sends the full URL (including path + query) on cross-origin HTTPS-to-HTTPS requests. Set an explicit header to ensure consistent behavior: ``` Referrer-Policy: strict-origin-when-cross-origin ``` This matches the modern browser default and is privacy-safe without breaking referrer-based same-origin analytics.

2 risky subdomain name(s) advertised in certificate SANs
These names are publicly visible via Certificate Transparency logs (crt.sh, censys.io) -- any attacker can enumerate them in seconds. Operators are often unaware that internal/staging/admin endpoints are inadvertently advertised this way. Mitigation: use a wildcard cert that doesn't enumerate, issue per-environment certs without non-prod SANs on the prod cert, or move internal services to private DNS off the public cert.

MTA-STS policy file is reachable but no _mta-sts TXT record exists, so senders can't discover or version-pin the policy.

Learn more ▾

Senders look up the _mta-sts TXT record first to learn the current policy ID; without it they treat the policy as absent. Publish a TXT record at _mta-sts.<domain> with v=STSv1; id=<policy-version>.

DKIM signs outbound mail to prove origin. We probed common selectors (default, google, selector1, etc.) without finding a record. If you use a non-standard selector, this is a false negative.

Why this matters

No DKIM signature on outbound mail — receivers can't cryptographically prove the message came from your domain.

Learn more ▾

DKIM signs outbound mail with a private key whose public half lives in DNS at <selector>._domainkey.<domain>. Without DKIM, DMARC alone can't tell legitimate mail from spoofs, and large mailbox providers (Gmail, Yahoo) increasingly require DKIM for inbox placement. Note: this check probes a curated list of common selectors; non-standard selectors produce a false negative.

TLS-RPT (RFC 8460) lets MTAs report TLS-handshake failures, so you can detect and fix MTA-STS misconfigurations. Add a TXT record at _smtp._tls.<domain>.

Why this matters

Without TLS-RPT, you have no visibility into inbound TLS failures — MTA-STS misconfigurations stay hidden until users complain.

Learn more ▾

TLS-RPT (RFC 8460) is the feedback channel for MTA-STS: senders post aggregate reports of TLS-handshake failures to the URI in your _smtp._tls TXT record. Without it, an MTA-STS misconfiguration silently rejects mail and you find out only when someone notices missing email.

Source: RFC 8460

BIMI (Brand Indicators for Message Identification) lets supporting clients (Gmail, Apple Mail, Yahoo) display your verified logo next to your messages. Optional but raises trust signals. Requires DMARC at p=quarantine or p=reject to be honored.

Why this matters

Security gaps expose your site and users to attacks, eroding trust.

HTTP/2 provides multiplexing and header compression for better performance.

Why this matters

HTTP/1.1 forces the browser to make sequential requests, multiplying latency on every page.

Learn more ▾

HTTP/2 (and HTTP/3) multiplex many requests over a single connection, eliminating head-of-line blocking. HTTP/1.1 forces the browser to either queue requests or open many parallel connections — both worse. Most modern web servers support HTTP/2 with one config line.
