Permissions-Policy Granularity

Action

30% high-risk feature coverage (3/10)

FIX

30% high-risk feature coverage (3/10)

Permissions-Policy covers 3/10 high-risk features (30%)

The Permissions-Policy header explicitly declares policies for 3/10 high-risk features. Covered: camera, microphone, geolocation Not declared (default-allow): 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.

Got: 30% (3/10)

D

Referrer-Policy Strictness

Action

Referrer-Policy is `origin-when-cross-origin` (leaky -- origin sent cross-origin even on protocol downgrade)

FIX

Referrer-Policy is `origin-when-cross-origin` (leaky -- origin sent cross-origin even on protocol downgrade)

Referrer-Policy: `origin-when-cross-origin` -- leaky -- origin sent cross-origin even on protocol downgrade

Same-origin requests get full URL; cross-origin gets only origin. Similar shape to the modern default BUT does NOT suppress Referer on HTTPS-to-HTTP downgrade -- the origin leaks even when the protocol is downgrading to HTTP. Switch to `strict-origin-when-cross-origin` for the same UX with no downgrade leak.

Got: origin-when-cross-origin

B

WAF / Bot Protection

No WAF detected via response headers

REVIEW

No WAF detected via response headers

No WAF detected

Response headers don't match any known WAF or bot-management product. Sites exposed to abuse (login, signup, payment) typically benefit from a WAF such as Cloudflare, Akamai, AWS WAF, or Imperva.

B

CSP Inline-Style Readiness

1 inline style attribute(s) detected

REVIEW

1 inline style attribute(s) detected

Each `style=""` attribute forces `style-src 'unsafe-inline'` in any Content-Security-Policy, which negates most of CSP's XSS-mitigation value. 1 inline style(s) is low. Affected element types include: span. Move styles to a stylesheet; use CSS custom properties for runtime-dynamic values; or adopt a nonce/hash CSP policy. Most teams take the stylesheet path because it's also a maintainability win.

B

Trusted Types (XSS Sink Hardening)

Trusted Types not enabled

REVIEW

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.

C

Email Security

Action

DMARC: quarantine, SPF: ?all, DKIM

REVIEW

DMARC: quarantine, SPF: ?all, DKIM

DMARC policy is quarantine — good protection

SPF ends in ?all — provides no enforcement

?all (neutral) and +all (pass-everything) make the SPF record decorative. Receivers will accept any sender. Switch to -all (hard fail) or ~all (soft fail).

DKIM configured (selectors: fm3, fm1, fm2)

MTA-STS not configured

MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt.

TLS-RPT not configured

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>.

BIMI not configured

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.

DMARC

Policy quarantine — good protection Record v=DMARC1; p=quarantine; rua=mailto:10e8033c713f48bf88c5b5f514deb964@dmarc-reports.cloudflare.net,mailto:dmarc@akj.io; ruf=mailto:dmarc@akj.io; fo=1;

?all (neutral) and +all (pass-everything) make the SPF record decorative. Receivers will accept any sender. Switch to -all (hard fail) or ~all (soft fail).

Why this matters

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

MTA-STS forces inbound mail to use TLS, preventing downgrade attacks. Requires both a TXT record at _mta-sts.<domain> and a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt.

Why this matters

Without MTA-STS, inbound mail can be silently downgraded to plain SMTP by a network attacker.

Learn more ▾

MTA-STS (RFC 8461) tells sending mail servers to use TLS and to refuse delivery if TLS fails. Requires both a TXT record at _mta-sts.<domain> AND a policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt. Without it, an active attacker on the network path can strip STARTTLS and read the email in plaintext.

Source: RFC 8461

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.

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.

Got: removed

Expected: strict-origin-when-cross-origin

Why this matters

Weak Referrer-Policy values leak full URLs (with query params, tokens, IDs) to every third-party resource on the page.

Learn more ▾

Default referrer behavior shares the full referring URL with images, scripts, and other resources from third-party origins. If your URLs contain tokens, session IDs, or user emails (in query strings or paths), every third-party tracker gets them. Set `Referrer-Policy: strict-origin-when-cross-origin` (or stricter).

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.

X-Powered-By and similar headers (X-AspNet-Version, X-Runtime) tell attackers which versions to target. Disable in your server/framework config: PHP `expose_php=Off`, ASP.NET `<httpRuntime enableVersionHeader="false">`, Express `app.disable('x-powered-by')`.

Submit your domain to hstspreload.org to close the trust-on-first-use gap. Requires a preload-ready HSTS header (max-age=31536000+, includeSubDomains, preload).

Why this matters

Not in the Chrome preload list — first-time visitors over plain HTTP can be downgraded by a network attacker before HSTS kicks in.

Learn more ▾

The HSTS header only protects users who have already visited the site (TOFU window). Adding your domain to the Chrome preload list closes that gap so HSTS is enforced from the very first connection. Requires a preload-ready header (max-age=31536000+, includeSubDomains, preload) then submission at hstspreload.org. Inclusion ships in the next Chrome release after acceptance.

Without stapling, the browser performs a separate OCSP roundtrip on first connection -- adding latency and leaking the visited host to the CA. Enable OCSP stapling on your TLS server.

Why this matters

Without OCSP stapling, every first-time visitor pays an extra OCSP roundtrip — and the CA learns who's visiting your site.

Learn more ▾

OCSP stapling has the server fetch its own revocation status from the CA and attach the signed response to the TLS handshake. Without it, browsers contact the CA directly: extra latency for the user and a privacy leak (the CA sees who connected). Enable ssl_stapling on (nginx) / SSLUseStapling On (Apache) / OCSPStapling = on (Caddy auto-enables).
