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 151 chars of text -- likely empty / placeholder
After HTML stripping, the page body contains 151 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: 151 chars

Subresource Integrity Adoption
Action
0% SRI adoption (0/10 third-party resources)
FIX
0% SRI adoption (0/10 third-party resources)
Warning::
SRI adoption: 0/10 third-party resources protected (0%)
Of 10 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://static.whatsapp.net/rsrc.php/v5/yd/l/0,cross/I3Bnu8ALToVKkmsA6qiUsNOB_OY8k1KqH.css - https://static.whatsapp.net/rsrc.php/v4/yA/r/yNZV7jdVFoC.js - https://static.whatsapp.net/rsrc.php/v4/yX/r/6XAglkoVXjF5SP815S78jCXCeRHSjJ3XszSzQ0VN_3NPOcvegDn2UeDg7zQlmispEi2DoNJSuXYKcibJkO_PKzLne0qnL2dG90HKa8aOC8-JP_rO1GHH6N2XQfibXh0vdaWGso6pjbbzH2b.js - https://static.whatsapp.net/rsrc.php/v4/y0/r/eDg9cFyXmNS.js - https://static.whatsapp.net/rsrc.php/v4/yF/r/ODeFkUjI7ok.js 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.

FIX
no DMARC, SPF: ~all
Warning::
No DMARC record found
Without DMARC, email receivers have no policy for handling authentication failures. Add a TXT record at _dmarc.<domain> starting with v=DMARC1.
Info::
SPF ends in ~all (soft fail)
Soft fail tells receivers to accept-but-mark unauthorized mail. Migrate to -all once you've confirmed all legitimate senders are listed (DMARC aggregate reports help verify).
Info::
No DKIM detected via common selectors
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.
Info::
MTA-STS not configured

DMARC

No DMARC record found

Without DMARC, email receivers have no policy for handling authentication failures from your domain.

Without DMARC, email receivers have no policy for handling authentication failures. Add a TXT record at _dmarc.<domain> starting with v=DMARC1.

Why this matters

Without DMARC, anyone can send phishing emails using your domain name.

Learn more ▾

DMARC tells receiving mail servers what to do with email that fails SPF/DKIM checks for your domain. With a strict 'p=reject' policy, spoofed emails get bounced; without it they reach the inbox. Domains used in phishing campaigns lose deliverability and brand trust fast.

Source: DMARC.org / NIST

Soft fail tells receivers to accept-but-mark unauthorized mail. Migrate to -all once you've confirmed all legitimate senders are listed (DMARC aggregate reports help verify).

Why this matters

Informational: a labeled value pair from the audit.

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.

Source: RFC 6376 / Google + Yahoo 2024 sender requirements

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.

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.

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.

'unsafe-eval' allows eval() and similar functions, enabling code injection. Remove it.

Why this matters

Unsafe value (unsafe-inline, unsafe-eval) in script-src defeats CSP's main protection — XSS injections can execute again.

Learn more ▾

unsafe-inline allows inline <script> tags; unsafe-eval allows eval() and similar. Both are necessary for some legacy code but explicitly dangerous. Migrate to nonces (per-page random tokens) or hashes (per-script SHA-256) instead.

Source: OWASP CSP / MDN

Set object-src to 'none' to prevent Flash/Java plugin exploits.

Expected: object-src 'none'
Why this matters

object-src open in CSP allows Flash/PDF/plugin embedding — a now-deprecated attack vector that should be explicitly blocked.

Learn more ▾

object-src controls <object>, <embed>, and <applet> elements. Modern sites have no need for plugins; setting `object-src 'none'` blocks an entire class of legacy XSS vectors at zero cost. If your CSP missed it, add the directive.

Source: MDN CSP

Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.

Expected: base-uri 'self'
Why this matters

Missing base-uri in CSP leaves a base-tag injection attack path open even on otherwise strict policies.

Learn more ▾

A common omission: developers add CSP for script-src and frame-ancestors but forget base-uri. The result is a CSP that looks strict but lets an attacker rewrite every URL on the page via <base href>. Add `base-uri 'self'` to close the gap.

frame-ancestors controls who can embed your page, preventing clickjacking. Set it to 'self' or 'none'.

Expected: frame-ancestors 'self'
Why this matters

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.

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.

Renew the certificate before it expires to avoid browser warnings.

Why this matters

Cert expiry within the renewal window — fix now while there's no user impact, instead of after expiry when there's a full outage.

Most CAs recommend renewal at 30 days remaining. Inside that window, schedule the renewal immediately and verify auto-renewal is configured if applicable. Don't wait until 7 days; weekend / holiday timing can leave you exposed.

Source: Let's Encrypt / CA renewal best practice

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).

The Permissions-Policy header explicitly declares policies for 10/10 high-risk features. Covered: camera, microphone, geolocation, payment, usb, serial, midi, accelerometer, gyroscope, magnetometer Not declared (default-allow): 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.
