FEmail SecurityActionno DMARC, no SPFFIX
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.
Without DMARC, anyone can send phishing emails using your domain name.

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.

Without SPF (Sender Policy Framework), receivers can't tell which servers are authorized to send mail for your domain. Add a TXT record at the apex starting with v=spf1, ending in -all.
Security gaps expose your site and users to attacks, eroding trust.
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.
No DKIM signature on outbound mail — receivers can't cryptographically prove the message came from your domain.

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.

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

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>.
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.
Security gaps expose your site and users to attacks, eroding trust.
DPermissions-PolicyActionNo header setFIX
No Permissions-Policy header set.
Without this header, embedded iframes can request access to sensitive device features.
Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=()
BSecurity Headers6 of 10 headers properly configuredREVIEW
Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
geolocation=(), camera=(), microphone=()Permissions-Policy locks down browser APIs you don't use — without it, every page can request camera/mic/geolocation if XSS lands.
Learn more ▾ ▴
By default every page can request the camera, microphone, geolocation, payment APIs, and dozens more. Permissions-Policy turns off the ones you don't need so a future bug can't quietly start using them. It's a defense-in-depth header — one line, big surface reduction.

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

The Server header discloses the software version, aiding attackers in targeting known vulnerabilities. Remove the version number.
Server: nginx/1.18.0 tells attackers exactly which CVEs to test — strip the version string.
Learn more ▾ ▴
Server version disclosure helps attackers select exploits matching your stack. Configure your server to omit the version (nginx: `server_tokens off;`, Apache: `ServerTokens Prod`). Doesn't fix vulnerabilities but removes the easy reconnaissance step.

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).
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.

Origin reflection test
Some servers mirror the request Origin header, which can be exploited. Test manually:
curl -sI -H "Origin: https://evil.com" <url> | grep -i access-control

frame-ancestors controls who can embed your page, preventing clickjacking. Set it to 'self' or 'none'.
frame-ancestors 'self'Security gaps expose your site and users to attacks, eroding trust.
A report-only policy is active alongside the enforcing policy for monitoring.
Running enforcing + Report-Only in parallel lets you test stricter directives safely before promoting them.

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

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.
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).
