Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.
max-age=31536000; includeSubDomainsWithout HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

HSTS tells browsers 'never speak HTTP to this domain again.' Without it, a network attacker (public WiFi, malicious ISP, hostile DNS) intercepts the first HTTP attempt and serves a downgraded version of your site. One header, big surface reduction.

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

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.

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.

default-src provides a fallback for other directives. Set it to restrict default resource loading.
default-src 'self'Security gaps expose your site and users to attacks, eroding trust.
Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.
base-uri 'self'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'.

This only monitors, it doesn't block spoofed emails. Change to p=quarantine or p=reject after monitoring DMARC reports.
DMARC p=none collects reports but doesn't actually block spoofed mail — phishing emails still reach inboxes.
Learn more ▾ ▴
DMARC's three policies are p=none (monitor only), p=quarantine (mark as spam), and p=reject (bounce). Most domains start at p=none to gather data, but stay there forever, leaving spoofers unblocked. After 30 days of clean DMARC reports, graduate to p=quarantine, then p=reject.

Without rua=, you have no visibility into spoof attempts or auth failures from your own legitimate senders. Add rua=mailto:dmarc@<your-domain> (or a managed inbox at a reporting service).

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.

A+TLS & CertificatesTLS 1.3, 8 checks passedPASS
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).
