Without includeSubDomains, subdomains can still be accessed over HTTP.
max-age=31536000; includeSubDomainsWithout includeSubDomains, a forgotten dev subdomain over HTTP can set malicious cookies that ride to the apex.
Learn more ▾ ▴
HSTS without includeSubDomains protects only the exact domain. Cookies set on a non-HSTS subdomain can ride to the apex via cookie-scope attacks. The fix is one directive append. Verify all subdomains support HTTPS first — adding includeSubDomains to a domain with HTTP-only subdomains breaks them.

strict-origin-when-cross-originWeak 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).

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.

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.

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.

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.

'unsafe-inline' allows inline <script> tags, defeating CSP against XSS. Remove it and use nonces or hashes instead.
Unsafe value (unsafe-inline, unsafe-eval) in script-src defeats CSP's main protection — XSS injections can execute again.

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.

This directive upgrades HTTP resources to HTTPS automatically, preventing mixed content.
upgrade-insecure-requestsWithout upgrade-insecure-requests, any HTTP subresource link survives as a mixed-content warning instead of auto-upgrading.
Learn more ▾ ▴
Adding `upgrade-insecure-requests` to your CSP turns every http:// subresource fetch into https:// at the browser layer. One-line defense against accidental mixed content from legacy links or third-party widgets.

Cross-origin requests are blocked by browser same-origin policy.
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

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.
