CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading.

CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading.
Expected:
default-src 'self'Why this matters
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
Learn more ▾ ▴
Content-Security-Policy is the browser-enforced firewall against XSS. With a strict CSP, a script injection that would otherwise steal session cookies is silently blocked. Without it, your only defense is hoping every input on every form is escaped correctly forever. Start in Report-Only mode, fix violations, then graduate to enforcing.

CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis.
Expected:
default-src 'self'Why this matters
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Content-Security-Policy is the browser-enforced firewall against XSS. With a strict CSP, a script injection that would otherwise steal session cookies or rewrite the page is silently blocked. Without it, your only defense is hoping every input on every form is escaped correctly forever.

Without includeSubDomains, subdomains can still be accessed over HTTP.
Expected:
max-age=31536000; includeSubDomainsWhy this matters
Without 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.

Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
Expected:
geolocation=(), camera=(), microphone=()Why this matters
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'.
Expected:
same-originWhy this matters
COOP 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.

COEP prevents loading cross-origin resources without explicit permission. Required for SharedArrayBuffer and high-resolution timers.
Expected:
require-corpWhy 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.

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