CSP is the most effective defense against XSS attacks. Add a Content-Security-Policy header to restrict resource loading.
default-src 'self'Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.

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.

DPermissions-PolicyActionNo header setFIX
No Permissions-Policy header set.
Without this header, embedded iframes can request access to sensitive device features.

CSP is the most important header for preventing XSS attacks. See the CSP section for detailed analysis.

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.

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.

BCORS ConfigurationNo CORS headersREVIEW
No CORS headers detected.
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

A+TLS & CertificatesTLS 1.2, 7 checks passedPASS
TLS 1.3 offers improved performance and security. Consider enabling it.
TLS 1.3 not in use — connection falls back to 1.2 and pays the extra round-trip.
Learn more ▾ ▴
Most clients prefer TLS 1.3 if both sides support it. If your server has TLS 1.3 enabled but it's not being negotiated, check for a downgrade-attack mitigation issue or a misconfigured cipher list. nginx ≥ 1.13.0 and OpenSSL ≥ 1.1.1 support TLS 1.3.

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.
