Expected:
DENYWhy this matters
Without frame protection, your site can be embedded in a hostile page and used for clickjacking.
Learn more ▾ ▴
Clickjacking overlays your site under a transparent malicious page so users click invisible buttons. Setting X-Frame-Options: DENY (or a modern frame-ancestors CSP directive) blocks the embedding entirely. There's almost never a legitimate reason to allow it.
Source: OWASP / MDN
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.
Source: MDN / W3C
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.
Source: MDN / web.dev
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.

form-action 'self'Why this matters
Security gaps expose your site and users to attacks, eroding trust.
This directive upgrades HTTP resources to HTTPS automatically, preventing mixed content.
Expected:
upgrade-insecure-requestsWhy this matters
Without upgrade-insecure-requests, any HTTP subresource link survives as a mixed-content warning instead of auto-upgrading.

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.

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.
