Security Headers

Action

3 of 10 headers properly configured

FIX

3 of 10 headers properly configured

HSTS max-age is too short (15552000s, should be ≥ 31536000s)

A short max-age leaves a window for downgrade attacks. Set max-age to at least 31536000 (1 year).

Got: max-age=15552000; includeSubDomains; preload Expected: max-age=31536000; includeSubDomains

X-Content-Type-Options header is missing

This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.

Expected: nosniff

X-Frame-Options is properly configured

Got: DENY

Referrer-Policy header is missing

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

Expected: strict-origin-when-cross-origin

Permissions-Policy header is missing

Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.

Expected: geolocation=(), camera=(), microphone=()

Content-Security-Policy is present

Got: default-src 'self' blob: commercial.cdn.aws.placeit.net commercial-staging.cdn.a…

Cross-Origin-Opener-Policy header is missing

COOP isolates your browsing context, preventing cross-origin side-channel attacks. Set to 'same-origin'.

Expected: same-origin

Cross-Origin-Embedder-Policy header is missing

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

Expected: require-corp

X-Powered-By header reveals technology stack

This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it.

Got: Next.js

Server header is present without version info

Got: cloudflare

A short max-age leaves a window for downgrade attacks. Set max-age to at least 31536000 (1 year).

Expected: max-age=31536000; includeSubDomains

Why this matters

Short HSTS max-age leaves a downgrade-attack window every time the cache expires — set ≥ 1 year.

Learn more ▾

max-age below 31536000 (1 year) is below industry recommendation. The browser forgets the HSTS policy and re-exposes first-visit downgrade attacks. Set to 63072000 (2 years) and add `includeSubDomains; preload` to qualify for the HSTS preload list.

Source: RFC 6797 / hstspreload.org

This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.

Expected: nosniff

Why this matters

MIME sniffing lets browsers run uploaded files as JavaScript, turning a file upload into an XSS.

Learn more ▾

Setting X-Content-Type-Options: nosniff tells browsers to trust your declared Content-Type instead of guessing. Without it, an attacker who uploads a polyglot file can sometimes get it executed as a script. One header, no downside.

Source: OWASP / MDN

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

Expected: strict-origin-when-cross-origin

Why this matters

Default 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.

Source: MDN / W3C

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-origin

Why 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-corp

Why 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.

Source: MDN / web.dev

This header discloses server technology (e.g. Express, PHP), helping attackers target known vulnerabilities. Remove it.

Why this matters

X-Powered-By: PHP/7.4.3 advertises your stack to attackers — disable it.

Learn more ▾

X-Powered-By and similar headers (X-AspNet-Version, X-Runtime) tell attackers which versions to target. Disable in your server/framework config: PHP `expose_php=Off`, ASP.NET `<httpRuntime enableVersionHeader="false">`, Express `app.disable('x-powered-by')`.

Permissions-Policy

Action

No header set

FIX

No header set

No Permissions-Policy header

Consider adding a Permissions-Policy header to restrict browser feature access from embedded content.

No Permissions-Policy header set.

Without this header, embedded iframes can request access to sensitive device features.

Suggested header

Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=()

upgrade-insecure-requests is not set

This directive upgrades HTTP resources to HTTPS automatically, preventing mixed content.

Expected: upgrade-insecure-requests

'unsafe-inline' allows inline <script> tags, defeating CSP against XSS. Remove it and use nonces or hashes instead.

Why this matters

Unsafe value (unsafe-inline, unsafe-eval) in script-src defeats CSP's main protection — XSS injections can execute again.

Learn more ▾

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.

Expected: upgrade-insecure-requests

Why this matters

Without 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.

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.
