Security Headers
Action4 of 10 headers properly configured
4 of 10 headers properly configured
Critical::
HSTS header is missing
Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.
Expected: max-age=31536000; includeSubDomains
Warning::
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
Info::
X-Frame-Options is properly configured
Got: SAMEORIGIN
Warning::
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
Warning::
Permissions-Policy header is missing
Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features.
Expected: geolocation=(), camera=(), microphone=()
Info::
Content-Security-Policy is present
Got: default-src blob: data: https: 'unsafe-inline' 'unsafe-eval'; script-src 'self' …
Warning::
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
Warning::
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
Info::
X-Powered-By header is not present
Info::
Server header is present without version info
Got: nginx
Strict-Transport-Security forces browsers to use HTTPS, preventing downgrade attacks. Add the header with a max-age of at least 1 year.
Expected:
max-age=31536000; includeSubDomainsWhy this matters
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
Learn more ▾ ▴
HSTS tells browsers 'never speak HTTP to this domain again.' Without it, a network attacker (public WiFi, malicious ISP, hostile DNS) intercepts the first HTTP attempt and serves a downgraded version of your site. One header, big surface reduction.
Source: RFC 6797 / OWASP
This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'.
Expected:
nosniffWhy 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-originWhy 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-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.

'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.

Without base-uri, attackers can inject a <base> tag to hijack relative URLs. Set it to 'self' or 'none'.
Expected:
base-uri 'self'Why this matters
Missing base-uri in CSP leaves a base-tag injection attack path open even on otherwise strict policies.
Learn more ▾ ▴
A common omission: developers add CSP for script-src and frame-ancestors but forget base-uri. The result is a CSP that looks strict but lets an attacker rewrite every URL on the page via <base href>. Add `base-uri 'self'` to close the gap.
Source: MDN CSP
form-action restricts where forms can submit data, preventing form hijacking.
Expected:
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.
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/3, HSTS, and TLS version analysis
Info::
HTTP/3 (QUIC) not advertised
HTTP/3 eliminates head-of-line blocking. If your CDN supports it, consider enabling it.
Warning::
Missing Strict-Transport-Security header
HSTS tells browsers to only use HTTPS, preventing SSL stripping attacks.
Info::
TLS 1.3 in use (fastest handshake, 1-RTT)

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.
