Security Headers

✓Permissions-PolicyPresent

microphone=(), accelerometer=(), camera=(), gyroscope=(), interest-cohort=(), magnetometer=(), payment=(), sync-xhr=(), geolocation=(), fullscreen=(), autoplay=()

Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.

✓Referrer-PolicyPresent

strict-origin-when-cross-origin

Controls how much referrer information is sent with requests, preventing data leaks to third parties.

✓Strict-Transport-SecurityPresent

max-age=31536000; includeSubDomains

Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.

✗X-Content-Type-OptionsMissing

Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.

How to add it:

nginx

add_header X-Content-Type-Options "nosniff" always;

apache

Header always set X-Content-Type-Options "nosniff"

cloudflare

Rules > Transform Rules > Managed Transforms > Enable "Add X-Content-Type-Options header"

✗X-Frame-OptionsMissing

Prevents the page from being embedded in iframes, protecting against clickjacking attacks.

How to add it:

nginx

add_header X-Frame-Options "DENY" always;

apache

Header always set X-Frame-Options "DENY"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set X-Frame-Options to "DENY"

✓X-XSS-ProtectionPresent

1; mode=block

Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.

2 recommended security headers are missing on peri.lt.

Beyond headers: infrastructure exposure

via OSN, our sister project

Security headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
