OWASP Security Grade

100 / 100 Score

Evaluated against 6 industry-standard HTTP defensive headers.

A+

Header Compliance Checklist

Content-Security-Policy (CSP)PROTECTED

default-src 'self'; script-src 'self' 'unsafe-inline';

Prevents Cross-Site Scripting (XSS), data injection, and malicious asset execution.

Strict-Transport-Security (HSTS)PROTECTED

max-age=31536000; includeSubDomains; preload

Forces all browser traffic over HTTPS, preventing SSL stripping attacks.

X-Content-Type-OptionsPROTECTED

nosniff

Blocks MIME-type sniffing where browsers execute files with mismatched headers.

X-Frame-OptionsPROTECTED

DENY

Protects visitors from UI redressing and Clickjacking attacks inside iframes.

Referrer-PolicyPROTECTED

strict-origin-when-cross-origin

Protects user privacy by controlling how much referrer metadata is sent in HTTP requests.

Permissions-PolicyPROTECTED

geolocation=(), camera=(), microphone=()

Disables access to intrusive browser hardware features like camera and microphone.

Frequently Asked Questions

What is the most critical HTTP security header?

Content-Security-Policy (CSP) is widely considered the most vital defensive header because it directly stops Cross-Site Scripting (XSS) and data injection by strictly controlling allowed script origins.
