FAQPage Schema
How do I audit HTTP security headers for my web application?▼

Auditing HTTP security headers involves inspecting web application responses for missing or misconfigured settings like HSTS, X-Frame-Options, and CSP. This detects header-related misconfigurations and produces actionable remediation guidance.

What HTTP security headers should I check to protect my web app?▼

Essential security headers to verify include HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and CSP. Checking these headers strengthens web app defenses and reduces exposure to common vulnerabilities.

Can I integrate a security header audit into a CI/CD deployment pipeline?▼

Yes, security header audits integrate into CI/CD pipelines and manual reviews. The process applies reproducible rules across servers and frameworks, detecting misconfigurations and providing audit-ready evidence for deployment.

Why do my cookie attributes need to be checked during a security header review?▼

Checking cookie attributes during a security header review is necessary because misconfigured flags expose web apps to vulnerabilities. Measuring cookie security alongside HTTP headers ensures comprehensive defense and yields audit-ready evidence.

Does this security header audit work across different web servers and frameworks?▼

Yes, security header audits apply to web applications across diverse servers and frameworks. The process uses reproducible rules to consistently identify missing or misconfigured headers regardless of the underlying environment.
