Security headers check for client websites
Pentestr helps teams find missing HTTP security headers and turn them into fixable remediation steps before client handoff.
Agencies and developers responsible for production website configuration.
Security headers are easy to miss, especially across many client sites and hosting platforms.
A clear list of missing headers and practical configuration guidance.
Headers are small but visible
Missing headers are often simple to fix, but they are also easy for automated reviewers and security-conscious clients to spot.
Make header checks part of QA
Adding security headers to launch QA helps agencies catch regressions before production delivery.
Pair headers with broader exposure checks
Headers are one layer. Pentestr also checks TLS, WAF, exposed services, email security, and known public findings.
