CSP Checker

Validate Content-Security-Policy configuration and identify weak directives before attackers can abuse them.

Best for teams validating CSP after adding new scripts, updating tag managers, tightening browser protections, or preparing an application for stronger XSS defenses.

Mode guidance: Quick mode is public for fast diagnostics. Comprehensive mode is reserved for account-backed workflows so results, follow-up, and broader analysis can stay tied to the right workspace.

What This Tool Checks

  • Directive-level risk scoring
  • Bypass pattern detection
  • Stack-specific remediation

Why It Matters

A weak Content-Security-Policy can leave room for script injection, unsafe third-party behavior, or policy bypasses that look harmless until a real exploit path appears.

Best For

Best for teams validating CSP after adding new scripts, updating tag managers, tightening browser protections, or preparing an application for stronger XSS defenses.

What To Do Next

Use the output to decide whether your next move is policy cleanup, staged report-only deployment, or stack-specific remediation on the pages that matter most.

What does the CSP Checker look for?

CSP Checker focuses on directive-level risk scoring, bypass pattern detection, stack-specific remediation. It is designed to help teams identify this category of weakness quickly and then move into broader workflows if deeper follow-up is needed.

What is the difference between Quick and Comprehensive mode?

Quick mode stays public for focused diagnostics. Comprehensive mode is intended for authenticated workflows where users need saved history, richer follow-up, and broader account-linked execution.

When should I use the full Vulnify platform instead?

Use the full platform when you need more than one focused diagnostic, want to keep reports and history, or need scheduled scans, exports, and broader vulnerability coverage beyond csp checker.
