CORS Scannerv1.0.1

Before deploying a new API endpoint, run a CORS scan to ensure no misconfigurations exist that could expose sensitive data. The scanner checks for origin reflection, wildcard policies, and other common issues, assigning a security grade to streamline review.

When integrating with a partner API, verify that your CORS policy does not inadvertently trust malicious origins. Use the scanner to detect HTTP origin trust on HTTPS or subdomain wildcards that could be exploited.

As part of a security assessment, scan a client's web endpoints for CORS misconfigurations. The 13 checks cover critical issues like null origin acceptance and credential leaks, enabling comprehensive reporting with A-F grades.

Integrate the CORS scanner into CI/CD pipelines to automatically reject builds that introduce dangerous CORS policies. The --min-grade flag allows failing any deployment that scores below a C grade, ensuring security gates.

Scan internal web applications to verify they block cross-origin requests from external sites. The private network access check helps prevent attackers from using CORS to access internal resources via browser-based attacks.

Offer free access to basic scans (single URL, text output) and charge for batch scanning, JSON/markdown reports, and CI/CD integration features. Revenue comes from monthly subscriptions for advanced capabilities.

Security consultants bundle the scanner into their penetration testing services, providing automated CORS checks as a value-add. Charges are per-engagement or included in a retainer.

License the scanner to enterprises for use in their internal security toolchain. Offer site-wide or organization-wide licenses with priority support and custom integrations.
