Beagle Security

Beagle Security is an automated web application penetration testing tool designed to help you proactively secure your online assets.

It provides you with clear, actionable remediation steps so your development team can patch vulnerabilities quickly without needing deep security expertise.

The platform integrates directly into your CI/CD pipeline, allowing you to catch security issues during the development phase rather than after deployment.
