About the security tools
Security is a field where open source is objectively stronger than closed solutions: a tool whose code anyone can audit deserves more trust. Nearly the entire toolkit of security professionals is open.
The collection includes scanners, analyzers, and security learning materials. Use them ethically: on your own systems or within authorized engagements.
