🧠 What is SCA (Software Composition Analysis)?

SCA tools scan your codebase, build artifacts, and containers to:

• Detect known vulnerabilities (CVEs) in open-source libraries
• Flag license violations (GPL, MIT, etc.)
• Generate SBOMs (Software Bill of Materials)
• Suggest remediation or secure upgrades
