Why teams look for a Socket alternative

The reasons teams outgrow Socket are fairly consistent:

  • Focused specifically on supply chain security — does not replace broader SCA tools for CVE tracking, license compliance, and dependency management.
  • Behavioral scanning occasionally flags legitimate packages with unusual install behavior — teams need to tune policies to balance security and developer friction.
