CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Startup and SMB security teams adopting Claude Skills or similar AI agents need Caterpillar because it's the only free CLI scanner that catches permission escalation and credential theft in agent code before installation. It installs via curl with zero API key friction and covers both the ID.RA risk assessment and PR.PS platform hardening that NIST CSF 2.0 demands. Skip this if your organization needs post-deployment agent monitoring or runtime behavior analysis; Caterpillar stops threats at the gate, not in production.
Enterprise security teams deploying internal AI agents at scale need governance that stops prompt injection and unauthorized data flows before they happen, and Sonoma Security's MCP gateway enforcement does this without requiring agents to be rewritten. The self-hostable deployment and granular entitlement policies mean you can lock down agent behavior without waiting on vendor infrastructure or negotiating with your cloud provider. Skip this if your agents are mostly third-party SaaS integrations or if you need detection and response capabilities after compromise; Sonoma is built for prevention, not forensics.
