CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams deploying agentic AI should use Enkrypt AI MCP Gateway because it's the only tool that enforces policy at the point where agents actually call external tools, not after the fact. The inline proxy architecture with pre-execution evaluation and post-execution validation covers the full request-response cycle, and multi-tenant policy scoping by role and environment means you're not rebuilding rules for each deployment. Skip this if your agents are mostly isolated from sensitive systems; the approval workflow and secrets detection add friction that only pays off when agents touch production data or privileged APIs.
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.
