Caterpillar is a free agentic ai security tool by Alice. Discover AI is a commercial agentic ai security tool by Straiker. Compare features, ratings, integrations, and community reviews side by side to find the best agentic ai security fit for your security stack.
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 managing sprawling Claude, Bedrock, and Copilot deployments will get immediate value from Discover AI's automated agent inventory and permission auditing, which catches shadow AI and misconfigured integrations that traditional CSPM misses entirely. The tool covers four NIST CSF 2.0 functions including continuous monitoring and supply chain risk, which matters because agent ecosystems create attack surface that asset management tools don't see. Skip this if your agentic footprint is still experimental or confined to a single platform; Discover AI assumes you're already running multiple agent frameworks and need visibility across all of them.
