42Crunch API Audit is a commercial api security tool by 42Crunch. Levo Runtime Application Security is a commercial api security tool by Levo. Compare features, ratings, integrations, and community reviews side by side to find the best api 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:
Development teams shipping APIs at scale need 42Crunch API Audit to catch security gaps before code reaches production; its 300+ checks against OpenAPI contracts surface misconfigurations that static code analysis and WAFs typically miss entirely. The tool integrates directly into GitHub Actions and VS Code workflows, meaning security issues land in the developer's IDE rather than creating a separate audit queue weeks later. Skip this if your organization hasn't standardized on OpenAPI specs or if you need runtime API monitoring and threat detection; 42Crunch is a design-phase tool, not a request-level firewall.
Levo Runtime Application Security
Teams building AI-native applications or maintaining sprawling API ecosystems should choose Levo Runtime Application Security because it actually discovers and monitors machine-to-machine traffic that traditional WAFs and API gateways miss. The eBPF-based collection works without agents, and the unified runtime graph connecting APIs, LLMs, and agents gives you visibility into attack surfaces that don't show up in your inventory tools. Skip this if your infrastructure is mostly monolithic, on-prem applications with minimal API footprint; you'll pay for capabilities you don't need.
