42Crunch API Scan is a commercial api security tool by 42Crunch. Hypernative Firewall is a commercial api security tool by Hypernative. 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:
Teams shipping APIs built on OpenAPI specs need 42Crunch API Scan to catch contract violations and injection flaws before production; its real traffic simulation finds what static analysis misses. The tool covers OWASP API Security Top 10 issues and integrates directly into VS Code and GitHub Actions, meaning security checks happen at commit time, not weeks later in a separate scan cycle. Skip this if your APIs aren't documented in OpenAPI format or if you need broader web application scanning beyond API endpoints; 42Crunch is deliberately API-focused, which is exactly why it works.
Protocol teams and DeFi platforms need Hypernative Firewall because it stops malicious transactions before they execute, not after they drain liquidity. The firewall operates at 7K gas per check, making it economical enough to run on every transaction, and its execution logic analysis catches exploit patterns that simple allowlist filtering misses. Skip this if your organization needs post-incident forensics or cross-chain orchestration; Hypernative prioritizes real-time blocking on a single chain and assumes you can tolerate the operational overhead of managing client-defined rulesets.
