Alternatives to 42Crunch on Echo

This scanner operates as a black-box solution that requires no agents, SDKs, or framework-specific instrumentation. You submit an API endpoint URL and receive a risk score with prioritized findings within one minute. It supports any language, framework, or cloud, making it applicable to services built on Echo without requiring code changes.

The scanner maps findings to OWASP API Top 10 (2023), covering common risks such as authentication bypass, IDOR, privilege escalation, and data exposure. It also aligns with PCI-DSS 4.0 and SOC 2 Type II control validation by surfacing configuration issues relevant to those frameworks. For other standards, the tool helps you prepare for audits and supports audit evidence collection through detected findings.

With Starter tier and above, you can scan APIs using Bearer tokens, API keys, Basic auth, and cookies. Domain verification is enforced via DNS TXT records or an HTTP well-known file to ensure only the domain owner can scan with credentials. The scanner forwards a restricted allowlist of headers, including Authorization, X-API-Key, Cookie, and X-Custom-*.

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution. It cross-references spec definitions against runtime behavior to identify undefined security schemes, sensitive field exposure, deprecated operations, and missing pagination. This helps validate design-time controls against actual runtime behavior for Echo-based services.

The scanner does not perform active SQL injection or command injection testing, as those require intrusive payloads outside its scope. It does not detect business logic vulnerabilities, blind SSRF, or guarantee any compliance status. For high-stakes audits, it is intended to complement, not replace, human-led penetration testing.
