Alternatives to 42Crunch on Buffalo

middleBrick is a self-service API security scanner that operates without agents or SDKs, making it applicable to Buffalo applications as well as other frameworks. You submit a target URL and receive a risk score from A to F with prioritized findings within under a minute. The scanner uses read-only methods (GET and HEAD) and text-only POST for LLM probes, so it does not modify your Buffalo services or require code changes.

The scanner covers 12 categories aligned to OWASP API Top 10 (2023), which maps findings to this standard and helps you prepare for related audit evidence. For Buffalo APIs, relevant detections include authentication bypass attempts, Broken Object Level Authorization (BOLA) via ID enumeration, Business Logic Abuse (BFLA) through admin endpoint probing, property over-exposure, input validation issues such as CORS misconfigurations, rate-limiting indicators, and data exposure patterns including PII and API key leakage. It also identifies insecure encryption practices, SSRF indicators, and versioning or fingerprinting concerns.

middleBrick parses OpenAPI 3.0, 3.1, and Swagger 2.0 files with recursive $ref resolution, cross-referencing spec definitions against runtime behavior. For Buffalo projects exposing an OpenAPI document, this reveals undefined security schemes or deprecated operations. Authenticated scanning is available in Starter and higher tiers, supporting Bearer, API key, Basic auth, and cookies. Domain verification is required, and only a limited set of headers is forwarded to prevent credential misuse.

The tool does not fix or patch findings; it reports issues with remediation guidance to help your team address vulnerabilities. You can integrate middleBrick into CI/CD with the GitHub Action, which can fail builds when the score drops below a chosen threshold. The CLI allows on-demand scans from any environment, and the Web Dashboard provides trend tracking and downloadable compliance PDFs. For automated workflows, an API client is available for custom integrations.

middleBrick includes LLM / AI Security testing with adversarial probes across Quick, Standard, and Deep scan tiers, covering system prompt extraction, instruction override, jailbreak patterns, data exfiltration attempts, and token smuggling. Continuous monitoring in Pro tier supports scheduled rescans, diff detection across scans, email alerts, and HMAC-SHA256 signed webhooks. Note that the scanner does not perform active SQL injection or command injection testing, and business logic vulnerabilities require human expertise.
