Alternatives to 42Crunch for Nightly scheduled scan

A nightly schedule requires an API security scanner that runs quickly, needs minimal maintenance, and avoids access to source code or infrastructure. middleBrick is a self-service black-box scanner you can trigger on a schedule without coordinating with development teams. Submit a URL, receive a risk score from A to F with prioritized findings, and complete a scan in under a minute using read-only methods. This makes it suitable for recurring checks in CI/CD pipelines or external monitoring workflows.

middleBrick maps findings directly to OWASP API Top 10 (2023) and supports audit evidence for related controls. Detection categories include authentication bypass, JWT misconfigurations such as alg=none and expired tokens, BOLA and IDOR via sequential ID probing, BFLA and privilege escalation attempts, input validation issues like CORS wildcard usage, rate-limiting indicators, data exposure including PII and API key patterns, and SSRF probes against URL-accepting parameters. The scanner also covers LLM/AI security with adversarial prompts across multiple tiers.

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime behavior. For authenticated scans, which are available from Starter tier upward, you can provide Bearer tokens, API keys, Basic auth, or cookies. Domain verification is enforced through DNS TXT records or an HTTP well-known file so that only the domain owner can submit credentials. A header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.

You can run scans via the CLI using middlebrick scan <url> with JSON or text output, through the web dashboard for reporting and score trends, or via the GitHub Action to gate CI/CD builds when the score drops below a threshold. An MCP server enables scanning from AI coding assistants, and a programmable API supports custom integrations. Pro tier adds scheduled rescans every 6 hours, daily, weekly, or monthly, with diff detection and email alerts limited to one per hour per API.

middleBrick operates as a read-only scanner and never sends destructive payloads. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer data is deletable on demand and purged within 30 days of cancellation. It is not used for model training and is never sold. The tool does not fix, patch, or block issues; it reports findings with remediation guidance and explicitly does not perform active SQL or command injection testing or detect business logic vulnerabilities.
