- Continuous monitoring with scheduled rescans and webhooks
Overview and scope
This tool is a self-service API security scanner that accepts a URL and returns a risk score from A to F with prioritized findings. It performs black-box scanning only, using read-only methods (GET and HEAD) plus text-only POST for LLM probes. Scan completion typically occurs in under a minute, and no agents, SDKs, or code access are required. It works across any language, framework, or cloud target.
Detection coverage aligned to standards
The scanner maps findings to three frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). It detects 12 security categories that align with these standards and common gaming threat models, including:
- Authentication bypass, JWT misconfigurations, and security header issues
- BOLA and IDOR via sequential ID enumeration and active adjacent-ID probing
- BFLA and privilege escalation through admin endpoint probing and role leakage
- Property authorization over-exposure and mass-assignment surface
- Input validation gaps such as CORS wildcard usage and dangerous HTTP methods
- Rate limiting visibility, oversized responses, and unpaginated arrays
- Data exposure including PII patterns, API key formats, and error leakage
- Encryption checks like HTTPS redirects, HSTS, and cookie flags
- SSRF probes targeting URL-accepting parameters and internal IP detection
- Inventory issues such as missing versioning and server fingerprinting
- Unsafe consumption surface including excessive third-party URLs and webhooks
- LLM / AI Security with 18 adversarial probes across Quick, Standard, and Deep tiers
OpenAPI and authenticated scanning
The scanner parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, then cross-references spec definitions against runtime findings to highlight undefined security schemes, sensitive fields, deprecated operations, and missing pagination. Authenticated scanning is available from the Starter tier upward, supporting Bearer, API key, Basic auth, and Cookie credentials. Domain verification is enforced via DNS TXT record or HTTP well-known file, ensuring only the domain owner can scan with credentials. A strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.
Product formats and continuous monitoring
The Web Dashboard centralizes scans, report viewing, score trend tracking, and branded compliance PDF downloads. The CLI npm package supports commands such as middlebrick scan <url> with JSON or text output. A GitHub Action provides CI/CD gating, failing the build when the score drops below a set threshold. The MCP Server enables scanning from AI coding assistants. Continuous monitoring in the Pro tier includes scheduled rescans every 6 hours, daily, weekly, or monthly; diff detection for new and resolved findings; email alerts rate-limited to 1 per hour per API; and HMAC-SHA256 signed webhooks that auto-disable after 5 consecutive failures.
Safety posture and limitations
The scanner uses read-only methods only and never sends destructive payloads. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Customer scan data is deletable on demand and purged within 30 days of cancellation; data is never sold or used for model training. This tool does not fix, patch, block, or remediate findings, nor does it perform active SQL injection or command injection testing. It does not detect business logic vulnerabilities, blind SSRF, or replace a human pentester for high-stakes audits. Its role is to detect and report with remediation guidance.
