What this scanner does for GDPR Article 32 assessment
GDPR Article 32 focuses on implementing appropriate security measures and demonstrating due diligence. middleBrick maps findings to controls referenced in the regulation to support audit evidence. The scanner runs a black-box assessment that stays read-only, so it does not modify production data or configuration. Within under a minute, you receive a risk score and prioritized findings that surface issues relevant to security of processing.
Detection scope aligned to API security controls
The scanner covers 12 categories aligned to OWASP API Top 10 (2023), which maps to widely referenced security controls. Detection capabilities include authentication bypass risks, broken object level authorization, privilege escalation paths, and exposure of sensitive data such as PII and API keys. It also flags CORS misconfigurations, unsafe HTTP methods, rate-limit header issues, and SSRF indicators that relate to resilience and data protection considerations.
- Authentication bypass, JWT misconfigurations, and security header checks
- IDOR and BOLA via sequential ID and adjacent endpoint probing
- Privilege escalation through admin endpoint discovery and role leakage
- Property over-exposure and mass-assignment surface
- CORS wildcard usage, dangerous methods, and debug endpoints
- Rate limits, oversized payloads, and unpaginated arrays
- PII, card data, key formats, and error data leakage
- HTTPS, HSTS, cookie flags, and mixed content
- SSRF indicators in URL and body fields
- Inventory issues like missing versioning and server fingerprinting
- Unsafe consumption surface and excessive third-party URLs
- LLM adversarial probes across tiered scan levels
OpenAPI analysis and authenticated scanning
The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution, cross-referencing the spec against runtime behavior. This helps identify undefined security schemes, deprecated operations, and missing pagination that may affect security and privacy controls. For authenticated scans, Bearer tokens, API keys, Basic auth, and cookies are supported. A domain verification gate ensures only the domain owner can run authenticated scans, and a strict header allowlist limits forwarded headers to Authorization, X-API-Key, Cookie, and X-Custom-*.

Pro tier enables scheduled rescans at intervals from 6 hours to monthly, with diff detection to highlight new findings, resolved items, and score drift. Alerts are rate-limited and delivered via email or HMAC-SHA256 signed webhooks that auto-disable after repeated failures. Integration options include a CLI for on-demand checks, a GitHub Action that can gate CI/CD, and an MCP server for AI coding assistants. These options allow teams to embed checks into existing workflows without replacing deeper assessments.
Limitations and posture
The scanner is a detection tool and does not fix, patch, or block issues. It does not test for blind SSRF via out-of-band channels, business logic flaws that require domain knowledge, or intrusive injection tests. Sensitive scan data is deletable on demand and purged within 30 days of cancellation. These constraints help set accurate expectations while maintaining a conservative safety posture.
