API security for Enterprise organizations

Enterprise organizations operate with distributed architectures, multiple business units, and strict risk thresholds. The surface area for API interactions is large, and unmanaged exposure can lead to data loss and regulatory scrutiny. A self-service scanner that requires no agents or code changes can fit into existing governance workflows by providing a consistent, repeatable assessment of external endpoints.

Black-box scanning analyzes live endpoints using read-only methods such as GET and HEAD, with text-only POST reserved for LLM probes. The scanner resolves OpenAPI 3.0, 3.1, and Swagger 2.0 definitions, including recursive $ref resolution, and cross-references spec definitions against runtime behavior. Detection capabilities span 12 categories aligned to the OWASP API Top 10 (2023), including authentication bypass, sensitive data exposure, injection surfaces, and LLM security probes across multiple tiers.

• Authentication issues such as JWT misconfigurations, algorithm confusion, and security header misalignment.
• Broken Object Level Authorization and Insecure Direct Object References through ID enumeration and adjacent-ID probing.
• Property over-exposure and mass-assignment risks revealing internal fields.
• Input validation gaps including CORS misconfigurations and dangerous HTTP methods.
• Data exposure patterns identifying emails, credit card numbers, API keys, and error leakage.
• LLM-specific adversarial testing covering prompt extraction, jailbreaks, and token smuggling.

Authenticated scanning is available in the Starter tier and above, supporting Bearer tokens, API keys, Basic authentication, and cookies. Domain verification is enforced through DNS TXT records or an HTTP well-known file, ensuring only the domain owner can submit credentials. Request headers are restricted to an allowlist containing Authorization, X-API-Key, Cookie, and X-Custom-* headers, minimizing unintended data exposure during scans.

Continuous monitoring options include scheduled rescans at six-hour, daily, weekly, or monthly intervals, with diff detection to highlight new findings, resolved findings, and score drift. Alerts are rate-limited to one notification per hour per API and delivered via email or HMAC-SHA256 signed webhooks with auto-disable after five consecutive failures.

The platform supports multiple consumption models for enterprise teams. The Web Dashboard provides centralized scan management, score trend analysis, and downloadable compliance reports. The CLI enables on-demand scans from development environments using a command such as middlebrick scan https://api.example.com, with JSON or text output for automation pipelines. A GitHub Action allows CI/CD gating based on score thresholds, while an MCP Server integrates scanning into AI-assisted development tools.

For organizations with custom workflows, an API client offers programmatic access to initiate scans and retrieve results. This flexibility supports integration into existing security operations without requiring changes to application code or infrastructure.

It is important to understand the scope of what the scanner does and does not do. The tool does not perform remediation, patch code, or block traffic; it detects and reports findings with guidance for mitigation. It does not execute active SQL injection or command injection tests, which require intrusive payloads outside the intended scope. Business logic vulnerabilities, blind SSRF, and certain infrastructure-level issues require human expertise aligned with your domain context.

Findings map directly to three frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). For other regulations, the scanner supports audit evidence collection and aligns with security controls described in relevant frameworks, without asserting certification or guaranteed compliance.
