  • Integration options including CLI, GitHub Action, and MCP Server

Black-box API Security Scanning

This scanner operates as a black-box solution. It requires no agents, SDKs, or code access and supports any language, framework, or cloud environment. You submit a URL and receive a risk score from A to F with prioritized findings. Scan completion is typically under one minute, using read-only methods such as GET and HEAD, with text-only POST for LLM probes. The approach is non-intrusive and does not modify, patch, or block any system behavior.

Detection Scope and Compliance Mapping

The scanner covers 12 security categories aligned to the OWASP API Top 10 (2023). It detects authentication bypasses, JWT misconfigurations, broken object level authorization, privilege escalation, property over-exposure, input validation issues, rate limiting deficiencies, data exposure risks, encryption misconfigurations, SSRF indicators, inventory management gaps, and LLM/AI security threats. Findings map directly to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023), helping you prepare for audit evidence and aligning with security controls described in these frameworks.

Authenticated Scanning and Safety Controls

Authenticated scanning is available from the Starter tier and above, supporting Bearer tokens, API keys, Basic authentication, and cookies. A domain verification gate ensures only the domain owner can scan with credentials. The scanner enforces a strict header allowlist, forwarding only Authorization, X-API-Key, Cookie, and X-Custom-* headers. Safety controls include blocking private IPs, localhost, and cloud metadata endpoints at multiple layers, and scanning is read-only with no destructive payloads.

OpenAPI Specification Analysis

The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution. It cross-references spec definitions against runtime findings to identify undefined security schemes, sensitive fields, deprecated operations, and missing pagination. This helps surface specification deviations that may expose unintended behavior or weak security definitions in your API design.

Products, Integrations, and Continuous Monitoring

The platform provides a Web Dashboard for scanning, report viewing, score trend tracking, and downloadable compliance PDFs. The CLI enables commands such as middlebrick scan <url> with JSON or text output. A GitHub Action can gate CI/CD pipelines, failing builds when scores drop below a threshold. The MCP Server allows scans from AI coding assistants. Pro tier adds scheduled rescans, diff detection, email alerts, signed webhooks, and Slack or Teams notifications. Enterprise tiers support unlimited APIs, custom rules, SSO, audit logs, SLA-backed support, and dedicated assistance.

Frequently Asked Questions

What is the difference between free and paid tiers?
The free tier allows 3 scans per month with CLI access. Starter adds 15 APIs, monthly scans, dashboard, email alerts, and MCP Server. Pro includes continuous monitoring, more APIs, GitHub Action gates, and compliance features. Enterprise offers unlimited APIs and dedicated support.
Does the scanner perform active exploitation like SQL injection?
No. The scanner is read-only and does not perform active SQL injection or command injection. Those activities are outside the scope and require intrusive testing methodologies.
Can the scanner detect business logic flaws?
Business logic vulnerabilities require human expertise tied to your domain. The scanner detects indicators and patterns but does not replace contextual analysis by security professionals.
How is scan data handled and stored?
Customer scan data can be deleted on demand and is purged within 30 days of cancellation. Data is never sold and is not used for model training.
