Purpose and scope of automated API security scanning

Automated API security scanners provide continuous visibility into public-facing interfaces without requiring code changes. They surface misconfigurations, data exposures, and implementation weaknesses to help engineering teams maintain a strong security posture. These tools map findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II controls, and they surface findings relevant to audit evidence for common regulatory frameworks.

Black-box scanning approach and deployment constraints

middleBrick operates as a black-box scanner with no agents, SDKs, or code access. It supports any language, framework, or cloud using read-only methods (GET and HEAD) plus text-only POST for LLM probes, completing scans in under a minute. Sensitive endpoints are protected by a domain verification gate, and only a limited set of headers are forwarded, ensuring safe execution without modifying backend state.

Detection coverage across OWASP and common misconfigurations

The scanner covers 12 categories aligned to OWASP API Top 10, including Authentication bypass and JWT misconfigurations, BOLA and IDOR via adjacent ID probing, BFLA and privilege escalation attempts, and Property Authorization over-exposure. It also detects Input Validation issues such as CORS wildcards and dangerous methods, Rate Limiting anomalies, Data Exposure patterns including PII and API key formats, and Infrastructure misconfigurations like missing versioning and server fingerprinting.

Authenticated scanning, monitoring, and integration options

Authenticated scanning supports Bearer tokens, API keys, Basic auth, and cookies, restricted to an allowlist of headers and gated by domain ownership verification. Continuous monitoring on Pro plans provides scheduled rescans, diff detection, email alerts, and HMAC-SHA256 signed webhooks. The tool integrates via Web Dashboard, CLI, GitHub Action, MCP Server, and a programmable API to fit CI/CD workflows.

Limitations and responsible use guidance

The scanner does not perform active exploitation such as SQL injection or command injection, and it does not detect business logic vulnerabilities, blind SSRF, or provide remediation. It does not replace human pentesters for high-stakes audits. Use the output to prioritize manual review and apply secure coding practices based on the provided guidance.

Frequently Asked Questions

Which API security issues does the scanner actively detect?
It detects misconfigurations and exposures across authentication, authorization, input validation, data exposure, rate limiting, encryption, SSRF, inventory, unsafe consumption, and LLM/AI security, aligned to OWASP API Top 10.
Can authenticated scans be run against production APIs?
Yes, authenticated scanning is available for Starter tiers and above, provided domain ownership is verified and only safe, read-only methods are used.
How are new findings compared across scans?
Continuous monitoring on Pro tiers performs diff detection across scans, highlighting new findings, resolved findings, and score drift with configurable alerting.
Does the tool perform intrusive exploit testing?
No. The scanner is read-only and does not send destructive payloads, active SQL injection, or command injection tests.
What compliance mappings are provided?
Findings map to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II. Other frameworks are supported with alignment language for audit evidence.
