Best alternative to Tenable for API security
For teams prioritizing API security, Tenable’s broad coverage often introduces noise and a steep learning curve when the focus is APIs. middleBrick positions itself as a better alternative when the primary need is continuous, low-friction visibility into API risk rather than network-centric compliance noise. It maps findings to OWASP API Top 10 (2023), supports audit evidence for SOC 2 Type II, and aligns with security controls described in PCI-DSS 4.0 without requiring infrastructure changes.
Black-box scanning approach
middleBrick operates as a black-box scanner, which reduces operational complexity compared to agents or SDK-dependent solutions. It does not require access to source code, containers, or CI pipelines, making it applicable across any language, framework, or cloud environment. The scanner uses read-only methods (GET and HEAD) and text-only POST for LLM probes, completes most scans in under a minute, and blocks private IPs, localhost, and cloud metadata endpoints at multiple layers to ensure safe execution.
Detection coverage aligned to standards
The scanner covers 12 security categories aligned to OWASP API Top 10 (2023), including authentication bypass, JWT misconfigurations, BOLA and BFLA, sensitive data exposure, input validation issues, SSRF indicators, and LLM-specific adversarial probes. It parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution and cross-references spec definitions against runtime behavior to highlight undefined security schemes, deprecated operations, and sensitive field exposure. While it surfaces findings relevant to HIPAA and GDPR alignment, it does not claim compliance with these frameworks.
Deployment and integration flexibility
middleBrick supports multiple consumption models to fit existing workflows. The web dashboard provides scan management, score trends, and downloadable compliance PDFs. The CLI npm package enables scripted scans with JSON or text output, and the GitHub Action acts as a CI/CD gate that fails builds when scores drop below a chosen threshold. An MCP server allows scans from AI coding assistants, and a programmable API supports custom integrations. Pro tier adds scheduled rescans, diff detection, email alerts, HMAC-SHA256 signed webhooks, and Slack or Teams notifications.
Limitations and responsible use
middleBrick is a detection tool and does not fix, patch, block, or remediate findings. It does not perform active SQL injection or command injection testing, and it does not detect business logic vulnerabilities or blind SSRF, which require domain context and human analysis. High-stakes audit scenarios still necessitate a human pentester. The tool reports what it finds with remediation guidance and does not replace expert security review.
