Pricing structure and volume model
MiddleBrick uses a straightforward per-API pricing model with no hidden seat or overage fees. The Free tier allows three scans per month via CLI, which is suitable for initial proof-of-concept work. The Starter tier at 99 dollars per month supports up to 15 APIs, with monthly scans, a web dashboard, email alerts, and the MCP Server. The Pro tier at 499 dollars per month covers 100 APIs, with an additional 7 dollars for each API beyond that limit, adding continuous monitoring, GitHub Action gates, and compliance report downloads. The Enterprise tier is typically 2000 dollars per month and above, providing unlimited APIs, custom rules, SSO, audit logs, and dedicated support.
Total cost of ownership factors
Beyond the sticker price, consider the operational overhead of each option. Because MiddleBrick is a black-box scanner, there is no need to install agents, modify source code, or integrate SDKs, which reduces implementation time and avoids dependency risk. Scan initiation from the CLI or automation pipelines is lightweight, and the platform handles maintenance so teams do not need dedicated scanning infrastructure. With authenticated scans, domain verification ensures that only the rightful owner can submit credentials, which reduces configuration errors that could otherwise lead to repeated runs or support overhead. Data management is streamlined through on-demand deletion and automatic purging within 30 days of cancellation, limiting long-term storage concerns.
Feature coverage aligned to compliance frameworks
MiddleBrick maps findings to OWASP API Top 10 (2023), PCI-DSS 4.0, and SOC 2 Type II, providing structured guidance that can support audit evidence collection. The scanner detects issues such as authentication bypass, JWT misconfigurations, IDOR, privilege escalation, and data exposure patterns like PII and API key leakage. It also identifies input validation risks including CORS misconfigurations and dangerous HTTP methods, as well as SSRF indicators related to URL-accepting parameters. For LLM-facing APIs, dedicated adversarial probes cover prompt extraction, jailbreak attempts, and token smuggling, helping you understand model-facing risk surfaces. While the tool does not remediate, it supplies context and remediation guidance to accelerate internal fixes.
Operational workflows and automation
The platform supports both human and machine-driven workflows. The Web Dashboard centralizes scan results, score trends, and downloadable compliance PDFs, making it easy to share findings with stakeholders. The CLI enables scripting and CI/CD integration, allowing commands such as middlebrick scan <url> to produce JSON or text output for downstream processing. The GitHub Action can enforce quality gates by failing builds when scores drop below a defined threshold. For environments requiring tighter integration, the MCP Server allows AI coding assistants to trigger scans, and the API client supports custom integrations. Pro tier adds scheduled rescans every six hours, daily, weekly, or monthly, with diff detection that highlights new findings, resolved items, and score drift.
Limitations and responsible use
MiddleBrick is a scanning tool and does not replace comprehensive security practices. It does not perform active SQL injection or command injection testing, as those require intrusive payloads outside its design scope. Business logic vulnerabilities are also outside its coverage, as they demand domain-specific understanding. Blind SSRF and other out-of-band infrastructure checks are not performed, and the tool should not be relied upon as the sole method for high-stakes audits. It does not fix, patch, block, or certify systems, and any compliance claims should be validated through appropriate audit processes.
