Best alternative to Wallarm

middleBrick positions itself as a focused, self-service API security scanner that emphasizes simplicity and broad compatibility over complex deployment. Unlike Wallarm, which relies on an agent or platform-specific integration, middleBrick operates as a black-box scanner requiring only a URL. It delivers a risk score from A to F with prioritized findings in under a minute, using read-only methods such as GET and HEAD, plus text-only POST for LLM probes. This approach suits teams that need quick, low-friction assessments without managing agents, SDKs, or code changes. It works across languages, frameworks, and cloud environments, making it a practical alternative for organizations that value deployment speed and minimal operational overhead.

middleBrick maps findings directly to three frameworks: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). The scanner covers 12 security categories aligned to OWASP API Top 10, including Authentication bypasses and JWT misconfigurations such as alg=none, HS256, expired tokens, missing claims, and sensitive data in claims. It detects BOLA and IDOR via sequential ID enumeration and active adjacent-ID probing, and identifies BFLA and privilege escalation through admin endpoint probing and role/permission leakage. Additional categories include Property Authorization over-exposure, Input Validation issues like CORS wildcard usage and dangerous HTTP methods, Rate Limiting and Resource Consumption signals, and Data Exposure patterns such as PII, Luhn-validated card numbers, API key formats, and error/stack-trace leakage. The tool also covers Encryption misconfigurations, SSRF indicators, Inventory Management gaps, Unsafe Consumption surfaces, and LLM/AI Security through 18 adversarial probes across Quick, Standard, and Deep tiers.

middleBrick parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution, cross-referencing spec definitions against runtime observations. This highlights undefined security schemes, sensitive fields, deprecated operations, and missing pagination. For authenticated scans, which require Starter tier or higher, the scanner supports Bearer, API key, Basic auth, and Cookie credentials. A domain verification gate ensures only the domain owner can scan with credentials, typically via DNS TXT record or an HTTP well-known file. The scanner is conservative in its network interactions: only specific headers such as Authorization, X-API-Key, Cookie, and X-Custom-* are forwarded, and destructive payloads are never sent.

The Web Dashboard provides a centralized interface to initiate scans, review reports, track score trends, and download branded compliance PDFs. The CLI, distributed as an npm package named middlebrick, enables scripted usage with middlebrick scan <url>, supporting JSON or text output for automation. A GitHub Action allows CI/CD gating, failing the build when the score drops below a configurable threshold. The MCP Server makes scanning accessible from AI coding assistants such as Claude and Cursor. An API client offers programmatic access for custom workflows. Continuous monitoring in Pro tier supports scheduled rescans every 6 hours, daily, weekly, or monthly, with diff detection across scans, email alerts rate-limited to one per hour per API, and HMAC-SHA256 signed webhooks that auto-disable after 5 consecutive failures.

middleBrick is a scanning tool and does not fix, patch, block, or remediate findings; it provides detection and actionable guidance. It does not perform active SQL injection or command injection tests, as those require intrusive payloads outside its scope. Business logic vulnerabilities are not detected, as they demand domain-specific human analysis. Blind SSRF is out of scope due to the absence of out-of-band infrastructure, and the tool does not replace a human pentester for high-stakes audits. These limitations are explicit to help you set accurate expectations and integrate the scanner effectively within a broader security program.
