Purpose and scope of API security scanning
API security for seed-stage products must balance speed with risk coverage. This scanner performs black-box assessments against public-facing endpoints without requiring code access or agents. It focuses on detection and reporting rather than remediation, providing a repeatable way to surface issues as your API surface grows.
Detection coverage aligned to industry standards
The scanner evaluates 12 security categories aligned to the OWASP API Top 10 (2023) and maps findings to PCI-DSS 4.0 and SOC 2 Type II controls. Detection includes authentication bypasses, JWT misconfigurations such as alg=none or expired tokens, BOLA and IDOR via sequential ID probing, BFLA and privilege escalation attempts, over-exposed properties, input validation issues like CORS wildcards and dangerous HTTP methods, rate-limit header visibility, PII and API key exposure, encryption misconfigurations, SSRF probes against URL-accepting inputs, and inventory management gaps. An LLM security track runs 18 adversarial probes across Quick, Standard, and Deep tiers to test for system prompt extraction, jailbreak techniques, data exfiltration, and token smuggling.
OpenAPI analysis and authenticated scanning
The tool parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution, cross-referencing spec definitions against runtime behavior to identify undefined security schemes or deprecated operations. Authenticated scanning supports Bearer, API key, Basic auth, and Cookie methods, gated by domain verification via DNS TXT records or HTTP well-known files. Only a defined allowlist of headers is forwarded to limit exposure during authenticated tests.
Operational characteristics and integrations
Scans complete in under a minute using read-only methods, with no destructive payloads sent. Private IPs, localhost, and cloud metadata endpoints are blocked at multiple layers. Results are surfaced through a web dashboard with score trends and downloadable compliance PDFs, via a CLI with JSON or text output, and through a GitHub Action that can fail CI/CD builds based on a configurable score threshold. An MCP server enables scanning from AI coding assistants, and Pro tier adds scheduled rescans, diff detection, email alerts, signed webhooks, and Slack or Teams notifications.
Limitations and responsible use
The scanner does not fix, patch, or block findings; it provides prioritized findings with remediation guidance. It does not execute active SQL injection or command injection tests, detect business logic vulnerabilities, or perform blind SSRF validation that requires out-of-band infrastructure. It is not a replacement for human penetration testing for high-stakes audits. Use this tool as part of a layered security strategy and continuous monitoring program.
