Risk Scoring And Prioritization
Receive a letter-grade risk score from A to F for any public API endpoint with a standard HTTP interface. The scanner completes in under one minute using only read-only methods such as GET and HEAD, plus text-only POST for LLM probes. Each finding is prioritized so teams can address the highest-impact issues first, focusing effort on authentication bypass, IDOR, and data exposure rather than low-severity noise.
Coverage Against Standards
Findings map directly to PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). The scanner surfaces security misconfigurations such as JWT alg=none, missing security headers, and sensitive data in error responses, providing evidence that supports audit activities and validates applied controls. For other frameworks, it helps you prepare for and aligns with security controls described in relevant guidelines without claiming certification or compliance guarantees.
OpenAPI And Runtime Correlation
The scanner parses OpenAPI 3.0, 3.1, and Swagger 2.0 documents with recursive $ref resolution and cross-references spec definitions against runtime behavior. It flags undefined security schemes, sensitive fields exposed beyond defined scopes, deprecated operations, and missing pagination, reducing discrepancies between documented contracts and actual implementation.
Authenticated Scanning Controls
Authenticated scans support Bearer tokens, API keys, Basic auth, and cookies. Domain verification is enforced through DNS TXT records or an HTTP well-known file to ensure only the domain owner can submit credentials. A strict header allowlist forwards only Authorization, X-API-Key, Cookie, and X-Custom-* headers, preventing unintended leakage of internal tokens.
Detection Of LLM And Infrastructure Risks
The scanner includes an LLM security module with 18 adversarial probes across Quick, Standard, and Deep tiers, testing for system prompt extraction, instruction override, DAN and roleplay jailbreaks, data exfiltration, cost exploitation, and token smuggling. Input validation checks cover CORS wildcard usage, dangerous HTTP methods, debug endpoints, SSRF indicators, and unsafe consumption patterns such as excessive third-party callbacks.
