Black-box scanning for constrained IoT environments
For many IoT and OT deployments, intrusive instrumentation is not feasible. This scanner operates as a black-box service that only requires a reachable URL. It uses read-only methods (GET and HEAD) plus text-only POST for LLM probes, avoiding any agents, SDKs, or code access. Scan completion is typically under a minute, which suits environments with limited maintenance windows.
Detection coverage aligned to industry frameworks
The scanner evaluates findings against three primary frameworks by mapping results directly to their controls: PCI-DSS 4.0, SOC 2 Type II, and OWASP API Top 10 (2023). Detection categories include authentication bypass, JWT misconfigurations, broken object level authorization, insecure direct object references, privilege escalation, input validation issues, rate limiting anomalies, data exposure such as PII and API keys, encryption misconfigurations, SSRF indicators, inventory and versioning gaps, unsafe consumption surfaces, and LLM/AI security probes across tiered scan depths.
OpenAPI contract validation to reduce false positives
Where an OpenAPI definition is available, the scanner parses OpenAPI 3.0, 3.1, and Swagger 2.0 with recursive $ref resolution. It cross-references spec definitions against runtime observations to highlight undefined security schemes, sensitive fields, deprecated operations, and missing pagination. This helps align expected behavior with actual service implementation, which is valuable when assessing IoT backends that expose HTTP APIs.
Authenticated scanning and strict header controls
For endpoints that require authentication, support is provided for Bearer tokens, API keys, Basic auth, and Cookies at the Starter tier and above. Domain verification is enforced through a DNS TXT record or an HTTP well-known file to ensure only the domain owner can scan with credentials. Forwarded headers are limited to Authorization, X-API-Key, Cookie, and X-Custom-* to reduce unintended exposure of internal headers.
Limitations and responsible use guidance
The tool does not perform active SQL injection or command injection testing, as those methods fall outside its read-only scope. It does not detect business logic vulnerabilities, blind SSRF relying on out-of-band infrastructure, or guarantee findings that would satisfy an auditor. It does not replace a human pentester for high-stakes assessments, and remediation guidance is provided to help teams investigate findings rather than to automate fixes.
