API Security

APIs are your largest
attack surface

REST, GraphQL, WebSocket, gRPC — each protocol has its own attack surface. MANTIS Agent tests every protocol with purpose-built detection. Schema-aware. Auth-aware.

Purpose-built for every protocol

Each protocol gets its own detection engine, payload library, and analysis pipeline.

REST

  • IDOR with multi-role differential
  • Mass assignment
  • JWT manipulation
  • Rate limiting bypass
  • Business logic flaws

GraphQL

  • Introspection & disabled introspection bypass
  • Field suggestion extraction
  • Alias & directive overloading
  • Batch brute force
  • Mutation IDOR

WebSocket

  • Cross-site WebSocket hijacking
  • Auth bypass on upgrade
  • Message injection
  • Protocol downgrade
  • Origin validation bypass

gRPC

  • Server reflection enumeration
  • Auth bypass on unary calls
  • Payload injection
  • Plaintext interception
  • Large message overflow

Auth-aware by default

MANTIS tests with multiple authentication profiles simultaneously. Multi-role IDOR testing compares responses across unauthenticated, low-privilege, and high-privilege sessions with double verification to eliminate false positives.

Secure APIs from both sides

MANTIS Agent tests your APIs offensively — finding IDOR, injection, and auth bypass. MANTIS Control monitors the infrastructure those APIs run on, catching misconfigurations and drift.
