Discover APIs Wherever They Run

Eliminate blind spots
Auto-discover managed, unmanaged, and shadow APIs across clouds and containers.
Accuracy at the speed of cloud
Continuously track new deployments and configuration drift.
Expose risky surfaces instantly
Quickly identify externally exposed or high-impact APIs.

Support Any API Protocol

Secure every style
Protect REST, GraphQL, gRPC, SOAP, and legacy protocols with unified controls.
Automate catalog creation
Keep API documentation aligned with reality — not assumptions.
Enforce consistent rules anywhere
Apply policy across diverse architectures without friction.

Dynamically Catalog API Schemas

Live, runtime-based schema mapping
See actual API structures, not stale code comments.
Catch breaking changes fast
Detect drift and misalignment that introduce vulnerabilities.
Understand real data flows
Reveal dependencies and service-to-service interactions.

Classify Sensitive Data in Motion

Track regulated data everywhere
Identify PII, PHI, PCI, and secrets flowing through APIs.
Prevent accidental exposure
Spot when sensitive data crosses unsafe boundaries.
Strengthen compliance continuously
Reduce audit risk with accurate data handling visibility.

Detect & Stop API Threats

Find malicious behavior in real time
Spot abuse patterns like brute force, lateral movement, and token misuse.
Block threats before they escalate
Automated containment stops attackers mid-path.
Adapt to new attack vectors
API security evolves as adversaries and services evolve.

Test APIs with DAST for Vulnerabilities

Validate APIs in runtime
Catch issues attackers can actually exploit — not theoretical scans.
Surface broken auth and exposure risks
Ensure APIs enforce proper identity and access controls.
Fix confidently and quickly
Verify remediation and reduce exposure windows automatically.
