Helping Security
& Development Teams
The only API security platform that enforces governance and compliance from design to runtime and gives developers the tools to code security from inside the IDE

API Capture automates the generation of OpenAPI contracts and API security testing configurations from Postman collections and API traffic.

    • Free up development teams from time-consuming design and maintenance tasks
    • Automate security test cofigurations
    • Use OpenAPI specification to improve API documentation
    • Capture unknown traffic and reconcile OpenAPI definitions with real traffic to improve governance

API Audit provides instant security scoring for prioritization and remediation advice at design time and API Scan scans the API to ensure conformance to the OpenAPI contract and detect vulnerabilities at both testing time and runtime.
    • 300+ security checks
    • Actionable report with zero false positives
    • Available from IDEs and CI/CD pipelines
    • Instant visibility into API security status
    • Test live endpoints
    • Early identification of OWASP API Security Top 10 issues

API Protect offers runtime API security policy enforcement with a low footprint, containerized micro-API firewall.

    • API Protect is configured in one-click from the API contract
    • The API Contract becomes the white list for security
    • No need to guess via AI/ML which traffic is valid
    • No policies to write
