Protect your APIs with enterprise-grade security that scales with your organization.
Trusted by teams at
Protect your sensitive data with robust, cloud-first API security
Catch vulnerabilities before they ship
Postman scans your API specs and collections for security risks like missing authentication, exposed secrets, and OWASP Top 10 violations so your team can find and fix issues during development.
Keep secrets out of shared environments
Real-time secret scanning detects leaked credentials and Postman Vault keeps sensitive values stored locally on each developer's machine so they're never synced to the cloud.
Enforce security standards across every API
Postman's centralized catalog and built-in governance rules validate that every API and service meets your organization's auth and data-handling requirements before reaching production.
