Browser-Native Security for the Modern Workforce

Push Security is a browser-native security platform that detects and stops identity attacks such as phishing, session hijacking, and credential theft in the browser, where employees now do most of their work.

It deploys as a lightweight extension on the browsers teams already use, and autonomous AI agents hunt across browser telemetry to feed its threat detection engine.

The platform also gives full visibility into AI use, from shadow AI discovery and activity inside AI tools to governance of AI agents' OAuth access and real-time AI usage policy.

Browser-layer data loss prevention blocks file uploads and downloads, tracks clipboard activity with pattern matching, and categorizes and blocks domains.

Founded in 2021, Push Security raised a $30 million Series B in April 2025 led by Redpoint Ventures.
