Push Security

About the Company

Push Security is the most advanced security tool in the browser, delivering real-time detection and response where today’s work (and attacks) actually happen.

Push gives defenders visibility into user activity, attacker behavior, and browser-level risk. It detects threats like phishing, session hijacking, ClickFix-style attacks, and malicious browser extensions; enforces secure login practices like MFA and SSO; and provides the telemetry teams need to investigate fast.

Built on continuous research and offensive testing, Push sees what attackers see, and stops them in their tracks. That’s why leading security teams trust Push to bring visibility and control to one of the most critical blind spots in the enterprise.
