Push Security sells a browser extension that watches where employees sign in to SaaS, catching phishing and session hijacking that endpoint and identity tools miss. Its traction is real: 1.5 million endpoints, 380 percent growth around the 2025 Series B, and named references including GitLab and PortSwigger. A funded rival could obtain much of what sets it apart, since its open-source SaaS attack matrix is public and its SOC 2 and ISO certifications clear procurement without locking a buyer in. What lasts is the IdP and SIEM wiring a team builds around it, friction the record does not quantify. Push is exposed at the browser layer, where browser makers and identity platforms it overlays can ship the same telemetry.
