Push Security runs a browser agent that observes identity activity on SaaS and web apps, detecting and blocking attacks such as adversary-in-the-middle phishing, credential stuffing and session theft.
It also surfaces identity posture issues such as shadow SaaS, weak or reused passwords and missing MFA. Push raised a $30M Series B in April 2025 led by Redpoint.
Innovation Matrix Assessment
Pioneered browser-level identity attack detection with frequent public research.
Gives teams visibility where identity attacks occur, in the browser.
$30M Series B (Apr 2025) led by Redpoint with GV and Datadog Ventures; $49M total.
Moves detection to the browser rather than the identity provider.
Public research on real phishing kits adds credibility; independent customer proof limited.
Browser as the primary work surface keeps this relevant.
Why CISOs Should Care
Identity attacks often bypass MFA at the browser; Push sees and stops them where they happen.
What Makes It Different
A lightweight browser agent provides detection that IdP and network logs miss.
