Push Security

Push Security is a London-based browser security vendor whose platform makes the web browser a control point for stopping identity-based attacks. The company sells its software-as-a-service platform to enterprise security teams across the United Kingdom and United States and through a global partner network, and was built by a team with offensive- and defensive-security backgrounds from firms including MWR InfoSecurity and Duo Security. Founded in 2020, Push has raised about $49 million to date, including a $30 million Series B in April 2025 led by Redpoint Ventures with backing from GV (Google Ventures), Datadog Ventures, and Decibel.
