CrowdStrike has announced a definitive agreement to acquire Seraphic Security, a leader in browser runtime protection, aiming to redefine enterprise security in the era of AI-driven work. As web browsers have become central to productivity, communication, and application execution, securing them has become critical. By integrating Seraphic’s browser-native security into the Falcon platform, CrowdStrike extends its protection beyond endpoints into the browser layer, safeguarding both human and AI-driven workflows.

This acquisition enables CrowdStrike to offer a unified Next-Gen Identity Security strategy by combining Seraphic’s browser protection, Falcon’s extensive endpoint telemetry, threat intelligence, and SGNL’s continuous authorization technology. Consequently, every interaction from endpoint to browser session to cloud will be secured under a seamless security fabric.

“Productivity requires flexibility and security; users want to work in their browser of choice. Seraphic delivers exactly that,” said George Kurtz, CEO and founder of CrowdStrike. “By decoupling security from the browser itself, we can turn any browser into a secure enterprise browser, without forcing change or slowing productivity. With our vast endpoint signals combined with Seraphic’s in-session visibility and SGNL’s dynamic authorization, we are defining the future of Zero Standing Privilege for the modern agentic workforce.”

The web browser has long represented a critical cybersecurity blind spot, despite employees spending roughly 85% of their workday there. Traditional security solutions often force users into controlled enterprise browsers or rely on high-latency network routing, limiting flexibility and visibility. Seraphic disrupts this approach by enforcing security directly within any browser runtime, including Chrome, Edge, Safari, Firefox, and agentic browsers, across both managed and unmanaged devices.

By correlating trillions of endpoint signals with deep, in-session browser telemetry, the Falcon platform can now interpret user intent, application context, and data flow in real time. Coupled with SGNL’s continuous authorization, access becomes dynamic, automatically granting or revoking permissions per session and per risk signal, preventing attacks before they can cause harm.

Key benefits of this integration for AI-driven enterprises include:

  • Enterprise AI Protection at the Browser Layer: Safeguard access to generative AI applications and agents while preventing unauthorized data exfiltration.
  • In-Session Zero Trust Enforcement: Apply continuous, identity-driven verification across all browser activity.
  • Next-Gen Web DLP: Stop data leaks through AI-based content filtering and granular execution-layer controls.
  • Session-Based Threat Prevention: Block session hijacking, phishing, and man-in-the-browser attacks at runtime.
  • Agentless Security for BYOD and Contractors: Protect browser sessions without requiring full endpoint agents.

“The browser is where modern work happens,” said Ilan Yeshua, CEO and co-founder of Seraphic. “In joining CrowdStrike, we are bringing platform-level protection to the most important execution layer in the enterprise, ensuring that zero trust is a continuous reality, not just a gateway check.”

By combining Seraphic’s runtime protection with Falcon’s endpoint intelligence, CrowdStrike strengthens its mission to secure modern workspaces, delivering real-time, continuous security from endpoints to browsers and beyond. This acquisition underscores the company’s commitment to proactive, flexible, and AI-ready cybersecurity.
