CrowdStrike to acquire Seraphic Security, a specialist in browser runtime security, in a move aimed at embedding advanced protection directly into web browsers — a modern enterprise’s most critical attack surface. 

The deal, expected to close in CrowdStrike’s first fiscal quarter of 2027, will see the security giant pay predominantly in cash with a portion of the consideration in stock. Financial terms have not been officially disclosed by the company, though some reports value the transaction at approximately $420 million.

Why Browser Security Matters

Web browsers have become central to how organizations work — hosting SaaS apps, enabling communication, and serving as the workplace for AI-driven tools. Yet traditional security approaches often leave browsers as blind spots, forcing firms into limited enterprise browsers or slow, network-based protections.

Seraphic’s technology addresses that gap by providing continuous, in-session runtime protection inside any browser — including Chrome, Edge, Safari, Firefox, and AI-centric runtimes — on both managed and unmanaged devices. This allows enterprises to enforce security without forcing employees to switch browsers or slow workflows.

A “Secure Enterprise Browser” on Any Device

CrowdStrike intends to integrate Seraphic’s capabilities with its Falcon® platform’s endpoint telemetry and threat intelligence, as well as with technology from another recent acquisition, SGNL, focused on continuous identity authorization. Together, this creates a Unified Next-Gen Identity Security Fabric, spanning endpoints, browsers, and cloud services.

Key enhancements expected from the integration include:

• In-session zero trust enforcement — continuous validation of user and session risk rather than single authentication checkpoints. 
• AI-aware browser protection — safeguarding interactions with generative AI tools and preventing unauthorized data access or exfiltration. 
• Advanced web DLP (data loss prevention) — AI-driven detection and blocking of sensitive data copying, uploads, or screen captures.
• Defense against session-based threats — stopping phishing, session hijacking, and “man-in-the-browser” attacks in real time.

CrowdStrike To Acquire Seraphic Security: Strategic Fit For Growth

The Seraphic acquisition follows closely on the heels of CrowdStrike’s recently announced $740 million deal for SGNL, underscoring the company’s strategy to unify identity, endpoint, and now browser security into a seamless defense ecosystem.

This move adds to a series of acquisitions by CrowdStrike over the past year, including purchases in data pipeline management and guardrails for generative AI applications, reflecting a broader push to expand its security platform across emerging risk vectors.

CrowdStrike To Acquire Seraphic Security: Voices from the Deal

“The browser is where modern work happens,” said George Kurtz, CEO and founder of CrowdStrike, emphasizing the need to protect users in the environments where they spend most of their day. Seraphic co-founder Ilan Yeshua noted that joining forces with CrowdStrike will enable “platform-level protection at the most important execution layer in the enterprise.”

CrowdStrike To Acquire Seraphic Security: Looking Ahead

CrowdStrike plans to complete the Seraphic acquisition by the end of its fiscal first quarter, subject to customary closing conditions. Once finalized, the integration promises to redefine how enterprises secure browser-centric work, especially in hybrid and AI-driven workplaces where traditional models fall short.
