CrowdStrike (CRWD) has announced the acquisition of Seraphic Security, a startup specializing in browser runtime security, marking the company’s second major purchase in a week aimed at strengthening its cybersecurity offerings. While the terms were not officially disclosed, reports indicate that the deal is valued at $420 million, with most of the payment in cash and a portion delivered as stock subject to vesting conditions. The acquisition will see Seraphic’s browser-native protection integrated into CrowdStrike’s Falcon agentic security platform, enhancing its ability to secure enterprise browser sessions and user interactions.
This follows last week’s announcement that CrowdStrike had signed a definitive agreement to acquire SGNL, an identity security startup based in Palo Alto, California, for $740 million. SGNL specializes in continuous identity, a method that constantly verifies a user’s identity and access privileges in real-time using contextual signals such as location, device type, and behavior. Both deals are scheduled to close in the first quarter of CrowdStrike’s fiscal year 2027, pending regulatory approval and customary closing conditions. With these acquisitions, CrowdStrike is positioning itself to deliver a more integrated security solution across endpoints, browser sessions, and cloud applications.
Founder and CEO George Kurtz highlighted that Seraphic and SGNL will support CrowdStrike’s broader vision for Zero Standing Privilege, a security approach designed to dynamically control access across enterprise environments. He noted that decoupling security from the browser enables organizations to convert any browser into a secure enterprise tool without disrupting workflows or slowing productivity. The Falcon platform will leverage Seraphic’s in-session visibility along with SGNL’s adaptive authorization to deliver a more comprehensive identity and session protection model. Kurtz also emphasized that these acquisitions are aligned with CrowdStrike’s focus on increasing security around the growing use of AI agents, which present new and unpredictable risks for enterprise systems.
Analysts have viewed the acquisitions as strategically important for CrowdStrike. BTIG, led by Gray Powell, reiterated its Buy rating on CRWD shares, noting that the company is well-positioned to capture rising identity-related spending as organizations increasingly deploy AI technologies. Powell pointed out that securing identity in AI-enabled environments is becoming a top priority in 2026, and CrowdStrike’s expanded capabilities with SGNL and Seraphic position it to meet this demand. The acquisitions reflect CrowdStrike’s broader strategy to integrate identity verification, browser protection, and endpoint security into a single framework, providing organizations with a more unified approach to mitigating modern cybersecurity threats.
