CrowdStrike To Acquire Seraphic Security For Secure Browser Push

It’s the second acquisition for the cybersecurity giant announced in just the past week and aims to bring capabilities for boosting security directly within web browsers.

CrowdStrike announced Tuesday that it plans to acquire Seraphic Security, a startup with technologies for securing enterprise browser usage.

It’s the second acquisition deal for the cybersecurity giant announced in just the past week, following the disclosure Thursday that CrowdStrike had reached a $740 million agreement to acquire identity protection startup SGNL.

The price tag for the Seraphic deal, which was not revealed Tuesday, will be “predominantly” paid in cash, according to a news release. The deal is expected to be completed during the first quarter of the vendor’s fiscal year, which closes April 30.

CrowdStrike’s Falcon Fund had been among the previous investors in the startup.

In its news release Tuesday, CrowdStrike said the acquisition of Seraphic aims to bring capabilities for boosting security directly within web browsers to its Falcon platform.

Founded in 2020, Seraphic offers secure enterprise browser technologies delivered via a simplified architecture and reduced cost, according to the company.

Seraphic’s capabilities—including secure web gateway, zero-trust network access and cloud access security browser—also can provide secure access to SaaS-based and private web applications, the startup has said.

Named by CRN as one of the hottest cybersecurity startups of 2025, Seraphic announced raising $29 million in Series A funding led by GreatPoint Ventures, with participating investors that included the CrowdStrike Falcon Fund, in January 2025. The startup debuted its new BrowserTotal service in June 2025, which aims to enable real-time assessment of an enterprise’s browser security posture.

CrowdStrike said in its release Tuesday that it plans to combine Seraphic’s “continuous in-session browser protection” with identity protection and authorization capabilities from SGNL as well as with the Falcon platform’s endpoint telemetry and threat intelligence.

The combination will ultimately provide next-generation identity security that “protects every interaction” across endpoints, browser sessions and the cloud, according to CrowdStrike.

The deal is also the fourth acquisition announced by CrowdStrike since August. That month, CrowdStrike announced it had reached a $290 million deal to acquire a startup that provides data pipeline management, Onum.

Then in September, CrowdStrike announced a $260 million agreement to acquire Pangea, a startup that offers guardrails for GenAI-powered applications.
