CrowdStrike (NASDAQ: CRWD) on Tuesday announced plans to acquire browser security startup Seraphic Security for roughly $420 million.
Seraphic’s technology promises protection from zero-day browser exploits, phishing, and other browser-based attacks, all without requiring separate secure browsers or rerouting traffic.
News of the move to acquire Seraphic comes less than a week after CrowdStrike announced an agreement to acquire identity security startup SGNL for $740 million.
Seraphic’s integration with Falcon and SGNL
CrowdStrike says acquisition of Seraphic will allow it to extend zero-trust protections to the browser and fuse Seraphic’s continuous in-session browser protection with SGNL’s continuous identity to secure every interaction from the endpoint to the browser to the cloud.
“CrowdStrike will integrate Seraphic’s browser-native protection with the Falcon platform’s vast endpoint telemetry and SGNL’s continuous authorization technology, to deliver a unified next-gen identity security strategy,” the company explained. “Whether someone is working on a corporate laptop at company headquarters, or a contractor smartphone across the world, organizations will be able to provide secure access to corporate resources through their preferred browser”
“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.
Acquisition terms
The acquisition of Seraphic is expected to close during Q1 of CrowdStrike’s fiscal year 2027, with the $420 million purchase price to be paid predominantly in cash. A portion will be delivered in the form of stock subject to vesting conditions, CrowdStrike said.
Other firms competing in the enterprise browser security space include Surf, SlashNext (acquired by Varonis), Menlo Security, LayerX and Red Access.
