Vendor

WithSecure is the half of F-Secure that kept the business customers. The original company was founded in Helsinki in 1988 as Data Fellows by Petri Allas and Risto Siilasmaa, became F-Secure, and in 2022 split in two: consumer products stayed with F-Secure, and everything sold to organisations became WithSecure. They are now separate companies with a shared history, and both appear in this index. Its products are gathered under WithSecure Elements, one cloud platform with modules for Endpoint Protection, Endpoint Detection and Response, Exposure Management and Collaboration Protection, sold largely through a partner network rather than direct. WithSecure Countercept is the managed detection and response service above it, run by the company's own analysts. It sells mainly into Europe and Japan and leans on that in its compliance positioning — GDPR and NIS2 alignment, ISO 27001, ISAE 3000 and SOC 2 Type II. The practical consequence of the 2022 split, for anyone reading older reviews, is that a test result published under the F-Secure name may describe a product now sold by this company, or by the other one.
