Consumer and enterprise cybersecurity platform protecting 30M users globally

Computer and Network Security Helsinki 501–1,000 employees Founded 1988 Public Company

F-Secure operates a three-decade-old consumer and business security platform spanning endpoint protection, threat intelligence, and identity safeguards distributed through ~200 service provider partners. The tech stack reveals a cloud-native architecture (Python, Go, AWS, Docker, Kubernetes) paired with ML infrastructure (PyTorch, Databricks) and cross-platform client work (iOS, Android, macOS), while active projects center on scam detection at scale and serverless microservices—indicating a shift from monolithic endpoint products toward API-driven, cloud-delivered security services. Hiring is heavily weighted toward senior engineers (17 of 31 open roles), concentrated in core engineering, suggesting they're scaling detection and platform stability rather than expanding sales.
