WithSecure

WithSecure, formerly known as F-Secure Business, is a leading European cybersecurity company headquartered in Helsinki, Finland, providing comprehensive penetration testing and security consulting services alongside their enterprise protection products. The company traces its roots back to 1988 when it was founded as one of the first antivirus companies in the world, and it demerged from F-Secure in 2022 to focus exclusively on corporate and enterprise security.

WithSecure's consulting division brings decades of experience to penetration testing engagements, with particular strength in European regulatory requirements including GDPR, NIS 2, DORA, and TIBER-EU. Their services include web application testing, network penetration testing, red teaming, cloud security assessments, and IoT testing. WithSecure's Countercept managed detection and response service works in tandem with their offensive testing, providing clients with both the attacker and defender perspectives.

The company serves a strong roster of European enterprise clients across financial services, manufacturing, and government sectors. Their team includes CREST-certified and OSCP-qualified professionals who follow methodologies aligned with OWASP, CREST, and TIBER-EU frameworks. WithSecure maintains offices across Europe and has recently expanded its presence in North America and Asia-Pacific.
