Change in the Leadership Team of F-Secure Corporation

TL Viswanathan, Chief Product Officer and a member of F-Secure Leadership Team, has decided to leave the company to pursue new career opportunities outside the company. TL will continue working at F-Secure until mid-August 2026 to ensure a smooth handover. Katja Kuusikumpu, Director, Portfolio Governance & Operations at F-Secure, will step into the role of interim Chief Product Officer effective 17 August 2026, and will lead the Product function through the interim period.

“I want to sincerely thank TL for his outstanding contributions to F-Secure over the past years. TL has played a central role in setting up our Embedded Security business as well as the Lookout Life acquisition and integration. From that foundation, he shaped the Product organization from the ground up; its overall level of aspiration, product vision, and commitment to consumer experience. The result is a world-class product team that we can all be proud of.” says F-Secure President & CEO Timo Laaksonen.

"My four years at F-Secure have been some of the most meaningful of my career. I leave with enormous pride in what we have accomplished and full confidence in the mission, the strategy, and the people executing it. I am grateful for the opportunity F-Secure has given me, and I look forward to what this team will achieve next." says TL Viswanathan.
