Prosero acquires Suomen Turvalukko OY in Finland


Prosero continues its strong growth journey in Finland and, through the acquisition of Suomen Turvalukko, is breaking new ground in the eastern part of the country around Kuopio. The company offers products and solutions in locking and access control systems, intercoms, door automation, burglar alarms, and CCTV.

Suomen Turvalukko was originally founded in the 90s as a family-owned locksmith but got a fresh start in 2018 when second-generation entrepreneur Samu Sallinen took over the business. In connection with the new start-up, Jimi Väisänen joined the company and together the two entrepreneurs have further developed the company and in a short time built up a successful business with a strong range and a good reputation in the region. Since start-up, the company has shown strong growth based on a high level of service and good relations with the region’s construction and real estate companies, housing associations, industry, retail, and the public sector. Sales are primarily driven by service and aftermarket as well as a fast-growing e-commerce. During the last financial year, the company had a turnover of nearly EUR 2.4 million with 11 employees based in the offices in Kuopio (HQ) and Varkausand.

– “Suomen Turvalukko Oy is a young but rapidly growing player in the security sector. Our area of operation is North and South Savo,” says Jimi Väisänen, CEO of Suomen Turvalukko OY. “We operate primarily in the after sales services market and the cornerstone of our business has always been first-class service. The world is changing and at the same time our operating environment is evolving very rapidly, for example thanks to digitalization. We want to be a trendsetter in this development and strongly involved in the future. We see that this acquisition allows us to offer an even wider range of services and the opportunity to develop the company, so that we can continue to offer the industry’s best service to our customers.”

“With the acquisition of Suomen Turvalukko, we are expanding into a new growing geography, which complements and strengthens our existing business well,” says Sebastian Ryman, Head of M&A at Prosero Security Group. “We see great growth potential where they focus on an attractive market segment and have built up a successful organization with an entrepreneurial culture, which fits very well with Prosero.”
