Prosero announces the acquisition of AS Brann og Sikringservice and Lås og Beslag AS, two prominent local players in the security industry in the Oslo region. Through these acquisitions, Prosero strengthens its position and expands its capacity to deliver high-quality security solutions in the region.

AS Brann og Sikringservice was founded in 1981 by Gunnar Fjellet and was followed by Lås og Beslag AS, founded in 1995. Today, the business is run by sons Odd Fjellet and Torbjørn Fjellet. Together, the businesses offer a comprehensive portfolio of security solutions, including access control, mechanical and electromechanical locking, door automation and intercom, as well as fire safety.

The customer base consists of public sector customers (hospitals and schools), as well as businesses, primarily property owners and managers.

In recent years, the businesses have shown impressive growth thanks to successful strategic and operational efforts and strong customer relationships. In 2022, the companies had a turnover of NOK 45 million. The 18 employees will continue to be based in the two offices in Porsgrunn and Skien.
