2023/07/18

Prosero continues its expansion in Denmark through the acquisition of Nielsen Sikring, with headquarters in Fredrikshamn. Nielsen Sikring is integrated in ACTAS A/S, a nationwide Danish security company that has been part of Prosero since 2019.

Founded in 2010 by Søren Nielsen, Nielsen Sikring serves many large and national customers with a complete range of security solutions, including alarms, access systems, and camera surveillance. Through professional craftsmanship, a focus on quality, and a high level of service, Nielsen Sikring has succeeded in building a loyal customer base. This has in turn created impressive growth for the company. Last year, turnover amounted to almost DKK 10 million.

Nielsen Sikring’s four employees are specialists in their fields and serve customers throughout Denmark.

“It gives me great pleasure to know that we’ve been able to strengthen Nielsen Sikring’s opportunities for growth by cooperating with Prosero and ACTAS,” says Søren Nielsen. “The agreement to join Prosero ensures that we’ll have the necessary resources and expertise to meet our customers’ requirements and the ever-increasing demand we’re seeing in the market. We also look forward to continuing and developing our close cooperation with our return customers.”

“Nielsen Sikring is a well-run security company with a recognized high level of service, and this is ideal for Prosero,” says Jørgen Kronborg of Prosero Denmark. “I’m convinced that both the employees and customers will be well integrated in ACTAS. Together, we’re sure to achieve great things in the future.”


Prosero is northern Europe’s leading supplier of technical security solutions, with years of experience and a strong local presence in more than 130 locations in Sweden, Norway, Denmark, and Finland.

Prosero is made up of local leaders in security in a network that unites the local presence and flexibility of smaller companies with a larger company’s stability and digital expertise. Prosero delivers competence and provides cutting-edge security technology tailored to each customer’s needs and applications. Its service offering includes consulting, integration, operations, maintenance, service, and monitoring of alarms, access control, camera systems, locks, and fire safety. Its total turnover amounts to more than SEK 3.5 billion.
