Port Øst joins Prosero Security Group


Port Øst AS is a Norwegian door specialist that offers tailormade solutions for doors, fire curtains, barriers, and gates used in a variety of industry and public-sector applications. The acquisition strengthens Prosero’s offer in access control.

Port Øst AS was founded in 2018 as a family-owned company by Thore Lerfaldet, the current CEO for the firm. With considerable industry experience, good business relationships with leading manufacturers, and a strong team, Port Øst has gained an excellent reputation and has built close partnerships with its customers. The company’s tailormade solutions for doors, fire curtains, barriers, gates, roller grilles, and garage doors can be found in many industrial facilities, car parks, and housing cooperatives throughout southeast Norway. With responsibility for everything from planning and installation to annual maintenance and service, Port Øst ensures the highest quality in these systems.

Today, Prosero maintains a broad portfolio of integrated systems to safely and efficiently manage access and flows related to buildings and other properties. With the growing interconnection and integration of systems, customer demand is increasing for the type of products and services offered by Port Øst. Therefore, the acquisition will create interesting opportunities and allow Prosero to deliver even better products, services, and total solutions.

In 2022, the company’s turnover amounted to NOK 35.5 million. The seven employees work from the head office in Solihøgda in Hole Municipality to serve all of south-eastern Norway.

– “We work continuously to remain at the forefront of our industry, in terms of both technology and service. This is one of the foundations of our impressive development,” says Thore Lerfaldet, CEO of Port Øst. “The security industry is experiencing rapid development. As part of Prosero, we’ll strengthen our position as we continue to shape our products and services. We can also contribute our unique expertise to the group, and we look forward to the exciting cooperation that will result.”

“Doors, barriers, garage doors, and gates are essential in protecting a property; they require careful adaptation to local conditions and specific use cases. Through the acquisition of Port Øst, we’re gaining a leading specialist in doors and related services, and this know-how will be valuable for the entire group,” says Andreas Setting, Country Manager for Prosero. “This segment is closely related to Prosero’s other service areas in access control, camera surveillance, control systems, and locks and fittings. We’re so pleased that Port Øst AS has joined the group.”
