ST Hälytys Oy was founded in 1992, and right from the start, the firm established a strong reputation as a leading security provider in the capital city region, with a competitive offering of design, installation, and commissioning as well as maintenance and service of fire alarms, emergency lighting, burglar alarms, CCTV, access systems, and door intercoms. The company drives sales by focusing on service and the aftersales market.

After many years of fruitful cooperation, ST Hälytys Oy enjoys recurring assignments from a loyal customer base consisting primarily of infrastructure and other public-sector organisations, private companies, construction firms, property owners/administrators, and retailers.

During 2022, ST Hälytys Oy’s turnover amounted to EUR 2.8 million, generated by business throughout the Helsinki region. The company has 12 employees working from the office in Vanda.

“As part of Prosero, we’ll be able to benefit from the group’s strong financial standing and the purchasing advantages offered by such a large group. This will give us a significant competitive edge while enabling more successful procurement processes. Joining Prosero allows us to maintain the flexibility of a smaller company, and at the same time we can enjoy the advantages of being part of a larger group,” says Risto Tonteri, CEO for ST Hälytys.

“ST Hälytys represents an important move for Prosero in the Helsinki region and Finland as a whole. We’ve already seen examples of the firm’s exceptional service-mindedness and professionalism. They will be an asset for the group. We’re very happy that ST Hälytys Oy has chosen to become part of Prosero,” says Jyri Aho, Country Manager for Prosero.
