With deep roots in Nordic telecommunications and security, Addsecure has been at the forefront of developing cloud-based solutions for secure critical communications since the early 2000s. The company was also the first in Scandinavia to receive bank approval for mobile-based alarm solutions.

In May 2025, Addsecure expanded its capabilities through the strategic acquisition of Grouptalk, a European leader in cloud-based push-to-talk (PTT) solutions. Grouptalk’s platform enables mobile workforces to collaborate in real time through instant group communication and serves major clients including SAS, Securitas, and Volvo.

“Addsecure is redefining how teams stay connected in life- and business-critical environments. With our expertise and technologies, we can deliver secure, reliable and innovative communications solutions that strengthen operational efficiency, drive growth, and create greater value for customers across Europe”, says Wim Harthoorn, Director of International Sales, Smart Alarms, at Addsecure.

Addsecure will present its certified fire alarm signalling portfolio, featuring:

• Iris-4: A robust alarm transmission system with intelligent redundancy.

• DALM: A flexible IP/4G transmission solution designed for rapid deployment and easy maintenance.

• Live demonstrations will be conducted, offering insights into migration strategies and best practices to ensure compliance, maximize uptime, and reduce lifecycle costs.

As well as its cloud-based push-to-talk solutions:

• Grouptalk App: Transforms Android and IOS smartphones into powerful two-way radios, enabling instant communication via Push-to-Talk over Cellular (PoC).

• PC Dispatch: A command-and-control solution featuring multi-team push-to-talk, emergency alarms with listen-in capabilities, text messaging, queue management, GPS positioning, private calls, full-duplex voice, and live video streaming.

• PoC radios and PTT accessories compatible with smartphones and PC Dispatch.

At the event, visitors to the Addsecure stand will be able to view video presentations illustrating real-life applications of the push-to-talk solutions.
