Tempest security staff using rsm for push to talk and personal alarm in grouptalk app

From radios to cloud Push-to-Talk

Being able to quickly and securely scale internal communication is critical in the security industry. Tempest Security achieved this by moving from traditional radios to GroupTalk’s cloud-based PTT (Push-to-Talk) solution, enabling instant communication and flexible coordination in the field.

Tempest Security, a leading Swedish security company specializing in guarding services, risk management, and technical security solutions, can now scale communication from a few guards to full teams across multiple sites. Real-time PTT, personal alarms, location tracking, and rapid channel creation allow teams to respond to the right person, work safer, and maintain full operational control—even in high-pressure situations.

"GroupTalk has allowed us to scale quickly—from two people communicating to teams of 20–30 guards speaking together. The platform makes it easy to manage our personnel in high-pressure situations, and adding new users on the fly takes just a few minutes in the admin. It gives us the flexibility to adjust operations to the needs of our business."

Real-time coordination for security staff

Before GroupTalk, Tempest Security relied on traditional radios with limited range and inflexible channels. By moving to the cloud-based GroupTalk app, teams gained agile communication: new talk groups can be created in minutes, staffing adapted instantly, and audio remains clear regardless of location.

Lone workers are better protected with built-in personal alarms and GPS positioning, ensuring immediate assistance when needed. Supervisors can dispatch the closest guards using live GPS and create dedicated channels for incidents, events, or temporary staffing, keeping everyone aligned in real time.

Key Results:

  • Real-time group communication across guards and supervisors
  • Fast scaling from small teams to 30+ guards
  • Rapid creation of dedicated channels for events or high-risk tasks
  • Integrated personal alarms and GPS tracking
  • Easy administration and fast deployment

"Collaboration with GroupTalk is smooth, and we receive support the same day. We are very satisfied with our business-to-business relationship."
