How Tempest Security scaled field communication from radios to PoC

Being able to quickly and securely scale internal group communication is critical for the security industry today. Tempest Security achieved that by moving from traditional radios to GroupTalk’s PoC solution (push-to-talk over cellular) that works over 4G/5G or WiFi — enabling instant communication and flexible team coordination in the field worldwide.

Tempest Security is a leading Swedish security company specializing in guarding services, risk management, and technical security solutions. With GroupTalk, they can now scale communication from a few guards to full teams across multiple sites. Real-time PTT (push-to-talk), personal alarms, location tracking, and rapid channel creation allow teams to respond to the right person, work safer, and maintain full operational control — even during 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," says Fredrik Herodes - Team Leader, Tempest Security.

From radios to PoC for instant coordination

Before GroupTalk, Tempest Security relied on traditional radios that offered limited range, inflexible channel structures, and slow reconfiguration whenever needs changed. By moving to the cloud-based GroupTalk app for push-to-talk, their teams have gained a far more agile communication workflow. Today, new talk groups can be deployed in minutes, staffing can be adapted on the fly, and guards and supervisors enjoy consistently clear audio regardless of location.

Previously, operations depended on fixed radio channels that demanded hands-on technical adjustments. With GroupTalk, Tempest Security can instead tailor communication spaces instantly — from dedicated channels for high-profile clients to temporary setups for events or short-term increases in personnel.

Lone workers are also better protected thanks to built-in personal alarms and GPS positioning, ensuring that assistance is always available with a single press when incidents arise.

"Collaboration with GroupTalk is very smooth. They are very personal in their communication with us, and we have dedicated contacts at GroupTalk. We usually receive support the same day, and we are very satisfied with our business-to-business," says Fredrik Herodes - Team Leader, Tempest Security.

Why this matters for security operations

In the security industry, response time and coordination are everything. A single delayed message or unclear instruction can be the difference between a contained incident and a critical escalation. With GroupTalk, security teams gain real-time communication tools that keep every guard, supervisor, and coordinator aligned — even when situations shift quickly.

Imagine a busy evening at a shopping mall. A shoplifting attempt turns into a chase, crowds move unpredictably, and supervisors must redirect guards instantly to secure exits and protect bystanders. With traditional radios, channels can be busy and messages may not reach the right person. Coverage is limited, and instructions can easily get lost in the noise.

With GroupTalk, supervisors can immediately create a dedicated incident channel, dispatch the closest guards using live GPS positioning, and ensure everyone receives the same clear message at the same time. Lone workers can trigger alarms with a single press, giving the team instant visibility of their location.

This level of precision and responsiveness doesn’t just improve efficiency — it protects people, reduces risk, and ensures that operations run smoothly no matter the situation.
