    What’s at risk and how we help

    Lone worker devices connect your people to help 24/7

    Employees who work alone often face risks without colleagues nearby to help. A fall, medical emergency or threatening situation can quickly become serious if support is difficult to reach.

    Lone worker devices provide a fast and reliable way to access assistance when needed. With SOS activation, GPS location tracking and Man Down detection, they help employees raise an alarm quickly and share accurate location information, supporting a faster response and greater reassurance for workers and employers.

    Flexible mobile protection for employees on the move

    The Securitas Personal Safety App helps protect employees working remotely, travelling or operating in higher-risk environments.

    Users can raise instant alerts and share location information with emergency contacts and a dedicated monitoring centre. Features include Journey Tracking, Check-Ins, Meeting Timers, Live Location Sharing and Man Down detection.

    Built-in incident reporting and privacy features support both employee wellbeing and organisational duty of care. Server-based monitoring helps ensure alerts can continue to be escalated, even if a device loses power.
