Lone worker app for security guards: what it should do, and what to ask

A lone worker app for security guards lets an officer who works a post alone raise an alarm in seconds, tells the office where the officer is, and makes sure someone takes charge of the alert. The best ones also keep a record of who responded and when, so a company can show a client or insurer what happened.

This guide lists what to look for, the questions to ask any vendor, and how Guardix handles each point. For the safety plan behind the app (risk assessment, post orders and check-in times), see lone worker safety for security guards.

Key points#

• An SOS alert must be quick to send and hard to send by mistake, and it must carry the officer's location and site.
• Someone has to own every alert: look for escalation when nobody responds.
• The response must leave a record: who took charge, who went to the scene, and how it ended.
• An app is only part of the plan: the officer still calls 911 in an immediate emergency.

What a lone worker app should do#

A fast SOS that is hard to trigger by accident#

The alert should take one deliberate action, such as a slide rather than a tap, so a phone in a pocket does not set it off. An officer who sends one by mistake should be able to cancel it, and the office should see that it was cancelled.

Location and site with every alert#

The alert should arrive with the officer's GPS position, the post site and the time, and the responder should be able to open the location on a map and call the officer from the alert.

Escalation when nobody answers#

An alert that nobody sees is no help. Look for an app that sends the alert again until someone takes charge, and shows the office how long the alert has gone without an owner.

Clear ownership and responders#

One person should own the alert, with the option to hand it over, send staff to the scene and track whether they are on the way or on scene.

A record of the response#

Every action should land on a timeline, and closing the alert should need a note on what happened. That record answers the client's and insurer's questions later.

Site-specific steps#

Different posts need different responses. A good app lets each site have its own steps and phone numbers, with a company default for the rest.

Questions to ask any vendor#

• How does the officer send an alert, and how do you prevent accidental alerts?
• Who receives the alert, on which devices, and can we choose by role?
• What happens if nobody responds within a few minutes?
• Does the app detect a fall or missed movement, or prompt the officer to check in at set times? If so, how is it set up per site?
• Does the app call emergency services itself, or must the officer or office call?
• What works without a mobile signal?
• Can we export the alert history?

How Guardix handles lone worker alerts#

Guardix SOS lets a clocked-in officer slide one control in the phone app to alert the office. The alert carries the officer's GPS position, post site and time, shows at once on the web SOS Alerts page and as a push on staff phones, and stays open until someone takes charge and completes it with a note.

• Owner and responders: the first person to acknowledge takes charge and can hand the alert over, send staff to the scene and track them as On the way, On scene or Released.
• Escalation: if nobody takes charge, Guardix sends the alert again to the people who can, and each repeat is written on the timeline.
• Site steps: each post site can have its own SOS steps with a phone number per step, or use the company default list.
• Record: every action is on the alert's timeline, closing it needs a completion note, and the SOS Alerts page exports to CSV.
• Mistakes: the officer can cancel an alert as Sent by mistake, and the office sees it apart from completed alerts.

Guardix does not call the police or any emergency service: the officer's phone tells them to call 911 directly for an immediate emergency. Between alerts, GPS tracking shows where clocked-in officers are, and guard tours show when each checkpoint was last reached, which helps a supervisor notice an officer who has gone quiet.

Frequently asked questions#

What is a lone worker app?#

A lone worker app is a phone app for people who work alone. It lets them raise an alarm quickly, shares their location with the people who respond, and records how each alert was handled. Security companies use one for officers on solo posts and night shifts.

Does a lone worker app replace calling 911?#

No. In an immediate emergency the officer should call 911. The app tells the security company that an officer needs help, where they are, and who is responding, and keeps a record of the response.

What should happen when nobody responds to an SOS alert?#

The app should send the alert again to everyone who can take charge, and keep doing so until someone acknowledges it. In Guardix the repeats stop as soon as someone takes charge, and each repeat is written on the alert's timeline.

What else does a lone worker safety plan need?#

A risk assessment of each solo post, post orders that say what to do in an emergency, set check-in times, and a plan for a missed check-in. See lone worker safety for security guards.
