Protrix Guard
Read full descriptionHide full description
Protrix Guard is the field companion for security guards executing escort logistics missions on the Protrix platform. Built for the road, it keeps your assigned missions, status flow, and evidence in one place — and keeps working when the signal drops. Key features: - Mission details at a glance — pick-up point, drop-off point, and customer notes. - One-tap status flow — Departed → At PUP → In Transit → At DOP → Completed → Returned. - Stop logging with location, reason, and duration. - Photo capture and receipt evidence for tolls, parking, ferries, and tunnels. - Hours and kilometre logging per mission. - Mission-scoped secure messaging with your dispatcher. - Push notifications for new assignments, updates, and check-in reminders. - Route recording while you escort — your operations centre sees where the transport has reached, even when your phone is locked or the app is closed. It runs between pickup and drop-off only, shows an ongoing indicator the whole time, and stops on arrival. - Offline-first: status updates, stop logs, photo evidence, expenses and messages are saved securely on your phone and sync automatically when you reconnect. Continuous route recording needs a live connection, so a long coverage gap leaves a gap in the trail. Protrix Guard requires a Protrix account with the Security Guard role. It is a B2B tool for accredited security operators and is not intended for general consumer use.
