Trailers, job sites, and field crews: how should we manage laptops and tablets?

A crew lead leaves a tablet on the tailgate at a job site and drives off. By the time anyone notices, it's gone, along with whatever was signed in on it. Whether that's a shrug or a scramble comes down almost entirely to how the device was set up before it went missing.

Between the office, the trailers, and the job sites, a construction company's computers and tablets spend most of their life outside any building you control. That's normal for the work, and it's exactly why field devices are where the real risk sits. Managing them isn't about locking crews down; it's about making sure a lost tablet or a stolen laptop is an inconvenience, not a breach.

The risks that come with mobility

Field devices get dropped, left in trucks, handed between crew members, and occasionally stolen off a site. They're often on cellular or job-site Wi-Fi instead of a managed network, so they can fall behind on updates. And personal use creeps in when a device isn't set up with a clear purpose. Each of those is manageable, but only if the devices are actually enrolled in a management system rather than bought at a big-box store and handed out.

What mobile device management (MDM) does

• Enrollment and policy: every device is known, configured the same way, and kept current over cellular, not just on the office network.
• Encryption: data on a lost device is unreadable without credentials.
• Remote wipe and lock: a missing tablet can be locked or erased before anyone gets into it.
• App management: dispatch and field-service apps are deployed and updated centrally.
• Separation of company and personal data on devices that do double duty.

Company devices vs. BYOD

Company-owned devices are simpler to manage and the right default for anything touching company data. If crews use personal phones for email or scheduling, those should still be enrolled in a way that protects company data without taking over the personal side. The goal is the same either way: you decide what happens to company data on a device, no matter where the device is.

The payoff shows up on the worst day. Read what happens when a superintendent loses a laptop with and without this in place.
