Live: Zero Trust, Wearables and the Future of Field Operations (2026) — A Playbook for Power Suppliers

Hook: Your field engineer is now a node on the network — secure them or risk service failures.

Wearables and connected devices accelerate diagnostics, but they also expand the attack surface. This is a practical playbook combining device selection, process and incident readiness for 2026.

Why wearables matter to power suppliers

Wearables provide hands‑free alerts, environmental sensing and rapid escalation. When combined with remote telemetry, they reduce truck rolls and improve safety.

“Integrated wearables give you data from the person at the cabinet — and a new place to secure.”

Selection criteria for 2026

• Battery life that easily covers a shift.
• Secure pairing and device attestation (part of a zero‑trust model).
• Environmental resilience (dust, heat, moisture).

Follow the hands‑on toolkit for field engineers in the zero‑trust domain at anyconnect.uk for specific device hardening steps.

Operational integration

1. Connect wearables to ticketing and asset data so alerts create pre‑filled incident reports.
2. Use mobile OCR and compact tablets to attach photos and serials to tickets — use devices recommended in docscan.cloud.
3. Train staff on secure pairing and lost device procedures.

Incident response and firmware risks

Wearables, tablets and edge controllers add firmware attack vectors; integrate device audits in your incident response playbook. The Incident Response Playbook at reliably.live pairs well with these practices.

Privacy and policy

Establish clear data governance. Wearables should only collect what’s necessary for safety and troubleshooting. Align policies with traveller wearables rules in hospitality and travel contexts described at bookers.site.

Training and human factors

Be deliberate: short, scenario‑based training and firmware rollouts reduce errors. We recommend monthly micro‑sessions and a simple checklist for pairing, charging and emergency stops.

Quick technical checklist

• Device attestation and certificate renewal schedule.
• OTA signed firmware only.
• Lost device wipe and remote disable.
• Telemetry throttling for low bandwidth conditions.

Where to start

1. Run a 6‑week pilot with a single depot and small wearable fleet.
2. Integrate ticketing and telemetry to produce auto‑filled incident reports.
3. Draft a data retention and privacy statement and publish it to customers.
