Cybersecurity for the traveling principal
Your strongest controls protect the office. The family rarely sits inside it — and travel is where the protections thin out and the targeting sharpens.
Most security programs are built around the office network and the firm's devices. But principals and their families live, spend, and travel well outside that perimeter — on personal phones, hotel Wi-Fi, and social media that quietly broadcasts their location and routine. It's the highest-risk, least-covered surface in private wealth. Here's how to close the easy gaps.
Before the trip
Lock down the devices that travel
- Strong device passcodes and biometrics on every phone, tablet, and laptop that leaves home — and full-disk encryption (on by default on current iPhones and modern laptops; confirm it).
- Turn on the platform's heightened protection for high-risk users (for example, Apple's Lockdown Mode or Google's Advanced Protection) for principals who are plausible targets.
- Remove apps and accounts that don't need to travel; the smaller the footprint, the smaller the exposure.
- Enable remote-wipe and "find my device" so a lost or stolen device is a non-event, not a breach.
Quiet the signal
- Don't post travel in real time. "We're in Aspen this week" tells an attacker the principal is reachable, distracted, and far from the office — perfect conditions for an impersonation call.
- Review what family members and household staff post, too; the leak is rarely the principal.
During the trip
- Treat all public Wi-Fi as hostile. Use a trusted VPN, or better, the phone's own cellular hotspot. Hotel and airport networks are easy to impersonate.
- Never charge from unknown USB ports. Use your own charger and a wall outlet, or a charge-only "data blocker." Public USB can carry more than power.
- Beware shoulder-surfing and "evil maid" access. Don't leave devices unattended in rooms; use the safe; assume screens in public are being read.
- Expect the impersonation attempt. Travel is exactly when fraudulent "urgent wire" requests arrive, because the principal is hard to reach. The office should hold the line on verification — see our briefs on wire fraud and deepfake voice fraud.
Agree before departure: any money movement requested while the principal is away still requires the standard out-of-band callback and code-phrase. "They're traveling and said it's urgent" is the script of the scam — not a reason to skip the check.
The people around the principal
Household staff, family members, and personal assistants often have access to schedules, devices, and even payment authority — with none of the firm's training. They are routinely the softest entry point. A short, plain-language briefing for everyone in the principal's orbit does more than another piece of software.
A pocket checklist
- Devices encrypted, passcoded, remote-wipe on.
- High-risk protection mode enabled for principals.
- VPN or cellular hotspot — never open Wi-Fi.
- Own charger only; no public USB.
- No real-time location posting.
- Verification rules hold while away — no exceptions for urgency.
- Family and staff briefed before departure.
