Overview
Working with sensitive data while away from the office increases the risk of accidental exposure or interception. This guide summarizes practical, low-cost steps you and your staff can use to reduce that risk when you must work in public places such as airports, cafes, or transit hubs.
These recommendations focus on protecting data confidentiality, avoiding persistent account access, and limiting exposure on unsecured networks and devices.
Key takeaways
- Prefer secure, private networks and avoid handling sensitive transactions on open Wi‑Fi.
- Use physical and technical controls—privacy screens, strong device locks, and encryption—when working in public.
- Avoid public or shared computers for private tasks and sign out of accounts when finished.
How it works
Physical controls like privacy screens limit visual eavesdropping by narrowing the viewing angle of your laptop or tablet. These are inexpensive and effective for preventing shoulder surfing in crowded areas.
Network controls focus on protecting data in transit. Encrypted Wi‑Fi (WPA/WPA2/WPA3) prevents casual observers on the same network from intercepting unencrypted traffic, while using a trusted virtual private network (VPN) encrypts your connection end-to-end.
Device and account controls reduce the impact if your device is lost or left signed in. Use strong, unique passcodes, enable full-disk encryption, and activate multi-factor authentication for accounts that hold sensitive data.
For organizations that handle public-facing operations or official duties away from a primary office, it can be helpful to coordinate policies and training with your wider risk management or insurance resources. For example, you can review coverage details relevant to public entities via Public Officials/Public Entity Program.
What it may cover (and what it may not)
These steps reduce the chance of accidental disclosure and make it harder for attackers to access data. They do not guarantee immunity from targeted attacks, device theft with advanced forensics, or malware that has already compromised a device.
Technical protections such as VPNs and encrypted websites (HTTPS) protect data in transit, but they do not protect information displayed on-screen or entered into an app that mishandles encryption. Know the limits of each control and layer protections accordingly.
Common mistakes to avoid
Assuming any public wireless network is safe is a frequent error; only connect to networks that use a current encryption standard and verify network names to avoid rogue hotspots.
Another common mistake is trusting mobile apps blindly for sensitive transactions. Some apps may not protect data properly; when possible, prefer well‑secured mobile websites or confirm the app’s security practices first.
Avoid using public or shared computers for private business, and never leave devices unattended while signed in to accounts with access to sensitive information.
Questions to ask an agent
If your organization requires regular work in public or has custody of sensitive records, discuss operational risk and insurance options with a specialist. For information on bond or official liability considerations, review pages such as Public Official Bonds and Public Entity Counties, Cities, Villages, Townships Insurance to understand coverage that may relate to offsite exposures.
Next steps
Before working in public, plan the task: postpone sensitive transactions if possible, use a privacy screen, enable your VPN, and close or lock unneeded applications. Make signing out and device locking part of your routine when you finish.
If you want personalized guidance on organizational policies or coverage options, talk to an agent who can review your situation and suggest appropriate protections.
Frequently Asked Questions
Is a privacy screen enough to protect my data in public?
A privacy screen helps prevent shoulder surfing but does not protect against network interception or malware; combine it with network encryption and device security.
Can I use public Wi‑Fi for work if I use a VPN?
A VPN greatly improves security on public Wi‑Fi by encrypting traffic, but ensure the VPN provider is trustworthy and that your device is free of malware.
Should I trust mobile apps for banking or sensitive transactions?
Some apps may mishandle encryption, so prefer a company’s mobile website when you are on public networks unless the app is from a trusted provider and has clear security assurances.
What if I must use a public computer for a quick task?
Avoid it whenever possible; public computers can have keyloggers or cached credentials, and you cannot verify their security.
