Secure remote work and public WiFi

Remote work is convenient, but it extends a company’s security boundary to every home network, cafe WiFi and personal device. When employees connect from various places and devices, new attack points appear that did not exist on the office network. The good news — a few simple rules close most of these gaps.

Where the risk lies

• Public WiFi in cafes, airports or hotels, where others may monitor the traffic.
• Personal devices without protection used for work.
• A home network with an unchanged default router password.
• Screen visibility in public places — prying eyes and "shoulder surfing".
• More phishing, because remote workers handle more through email.

Core protection rules

• Use a company-approved VPN when connecting over an untrusted network.
• Avoid important actions (banking, logins) over open public WiFi.
• Enable 2FA on all work accounts — protection if a password is stolen.
• Lock your screen whenever you step away and use a privacy filter in public.
• Keep devices updated and disk encryption enabled.

Home network hygiene

• Change the default router admin password.
• Use a strong WiFi password and modern encryption.
• Update the router firmware.
• Keep work devices separate from questionable home devices where possible.

A simple rule when travelling: if the network is public, treat it as if someone is watching. For important actions, use a VPN or mobile data.

The human factor in remote work

Working outside the office, it is harder to quickly double-check with a colleague or IT, so an employee decides alone and faster — which scammers exploit. That is exactly why regular reminders and simulations matter especially for remote teams. Opsinel helps maintain alertness no matter where people work and shows which teams need more attention.
