Public Wi-Fi helps you stay connected on the go. With this resource you can check work email, video chat with clients, or review inventory logs in a restaurant, hotel, or airport. Unfortunately, public Wi‑Fi poses a security risk because others on the same network can see much of the activity you perform online. Follow these tips to use public Wi‑Fi more safely and protect yourself and your company.
Avoid Phony Wi‑Fi
Hackers can run “man‑in‑the‑middle” attacks by creating a Wi‑Fi network that looks legitimate but is controlled by an attacker. If you log into that network, the attacker can monitor your traffic and capture credentials. Before you connect, verify the network name with the venue’s staff.
Access Only Secure Websites
Look at the address bar: website addresses that start with https indicate the connection is encrypted. When you’re on public Wi‑Fi, limit browsing to pages served over https so data sent between your device and the site is protected.
Limit Public Wi‑Fi Activity
Even short sessions can be risky because data you enter might be exposed. Avoid accessing sites that require passwords or credit card details while on public Wi‑Fi, including online banking, email, and shopping sites.
Disconnect from Public Wi‑Fi
Turn off automatic Wi‑Fi connections on your device so it won’t join networks without your approval. Manually connect only to networks you’ve verified as safe.
Utilize a VPN
A virtual private network (VPN) creates an encrypted tunnel for your internet traffic and improves security on public networks. Consider using a reputable VPN service, especially when accessing sensitive work resources from a smartphone or laptop.
Use Your Smartphone as a Mobile Hotspot
Using your phone’s cellular connection as a personal hotspot is often safer than public Wi‑Fi. You should still be cautious about the sites you visit and the data you share, but a hotspot reduces exposure to nearby network attackers.
Purchase Cybersecurity Liability Insurance
Despite precautions, data, devices, or accounts can still be compromised on public networks. Ensure you purchase adequate cybersecurity liability insurance to help protect your company’s assets if a breach occurs.
If your company or organization needs coverage, review program options like Public Officials/Public Entity Program and Public Entity Insurance for Counties, Cities, Villages and Townships.
Improve security as you travel away from the office by following these tips; they help you use public Wi‑Fi in a safer manner while you work. If you have specific coverage questions, talk to an agent.
