Public Wi-Fi allows your team to stay connected on the go, but it can be insecure. Cybercriminals may log into a free network and try to access data on your devices, including login credentials or confidential client files. Exercise caution and follow smart practices when using a laptop, tablet, or smartphone on public networks.
Verify the network name
Before you connect, confirm the network’s name with an employee or the business. Attackers sometimes set up malicious networks with generic or misleading names like “Free Wi‑Fi” or names that mimic the establishment to lure users and enable man‑in‑the‑middle attacks.
Turn off file sharing
File sharing makes collaboration easier, but it also exposes files to others on the same network. Disable file and printer sharing on your device before joining public Wi‑Fi to reduce the risk of unauthorized access.
Use a VPN
A virtual private network (VPN) encrypts the connection between your device and a remote server, protecting data in transit. Consider reputable paid or free VPN options and install the VPN client on devices your team uses when working remotely.
Check for HTTPS
Look for HTTPS and a lock icon in the browser address bar before submitting sensitive information. HTTPS helps protect data between your browser and the website; you can also use browser extensions that enforce HTTPS for extra protection.
Enable two‑factor authentication
Two‑factor authentication (2FA) adds an extra step to logging in by requiring a one‑time code or approval from another device. If a password is compromised, 2FA helps prevent attackers from accessing accounts.
Update software
Keep your operating system, browser, and apps up to date to benefit from security patches. Install updates when connected to a trusted network and avoid downloading large updates while on public Wi‑Fi.
Forget the network
When you finish using public Wi‑Fi, sign out of websites, disconnect, and tell your device to forget the network. This prevents your device from automatically reconnecting the next time you’re nearby.
Limit your activity
Avoid accessing or transmitting highly sensitive work data over public networks. Save confidential work for a secure network whenever possible, and educate employees about safe habits and company policies.
If your organization needs guidance about public‑entity risks, see Public Officials/Public Entity Program for related resources and support.
Your company may rely on public Wi‑Fi to stay productive, so encourage employees to follow these steps and to report suspicious networks or activity. If you want to review options for coverage or discuss risk management, talk to an agent.

Frequently Asked Questions
How can a VPN protect me on public Wi‑Fi?
A VPN encrypts the traffic between your device and the VPN server, making it much harder for attackers on the same network to intercept your data.
Is HTTPS enough to keep me safe?
HTTPS protects data in transit to a website, but it does not secure your device from other network threats; combine HTTPS with a VPN and updated software for better protection.
Should I use public Wi‑Fi for banking or client work?
It’s safer to avoid banking and highly confidential work on public Wi‑Fi; wait until you’re on a trusted network or use a secure VPN if you must connect.
What should I do if I think my account was compromised after using public Wi‑Fi?
Change your passwords from a secure network, enable two‑factor authentication if not already active, and notify your IT department or service providers as needed.
