Some free VPNs make money by letting other people send traffic through your internet connection.

Google recently took down a large network that used devices running apps advertised as free VPNs.

While the VPN worked, the app also allowed other customers' internet traffic to pass through the device.

On a work laptop, that traffic would appear to come from your company's public IP address. Your IP could get blocked because of activity nobody in the business carried out.

Google also found that some of this software could expose other devices on the same network.

Check which VPNs and browser extensions are installed on company devices. Staff should use the VPN provided by the business, not one they found online because it was free.

Want to know whether unapproved VPNs or proxy software are installed on your company devices? Reach out and we can check for you.

Your out-of-office reply shouldn't tell strangers where you are, which clients you're working with or who is covering for you. People outside your company only need to know when you'll reply and how to contact the business if it's urgent.

Don't trust hotel Wi-Fi. It can be compromised even when you've joined the correct network.

Microsoft has found attackers taking control of the systems used for Wi-Fi login pages at hotels and conference venues.

Once the login system has been compromised, guests can be redirected to a fake Microsoft 365 sign-in page or shown a fake browser update that installs malware.

The timing makes the request believable. You've just connected, the hotel page opens and it says an update is needed before you can continue.

Checking the network name with reception won't help because the hotel's real Wi-Fi is involved.

Use your phone's hotspot for work whenever possible. If you have to use hotel Wi-Fi, never enter your work password into the hotel registration page.

And if the page asks you to download an update, certificate or security tool, disconnect. Joining Wi-Fi shouldn't require you to install anything.

If your staff travel with work laptops, send us a message before their next trip. We'll make sure the devices are properly protected.

A short power cut can shut down your server, firewall or network equipment. A UPS battery gives those devices time to stay on or shut down safely. Ask your IT provider which equipment has power protection and when the batteries were last tested.
