Quick tip for any Gwinnett County small business that lets customers, vendors, or guests connect to your Wi-Fi.

If your guest Wi-Fi is just the same network you use for your business, you've got a problem. Here's why.

Every guest device on your network is one click away from being a foothold for an attacker. A customer's phone with an outdated app. A vendor's laptop that's been compromised. A contractor running who-knows-what. All of them now sit on the same network as your file server, your printers, and your point-of-sale system.

The fix is pretty simple. Set up a separate guest network on your business router or Wi-Fi access points. Guests get internet. They don't get a route to anything else.

A few things to check while you're at it:

The guest network is clearly named. Something like "YourBusiness-Guest" so people pick the right one.

The guest network has its own password, changed periodically.

There's no link between guest and business networks. Most modern Wi-Fi gear has a "client isolation" setting that handles this.

If your current setup is one Wi-Fi password shared with customers, employees, and the cleaning crew, that's worth fixing this week.

We help small businesses across Gwinnett County set up business-grade Wi-Fi the right way. Give us a call if you want a second set of eyes.

Quick question for Gwinnett County business owners: when was your last backup?

Not when you set it up. When it actually ran and completed successfully.

If you don't know the answer, that's a problem. Here's a quick backup checklist:

1. Is your backup running automatically every day? Check the logs to confirm.
2. Have you tested a restore in the last 90 days? A backup you've never tested is a backup you can't trust.
3. Do you follow the 3-2-1 rule? 3 copies of your data, on 2 different types of media, with 1 stored offsite.
4. Are your backups encrypted? If someone steals your backup drive, can they read your data?
5. Does your backup include everything? Email, databases, cloud apps, not just files on the server.

Ransomware, hardware failures, and human error can all wipe out your data. Backups are your safety net. Make sure it actually works.
