What Is a Firewall? (Do You Really Need One?)

Dr. Scurry Blacktail *LOVES* it when networks are unprotected!
A firewall is your network’s security guard.
It controls what gets in and what gets out. If something looks suspicious—it blocks it.
Simple enough, right?
Here’s where it gets interesting…
Most ISPs give you a router with a built-in firewall.
That’s great—in the same way a screen door is great… until winter shows up.
If you’re running a business—even a small one—you need something stronger:
- Better filtering
- Regular updates
- Actual logging and visibility
Because here’s the truth:
👉 Even a single computer connected to the internet gets scanned and probed constantly.
Most people just never see it happening.
