What is a firewall and do you need one?
A firewall is like a security guard that sits between your computer and the internet. It blocks unwanted connections trying to get in and watches suspicious outgoing activity. Windows and macOS both come with a firewall turned on already, so you don't need to buy one separately.
A firewall is security software that controls what gets in and out of your computer. It blocks hackers from sneaking in through the internet and stops malware from sending your information out without you knowing. Both Windows Defender Firewall and macOS's built-in firewall are good and they're already turned on. You don't need a separate firewall program.

Common mistakes to avoid
- Thinking you need to buy a separate firewall program — you don't, the one included with your computer is fine
- Turning off the firewall to fix a printer or gaming issue — the real fix is to allow that specific program through, not turn off the whole firewall
- Assuming a firewall will slow your computer down — the built-in firewalls are lightweight and won't slow you down
Signs you need professional help
- Your firewall is turned off and you don't know how to turn it back on
- A program you trust is being blocked and you need help allowing it through
- A program is telling you to turn off your firewall to use it
