What Is a Firewall?

A firewall sits between your devices and the internet. It checks traffic and stops threats. You get peace of mind with one running.

Bad guys try to sneak in all the time. Your firewall spots them and shuts the door. Simple as that.

Types of Firewalls You Need to Know

You see different kinds out there. Each one works in its own way. Pick based on what you do.

Software Firewalls

These run on your computer or phone. Norton and McAfee make good ones. They guard one device at a time.

You install software like Norton 360. It watches what comes in and out. Costs around $40 first year.

Hardware ones are boxes you plug in. Cisco Firepower or FortiGate do the job. They protect your whole network.

FortiGate 100F handles 1 Gbps speed. Great for small offices. You connect everything behind it.

Next-Gen Firewalls (NGFW)

NGFWs do more than basic blocks. They check app traffic and stop malware. Palo Alto and Fortinet lead here.

Latency adds delays. Low latency keeps things snappy. Gaming and video calls need this.

Concurrent sessions show how many connections it handles. Businesses need high numbers. Home use? Few hundred works.

Check vendor specs before buying. Real-world tests vary. Reviews tell the truth.

Security Features That Work

Antivirus scanning catches known malware. Sandboxing tests suspicious files in isolation. Both stop nasties cold.

Geo-blocking shuts out countries you don't deal with. Cuts attacks by half sometimes.

Two-factor auth for firewall admin. You lock down access tight. Nobody sneaks in.

SSL inspection opens encrypted traffic. Threats hide in HTTPS. This reveals them.

• Threat intelligence feeds update hourly.
