What Is a Firewall?
A firewall is like a security guard for your computer. It watches the flow of information moving in and out, allowing safe traffic while blocking anything suspicious or unauthorized. By filtering harmful connections, it reduces the risk of hackers gaining access or unwanted programs secretly sending data.
With Intego ONE, firewall protection is built in and simple to use. You get clear visibility of your network activity, easy-to-manage controls, and instant alerts when something looks unusual, so you can stay safe without needing to be a security expert.
How Does a Firewall Work?
01
Monitoring all connections
Your computer is always exchanging data online. Intego’s firewall carefully monitors every connection, ensuring only safe and trusted traffic is allowed through.
02
Blocking suspicious activity
When an app or process attempts to send or receive harmful data, the firewall intervenes immediately to block the activity and maintain your system's security.
03
Keeping you informed
If something unusual occurs, Intego provides clear and timely alerts. You’ll always know what’s happening without needing to interpret complex technical details.
04
Working with antivirus & VPN
A firewall is one layer of security, but it works best as part of a complete system. With Intego ONE, the firewall, antivirus, and VPN work together to protect your device and keep your online activity private.

Understanding Firewall Protection
A smart firewall adds another layer of defense, preventing threats from spreading or stealing your data.

What do firewalls protect against?
Unauthorized remote access
Botnet and ransomware activity
Suspicious programs “phoning home”
Malware communicating with external servers
Phishing links attempting backchannel access
Do firewalls protect against viruses?
A firewall can’t remove viruses on its own, but it prevents infected apps from spreading or leaking data. That’s why Intego ONE combines firewall and antivirus protection for complete security. Together, they stop threats at every stage — blocking suspicious connections before infection and removing malware if it gets through.
Does my computer already have firewall protection?
While macOS includes a built-in firewall, it’s off by default and offers little visibility. Intego ONE adds easy controls, clear alerts, and deeper protection. You’ll see exactly what’s happening on your network, get instant notifications about suspicious activity, and stay in control of every connection.
The Complete Security Trio
Firewall, antivirus, and VPN - each tool protects in its own way. Together, they keep your Mac fully secure.

Firewall
A firewall monitors and filters network traffic, allowing safe connections and blocking anything suspicious. It acts as your first line of defense against intruders.

Antivirus
Antivirus software detects and removes threats already on your computer, from common viruses to advanced ransomware. It ensures harmful files are eliminated quickly.

VPN
A VPN encrypts your internet traffic and hides your IP address. This keeps your browsing private and protects your identity on any network.
