McAfee Firewall Features

McAfee Firewall Advanced Protection:

In addition to filtering data, the McAfee firewall also provides a complete inbound and outbound firewall protection. It protects your computer from hacker probes, blocks spyware, Trojans, and keyloggers.

The firewall monitors internet and network traffic, alerts users to hostile activities, and provides detailed information about internet traffic.

Smart Internet Access Control for Programs:

You can use the Firewall’s alerts and event logs to control how your programs access the internet and manage internet access for applications through alerts and event logs. You can also limit internet access for specific programs on the firewall’s Program Permissions tab.

Control Your Computer Connections and Lockdown Firewall:

Instantly sever all connections and limit internet traffic between your computer and the internet. With McAfee Firewall, you can trust and ban remote connections and IP addresses that could connect to your PC.

Advanced Malware Detection:

Combines program access control with an enhanced malware database to detect and block potentially unwanted programs and malicious applications— including spyware, Trojans— from accessing the internet.

Computer Startup Protection:

The firewall protects your computer during startup. Boot time protection blocks new programs — without prior permissions — from requesting access to the internet. Upon launching, McAfee Firewall displays alerts for applications that had required access to the internet during startup, which you can grant or deny.

Monitor and Analyze Internet Traffic:

View legible graphs showing the origins of hostile intrusions and attacks. Furthermore, gain access to detailed owner information and geographical data for originating IP addresses. Track program bandwidth and activity, including those that are actively listening for open connections.

Pause Intrusion Alerts When You Are Busy:

You can pause intrusion and suspicious events when you are focused on other essential activities like video conferences, gaming, watching movies, and so on. Set the firewall to display these alerts when you complete the computer game.

Protect your privacy by enabling automatic intrusion prevention. In comparison to other security systems, McAfee provides a higher level of protection by blocking processes that display characteristics of hacking attempts.

Is McAfee Firewall Free?

Unfortunately, the latest version of the McAfee Firewall is not free for download. The firewall is included in a McAfee Total Protection software package. McAfee offers a 1-year license covering unlimited devices for USD 44.99 for the first year. Afterward, you will have to pay up to USD 119.99 per year.

McAfee Firewall Pros and Cons

McAfee has taken several measures to improve protection for computers and networks. However, to complete our McAfee Firewall review, we will list some upsides and drawbacks of this software program.

Cons

  • The Settings controls are scattered across different tabs on the software’s interface, making it challenging to locate specific controls
