ZoneAlarm Free Firewall

ZoneAlarm is a firewall that is meant to protect a Windows computer. It is developed by Check Point Software Technologies and monitors incoming and outgoing traffic, blocking unauthorized connections in both directions. It comes with multiple layers of protection and allows the user a lot of control over which programs may access the network.

ZoneAlarm also comes in paid editions, such as ZoneAlarm Pro Firewall and ZoneAlarm Extreme Security, and they add protection that the free firewall doesn't give, for example antivirus and anti-ransomware modules. This is useful for someone who feels that they might need a little bit more protection than the average user. 

The free firewall includes WiFi protection for unsecured public networks, anti-bot protection that detects and blocks harmful bots, early boot protection against rootkits and component control that stops malicious DLL injection. The preferences let you lock the configuration with a password, back up and restore security settings and set up a proxy server.

Ultimately, ZoneAlarm is an overall good firewall. It comes in several editions, and it allows the user a lot of freedom to decide which programs may connect to the Internet. It also comes as a free or a paid product, allowing users to choose the best option for their computer usage. Alerts and logs show blocked connections and program events. Note that the free firewall is designed to work alongside Windows Defender and is not compatible with other anti-malware software.
