Our Verdict

Best for

Home users who want a free two-way firewall with the option to add antivirus and ransomware protection from the same vendor.

Skip if

You need enterprise-grade network firewall management rather than a consumer desktop suite.

What is ZoneAlarm?

ZoneAlarm is a long-running personal security brand now owned by Check Point Software Technologies, built around a two-way firewall that inspects both inbound and outbound traffic. It pairs that firewall with real-time antivirus and anti-spyware scanning, anti-phishing protection, and threat emulation aimed at catching zero-day threats before they execute. The product line ranges from a free firewall and free antivirus up through paid tiers like ZoneAlarm Pro Antivirus + Firewall and ZoneAlarm Extreme Security NextGen, which adds ransomware protection and broader coverage. Apps are available for Windows, Mac, Android, and iOS, and the suite has picked up awards such as PCMag Editors' Choice and AV-Test certifications over the years.
