ZoneAlarm Pro combines Check Point’s world-class firewall technology with a capable antivirus engine to create a security solution focused on network protection. The 2026 version is particularly strong for users who need advanced firewall controls alongside traditional antivirus.

Firewall and Network Protection

ZoneAlarm’s firewall, developed by Check Point Software Technologies, is considered one of the most robust personal firewalls available. It controls both inbound and outbound traffic with granular rules, and automatically stealths your ports from unauthorized scanning.

Features

• Check Point firewall engine
• Antivirus and anti-spyware protection
• Zero-hour emergency response
• OSFirewall (application-level control)
• Wireless network protection
• Identity theft protection and credit monitoring
• Online backup (5GB)
• Game mode

Verdict

ZoneAlarm Pro is the go-to choice for power users who want maximum control over their network traffic. The Check Point firewall is exceptional, though the antivirus component is slightly behind the best dedicated AV engines.
