Best for a free firewall for a Windows PC

ZoneAlarm offers a free antivirus and a free firewall for PCs, with paid suites above them. No plan price could be read, and the threat emulation and mobile protection are only on the top suite.

Who ZoneAlarm is for

  • Fits if you want a free firewall or antivirus on a PC
  • Works for someone who wants one paid suite across PC and phones

Who ZoneAlarm is not for

  • Skip it if you want to compare prices first, as none could be read
  • Tight if you stay on the free downloads, which cover PCs only
  • Watch out: threat emulation and mobile protection are only on Extreme Security
  • Watch out: products other than Extreme Security list fewer platforms

Why ZoneAlarm gets a 2.6

Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

  • CValue for moneyNo plan prices are recorded, so it sits in the middle of antivirus where no price is published.
  • BFree plan and trialFree Antivirus and Free Firewall downloads are offered for PCs, with no time limit. One person could live on them.
  • CFeaturesTwo-way firewall, antivirus, anti-phishing and anti-ransomware, but threat emulation and the mobile protections are listed only for Extreme Security NextGen.
  • BEase of useNo store rating on record. It is installed software with nothing to configure to start.
  • BPlatforms and integrationsExtreme Security NextGen lists Windows, macOS, Android and iOS. The other products list fewer platforms. No integrations listed.

Keep ZoneAlarm, or make your own?

Keep it

To replace ZoneAlarm you would be making an engine that recognises new malware as it appears. That is not a weekend's work, with an AI app builder or without one.

What you could not

  • An engine that recognises new malware as it appears.
  • Apps for macOS, Windows, iOS and Android that stay in step with each other.
  • AI features, unless you pay a model provider for each request yourself.

What this rests on. ZoneAlarm’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.

What is ZoneAlarm?

ZoneAlarm is a home security line from Check Point Software Technologies. It includes free firewall and antivirus downloads, paid Pro Antivirus + Firewall and Extreme Security NextGen suites, a separate Anti-Ransomware product and a mobile security app. Prices could not be read from the site during this check.

Worth knowing

  • Plan prices are not recorded: the product and pricing pages answered with a bot check, so nothing could be read.
  • The home page lists Extreme Security NextGen for Windows, macOS, Android and iOS; the other products list fewer platforms.
  • Threat emulation and the mobile protections are listed only for Extreme Security.
