IronWall

IronWall vs. the alternatives.

Most landing pages overstate. We don't. If a paid AV does something IronWall doesn't (kernel drivers, cloud sandboxing), we'll say so right here.

Where IronWall wins
  • Truly free, forever — no upsell tier.
  • Open source. Audit it before you trust it.
  • Zero telemetry. No analytics, no fingerprinting.
  • Tiny: 5 MB installer vs. 200–500 MB for paid suites.
Where IronWall loses (today)
  • No kernel-mode driver. Bitdefender and Defender catch some rootkit-class threats we don't.
  • No cloud sandbox. We can't detonate suspicious files in a remote VM.
  • Smaller signature pool than enterprise vendors who scrape 50+ feeds.
  • Brand-new project. Years of field-testing matters; we don't have that yet.
