Automated scanning: Virusfree stops up to 10-times more malicious emails than the other solutions can. Our multi-layer filter automatically scans and control all emails and attachments almost instantly thanks to the real-time dynamic threat analysis. This includes an AI botnet detector, which is capable of recognising malicious emails sent from botnets and will stop them even when other security solutions do not. That means you'll get safe emails delivered to your inbox quickly, but threatening emails will be blocked.
