WatchGuard APT Blocker is a subscription-based service that adds another layer of UTM protection beyond signature-based antivirus.* Using a cloud-based sandbox to run Windows executable files, Microsoft Office, PDF files and Android APK it looks for malware characteristics, including multiple types of evasive behaviour. APT Blocker integrates with WatchGuard Dimension providing logs, proactive alerts and full visibilty into any files detected as malware. Renew your existing subscription or extend your protection with APT Blocker for one year. APT Blocker is not included in the UTM Security Bundle or Security Suite.
