The firewalls support well-known Zyxel security services such as web and application security, malware blockers, etc., as well as sandboxing and botnet filtering. An appealing ATP dashboard provides a quick overview of currently detected threats. With the latest software and hardware, the ATP firewall delivers very high performance, even when all security features are in use.
Cloud intelligence receives unknown files or user patterns from requests across all ATP firewalls. It then identifies and archives the inspection results in the cloud threat database. The highest-rated threats are shared with all ATP firewalls, ensuring that they are continuously protected against new unknown threats. With real-time cloud synchronization, cloud intelligence is continuously evolving into a security defense ecosystem. All ATP firewalls are synchronized with cloud intelligence and adaptively respond to every new threat.
Sandboxing utilizes an isolated environment in the cloud to analyze unknown files that cannot be identified by existing local security tools such as antivirus software. Sandboxing evaluates the behavior of files in an isolated environment to detect potential threats. This approach allows for the detection of completely new and unknown malware, preventing it from entering a network. The cloud sandbox of the ATP firewall series, in conjunction with cloud intelligence, provides optimal protection against all types of zero-day attacks.
