The Allied Telesis Self-Defending Network automatically detects and responds to threats within a corporate network, working alongside existing firewalls to instantly isolate compromised devices, whether wired or wireless, without requiring endpoint software agents. It monitors internal traffic without introducing latency by operating in a one-armed mode, allowing it to block threats immediately. It integrates with various security appliances and network switches through OpenFlow or proprietary APIs, enabling centralized security policy management and automatic threat containment.
