Xona Systems Unveils Active Defense for Enhanced Remote Access Security

Xona Systems has launched Active Defense, a capability designed to automatically halt threats during live remote access sessions in operational technology (OT) environments. This innovation addresses the critical gap between detecting suspicious activities and stopping active sessions, which can take minutes to hours, leaving systems vulnerable. The Active Defense feature integrates with OT Asset Visibility and Vulnerability Platforms, enabling real-time enforcement actions such as session termination and access restrictions. This is particularly vital as remote access pathways are increasingly targeted by attackers, including nation-state actors, as highlighted by recent CISA advisories. The system minimizes operational disruptions while enhancing security response times. Active Defense is now part of the Xona Secure Remote Access platform, supporting both on-premises and hybrid OT environments.

Key Points: • Xona Systems launched Active Defense to enhance security during remote access sessions. • The capability allows for automatic threat response, reducing the time to act on suspicious activity. • Active Defense integrates with existing OT security platforms to minimize operational disruptions.
