Explore Xona System's Self-Guided Tours

Xona Centralizer was designed to unify and manage all Xona gateways within a network from a single control plane. It provides centralized administration, streamlined policy enforcement, and enhanced scalability across large or complex environments. It connects all the gateways together and will sync connections and related permissions to all the gateways. This gives you auditable sessions letting you know the connection types, files transferred, and relay access approval to employees or contractors.

Third-party vendors and OEMs are essential to industrial operations, providing critical maintenance and diagnostics for systems like PLCs and SCADA. However, this necessity introduces a primary threat vector. External users typically connect from unmanaged devices over untrusted networks, bypassing traditional enterprise governance. Because these connections often rely on high-privilege shared credentials and broad VPN tunnels, they create significant lateral movement risks and exposure paths that compromise safety and uptime.

Identity based access for OT and ICS marks a critical shift from broad, network centric connectivity to a Zero Trust model where access is granted based on verified identity, explicit policy, and session-level control. Traditional methods like VPNs and jump servers often create excessive standing access and visibility gaps, particularly problematic for legacy industrial systems that rely on shared credentials or unmanaged vendor paths. Xona addresses these challenges by brokering access through a protocol terminating, browser-based gateway that ensures industrial protocols never traverse the user side interface. This architecture provides granular, time bound control and replaces forensic nightmares with searchable session recordings that tie every action to a specific individual. Beyond security, this approach enhances operational resilience by allowing real-time supervision without physical presence and accelerating root-cause analysis from day to minute. Crucially, it provides the compensating controls required for high stakes compliance frameworks like NERC CIP and TSA SD-02F, enabling organizations to maintain strict audit trails and satisfy regulatory requirements without disrupting essential industrial workflows.
