Secure Remote Access (SRA) enables authorized users, including employees, contractors, and third-party vendors, to remotely access critical systems while applying controls around identity, authentication, authorization, and user activity. OT secure remote access (OT SRA) applies these capabilities to operational technology and industrial control system environments, where access must account for system availability, legacy assets, third-party access, and auditability.
Unlike traditional IT remote access, OT SRA provides users with controlled access to specific operational systems while reducing direct exposure of the underlying OT network. Modern approaches can also provide session monitoring and recording, giving organizations greater visibility and control over remote activity.
OT secure remote access (OT SRA) provides authorized users with remote access to operational technology and industrial control system assets while limiting exposure of the underlying OT network. Unlike traditional IT remote access, OT SRA is designed for operational environments where system availability, legacy assets, third-party access, and auditability are critical considerations.
Xona provides browser-based access to the specific OT and ICS assets a user is authorized to access without placing the user's endpoint directly on the OT network. Protocol isolation, identity-based access, session recording, and centralized controls help keep remote activity controlled and audit-ready.
Critical infrastructure organizations increasingly rely on remote access for maintenance, troubleshooting, vendor support, engineering, and other operational work. In OT and ICS environments, that access needs to be carefully controlled because remote users may be connecting to systems that support critical operations.
Secure remote access helps organizations limit users to the systems they are authorized to access while applying identity-based authentication, least-privilege controls, and oversight of remote sessions. Session monitoring and recording can also provide a reviewable record of remote activity.
These capabilities can support security and regulatory readiness by helping organizations demonstrate how remote access is controlled and monitored. Requirements vary by industry and jurisdiction, so secure remote access should be considered part of a broader security and compliance program rather than a compliance solution on its own.
Xona provides purpose-built secure access for OT and ICS environments. Authorized users receive browser-based access to the specific assets they need without placing their endpoints directly on the OT network.
Xona uses protocol isolation, identity-based access, least-privilege controls, and session monitoring and recording to give security and operations teams greater control over remote activity. Access can be limited by user, asset, session, and time, while recorded sessions provide evidence that can support audits, investigations, and access reviews.
By separating user endpoints from the OT network, Xona helps organizations reduce the exposure created by traditional remote-access approaches while keeping legitimate operational access fast and usable.
