Session Supervision and Monitoring

Identity Access Management

What is Session Supervision and Monitoring?


Session supervision and monitoring is the real-time observation and control of active user sessions within a secure remote access environment. It enables administrators to view user activity as it happens, intervene when necessary, and terminate sessions that violate security or operational policies. In OT and ICS environments, session supervision provides critical visibility into remote activity involving sensitive systems and assets.


Why is Session Supervision and Monitoring Important?


This capability is particularly crucial when access is granted to third-party users, such as vendors or OEMs, who may have deep privileges but limited contextual awareness of system sensitivities. Without session supervision, organizations risk delayed responses to misconfigurations, unauthorized changes, or malicious activity, all of which can disrupt operations or violate regulatory mandates.

Session supervision and monitoring can support security and regulatory requirements across frameworks such as NERC CIP, IEC 62443, NIS2, and TSA security directives by providing greater visibility and control over privileged and remote access.  Session monitoring and recording can also provide evidence that supports audits, investigations, and access reviews. 

How Does Xona Help with Session Supervision and Monitoring?


Xona provides centralized session management for remote access to OT and ICS environments. Security and operations teams can monitor active sessions in real time, record user activity for audit and review, and terminate sessions when necessary. These controls help organizations maintain oversight of remote activity while supporting least-privilege access and audit-ready session evidence. 

This is especially valuable in critical environments where access is time-sensitive, high-risk, or involves external users. Xona’s session monitoring is tightly integrated with policy enforcement, audit logging, and identity verification, creating a complete access governance loop.

Unlike legacy PAM or VPN-based tools that may require separate integrations or lack real-time controls, Xona provides this functionality out of the box. It is purpose-built for operational teams who need visibility into what’s happening now, not just what happened after the fact.

Frequently Asked Questions

What is the purpose of session supervision during remote access?

Session supervision allows administrators to observe live user activity, ensuring that actions taken during remote sessions align with security policies and operational practices.

How does session supervision differ from session logging?

While session logging captures historical data for later review, session supervision provides real-time visibility and allows administrators to respond immediately to unsafe or unauthorized behavior.

Why is real-time session monitoring important in OT environments?

It enables rapid detection and intervention in situations where user actions could affect physical safety, system availability, or regulatory compliance, especially where third parties might be involved.

Which compliance standards require or recommend live session monitoring?

Frameworks like NERC CIP, IEC 62443, TSA SD02E, and NIS2 emphasize the need for monitoring privileged access and maintaining active control over remote sessions.

How does Xona support session supervision and intervention?

Xona provides real-time session shadowing, alerting and admin controls to pause, terminate, or take over on-going sessions. And this is all through a secure, browser-based interface without endpoint agents.

Can session supervision be used to manage vendor or OEM access?

Yes, Xona’s session supervision tools are especially useful for overseeing external users, like third-party vendors, contractors and OEMs to ensure their access remains controlled, accountable, and within approved operational boundaries.
