Glossary
Session Supervision and Monitoring is the real-time oversight of active user sessions by administrators or security personnel. This includes observing live activities, receiving alerts for high-risk actions, and optionally intervening, such as pausing or terminating sessions, when unauthorized or unsafe behavior is detected. Unlike passive logging, session supervision enables active defense and situational awareness during remote or privileged access to critical systems.
In critical infrastructure environments, where system interactions can directly impact safety, uptime, and compliance, visibility into live user behavior is essential. Real-time session monitoring empowers organizations to enforce operational integrity, detect policy violations, and respond to anomalous activity before damage occurs.
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.
Supervision and monitoring are called for in several compliance frameworks, including NERC CIP, IEC 62443, NIS2, and TSA SD02E, which require active governance over privileged or remote access. Having real-time visibility into sessions is not just a security best practice, it’s a compliance and operational requirement.
Xona delivers native, real-time session supervision tools that enable administrators to observe, intervene, or take control of active sessions across IT and OT systems, all without requiring agents or additional software. Through Xona’s secure browser interface, supervisors can shadow live sessions, receive alerts based on user actions, and immediately suspend or terminate access if a risk is detected.
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.
Session supervision allows administrators to observe live user activity, ensuring that actions taken during remote sessions align with security policies and operational practices.
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.
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.
Frameworks like NERC CIP, IEC 62443, TSA SD02E, and NIS2 emphasize the need for monitoring privileged access and maintaining active control over remote sessions.
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.
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.
