: It takes the connection information provided by the Privileged Session Name Web Access (PVWA) and establishes the secondary connection to the final target system.
: The PSMConnect and PSMAdminConnect users require Read & Execute permissions on the executable and its parent folder.
: Usually located at C:\Program Files (x86)\CyberArk\PSM\Components\PSMInitSession.exe . Operational Requirements To function correctly, the following must be in place: psminitsessionexe
When an administrator connects to a sensitive target asset through the CyberArk Password Vault Web Access (PVWA) , the platform delegates the connection to the PSM Server. Rather than opening a standard Windows Desktop, the system isolates the user inside a highly restricted, audited sandbox. This architecture functions entirely around psminitsession.exe .
Windows operates with , a security feature introduced in Windows Vista. Session 0 hosts system services and non-interactive processes, while user sessions (Session 1, 2, etc.) handle interactive applications. This separation prevents services from directly interacting with user desktops.
You might see in event logs:
If you are unsure, engage your security team or run an offline malware scan. psminitsessionexe is not a native Windows component – it was placed there intentionally, either by your security team or by an adversary. Know which one applies to you.
To verify its functionality, administrators often temporarily replace it with notepad.exe in the user's environment settings; if Notepad launches successfully upon connection, it confirms the issue lies with the CyberArk component itself rather than the Windows Remote Desktop configuration [10, 16, 21].

Windows Group Policy can sometimes override CyberArk’s logic, forcing a full desktop to load instead of the PSMInitSession wrapper.
keys can prevent new sessions from starting until the server is rebooted. Verification Method
: It enables the recording, monitoring, and isolation of privileged sessions. If unsigned or signed by an unknown publisher,
: It ensures that the user session is restricted to the specific administrative tool or application requested, rather than providing a full desktop environment. Common Issues & Troubleshooting If you encounter errors like "This initial program cannot be started"
