According to the web search results, the chief benefit of PSM is to provide both privileged session isolation and privileged session recording. Privileged session isolation means that the PSM server acts as a proxy between the user and the target machine, preventing the user from directly accessing the target machine or exposing the privileged account credentials. Privileged session recording means that the PSM server captures and stores a video and a transcript of the user's activity on the target machine, enabling auditing and monitoring of the privileged session. These benefits help to enhance the security and compliance of the privileged access management solution, as they prevent credential exposure, restrict unauthorized access, detect malicious activity, and provide evidence for forensic analysis
