Session Manager Plugin

Session Manager Plugin 1.2.804.0, published by Amazon Web Services, is a command-line add-on that extends the AWS CLI so administrators can establish secure interactive sessions to Amazon EC2, on-premises servers, and virtual machines without opening inbound SSH or RDP ports. Operating as the client-side component of the fully managed AWS Systems Manager Session Manager capability, the plugin negotiates an encrypted WebSocket tunnel between the local workstation and the targeted managed instance, relaying keystrokes and screen output through the regional Session Manager service endpoint instead of over the public internet. Typical use cases include Linux shell access, Windows PowerShell remoting, one-off patching, log inspection, troubleshooting, and issuing ad-hoc commands across hybrid fleets while maintaining centralized audit trails in AWS CloudTrail and optional Amazon S3 session logging. Because traffic traverses the existing SSM agent already present on instances, security groups can remain closed, eliminating the need for bastion hosts or key management. The plugin is refreshed regularly; sixteen numbered releases have appeared to date, each aligning with new CLI options, proxy support, credential profiles, and regional endpoints. System administrators install the component on Windows, macOS, or Linux workstations, after which the aws ssm start-session command becomes available for seamless connection initiation. The utility falls within the Remote Computing category and integrates with standard AWS credential chains, IAM policies, and Resource Tag-based access controls for granular authorization. Session Manager Plugin is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
