NetSupport Manager is a remote control and IT management tool designed for organizations to manage devices across a network. The product focuses on secure remote access and has been in development for approximately 35 years. The tool includes several security mechanisms to control and audit remote connections: **NetSupport Gateway:** A locally installed gateway component that generates encrypted passcodes ("keys") required to authorize connections between machines. It also logs all connection activity for traceability. **Security Keys:** A configurable authentication mechanism that restricts connections to Control users who possess the matching key as the Client. Keys can be set as an organization-specific serial number or a custom passcode. **User Acknowledgement:** A feature that requires the client-side user to explicitly accept an incoming connection request before access is granted, preventing unauthorized forced connections. Beyond these built-in security features, NetSupport Manager supports broader security hygiene practices for its users, including guidance on phishing awareness, software patch management, antivirus integration, and review of unused security settings. The vendor also offers health check services to review and optimize security configurations. The product serves over seven million users across multiple industries and is available as a commercial solution with a free trial option.
