Constraints and Limitations

Supported Server Types

  • ECS
  • Third-party cloud server
  • On-premises server

Supported OSs

HSS uses the agent to monitor security risks and defend against external intrusions. To protect a server with HSS, ensure the agent is up and running on the server. For more information, see Table 1.

  • The agent is probably incompatible with the Linux or Windows versions that have reached end of life. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.
