Features

HSS comes in basic, professional, enterprise, premium, web tamper protection, and container editions. It provides the following functions: Dashboard, Asset Overview, Server Management, Container Management, Server Fingerprints, Container Fingerprints, Vulnerability Management, Baseline Check, Container Image Security, Application Protection, Web Tamper Protection, Ransomware Protection, File Integrity Management, Virus Scanning, Dynamic Port Honeypot, Container Firewall, Application Process Control, Container Cluster Protection, Server Alarms, Container Alarms, Whitelist Management, Policy Management, Handling History, Security Reports, Container Audit, Installation and Configuration on Servers. The functions supported by each edition are different. You can select a proper edition based on your service requirements.

To protect test servers or individual users' servers, use the basic edition. It can protect any number of servers, but only part of the security scan capabilities are available. This edition does not provide protection capabilities.
If you have advanced protection requirements, you are advised to use the premium edition.
For servers that need to protect websites and key systems from tampering, the WTP edition is recommended.
For containers that need to enhance image security and container runtime security, the container edition is recommended.
If your servers store important data assets, have high security risks, use publicly available EIPs, or there are databases running on your servers, you are advised to use the premium or Web Tamper Protection edition.

You are advised to deploy HSS on all your servers so that if a virus infects one of them, it will not be able to spread to others and damage your entire network.
After you purchase a protection quota, you can upgrade or switch its edition. For details, see Upgrading Protection Quotas and Switching the HSS Quota Edition.

HSS Self-protection

Self-protection protects HSS files and processes.

Function	Description	Basic Edition	Professional Edition	Enterprise Edition	Premium Edition	WTP Edition	Container Edition
Windows self-protection	Prevent malicious programs from uninstalling the agent, tampering with HSS files, or stopping HSS processes. Supported OSs: Windows. NOTE: Self-protection depends on antivirus detection, HIPS detection, and ransomware protection. It takes effect only when more than one of the three functions are enabled. Enabling the self-protection policy has the following impacts: The agent cannot be uninstalled on the control panel of a server, but can be uninstalled on the HSS console. HSS processes cannot be terminated. In the agent installation path C:\Program Files\HostGuard, you can only access the log and data directories (and the upgrade directory, if your agent has been upgraded).	×	×	×	√	√	×
Linux self-protection	Prevent malicious programs from stopping the HSS process and uninstalling the agent. Supported OSs: Linux.
