Specifications of Different Editions

HSS provides Basic, Professional, Enterprise, Premium, Web Tamper Protection, and Container editions. It provides the following functions: Overview, Asset Overview, Host Management, Container Management, Asset Fingerprint, 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, Host Intrusion Detection, Container Intrusion Detection, Whitelist Management, Policy Management, Historical Handling Records, Security Reports, and Security Configurations. 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, nor does it provide support for DJCP Multi-level Protection Scheme (MLPS) certification. For a server that uses the basic edition for the first time, this edition is free of charge for 30 days.
If you need to obtain the DJCP MLPS L2 certification, purchase the enterprise edition.
If you need to obtain the DJCP MLPS L3 certification, purchase the premium edition.
If you need to obtain the DJCP MLPS certification for a website, you are advised to purchase the Web Tamper Protection 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, container runtime security, and to comply with security regulations, 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 edition, you can upgrade or switch the edition. For details, see Upgrading Protection Quotas and Switching the HSS Quota Edition.

Server self-protection

Server self-protection is a self-protection function of HSS.

**Table 25** Server self-protection
Function	Description	Basic Edition	Professional Edition	Enterprise Edition	Premium Edition	WTP Edition	Container Edition	Supported OSs
Self-protection	Protect HSS files, processes, and software from malicious programs, which may uninstall HSS agents, tamper with HSS files, or stop HSS processes. 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 HSS agent cannot be uninstalled on the control panel of a server, but can be uninstalled on the HSS console. HSS process 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).	×	×	×	√	√	×	Windows
