Before the Basic Anti-Virus, Advanced, Enterprise, or Value-added Plan edition of Security Center expires, you must renew your subscription to avoid service disruption. This topic describes how to renew the subscription to Security Center. You can renew the subscription within seven days after the expiration date to retain the current configurations and statistics.

Prerequisite

Before you renew the subscription, make sure that the total number of protected servers is no greater than the value of Protected Servers that you specified when you purchased the Security Center service.

Note
  • The Protected Servers parameter specifies the total number of assets protected by Security Center. The assets include Alibaba Cloud Elastic Compute Service (ECS) instances and external servers that have the Security Center agent installed. The default value is the total number of ECS instances and external servers that have the Security Center agent installed under your Alibaba Cloud account.If the number of protected servers is greater than the value of Protected Servers, the Renew button is dimmed and cannot be clicked. In this case, you must upgrade the edition of Security Center and increase that value. For more information, see Upgrade and downgrade Security Center.
  • If you have purchased the Value-added Plan edition, you can renew the subscription without the need to check the number of protected servers.

Expiration

Seven days before the Basic Anti-Virus, Advanced, Enterprise, or Value-added Plan edition expires, Security Center sends you an SMS message, email, or internal message that reminds you to renew the subscription. If you do not renew the subscription before the service expires, your assets are no longer protected by Security Center after the expiration date.

Security Center retains all your configurations and statistics for seven days after the expiration date. The retained configurations and statistics include your asset groups, tags, quarantined files, vulnerability whitelists, and baseline check policies. If you renew the subscription within seven days after the expiration date, you can continue to use the current configurations and statistics.

If you do not renew the subscription within seven days after the expiration date, the Basic Anti-Virus, Advanced, Enterprise, or Value-added Plan edition is downgraded to the Basic edition. In this case, you can no longer use the features provided by the current edition, or view the current configurations or statistics, such as DDoS alerts. You must subscribe to the Basic Anti-Virus, Advanced, Enterprise, or Value-added Plan edition again if you want to use the relevant features. For more information, see Purchase Security Center.
