Before the Anti-virus, Advanced, Enterprise, Ultimate, or Value-added Plan edition of Security Center expires, you must renew your subscription to prevent service interruptions. If you do not renew the subscription within seven days after Security Center expires, your historical data and configurations on Security Center are automatically deleted. Security Center supports auto-renewal by month and manual renewal. This topic describes how to renew your subscription by using these methods.

Prerequisites

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

Note
  • The Protected Servers parameter specifies the total number of assets that are protected by Security Center. The assets include Alibaba Cloud Elastic Compute Service (ECS) instances and third-party servers that have the Security Center agent installed. The default value is the total number of ECS instances and third-party servers that have the Security Center agent installed within your Alibaba Cloud account. If the number of protected servers is greater than the value of the Protected Servers parameter, the Renewal button is dimmed. In this case, you must upgrade Security Center and increase the value of the Protected Servers parameter. 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 value of Protected Servers.

Expiration

Seven days before the Anti-virus, Advanced, Enterprise, Ultimate, or Value-added Plan edition expires, Security Center notifies you of the renewal by using text messages, emails, or internal messages. If you do not renew the subscription before Security Center expires, Security Center stops protecting your assets after its expiration date.

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

If you do not renew the subscription within seven days after Security Center expires, the Anti-virus, Advanced, Enterprise, Ultimate, or Value-added Plan edition is downgraded to the Basic edition. In this case, you can no longer use the features provided by the Anti-virus, Advanced, Enterprise, Ultimate, or Value-added Plan edition. You cannot view the configurations or historical data, such as alerts for distributed denial of service (DDoS) attacks. If you want to continue using the features, you must subscribe to the Anti-virus, Advanced, Enterprise, Ultimate, or Value-added Plan edition again. For more information, see Purchase Security Center.

Note The Anti-virus, Advanced, Enterprise, Ultimate, and Value-added Plan editions of Security Center use the subscription billing method. Therefore, no overdue payments occur when you use these editions of Security Center.

Manually renew the subscription

You can perform the following steps to manually renew the subscription:

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, click Overview.
  3. In the upper-right corner of the Overview tab, click Renewal.
  4. Confirm the configuration and specify the Duration parameter.
    Note When you renew the subscription, you cannot change the value of the Protected Servers or Server vCPUs parameter. If you want to increase the values of these parameters, upgrade Security Center. For more information, see Upgrade and downgrade Security Center.
  5. Read and select Security Center Terms of Service and click Buy Now.
  6. Complete the payment.

Enable auto-renewal by month

If you want to use Security Center for a long period, we recommend that you enable auto-renewal by month. After you enable auto-renewal by month, the system automatically renews the subscription before Security Center expires. You do not need to manually renew the subscription. If Security Center expires, attacks can pose threats to your services. We recommend that you enable auto-renewal by month to protect your services. If you want to modify the auto-renewal cycle, you can go to the Renewal page of the Alibaba Cloud Management Console. For more information, see the "What do I do if I want to modify the auto-renewal cycle or disable auto-renewal?" section of the FAQ topic. The following list describes the rules of auto-renewal:
  • Fees are deducted from your account balance nine days before Security Center expires. We recommend that you keep a sufficient account balance. If your subscription is due to expire the next day, you must manually renew the subscription.
  • If you manually renew the subscription before the auto-renewal takes effect, the system renews the subscription based on the updated renewal date.
  • Auto-renewal by month takes effect the day after you enable it. You can use coupons for auto-renewal.

You can perform the following steps to enable auto-renewal by month:

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, click Overview.
  3. In the upper-right corner of the Overview tab, select Automatic Renewal.
    After the settings are complete, the message in the edition information section is changed to Continuous Protection enabled. Continuous Protection enabled
