The service that you purchased in Security Center is valid within a specific period of time. You must renew the service within the validity period. Otherwise, the service will become unavailable.
One week before your Security Center subscription expires, Security Center sends you a message reminding you to renew your subscription. If you do not renew your subscription before it expires, your assets are no longer protected by Security Center starting from the first day after the expiration date.
For three days after the expiration date, Security Center retains all your configurations and data, such as your asset groups, tags, quarantined files, vulnerability whitelist, baseline check policies and baseline check whitelist, and asset fingerprints. You must renew your Security Center subscription within the three days to retain your configurations and data.
If you do not renew your subscription within three days of your Security Center subscription expiration date, your Security Center configurations and data are removed. You must purchase a new Security Center Advanced or Enterprise Edition subscription to resume use of Security Center.
