Windows server editions typically have a ten year lifecycle. The first five years is mainstream support, the second five years are extended support. A server operating system is compliant if it is in either mainstream or extended support. Beyond this it’s necessary to purchase Extended Security Update (ESU) support.

From Microsoft:

“The Extended Security Update (ESU) program is a last resort option for customers who need to run certain legacy Microsoft products past the end of support. It includes Critical* and/or Important* security updates for a maximum of three years after the product's End of Extended Support date.

Extended Security Updates will be distributed if and when available. ESUs do not include new features, customer-requested non-security updates, or design change requests.”
