Hi. Does we have to renew this add on license yearly?

Hello Tasya, you do. Cyren Premium Antispam, and all of the SmarterTools add-ons, are offered as 12-month subscriptions. Because they are only available when you have active protection, they will share the same expiration date as your Upgrade Protection.
