If you planned to purchase an SSL certificate for three years, we advise you to hurry. Soon, the certifying centers will stop issuing three-year SSL certificates of all types. After February 20, 2018, SSL will not be sold for three years from GeoTrust, RapidSSL, Symantec and Thawte. Since March 1, it will not be possible to buy certificates for three years from Comodo. All active three-year SSL certificates will work after March 1.
