Effective April 1st, 2015, the CA/B Forum is reducing the maximum validity of OV (Organization-Validated) and DV (Domain-Validated) SSL Certificates to 36 months in order to increase SSL/TLS security. Under these guidelines, no CA or their partners should offer OV/DV SSL Certificates with a term of validity greater than 3 years. As of March 9th, 2015, Symantec will only sell OV and DV SSL Certificates with a maximum validity of 3 years. This restriction applies to new certificate issuance as well as renewals. Beginning April 1st, 2015, if you need to reissue your SSL Certificate, the maximum validity allowed will be 36 months.
