A major browser vendor recently announced that as of Sept. 1, 2020 it will no longer consider as valid and secure SSL certificates issued after this date with validity of more than 398 days (equal to one year + 1 month). For this reason, from August 3, 2020, SSL certificates issued by Actalis will have a maximum validity of one year, net of the notice period for renewal. Until August 3, 2020, however, SSL certificates with 24 months validity can still be purchased and activated as those activated before this date will still be considered valid until their expiry.
