From August 19th 2020, SECTIGO issues SSL certificates with a maximum lifetime of 398 days (13 months) as specified by CA/Browser consortium. SSL certificates with a longer lifetime must be re-issued annually (free of charge). You'll receive reminders via e-mail. SSL certificates issued before August 19th 2020 remain valid until their planned expiry date. Code Signing & S/MIME certificates are not affected and remain valid until their planned expiry date.
Multi-Domain (SAN) certificates: will "www.domain.com" and "domain.com" count as two SAN entries?
When using multi-domain SSL certificates www and non-www versions of the domain name are considered to be different domain names, and will require separate SAN (addon) slots in the certificate.
However, when using GeoTrust/Symantec/Thawte certificates you can get a free SAN of domain.com if the Common Name of the SSL is www.domain.com, so the non-www version of the common name will be secured by the SSL for free.SAN Example for COMODO PositiveSSL Multi-Domain:
CSR Slot #1: www.domain1.com
SAN Slot #2: domain1.com
SAN Slot #3: abc.domain1.comSAN Slot #4: xyz.domain1.com
SAN Slot #5: www.domain2.com
SAN Slot #6: domain2.com
SAN Example for GEOTRUST True BusinessID:
CSR Slot #1: www.domain1.com
(as this is the main domain and www.domain1.com was specifiec inside CSR, domain1.com will automatically be included for GEOTRUST True BusinessID!)
SAN Slot #2: abc.domain1.com
SAN Slot #3: xyz.domain1.com
SAN Slot #4: www.domain2.com
SAN Slot #5: domain2.com
