With Letsencrypt's growth, thought it would be time to revisit the SSL market share numbers at Market share quarterly trends for SSL certificate authorities, July 2017 Quarterly numbers where IdenTrust = Letsencrypt + Letsencrypt. Letsencrypt has grown to 28.3 + 0.1 = 28.4% at number #2. Comodo still grown too from 34.7% to 40.7% marketshare though they dropped from peak of 44.2 to 40.7% . Symantec dropped from 32.6% to 14.1% and GoDaddy from 14.1% to 7.5% and GlobalSign from 10.0% to 4.6% ! Once Letsencrypt starts offering Wildcard SSL certificates in 2018, pretty sure their marketshare will grow even more Still plenty of marketshare for all to grow according to Usage Statistics and Market Share of SSL Certificate Authorities for Websites, July 2017. 24.9% of web sites still do not have a SSL certificate and 34.8% have invalid domain and 1.4% have expired SSL certs. Meaning almost two-thirds of sites still aren't HTTPS (none + invalid domains).
