StartCom has been a key player for years in the landscape of SSL certificate providers with its ‘StartSSL’ services. They provided free SSL certificates for everybody and permitted a lot of small organizations to increase the security of their web communications. The fact that StartCom is a China-based company was, for some organizations, a good reason to flag their activities as suspicious. They also suffered from security incidents. In October 2016, Mozilla decided to remove the StartCom certificates from Firefox. Google did the same with Chrome in March 2017.
