Using SSL at Umbler
Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser.
When to use SSL?
SSL secures millions of peoples’ data on the Internet every day, especially during online transactions or when transmitting confidential information. Internet users have come to associate their online security with the lock icon that comes with an SSL-secured website or green address bar that comes with an Extended Validation SSL-secured website. SSL-secured websites also begin with https rather than http.
SSL at Umbler
Umbler works only with SNI certificates, that are certificates emitted for the domain and not for the server or IP. This allows the certificate to be used in any provider, regardless of the server or IP address.
SSL using Let´s Encrypt
Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. It is a service provided by the Internet Security Research Group (ISRG).
Let’s Encrypt gives people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, for free, in the most user-friendly way possibe
The certificate is valid for 90 days, but it'll be renewed automatically at Umbler.
In order to activate Let's Encrypt certificate the domain DNS's records have to be pointed at Umbler, by either using our NameServers or pointing the A record to the IP of the website hosted at Umbler.
Under the selected Domain, go to Website > Settings > SSL and choose Enable Let's Encrypt free certificate.
Check that your website and DNS configurations fulfill the requirements and click on Enable:

Now CloudFlare is configured and activated as your website's CDN. Go to the Crypto tab, on the upper menu to activate SSL:
