Let's Encrypt is a new Certificate Authority. It will provide free X509 certificates in an automated way, with close to no deployment overhead. Currently, requesting and deploying X509 certificates is a tedious and costly process - both in terms of vendor and labor costs. Our studies show that it often takes between 1 to 3 hours to go thorough the entire process of setting up HTTPs on a webserver. Let's Encrypt will reduce that time to a matter of minutes for the initial setup, and mere seconds for renewals.
