Since we already offer global scalability and continuous deployments with Heroku Enterprise, it is easy for us to roll out the benefits of HTTPS to all our clients. We believe all online services should use HTTPS. With the high usage of unencrypted open WiFi hotspots and the global share of sites using HTTPS on the rise, now is the time to migrate all sites. This will become the default way of accessing any web-services in the future, and we want to support this by making the migration easy and free for all our clients.
Benefits of HTTPS in a nutshell:
Keeps the content of all pages confidential Guarantees content integrity so that nobody can tamper with the content Provides better privacy for customers Prevents attackers from impersonating client sites Can improve search rankings Allows migration to HTTP/2
