# SSL Certificates
We want to ensure that our user's data is encrypted during transit and that the data they may provide is sent securely. The HTTPS-Only Standard (opens new window) provides a great, and much more detailed, description of the reasoning behind this.
This has become much easier with Let's Encrypt (opens new window), which provides a free to use, automatic and secure certificate authority. It's integrated with Heroku, which allows us to use their Automated Certificate Management (opens new window) feature.
When we need wildcard certificates (e.g.: when we want to use the same certificate across www.
, staging.
, etc.), or those with advanced features, we use GoDaddy (opens new window).
