This chart represents the percentage of requests to Google's servers that used encrypted connections.
This is an approximate number that represents most of Google traffic.
This is an approximate number that represents most of Google traffic for the given product.
We are working to implement HTTPS across all of our products. In March 2014, we announced the use of HTTPS-only for Gmail. We continue to work through the technical barriers that make it more difficult to support encryption on some of our products.
Encrypted traffic varies by country. This chart represents the top 10 countries by percent of traffic that Google receives. The variation between countries is due to a variety of factors, including the types of devices in use in that country, as well as the availability of software that can support modern TLS.
Some older devices cannot support modern encryption, standards or protocols. The vast majority of unencrypted end user traffic originating from a set of surveyed Google services comes from mobile devices. Unfortunately, these devices may no longer be updated and may never support encryption.
Unencrypted user traffic by device type
Several technical and political challenges stand in the way of attaining full traffic encryption:
- Older hardware and software do not support modern encryption technologies.
- Certain countries and organizations block or otherwise degrade HTTPS traffic.
- Some organizations do not have the desire or technical resources to implement HTTPS.
- Certificate management can be challenging for products like Blogger, where a user's non-Google domain can be used.
