Here is a brief on how 3Delight Cloud securely handles your data. Some of the strategies employed, unique to 3Delight Cloud, makes it the most secure cloud rendering service on the market.
3Delight Cloud uses TLS/SSL (256 bits encryption) when uploading your scene data to the cloud and when downloading the rendered images back to your computer. TLS/SSL is the most secured internet communication available – the same standard used by banks and other organization in need of high security.
Once your scene data reaches the cloud, it is fragmented into inaccessible smaller parts and stored using AES-256 encryption. The fragmentation is done using a proprietary process that makes it virtually impossible to rebuilt your scene without the original data on your hard drive (even if one broke the encryption to access the stored data, which in itself is impossible using current technology).
Unique to 3Delight Cloud, your images are never stored in the cloud. Not even momentarily. Here is how it works: during rendering, pixels (in buckets of 16x16) are streamed directly to your computer. It is the program that we run on your computer during rendering that receives this stream of pixels and assembles them to form the image and saves it to your hard drive (or displays it to your screen).
*And remember, these small buckets are transferred using TLS/SSL (256 encryption).
A few notes are in order here:

The consequences are limited:
