We use 128-bit AES, moving up to 256 bit AES (military grade protection), and maxing out with 448-bit Blowfish encryption. 

In addition, Atera does not keep a copy of the encryption key. This adds an extra level of data protection for our customers.

Note: Online Backup (Datashield) is a legacy product only available to older Atera accounts. For newer backup solutions, check this page.
