- Before files leave your computer or mobile device they are protected using a first layer of Advanced Encryption Standard (AES) encryption, the same encryption used by banks and military organizations.
- Files are transferred to our secure cloud using a Secure Sockets Layer (SSL) connection that employs a second layer of AES encryption.
- Once files reach our data centers, your data is protected with a third layer of AES encryption.
