Expand Amazon S3 Encryption Options

Make AWS S3 encryption better to improve your Amazon S3 security with CloudMounter. This software lets you mount Amazon cloud drive on your machine so you can browse through it as if it were just another local or network drive.
Yoo-hoo! CloudMounter runs natively on Mac computers with Apple silicon: M1 and M2 series!

Use Amazon encryption for better security

In case of S3 server side encryption AWS uses its own encryption key and removes it from the memory once the Amazon cloud encryption is done. When a client provides the decryption key, the encrypted symmetric key is retrieved and decrypted with client’s real key, then it is used for decrypting the data. Since the symmetric key is stored on AWS side, the client does not fully control the keys and their use. The best option to manage your data on Amazon S3 and for data encryption is to get CloudMounter.

Mount as a Disk

CloudMounter owners do not have to duplicate data locally and online, thus saving precious space on their hard drive.

Cloud security

Encryption proves to be very efficient for file transfer protection. Increase your Amazon Cloud security with CloudMounter.
