Loaded and locked: 3 seriously secure cloud storage services

Sarah Jacobsson Purewal | March 7, 2014
For the truly paranoid, storage that's encrypted from start to finish and ... Loaded and locked: 3 seriously secure cloud storage services.

Cloud storage services such as Dropbox, Google Drive, and SugarSync are convenient, efficient—and notoriously insecure. Files are rarely encrypted, data transfer is typically not protected, and companies are usually able to access your files (even if they state they won't, they may be legally compelled to do so).

Documents such as business plans or other sensitive files (say, a copy of your birth certificate) should be protected. You can utilize a special, ultra-secure provider such as Wuala or Tresorit, or you can encrypt files yourself before uploading them to larger storage services, such as Dropbox.

Wuala
Price:5GB Free; Plans starting from 20GB for $4/month
Platforms: Windows, Linux, iOS, Android

Wuala is a secure cloud storage service offered by storage company LaCie. This service differs from mainstream cloud storage providers in two ways:

Client-side encryption of files: All of your files are encrypted locally on your device before being sent to the cloud, which ensures that even on a non-encrypted transfer, no readable data would leak out. This process is more secure than a secure transfer, mainly because it means that nobody except you ever has access to your data.

Zero-knowledge password policy: Only you know your password, and therefore only you can access your account. Wuala's employees cannot see your password, nor can they see your data except in raw form (how many files you have and how much storage space they take up). So even if the government came knocking on Wuala's door and asked them to turn over your files, they simply wouldn't be able to do so. Nor will you be able to get to your stuff if you forget your password, so keep it carefully.

Security aside, Wuala operates like the cloud storage services you're used to. Simply download Wuala's application and the service will install a special sync folder to your device, where you can drag and drop files to store both locally and in the cloud. Wuala also offers backup and versioning, which means you'll be able to access previous versions of files or restore files should you accidentally delete them. Like other cloud storage providers, Wuala offers 5GB of storage for free. Pricing plans start at 20GB for $4 per month.

Tresorit
Price: 5GB Free; Plans starting from 100GB for $7/month
Platforms:Windows, Mac OS X, iOS, Android

Tresorit is a cloud storage provider that claims to offer "a truly secure cloud storage service." Security features include client-side encryption, secure data transfer, and secure data centers that are equipped with physical security measures against intrusion as well as uninterruptible power and backup systems.

Like Wuala, Tresorit encrypts your data on your local machine to help ensure that your files are protected at all times. It, too, practices a zero-knowledge password policy, which means that nobody in the company can ever access your password or decryption keys. Of course, the drawback of such a policy is that if you forget your password, you're basically out of luck (you'll have to create a new account, and you'll lose all of your data in the cloud).
