What Makes Cloud Storage the Best for Lawyers?

Zero-knowledge encryption is a type of encryption where only the account holder has access to their encryption keys. Your provider doesn’t have access to them, and your keys aren’t stored anywhere on their servers. The downside is that if you lose your keys, you lose your files, so you may want to check out our password creation tips to prevent that from happening.

In-transit encryption is when files stay encrypted while being uploaded to the internet or downloaded to a local machine. In other words: this means that your data is “scrambled” when on its way to or from your computer to the service provider’s data center. If someone was to intercept your files, they would get a jumbled file that is essentially worthless.

However, both zero-knowledge and in-transit encryption are worthless if they’re secured with out of date encryption technologies. Make sure that your cloud storage uses at least 256-bit AES encryption to secure your files. To this day, 256-bit AES has never been cracked.

Two-factor authentication requires two things to authenticate a sign-in: something you know (a password) and something you own. “Something you own” can be a smartphone running an authenticator app or a digital key fob. This adds an extra level of security to your account because even if someone has your password, they can’t access your account without physical access to your two-factor device.

Lawyers who work with doctors or touch medical records must use a HIPAA compliant cloud storage solution if based in the United States. Being HIPAA compliant means that the cloud storage company has taken government approved precautions in regards to protecting their servers physically and digitally.

The easiest way to find out if a cloud storage provider is HIPAA compliant is by googling the firm’s name followed by “business associates agreement.” This agreement is provided to HIPAA-required companies and acts as verification that their cloud storage provider (or other healthcare services company) is HIPAA compliant. All the below providers are HIPAA certified.

Finally, take cost and storage space into consideration when shopping among our cloud storage reviews. Each cloud storage company has a different price-to-storage ratio, so assess your storage needs and buy a plan that both fits your budget and can store all your files..

Best Cloud Storage for Lawyers: Sync.com

Sync.com is our top pick for cloud storage solutions for lawyers. It offers well-implemented zero-knowledge encryption, in-transit encryption and two-factor authentication at no extra charge.

Sync.com Review – Web Panel

The service uses top-of-the-line encryption technologies, featuring 2048-bit RSA encryption keys and 256-bit AES encryption on the files themselves. And since only you hold your encryption keys, your files nearly impossible to steal, even if Sync.com’s servers are compromised.

These security features come with one downside: reduced performance. File retrieval times suffer on Sync.com due to the fact that each file has to be decrypted on the fly. Photos and other files protected with zero-knowledge encryption cannot be previewed online as these files must be decrypted on your desktop before they can be opened.

See our Sync.com review for more info.

Other Reasons Why We Like Sync.com

Sync.com is an inexpensive cloud storage solution. Individual lawyers can sign up for the Business Solo plan that costs $8 per month and is billed annually. This package includes 2TB of cloud storage and all of the security features mentioned earlier.

If you’re unsure about purchasing a Sync.com license, sign up for one of its free 5GB accounts (there is a reason it wins in our best free cloud storage article). Additionally, Sync.com’s business plans have a 30-day money-back guarantee, so there’s no harm in testing.

Additionally, all file transfers to and from SpiderOak’s servers are encrypted point-to-point.

SpiderOak secures backups using the latest encryption technology. The cloud storage provider takes a layered approach to encryption and uses a combination of the 2048-bit RSA and 256-bit AES algorithms. Read our SpiderOak review for more information.

Like other solutions on this list, Tresorit secures on all files with zero-knowledge encryption and accounts can be secured with two-factor authentication. All files stored on Tresorit are protected with 256-bit AES encryption, so your files are worthless to anyone without the encryption key.

  1. I want to know which cloud service has the best usability and functionality. Since I work on multiple documents during the day, I want an easy way to sync without having to do giant folders or have all my individual documents listed separately.

  2. I use Apple computers, ipads and MacBook Pro. I have to decide on which cloud service to use to save all my client documents (discovery, pleadings, motions, notes, etc). I’ve been using Google Drive but it is not good. What cloud service do you suggest I use instead on Google Drive?

    1. Cloudwards.net

      Thanks for the question, Ralph. There are a few routes you can take. If Google Drive appeals to you, you can take care of the privacy issues by using Boxcryptor, which lets you encrypt any files you upload to Google Drive. Or, if you’d rather not bother, Sync.com, Tresorit and pCloud all provide built-in zero-knowledge encryption, meaning nobody but you can decrypt and read your files. Of the three, Sync.com is the best deal (2TB for $8 a month), while pCloud is the most flexible since it allows for file previews via your web-browser and has a network drive feature. With pCloud, you’ll need to purchase a separate add-on called Crypto, however, if you want the zero-knowledge encryption benefit. Tresorit is the most expensive by far, but probably the most secure overall, too.

      Hope that helps. Best, Joe.

  3. I create documents in wordperfect. Is any one cloud service better than the other for storaging and/or retrieving wordperfect documents

  4. so right now i have the whole firm on local hard drives..its about 1 tb of info in all kinds of formats wpd, office, adobe, jpeg..how easy is the initial upload for these services..does it take days and days? when its done, will it mirror my file structure of the uploaded pc?
