With cyberattacks on the rise, file encryption has become a necessary cloud storage security measure. If you want to protect your data from malicious parties, you need a service offering cutting-edge security protocols.Most cloud solutions promise outstanding protection, but only a handful deliver it. Big Tech providers typically oversell their encryption standards, making users believe they have more privacy than they actually do.To help you safeguard your files, this guide will explain different encryption types and show you which one offers the most protection. You’ll also see some of the most popular providers offering cloud storage with encryption so that you can find the right option.

Not all cloud storage encryption standards are equal

Most cloud providers offer two encryption types:
  • Encryption at rest—protects your files and data while they’re idle on the cloud
  • Encryption in transit—shields your data while it’s traveling between endpoints
At first glance, a cloud provider offering both types seems to cover all ground. If your files are protected while sitting on the servers and traveling between them, it’s normal to assume there are no vulnerabilities an attacker could exploit.This is the logic most providers use to market their solutions as completely safe. In reality, there are two major issues with this level of protection:
  1. Weak protocols
  2. Encryption key ownership
Data in transit is typically encrypted using the TLS (Transport Layer Security) protocol. This encryption standard is outdated and full of vulnerabilities, so it doesn’t offer enough security for shared data.Even if it did, your files are still encrypted on the provider’s server using their key. Whoever owns the key has unrestricted access to plaintext data, so you get no privacy from the provider. They can access unencrypted copies of your files, which is quite invasive.An even bigger threat is a server breach. If an attacker penetrates the server’s defenses, they can steal encryption keys and gain access to all your data.This is why you shouldn’t consider every cloud provider promising to keep your files encrypted. You must assess their measures and go with a service offering the only secure standard—end-to-end encryption.

The importance of using end-to-end encrypted cloud services

End-to-end encryption (E2EE) protects files before they leave your device. Here’s how it works:
  1. The encryption key is created by the user and stored locally
  2. Files are encrypted before being uploaded
  3. Your data reaches the cloud server and is stored on it in the encrypted form
This mechanism offers numerous benefits you don’t get with standard encryption. As your device creates and stores the encryption key, the cloud provider can’t see your files in plaintext—only the encrypted data. You get complete privacy and confidentiality.If a malicious party breaches the server, they’ll also see ciphertext instead of the original data. The decryption key remains safely stored on the user’s device, so as long as they keep it secure, nobody can get ahold of the key.The above benefits make it clear that end-to-end encryption is the best way to stay safe in a cloud environment, so narrow your search to the providers supporting it.

Best cloud storage with encryption—top three providers reviewed

Several privacy-first cloud providers support end-to-end encryption, giving you peace of mind when storing files on their drive:
  1. Proton Drive
  2. NordLocker
  3. Skiff Drive
Offering E2EE doesn’t make these options equally effective, as you’ll see in the below breakdowns of each.

Proton Drive

Source: ProtonProton Drive is a secure cloud solution protected by stringent Swiss privacy laws. It offers various privacy and security measures, but the storage size is slightly disappointing compared to the competition.


Proton Drive offers a free plan and two paid tiers:
  1. Drive Plus—$4.99 per month ($3.99 per month billed annually)
  2. Proton Unlimited—$11.99 per month ($9.99 per month billed annually)

Pros and cons

Proton is best known for its secure email service, Proton Mail. After the platform’s success, the provider launched a popular VPN service alongside a cloud solution. All of its platforms are protected with end-to-end encryption, so you get excellent privacy compared to a typical Big Tech solution.Proton Drive supports all file types and extends their protection to sharing links. It features a clean user interface, so navigation is smooth and intuitive.Despite these benefits, Proton might not be the best choice for several reasons. It uses PGP (Pretty Good Privacy) for end-to-end encryption, which is an outdated standard. It has been tied to significant vulnerabilities, so several providers have already moved away from it.Another major drawback is limited storage. You only get up to 1 GB of free storage, with 500 MB available out of the box. You can get the rest by completing simple actions like uploading files, which feels unnecessarily complicated for such low storage.Even the Proton Unlimited tier doesn’t live up to its name, as it caps at 500 GB. You do get access to premium versions of Proton VPN, Calendar, and Mail, but this might not make up for the limited storage.

Source: NordLockerNordLocker is a solid solution if you’ll use a cloud service for archives and backups. It’s not as feature-rich as most competitors, but it still offers enough security to be worth considering if privacy is your main concern.


NordLocker offers a free plan and various paid tiers for individual and business users:
  1. Individual plans:
    1. Personal—$8.48 per month ($3.17 per month billed annually)
    2. Personal Plus—$21.22 per month ($7.42 per month billed annually)
  2. Business plans:
    1. Business—$12.99/user per month ($8.99 per month billed annually)
    2. Business Plus—$18.99/user per month ($14.99 per month billed annually)
    3. Custom—Pricing tailored to chosen storage and features

Pros and cons

NordLocker uses zero-knowledge end-to-end encryption, giving users high levels of security and privacy. With servers in various locations, it lets users choose where their data will be stored.The platform has a unique selling point—besides providing encrypted cloud storage, it lets users encrypt files in their local storage. If someone uses your computer, they can see the encrypted folder but can’t access it or see any details on the files inside.NordLocker is compliant with several important regulations, including HIPAA and GDPR. It’s great for storing sensitive data and ensuring there’s no misuse of personal information.If you need a cloud solution to collaborate on projects, NordLocker won’t be your top choice. It doesn’t feature any editing, collaboration, or even file-sharing features. Pair this with the lack of iOS and Android apps, and you can see why this option isn’t ideal for work, especially in a remote setting.Although it’s more generous than Proton storage-wise, NordLocker is still slightly limited. You get 3 GB with the free plan and 500 GB/2 TB with paid personal and business tiers. Considering the relatively high price, the value for money isn’t great unless you commit to an annual subscription.
