8 best end-to-end encrypted cloud storage services

As the cloud has become more and more common in everyday use, cybercriminals have begun to shift their focus to infiltrating this type of service.

For that reason, it is necessary to encrypt all data stored in your cloud. Whether you're running a business or simply using it for personal use, it's paramount to take this first line of defense into account.

So what are the most secure cloud storage service providers today? Here are the top 8 choices that TipsMake would recommend to readers.

1. IDrive

This E2EE cloud storage service is more like a backup solution. This is not a criticism of IDrive's functions but rather a note towards the hybrid approach to cloud storage. IDrive's data servers are in the US, which means they're governed by US law, so despite their excellent privacy policies, they're still part of the Five Eyes network.

A unique feature of this E2EE cloud storage service is that, if needed, you can request a physical copy of your data. After you pay, IDrive will mail you a physical hard drive to back up or restore your data before sending it back.

2. Sync

Based in Canada (another Five Eyes country), Sync is one of the best priced cloud storage services. In addition, Sync is a Zero-knowledge E2EE storage service (the cloud company will not have access to your encryption keys or data), PIPEDA, GDPR, and HIPAA compliant. It is worth noting that only the paid plans offer E2EE services.

The sync feature is also ideal for users who work with large files, as it has no file size or transfer limitations.

3. Icedrive

Icedrive is one of the best and better priced E2EE cloud storage services. Founded in 2019, its data servers are located in Wales in the United Kingdom. Unlike most encrypted hosting services, it does not use standard AES encryption but uses the lesser known Twofish encryption algorithm.

There are 3 main disadvantages of Icedrive: Data transfer will limit upload and download bandwidth performance, there is no two-factor authentication feature, and there are very few plans to choose from. These limitations are not severe as this is common for a new company to gradually expand services and functionality like this.

4. Internet

Another very new E2EE cloud storage provider is Internxt. The company was founded in 2020 and launched in Spain. It currently promises users that it will be the best privacy-preserving cloud service on the market. Internxt is committed to doing this by following a decentralized and distributed data storage policy model. It is also one of the few companies using Blockchain technology.

Unlike Icedrive, Internxy is based on traditional AES encryption algorithms, which are open source so users can improve or modify them.

5. MEGA

Like Internxt, MEGA claims to be "the only company that promises to put privacy first". MEGA is based in New Zealand and the unique feature of the service is that it offers E2EE Zero-knowledge for free and premium accounts (the paid option is also surprisingly cheap). Very few companies offer free E2EE cloud storage solutions.

6. pCloud

One of the most famous E2EE Zero-knowledge cloud storage service providers is pCloud. It is based in Switzerland, which, along with Germany, has some of the strongest privacy laws.

The best feature of pCloud is that it allows you to view all your files without downloading them. And it doesn't limit individual file sizes, which works well if you deal with a lot of large files. One downside and the reason that pCloud is not at the top of the list is that it only offers E2EE as an add-on.

pCloud has a great encryption algorithm. The service uses RSA for user private encryption keys and AES for private file and folder encryption keys. Other significant advantages of pCloud are that it allows you to choose where to store your data, has no file size limit, and is an extremely user-friendly cloud service.

7. Tresorit

Tresorit, pCloud's biggest competitor, is also headquartered in Switzerland. The main difference between the two is that Tresorit is a bit more enterprise-oriented (meaning suitable for those looking for a multi-user cloud service).

In addition, Tresorit is GDPR and HIPAA compliant, as well as fully compliant with Swiss privacy laws. As with pCloud, it allows users and businesses to choose where their data resides. Tresorit's main drawback is that it's expensive because it's primarily aimed at businesses.

8. SpiderOak

SpiderOak is similar to IDrive in that it is more of a backup solution than a traditional cloud storage service. However, it also provides secure collaboration, communication features, and file-sharing and synchronization tools. In a word, SpiderOak is a regular online storage (old version of the cloud) that uses Zero-knowledge encryption.

There are E2EE cloud storage services for every need. These can be free options, for businesses, or hosted in a European Union country. Even so, you'll probably prefer zero-knowledge providers. Now you know the cloud storage services with the best security. You can find a number of other services to better suit your needs.
