Curated List of Encrypted Cloud Storage Services
Today, we’ll take a look at several cloud storage services that support client-side encryption. This feature is crucial for maintaining the confidentiality and overall security of your data. Major services like Google Drive, DropBox, OneDrive, and Yandex Disk do not offer client-side encryption. However, the following services do:
1) Mega
Mega (MEGA Encrypted Global Access) is an ambitious cloud file-sharing service founded by Kim Dotcom, the creator of the legendary Megaupload. Mega encrypts all content directly in your browser using the AES algorithm. Users can share files with each other in encrypted form, and all data is stored in the cloud. Access keys are not made public; instead, they are shared via a Friend-to-Friend scheme between trusted users.
- Free storage space: 50 GB
2) pCloud
pCloud is a secure cloud storage solution for your files. Security is ensured in two ways: first, all information is transmitted to pCloud servers via TLS/SSL protocols and is copied to at least three servers in different locations within a highly protected data center. Second, you can subscribe to pCloud Crypto ($3.99/month) to take advantage of bulletproof client-side encryption with a user-friendly interface.
- Free storage space: 20 GB
3) iDrive
iDrive is an ideal tool for online backups with a high level of privacy. If you want to keep copies of important documents on a cloud server, iDrive is what you need. It’s easy to use: download the iDrive software, launch the app, and select folders to sync. You can back up data from your PC, Mac, iPhone, iPad, and Android devices all under one account. iDrive offers a high level of data security: files are transferred and stored with 256-bit AES encryption using a user-defined key that is never stored on the servers.
- Free storage space: 5 GB
4) SpiderOak
SpiderOak is considered one of the most secure cloud storage services (even endorsed by Edward Snowden). The developers assure that your account password is never transmitted anywhere. Upon your first login, a special key is created, which grants the desktop client access to your cloud storage.
- Free storage space: 10 GB
The last service on this list is the most popular but is very limited in features on the free plan. Be careful when choosing a cloud storage service to ensure it meets your privacy and security needs.
