Disclaimer: When you use these services, you are trusting them to keep your data secure and private. They encrypt your data, so it is secure while traveling across the internet and also secure while it is sitting on their servers. But because they encrypt your data for you, they can decrypt it if they so wish. Or if they are ordered to by the local government. Or if some powerful intelligence agency “convinces” them that it is in their best interest to do so.​

Today, NordLocker retains all its original capabilities, and adds its own encrypted cloud storage system as well. Why the change? As Oliver Noble, an encryption specialist at NordLocker explains,

NordLocker took a challenge to revise and turn round existing cloud storage practices. Encrypting files first and uploading them to the cloud of the same provider helps to avoid the involvement of third-party vendors. All that can be done with a single move of drag and drop.

With 3 GB of cloud storage now included in the Free NordLocker plan, and 500 GB included in the paid Premium plan, NordLocker is positioned to go head-to-head with the leading cloud storage services, rather than just relying on them for storage.

+ Pros

Clean, drag-and-drop design;
Strong, end-to-end (zero-knowledge) encryption;
Cloud and desktop encrypted file storage;
Same platform and cross-platform sync;
No file size or type restrictions;
HIPAA and GDPR-compliant;
Free, Premium, and Business plans available;
Open, edit, and save files directly in lockers;
New, lower price;
Numerous payment options;
30 days, money-back guarantee.

– Cons

No Linux or mobile clients (yet).
