NordLocker

NordLocker, from the team behind NordVPN, is an encryption tool with secure cloud backup. It first encrypts files locally using zero-knowledge cryptography before optionally uploading them to Nord's cloud. It's designed for ease of use, allowing users to drag-and-drop files into a secure locker. It enables secure sharing of encrypted files.

Based in privacy-friendly Panama, it benefits from a trusted security brand. Its model is more encryption-first than traditional sync-and-share, making it ideal for users who prioritize locking down specific sensitive files before they ever hit the cloud.
