Internxt is a cloud storage service built on open-source principles, offering end-to-end encryption so that your files remain encrypted both in transit and at rest. It's designed for privacy-conscious users who want to avoid storing sensitive documents or media on mainstream providers like Google Drive or Dropbox. The service appeals to individuals and small teams who value transparency—the company publishes its encryption code for public review—and prefer a smaller, privacy-focused vendor over a household name.
Most users bring Internxt into their workflow when they need encrypted backups of personal files, want to keep work documents away from corporate surveillance, or simply distrust centralized American cloud providers. It's often picked by journalists, activists, or anyone handling confidential materials. The typical buyer is willing to trade slightly less polish or integration depth for the certainty that their storage backend isn't scanning their content. If you're choosing between Internxt and other encrypted storage options, your main trade-off is usually between price, feature breadth, ease of use, and the security guarantees each vendor makes.

Cryptomator is the best open-source choice if you want to encrypt files on any cloud provider you control. Proton Drive and Tresorit offer zero-knowledge storage similar to Internxt but with different pricing and ease-of-use trade-offs. Your choice depends on whether you need extreme transparency (Cryptomator), a polished paid service (Proton Drive), or maximum control of your encryption keys (Tresorit).
Cryptomator is completely free and open-source. Proton Drive, MEGA, and Filen all offer free tiers with encrypted storage, though they come with smaller free allowances and limited features compared to their paid plans.
MEGA and pCloud offer the cheapest paid storage per gigabyte, but neither emphasizes zero-knowledge architecture as heavily as Internxt or Tresorit. If cost is your priority over maximum encryption guarantees, MEGA is often the lowest option for large storage.
Cryptomator lets you encrypt files and store them on Dropbox, Google Drive, or any provider you want. Sync.com, Box, and Dropbox don't offer client-side encryption by default—you'd need Cryptomator as an overlay. Proton Drive, Tresorit, Filen, and Internxt all manage their own storage infrastructure.
Check whether the service uses zero-knowledge encryption so the provider can't read your files, whether the code is open-source or audited by third parties, what the storage limits and pricing tiers are, whether it supports file sharing and recovery keys, and whether it works across desktop, mobile, and web platforms you need.
Most do: Proton Drive, Tresorit, Filen, pCloud, Sync.com, MEGA, Box, and Dropbox all have mobile and desktop apps. Cryptomator requires more manual setup on mobile but works on iOS and Android.
Proton Drive, Tresorit, and Filen have built-in file sharing with link generation and expiration controls. Cryptomator requires more setup but lets you encrypt before sharing via any method. Internxt, MEGA, and pCloud also support sharing but with varying levels of ease.
Services like Sync.com and pCloud let you sync files locally so they're available offline. Cryptomator works entirely offline once you set it up. Web-only or cloud-first services like Proton Drive and Google Drive require internet to upload new files, though you can view previously synced files offline on some apps.
