Internxt vs NordLocker

Internxt is a Spain-based cloud storage service built around zero-knowledge, client-side encryption, meaning files are encrypted on the user's device before upload so that not even Internxt can access their contents. It combines AES-256 encryption with post-quantum cryptography (Kyber-512) and offers apps for web, iOS, and Android, along with password-protected file sharing links. The service positions itself as a European alternative to large US cloud providers, citing GDPR compliance, ISO 27001:2022 certification, and an independent third-party security audit. Plans range from a free 1GB tier up to paid Essential, Premium, and Ultimate tiers offering 1TB, 3TB, and 5TB of storage respectively, available as annual subscriptions or one-time lifetime purchases, alongside separate business plans.

NordLocker provides end-to-end encrypted cloud storage using AES-256, xChaCha20-Poly1305, and Ed25519 algorithms, built on a zero-knowledge architecture so the company itself cannot access stored files. It functions as both a local encrypted vault and a syncing cloud drive, letting users secure files locally and back them up to the cloud simultaneously.

• Genuine zero-knowledge encryption model rather than just marketing language
• Lifetime plan option avoids recurring subscription costs for some users
• European jurisdiction and GDPR focus appeal to privacy-conscious users
• Open-source, auditable codebase for the security-minded

• True zero-knowledge, end-to-end encrypted storage
• Backed by the established Nord Security brand
• Functions as both local vault and cloud sync
• Free 3GB tier available

• Free tier is limited to just 1GB of storage
• Fewer third-party integrations than mainstream providers like Google Drive or Dropbox
• Zero-knowledge encryption means Internxt cannot help recover a lost account password

• Introductory pricing renews significantly higher after the first term
• No native Linux desktop client
• 3GB free tier is small compared to general-purpose cloud storage competitors
