About ShieldFive
ShieldFive is end-to-end encrypted cloud storage. Every file and its name is encrypted in your browser before upload (post-quantum ML-KEM-1024 with XChaCha20-Poly1305 by default on the web), so ShieldFive stores only ciphertext and never holds your keys. Plans: 10 GB free with no card, monthly or yearly subscriptions, or the Lifetime Vault: 2 TB for EUR 199 paid once until 31 Oct 2026, then EUR 249, no renewals, with a 30-day refund. You can preview PDFs, images, spreadsheets and Word documents in the browser, share files with an expiry date and password, and revoke links at any time. Firms can also collect documents from clients through a request link with a PIN and checklist; clients need no account (EUR 29 per seat per month). Current limits: web app today, Android app in testing, no desktop sync client or iOS app yet. The encryption core is open source (Apache-2.0); no external security audit has been completed yet.
