What is ShieldFive?
ShieldFive is end-to-end encrypted cloud storage. Every file and its name is encrypted in your browser before upload, by default with post-quantum ML-KEM-1024 and XChaCha20-Poly1305, so ShieldFive stores only ciphertext and never holds your keys.
Start with 5 GB free and no card, pay monthly or yearly, or buy the Lifetime Vault: 2 TB for €199 paid once, no renewals, with a 30-day refund. Preview PDFs, images, spreadsheets and Word documents in the browser without downloading them, and share files through links with an expiry date and password. Firms can also collect documents from clients through one request link that needs no client account (€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.

ShieldFive FAQ
How does ShieldFive simplify collecting documents from clients?
ShieldFive lets a firm send a single link with a checklist of required documents. The client opens the link in any browser, enters a PIN, and uploads files from a phone or computer without creating an account. Each file and its name are encrypted in the client's browser to the firm's keys, so ShieldFive never sees the plaintext.
How does ShieldFive differ from Tresorit in terms of client onboarding?
Unlike Tresorit, ShieldFive does not require recipients to create an account or install software. Clients simply open a link in any browser, enter a PIN, and upload files, with encryption happening in their browser before any data reaches ShieldFive's servers.
Which teams benefit most from ShieldFive's no-account upload feature?
Teams such as law firms, financial advisors, and healthcare providers benefit most because they can securely collect sensitive documents from clients without requiring the client to sign up or learn a new tool. The client only needs a browser and the PIN, making the process frictionless and secure.
What kind of workflows does ShieldFive's open-source CLI support?
ShieldFive's open-source CLI supports automated document sharing and encryption workflows, such as batch uploading files from scripts or integrating secure file transfer into existing pipelines. It provides the same end-to-end encryption as the web interface, allowing teams to programmatically manage encrypted file operations.
How is ShieldFive priced?
ShieldFive is available on a free tier, with paid plans for more usage and features. The free tier allows users to try the service, while paid plans unlock higher storage limits, additional sharing capabilities, or advanced administrative controls.
Why does ShieldFive use ML-KEM-1024 and X25519 for encryption?
ShieldFive uses ML-KEM-1024 with X25519 for key encapsulation to provide post-quantum security, ensuring that encrypted files remain protected even against future quantum computing attacks. The combination with XChaCha20-Poly1305 for symmetric encryption delivers strong, efficient confidentiality and integrity for each file.
Can ShieldFive be used to securely store files for personal use?
Yes, ShieldFive includes an end-to-end encrypted vault where users can store files securely. Files are encrypted with the user's keys before upload, and ShieldFive stores only ciphertext, never holding the decryption keys, so only the user can access their vault contents.
