Your files. Your keys.
Encrypted Vault is zero-knowledge cloud storage from PremierVPN. Files are encrypted in your browser before they ever leave your device. We can't read them. Nobody can — except you.
1 GB included with all PremierVPN service plans. Upgrade for more.
Encryption that even we can't undo
Your files are encrypted in your browser using a passphrase that never leaves your device. Not even PremierVPN staff can access your data.
Set a passphrase
Choose a strong vault passphrase. It derives your encryption key using PBKDF2 with 100,000 iterations. This never leaves your browser.
Files encrypt locally
When you upload, your browser encrypts the file with AES-256-GCM before it leaves your device. The original file never touches our servers.
Stored encrypted
The encrypted blob is stored on infrastructure with server-side encryption on top. Double encrypted — even a physical breach reveals nothing.
Decrypt on download
When you download, the encrypted blob streams to your browser, decrypts locally with your passphrase, and saves the original file. End to end.
Privacy by design, not by promise
Zero-Knowledge Encryption
Files are encrypted in your browser before upload. We store only encrypted blobs. Without your passphrase, the data is meaningless — even to us.
AES-256-GCM
The same encryption standard used by governments and military. 256-bit keys derived via PBKDF2 with 100,000 iterations. Authenticated encryption prevents tampering.
Direct Upload
Files go directly from your browser to encrypted storage. They never pass through our application servers, eliminating an entire class of vulnerabilities.
Secure Sharing
Share files via password-protected links with download limits and expiry times. Recipients decrypt in their browser — no account needed. Passphrase shared separately.
Folders & Organisation
Create folders to organise your files. Star important documents for quick access. A clean, fast file manager built into the PremierVPN portal.
If You Forget, It's Gone
We don't store your passphrase or encryption keys. If you forget your passphrase, nobody — including us — can recover your files. That's real zero-knowledge.
Dead Man's Switch
If you don't log in for a configurable period, your vault automatically destroys all files or shares them with a trusted contact. No other consumer storage service offers this.
Configurable Countdown
Set the inactivity period from 7 days to a full year. Every time you access your vault, the timer resets automatically.
Destroy or Share
Choose to permanently wipe everything, or share your files with a designated emergency contact. They receive download links but still need your passphrase to decrypt.
7-Day Warning
You receive an email warning 7 days before the switch triggers. One login or one click on "I'm Still Here" resets everything.
Built for journalists protecting sources, activists in hostile environments, and anyone who needs a failsafe. If something happens to you, your data either vanishes or reaches the right person.
Protection beyond encryption
Encryption keeps your files private. These features keep you safe when things go wrong.
Geo-Destruction Rules
Define which countries are allowed to access your vault. If someone logs in from an unapproved country, your files are automatically locked or destroyed. Protects against account compromise from foreign state actors.
Timed File Expiry
Set an auto-destruct date on any file. Upload a contract, set it to delete in 90 days. When the time comes, the encrypted blob is permanently wiped from storage. Not just hidden — actually destroyed.
Encrypted File Names
File names are encrypted client-side before upload, just like the files themselves. Our servers store only encrypted metadata. We don't just protect your files — we don't even know what they're called.
What we see vs. what we don't

- · Your vault passphrase
- · Your encryption keys
- · Decrypted data at any point
