What You Need to Get Started with FISSM

Google Drive

OneDrive

Padlokk needs no cloud provider.

Why Fissm is Different

Traditional cloud storage puts all your eggs in one basket. We revolutionize security by distributing your encrypted data.

Military-Grade Encryption

AES-GCM-256 encryption with unique passwords for every file. Your data is encrypted in your browser before it ever leaves your device.

Distributed Storage (FISSM)

Main encrypted data on Google Drive, fragments and keys on OneDrive. An attacker needs access to both providers to even attempt decryption.

Zero-Knowledge Architecture

We never see your passwords or unencrypted data. You authenticate directly with Google and Microsoft using secure OAuth 2.0.

How Our Security Works (FISSM)

Understanding the revolutionary approach that makes your files virtually uncrackable

File Encryption in Your Browser

Each file gets its own unique, randomly generated password. Your file is encrypted with AES-GCM-256 before any data leaves your device.

Intelligent Data Distribution (FISSM)

The main encrypted chunk goes to Google Drive, while a critical fragment and the decryption key go to OneDrive. Neither provider has the complete picture.

Multi-Factor Authentication Protection

Your existing 2FA/MFA on Google and Microsoft accounts automatically protects your encrypted files. We leverage the security you already have.

Coming Soon

Session Master Password

An upcoming enhancement will add another layer of security with a session master password that encrypts the file-specific passwords, making your data even more secure.

Vaulted Password

For enterprises there will be a file password vault on a secure server and appropriate payment plan.
