of Zero-Knowledge Cloud Encryption
Real-World Threats
Security threats cloud storage providers face every day
Server Breach
Hackers compromise cloud provider servers
Traditional Impact:
All user data exposed
Nygma Protection:
Encrypted data is useless without your keys
Rogue Employee
Malicious or careless insider with access
Traditional Impact:
Employee can access any file
Nygma Protection:
Employees cannot decrypt user data
Government Surveillance
Court order demands user data
Traditional Impact:
Provider must comply, data exposed
Nygma Protection:
We have nothing to hand over
Database Leak
Backup tapes stolen, database dumped
Traditional Impact:
Plaintext data in backups exposed
Nygma Protection:
All backups are encrypted blobs
Software Vulnerability
Security bug in provider software
Traditional Impact:
Vulnerability may expose plaintext data
Nygma Protection:
Client-side encryption limits exposure
Network Interception
Man-in-the-middle attack on connection
Traditional Impact:
Single TLS layer (if compromised, data exposed)
Nygma Protection:
Double encryption (TLS + client-side)
Defense in Depth
Multiple overlapping security layers protect your data
Client-Side Encryption
Files encrypted before leaving your device
Protects Against:
Server breaches
Rogue employees
Government requests
Zero-Knowledge Architecture
Server never sees decryption keys
Protects Against:
Database leaks
Backup compromises
Subpoenas
Per-Device Keys
Each device has independent encryption keys
Protects Against:
Device theft
Lost phones
Compromised computers
Transport Layer Security
TLS 1.3 for all connections
Protects Against:
Network sniffing
Man-in-the-middle
ISP surveillance
Nygma vs Traditional Cloud
How we respond to real security incidents
Hackers breach provider servers
Traditional Cloud
All files exposed
Provider holds decryption keys, attackers get plaintext data
Nygma
Only encrypted blobs exposed
Attackers get gibberish they cannot decrypt
Government issues court order
Traditional Cloud
Provider must hand over data
Provider can decrypt and comply with order
Nygma
Nothing to hand over
We only have encrypted blobs with no keys
Employee goes rogue
Traditional Cloud
Employee can access files
Insiders have technical ability to view data
Nygma
Employee sees only encrypted data
No employee has decryption keys
Database backup stolen
Traditional Cloud
Plaintext data in backups
Backups often contain unencrypted or weakly encrypted data
Nygma
Encrypted blobs in backups
Backups are just encrypted copies
Our Security Practices
Beyond encryption - how we maintain security
Regular Security Audits
Third-party penetration testing and code audits
Bug Bounty Program
Rewards for responsible disclosure of vulnerabilities
Open Source Clients
Encryption code is open for community review
Transparency Reports
Public reporting of any security incidents
What If Scenarios
What if Nygma gets hacked?
Hackers would get encrypted blobs with no decryption keys. Your data remains safe. We would notify users and conduct full security audit, but your files would not be compromised.
What if government forces us to add a backdoor?
We cannot add a backdoor without changing the open-source client code, which would be immediately noticed by the security community. We would shut down before compromising user security.
What if there is a bug in the encryption?
We use battle-tested encryption libraries (OpenSSL, libsodium) that have been audited by thousands of security experts. Our code is open source for community review. Bug bounty program rewards responsible disclosure.
What if quantum computers break encryption?
We monitor post-quantum cryptography research. When quantum-resistant algorithms are standardized, we will add support while maintaining backward compatibility. Your existing data can be re-encrypted with quantum-safe algorithms.
