Product Comparison
IUSign vs Permanent Storage
for Zero-Persistence Security
Traditional e-signatures store your private documents on their servers forever. iusign shreds the data the moment the transaction is complete.
Permanent Storage Typical Flow
Permanent vendor storage; risk of database leaks; third-party trust required.
- Contract sits on vendor server for 5+ years
- Vendor has access to metadata
- Storage breach = exposure
IUSign Workflow
Ephemeral merge flow; AES-256 GCM envelope encryption; GCP KMS key wrapping.
- Document exists only in memory during signing
- Crypto-shredding on completion
- You own the audit hash chain
Impact
Your documents cannot be leaked because they aren't there.
