Zero-Persistence Security Model
The Risk of Resident Data
Most SaaS platforms store sensitive document buffers on local disks during processing. If a server is breached, this data can be exfiltrated. IUSign eliminates this risk through 'Zero-Persistence' architecture.
In-Memory Stream Processing
Sensitive document content exists only in temporary RAM buffers. These buffers are cryptographically wiped (overwritten with zeroes) immediately after the document is encrypted and saved to its final secure destination.
Absolute Sovereignty
By ensuring no unencrypted trace of your document ever touches a physical disk, we provide absolute sovereignty over your most sensitive business data.
Take the next step towards document sovereignty.
