Your Documents Are Safe With Us
Sayina is built with security at its core — from encrypted storage and transmission to tamper-evident audit trails and OTP-verified identities.
Encrypted Storage
All documents are encrypted at rest using AES-256. Only authorised parties can access signed documents.
TLS in Transit
All data in transit is protected by TLS 1.3. Your documents never travel across the internet unencrypted.
OTP Identity Verification
Every signer is verified with a one-time password via email or SMS before their signature is accepted.
Document Hashing
Every document is hashed before and after signing. Any tampering is immediately detectable and invalidates the signature.
South African Hosting
All data is hosted within South Africa or POPIA-approved jurisdictions. Your data never leaves without your consent.
Tamper-Evident Audit Trail
Every action — viewed, signed, declined — is timestamped and cryptographically secured for legal admissibility.
Responsible Disclosure
If you discover a security vulnerability in Sayina, please report it to us responsibly. We take all security reports seriously and aim to respond within 24 hours.
