System integrations

How your systems connect — and what guards the wire

Every number on your dashboard arrives over one of these bridges. Each one is encrypted, monitored, screened by Fraud Shield, and logged to a tamper-evident audit chain.

State of the art

The cybersecurity layer

Encryption everywhere

AES-256 at rest, TLS 1.3 in transit — every balance, every file, every credential. Keys rotate automatically on a 90-day cycle in a hardware security module.

Zero-trust access

Every session is fingerprinted and re-verified per request. Sensitive actions — payments, exception decisions, entitlement changes — require step-up MFA.

Credentials never stored

Portal links use OAuth or bank-issued tokens. LEDGERLINK holds no passwords to lose — revoke any connection with one click.

Hash-chained audit trail

Every action — every login, every decision, every file — is written to a tamper-evident, hash-chained audit log. Nothing edits history.

Hardened infrastructure

SOC 2 Type II data centers, isolated per-tenant encryption contexts, continuous vulnerability scanning, and third-party penetration tests twice a year.

24/7 monitored

The FNB fraud desk and an around-the-clock security operations center watch every bridge. Anomalies page a human in minutes, not mornings.
