Enterprise Security & Trust

Security Designed for Confidential Client Data

Professional service firms handle highly sensitive financial, tax, and legal records. OnboardFlow is architected from the ground up with enterprise-grade isolation and encryption.

Encryption in Transit & At Rest

All client file uploads and database records are safeguarded with TLS 1.3 in transit and AES-256 at rest.

Per-Tenant Data Isolation

Multi-tenant architecture enforces strict logical boundaries. Data from one firm is completely partitioned from all others.

Role-Enforced Access Control

Granular permissions separate Admins, Case Managers, Review Staff, and external Client Participants.

Immutable Action Logging

Every document submission, review action, rejection reason, and status modification is permanently audit-logged.

Isolated File Storage

Client documents are stored in cryptographically sealed object containers with zero public bucket exposure.

Secure Verification Tokens

Time-limited, cryptographically signed portal access tokens ensure only verified clients can access their checklist.

“Before OnboardFlow, our tax season kick-off was a nightmare of lost email attachments and incomplete questionnaires. Now, every client gets a clean, branded portal with a clear checklist. Our document collection cycle dropped from three weeks to under 48 hours.”
