Case Study: National Bank secures ATM data collection with Owl Cyber Defense data diodes

National Bank secures ATM data flow with Owl Cyber Defense using 1U data diodes

A national bank faced the challenge of securing its central data repository database from external cyber threats while continuing to collect trusted ATM security and transaction data sent via email from disparate field locations. Its existing software firewalls were deemed insufficient. The bank engaged Owl Cyber Defense to implement a solution that would permit only whitelisted emails into the repository while eliminating any possibility of external data access or exfiltration.

Owl Cyber Defense deployed its OPDS-100 data diodes to work in conjunction with the bank's pre-existing firewall. This solution created a hardware-enforced, deterministic one-way data flow, which allowed the trusted inbound ATM data via email while eliminating all outbound connections from the secure repository. The results included a secure network perimeter, the prevention of all data exfiltration, and the maintenance of business continuity for the national bank.
