Case Study: Leading Financial Institution achieves Zero Trust hardware visibility and rogue device mitigation with Sepio

Leading Financial Institution Company - Customer Case Study

Leading Financial Institution needed better visibility and control over hardware assets in a complex IT/OT/IoT environment, with a particular zero trust challenge around devices manipulated at the physical layer. The organization was exposed to a man-in-the-middle network attack using a rogue Raspberry Pi configured to impersonate a legitimate printer, allowing traffic interception and exfiltration without being detected by existing NAC, IDS, or other security tools. Sepio’s HAC-1 hardware access control platform was used to address the issue.

Sepio implemented a zero trust hardware access policy using physical-layer fingerprinting to verify the printer’s true identity, detect hidden or rogue devices, and assess device risk with built-in threat intelligence. The solution provided complete visibility and mitigation for hardware assets that were previously invisible to other tools, helping the customer enforce zero trust controls for IoT devices and prevent the rogue printer from bypassing micro-segmentation policies. The case study does not provide a numeric impact, but it reports that Sepio enabled full detection and control over the attack scenario.
