Sepio: See What You've Been Missing

Sepio helps public sector organizations see and control the one layer most security stacks still overlook: the physical hardware that actually runs government services, critical infrastructure, and citizen-facing systems.

From federal agencies and defense environments to municipalities, utilities, transit, and education, public organizations are under pressure to modernize, comply with evolving regulations, and defend against increasingly sophisticated attackers—often while operating with legacy systems and constrained budgets. Traditional tools focus on software, identities, and network traffic. Sepio adds the missing hardware dimension.

Using our patented AssetDNA technology, Sepio uniquely fingerprints every device by its electrical and signaling characteristics at the physical layer. That means public sector teams can identify, classify, and continuously validate any device connected to their IT, OT, IoT, and IIoT environments—even if MAC addresses, IP details, or firmware have been spoofed or altered. This physical-layer truth helps agencies detect rogue, shadow, or tampered devices that would otherwise remain invisible.

Sepio’s trafficless, software-only architecture is designed for sensitive and regulated environments. It deploys quickly, without probes, taps, or complex switch reconfiguration, making it suitable for air-gapped networks, mission-critical facilities, and bandwidth-constrained sites. Security and operations teams gain a consolidated, accurate inventory of all hardware assets, enriched with risk context, business criticality, and precise physical location down to the switch port, USB port, or PCI slot.

For the public sector, this translates directly into better cyber resilience and governance. Agencies can:

• Enforce Zero Trust at the hardware level by validating device integrity before access is granted.
• Strengthen compliance with frameworks such as NIST and other government cyber policies by proving device-level visibility and control.
• Reduce incident response times with clear, actionable data on what device is at risk, where it is, and how it is connected.
• By integrating with existing security ecosystems—CMDB, SIEM, SOAR, NAC, and XDR—Sepio enhances, rather than replaces, current investments. The result is a practical path for public sector organizations to harden their critical services against hardware-borne threats and truly “see what they’ve been missing.
