SEPIO is a Zero Trust Hardware Access platform that helps organizations discover, verify, and control the true identity of every connected hardware asset across IT, OT, IoT, and CPS environments. Traditional security tools rely heavily on what devices report about themselves, such as MAC addresses, IP addresses, hostnames, agents, certificates, firmware data, or network behavior. These signals can be incomplete, missing, manipulated, or unavailable. SEPIO takes a different approach by using patented AssetDNA technology to validate device identity based on physical-layer characteristics, helping security teams understand what a device truly is — not just what it claims to be. SEPIO helps CISOs, security operations teams, infrastructure teams, and critical infrastructure operators eliminate hardware blind spots created by rogue devices, spoofed devices, unmanaged assets, shadow IT, unauthorized peripherals, supply-chain-compromised hardware, and devices that cannot support traditional security agents. The platform provides continuous asset visibility, hardware risk detection, policy-based control, and actionable mitigation guidance across complex and distributed environments. Unlike traffic-based monitoring tools, SEPIO is trafficless, protocol-agnostic, and encryption-independent. It does not require network taps, passive probes, traffic inspection, or endpoint agents for network asset discovery. This allows organizations to deploy quickly, reduce operational complexity, and gain visibility into connected assets without disrupting sensitive environments. SEPIO complements existing security investments, including NAC, EDR, XDR, CMDB, SIEM, SOAR, and vulnerability management platforms, by adding a hardware-level source of truth. By verifying device identity before trust is granted, SEPIO extends Zero Trust principles down to the hardware layer and helps organizations improve cyber resilience, asset governance, compliance readiness, and protection against hardware-based cyber risk. SEPIO is used by enterprises, financial institutions, healthcare organizations, government agencies, manufacturers, telecom providers, and critical infrastructure operators that need trusted visibility and control over the hardware assets connected to their environments.
