Sepio
Sepio provides Zero Trust Hardware Access (ZTHA) by validating devices based on their physical-layer metadata rather than software-reported identities. The platform generates a unique Hardware AssetDNA™ for each connected device, exposing spoofing, impersonation, and hidden rogue hardware that traditional NAC/EDR tools miss. It continuously discovers authorized, unmanaged, and dormant assets across IT, OT, and IoT environments, then automates policy-driven mitigation through integrations with existing security stacks.

Problem
Most Zero Trust programs still trust device identity based on what a device reports or what an inventory system says, creating dangerous blind spots for unmanaged, dormant, or spoofed hardware. Attackers can impersonate trusted assets and bypass traditional security controls because nothing validates a device's real physical identity at Layer 1, leaving organizations exposed to shadow IT, rogue devices, and internal attacks.
Solution
Sepio delivers the missing foundation of Zero Trust by validating devices based on what they physically are, not what they claim to be. Using physical-layer metadata, Sepio generates a unique Hardware AssetDNA™ for every connected device, revealing impersonation, spoofing, and hidden risks that traditional cybersecurity tools cannot detect. The platform continuously discovers authorized, unmanaged, and hidden assets across IT, OT, and IoT environments, then converts risk into action with policy-driven controls to contain, block, isolate, or escalate using verified identity and context. Sepio integrates with existing security and IT asset management stacks, providing trusted data to streamline response and remediation while ensuring governance and compliance are based on reality rather than assumptions.
Target Audience
Primary customers are enterprise security teams, including CISOs, network security architects, and IT operations leaders, who need to close hardware-level blind spots in Zero Trust architectures across IT, OT, and IoT environments.
Features
- Hardware AssetDNA™ generation using physical-layer metadata to validate true device identity and expose spoofing or impersonation
- Continuous discovery of authorized, unmanaged, dormant, and hidden assets across IT, OT, IoT, and peripheral environments
- Automated risk mitigation with policy-driven controls to contain, block, isolate, or escalate based on verified identity and context
- Integrations with NAC, EDR, SIEM, and ITAM stacks to scale Zero Trust and streamline response workflows
- Detection of shadow IT, dormant implants, dual-use devices, and non-obvious rogue hardware that evade network-centric tools
