● THREAT: HARDWARE-LAYER BLIND SPOTS

Zero Trust Starts
at the Hardware
Layer.

Sepio delivers the missing foundation of Zero Trust — validating devices based on what they physically are, not what they claim to be. Using physical-layer metadata and Hardware AssetDNA™, Sepio reveals impersonation, spoofing, and hidden risks that every other security tool misses.

● THE HARDWARE BLIND SPOT

Your Zero Trust Programme
Has a Hardware Gap.

Most Zero Trust programmes operate under a flawed assumption — that device identity can be trusted based on self-reporting or inventory systems. Attackers exploit this gap by impersonating trusted hardware at the physical layer, bypassing NAC, EDR, and every software-centric control.

Threat: Hardware-based HID and BadUSB attacks

USB & Peripheral Attacks

Malicious USB devices, HID spoofing attacks, and rogue peripherals that bypass endpoint security by impersonating trusted hardware.

Threat: Rogue devices creating hidden network access

Rogue Network Devices

Unauthorised switches, access points, and network taps that create invisible lateral movement paths invisible to NAC and EDR tools.

Threat: MAC spoofing and device identity fraud

Hardware Impersonation

Devices that spoof MAC addresses and device identities to bypass network access controls and appear as trusted assets in your inventory.

Threat: Unmanaged IoT and OT devices on the network

IoT & OT Blind Spots

Industrial controllers, smart building systems, and IoT devices that are invisible to software-centric security tools but fully accessible to attackers.

ZERO TRUST HARDWARE ACCESS FRAMEWORK

Five Steps to
Hardware Zero Trust.

Sepio's structured framework takes organisations from hardware blind spots to complete physical-layer Zero Trust — covering every device from workstations to IoT sensors to USB peripherals.

01

Visibility

The most comprehensive device discovery available — maps all connected devices including those invisible to network-centric tools. IT, IoT, Shadow IT, USB, and OT devices all surfaced.

Complete hardware asset inventory in hours
02

Identification

Generates a unique Hardware AssetDNA™ for every device using physical-layer metadata. Establishes accurate asset identity based on physical characteristics, not self-reported claims.

Hardware AssetDNA™ — unforgeable device identity
03

Risk

Continuous validation of device behaviour, configuration, and compliance against security policies. Easy-to-understand individual risk indicators and aggregate risk scores per device.

Per-device risk score with continuous monitoring
04

Policy

Flexible, native policy engine with rules based on device type, behaviour, and location. Define exactly which hardware is permitted on which network segment.

Granular hardware access policies per segment
05

Control & Enforcement

Integrates with NAC, SIEM, and SOAR for real-time notification, alerting, and active denial of unauthorised or non-compliant devices. Automated response in milliseconds.

Active denial of rogue hardware in real time
