Zero Trust
A security model that requires continuous verification of every user, device, and network flow before granting access—eliminating implicit trust based on network location. The foundation of modern IoT/OT security architecture.
What is Zero Trust?
A security model that requires continuous verification of every user, device, and network flow before granting access—eliminating implicit trust based on network location. The foundation of modern IoT/OT security architecture.
Zero Trust is a security philosophy built on the principle of "never trust, always verify." In a traditional perimeter-based model, devices and users inside the corporate network are implicitly trusted. Zero Trust eliminates that implicit trust: every access request must be authenticated, authorized, and continuously validated — regardless of where it originates.
The shift to Zero Trust has been driven by the collapse of the network perimeter. Cloud workloads, remote users, and mobile devices mean that the concept of "inside the network" no longer reliably corresponds to "trusted." Meanwhile, attackers who achieve initial access routinely exploit implicit trust to move laterally and escalate privileges.
Zero Trust for IoT and OT environments presents unique challenges. Traditional Zero Trust implementations assume devices can authenticate with identity credentials, run compliance checks, and participate in policy enforcement. Most IoT, OT, and IoMT devices cannot do any of these things. Extending Zero Trust to unmanaged devices requires a network-centric approach: device identity is established through fingerprinting and behavioral analysis rather than credential-based authentication, and policy enforcement happens at the network layer rather than on the endpoint.
Key Facts
- 72% of CISOs cite extending Zero Trust to IoT as their top implementation challenge
- CISA's Zero Trust Maturity Model explicitly addresses non-traditional devices including IoT and OT
- Federal agencies are mandated by Executive Order 14028 to implement Zero Trust architectures by 2024
- Zero Trust adoption reduces breach cost by an average of $1.5M compared to traditional perimeter models
How ORDR Addresses Zero Trust
ORDR extends Zero Trust principles to connected assets that cannot run traditional security agents. By classifying every device, establishing behavioral baselines, and generating least-privilege network policies, ORDR enables Zero Trust enforcement at the network layer — ensuring that each device can only reach the specific destinations it legitimately needs, with all other access denied by default.
