Enterprise security has focused almost exclusively on human identities. We implemented multi-factor authentication (MFA) and single sign-on (SSO) to help ensure that "John Doe" was, in fact, John Doe. However, in a world where employees, contractors, and partners access resources from a mix of managed corporate laptops and unmanaged personal devices, the device itself has become a non-human identity that requires access management.
For many organizations, there’s a device identity security gap: verifying users rigorously while treating devices as trusted-by-default terminals. This omission stems from common misconceptions:
- The "managed" fallacy: Assuming that a device is inherently secure from the moment of login because it’s enrolled in mobile device management (MDM)
- The "silo" problem: Treating device access and device posture management as separate from identity security
Gartner identifies identity-first security as a top cybersecurity trend, noting that adopting identity fabric principles can prevent 85% of new attacks. This strategy specifically includes bringing devices into the core identity trust model. Without treating device identities as first-class identities, your Zero Trust architecture is effectively a high-tech lock on a screen door.
Defining device identity beyond the serial number
In a Zero Trust environment, device identities are not static attributes; they are non-human identities that must be verified and serve as vital context for access decisions. The device through which a user accesses corporate resources is a critical point for security enforcement. Every request to access sensitive data must be explicitly verified based on the user's identity, the device’s identity, the device's posture, and the resource's criticality.
To build a resilient security posture, we must treat device identity as a foundational security control that operates on two levels:
- As a gatekeeper: To secure access to the device itself through identity verification and device attestation before a user can unlock or log in to their computer
- As a source of security posture signals: To inform real-time access decisions based on continuous feedback on device posture and compliance
A device's identity encompasses not only its unique hardware fingerprint and credentials, but also its current security state—patch levels, encryption status, endpoint protection status, and compliance posture. By integrating device identity into contextual access control policies, organizations can make granular, risk-based decisions that adapt to the device's real-time condition, across all login touchpoints.

The device foundation of a unified identity security fabric
To secure a diverse array of corporate-owned, managed, and unmanaged (BYOD) devices commonly found in the modern enterprise, organizations require an identity security fabric—an integrated approach to managing and monitoring all identities, human and non-human. It does not necessarily replace existing tools; instead, it weaves them together into a coherent structure that provides a unified layer of visibility and governance, enabling everything from faster threat detection to greater compliance with security mandates.
Device identity cannot exist in a vacuum; it must be a foundational pillar of a unified identity security fabric, with the identity provider acting as the central nervous system, weaving together user context, device signals, and resource sensitivity into every single access decision. When you integrate device identity into the broader fabric, the nature of security shifts from reactive to proactive, with several key outcomes:
Context-driven access decisions
Instead of a binary "allow/deny" based on a password, the system makes nuanced decisions. For example: "Allow John Doe access to the Finance App, but only because he is on a known, managed device with active disk encryption and a low risk score."
Highly secure "day 1" device setup
Traditionally, onboarding a new hire is a manual, high-friction process that creates security gaps. A unified identity security fabric enables zero-touch deployment, allowing organizations to ship a device directly to a user. After multiple layers of identity verification, the process automatically creates and links the user's device account to the corporate user identity, integrating security even before the user opens their first app.
Continuous evaluation rather than static checks
With a unified identity security fabric, the system continuously assesses posture and risk. If a device's risk level changes mid-session, the identity security fabric can automatically terminate the session across all applications and log the user out of their device.
When the device identity is integrated, known, and trusted, organizations can reduce login friction, allowing users to stay productive with fewer MFA prompts while maintaining a more robust defensive posture should conditions change.
What’s next: The journey to device trust
Securing device identities is not an overnight task, but it is a business imperative and an emerging regulatory requirement. As the traditional network perimeter continues to dissolve, the device becomes a critical point of identity threat detection and response. By treating devices as first-class identities within a unified identity security fabric, you don't just close a gap, but build a foundation for a resilient, agile enterprise.
