Device Trust Management

We build a complete inventory of devices that access your infrastructure: laptops, phones, CI/CD runners, build servers, and IoT devices. Each device is cataloged with hardware identifiers, assigned owner, enrolled date, last compliance check, and current posture status. The inventory is the single source of truth for device trust decisions. Unknown devices are blocked by default — there is no network path for unenrolled hardware.

Each enrolled device receives a unique X.509 certificate stored in the hardware TPM or secure enclave. The certificate serves as the device's cryptographic identity in zero trust access decisions. Device certificates are issued by your internal CA with short lifetimes (90 days) and automatic renewal. Certificate binding to hardware makes cloning or exfiltrating device identity practically impossible.

Device health is verified through attestation: secure boot verification confirms the OS has not been tampered with, TPM attestation verifies the boot chain integrity, and software inventory checks confirm required security agents are running. Attestation results feed into access decisions. A device that fails attestation is quarantined — it can reach only the remediation portal until it passes health checks again.

Device trust requires lifecycle management: enrollment provisions certificates and installs agents, compliance monitoring runs continuously, ownership transfers update access policies, and decommission revokes certificates and wipes corporate data. When an employee leaves, their device certificates are revoked within the offboarding workflow — not days later when IT remembers. Lifecycle events are logged for audit compliance.
