Device Trust
Device trust: is the endpoint a known, honest device?
Device trust is confidence that the hardware and software environment presenting an identity is the expected device, in an expected state.

Problem
User authentication is often accepted from any browser or app instance that holds a token.

Definition
Device identity names a specific device. Device attestation is evidence about its integrity or properties, often using a hardware root of trust such as a secure element, TPM, or TEE.
Device Trust
Why it matters
Account takeover frequently uses a new device. Malware on a known device can still replay sessions. Device trust addresses a different question from human identity: what is presenting the credentials?
Device Trust
How it works
Devices may hold unique keys, join a fleet via enrollment, and produce attestations that an app or OS state matches policy. Mobile platforms expose attestation APIs with vendor-specific trust models.
SIM and eSIM identities are a telecom-rooted form of device/subscriber binding. They are powerful possession factors, not a complete malware defense.
Device Trust
Limitations
Attestation can be bypassed or incomplete. Hardware roots reduce risk; they do not make a device unhackable.

Where this meets Keyra
Keyra operates device-verification and mobile-app surfaces (including verify-device flows). Those are application features, not public proof that every Keyra authentication is hardware-attested.
Questions
What people ask first.
Plain answers. No product claims that have not been published elsewhere on Keyra.ie.
Is a device fingerprint device identity?
Fingerprints are probabilistic signals. Cryptographic device keys and hardware attestation are stronger identity mechanisms.
Does MDM equal device trust?
MDM can enforce policy. Trust still depends on enrollment integrity and the quality of compliance signals.
