Device Identity Platform™ overview

The other half of Zero Trust

Most organizations start their Zero Trust journey with Single Sign-On (SSO), Multi-Factor Authentication (MFA), and user access policies. Yet every endpoint—laptops, servers, containers, and IoT devices—represents another identity that can be compromised. True Zero Trust requires securing both user and device identities.

High assurance device identity for Enterprise IT

Device identity ensures only trusted, company-owned devices can access your most sensitive resources, including Wi-Fi networks, VPNs, financial dashboards, intellectual property, and GDPR-sensitive databases. Smallstep delivers hardware-backed device identity, providing the strongest protection against credential theft, phishing, and impersonation attacks.

ACME Device Attestation is here to replace SCEP

Smallstep worked with Google at the IETF to develop the new standard for high-assurance device identity, ACME Device Attestation (ACME DA). ACME DA provides the strongest possible guarantee of authentic device identity, preventing credential exfiltration, phishing, and impersonation attacks.

Built on trusted open source foundations

Smallstep’s platform is built upon proven, open-source software trusted by 78 of the Fortune 100 companies to secure critical DevOps workloads. Our cryptographic code benefits from transparency and rigorous community scrutiny—delivering security you can rely on.

Critical components of device identity

By bridging the gap between security standards and operational reality, Smallstep simplifies the implementation of high assurance device access, providing businesses with a modern and secure ecosystem. To achieve high assurance device identity you’ll need four foundational components in place.

Integrates with your existing security stack

The Device Identity Platform™ extends your existing enterprise ecosystem. We integrate with all major mobile device management (MDM), identity provider (IdP), and device posture platforms to provide a seamless and secure user experience. These integrations augment and harden user identity and extend the reach of device posture systems by automatically revoking device credentials when a device is removed from inventory or if posture checks fail.

Leading the industry in Zero Trust for devices

Empower your teams to work at the pace and scale of modern engineering.
