Introducing the world’s first Device Identity Platform™
Ensure only company-owned devices can access sensitive resources.
Smallstep solves the other half of Zero Trust by securing Wi‑Fi, VPNs, ZTNA, SaaS apps, cloud APIs, and more with hardware-bound credentials backed by ACME Device Attestation.
Trusted by 78 of the Fortune 100
Introducing ACME Device Attestation
Smallstep co-developed a real standard for high-assurance device identity with Google at the IETF. It's called ACME Device Attestation, ACME DA for short, and is a major upgrade to existing solutions like SCEP. ACME DA leverages hardware co-processors for attestation and keybinding⎯like a fingerprint for your device⎯ preventing credential exfiltration, phishing, and impersonation attacks.
Hardware-bound credentials for all the things ✨
Device identity ensures that only company-owned devices can access your enterprise's most sensitive resources. This includes Wi-Fi networks, VPNs, financial dashboards, intellectual property, databases with GDPR-scoped PII, and Git repos. The Device Identity Platform™ provides the strongest possible guarantee of authentic device identity by binding access to the device's silicon.
Go beyond user credentials
Zero Trust is more than user authentication. It’s about verifying everything: people, and devices, even the applications or services they run. A robust Device Identity strategy will keep your enterprise ahead of breaches, especially with remote work and cloud adoption on the rise.
Multi-OS support is already here
Smallstep supports ACME DA natively on all operating systems. This enables consistent and secure cross-platform access no matter which OS your team prefers. MacOS, Windows, and notably Linux, protect them all (and your enterprise) with cross-platform device identity.

Senior Security Engineer • Visual Media Platform
"We started trying to build this ourselves, and it was a total tire fire. Far more expensive than we first estimated."
Security Architect • Social Technology Company
"We weren’t interested in device identity as a hobby. We needed a single solution with an architecture that solves for all our use cases."
