Smallstep Device Identity Platform is a commercial certificate lifecycle management tool by Smallstep. AppViewX AVX ONE SSH is a commercial certificate lifecycle management tool by AppViewX. Compare features, ratings, integrations, and community reviews side by side to find the best certificate lifecycle management fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams enforcing Zero Trust endpoint access will benefit most from Smallstep Device Identity Platform because it replaces fragile SCEP workflows with hardware-backed credentials that survive MDM failures and posture drift. ACME Device Attestation support and automatic revocation on failed compliance checks give you the cryptographic foundation that NIST PR.AA requires without the operational drag of manual certificate management. Skip this if your fleet is primarily browser-based or you're still building out device posture visibility; Smallstep assumes you already have MDM instrumentation and need the next layer of enforcement.
Enterprise and mid-market security teams drowning in unmanaged SSH keys across hybrid clouds should pick AppViewX AVX ONE SSH because it actually finds and inventories what you have before enforcing policy, not the other way around. The platform maps directly to NIST ID.AM and PR.AA, meaning you get asset discovery tied to access controls in one system rather than bolting together separate tools. Skip this if your organization has fewer than 500 users or hasn't experienced a breach or audit failure tied to SSH key sprawl; the operational overhead won't justify the cost at that scale.
