AccessMatrix UAS vs Tesseral: Side-by-Side Comparison (2026)

AccessMatrix UAS

Mid-market and enterprise teams standardizing on vendor-agnostic authentication will find AccessMatrix UAS valuable for avoiding lock-in while supporting biometrics, FIDO2, and hardware security modules in parallel. The platform handles 100 million plus user scale and integrates with token vendors from OneSpan to Thales without custom engineering, which matters when you're already managing heterogeneous hardware across regions. Skip this if your organization needs out-of-the-box connectors to your existing identity provider; AccessMatrix is an authentication server, not a replacement for your IAM platform.

Tesseral

Startups and SMBs building multi-tenant SaaS need Tesseral for passkey-first authentication that actually stops phishing instead of just adding friction. The pre-built login UI cuts implementation time to weeks rather than months, and native SCIM plus custom RBAC mean you're not bolting together five different vendors for user lifecycle management. Skip Tesseral if you need mature SOC 2 Type II audits or deep API gateway features; a three-person team limits the audit footprint and scope relative to what mid-market security teams typically require.
