1Kosmos Identity-Backed Biometrics vs Zscaler Secure Private Access with ZTNA: Side-by-Side Comparison (2026)

Short answer

Organizations replacing passwords with passwordless authentication need Identity-Backed Biometrics if liveness detection and government-ID verification matter more than SSO breadth. FIDO2 certification plus iBeta-certified liveness detection means you're getting cryptographically sound biometrics tied to real identity, not just fingerprint matching, and IAL2 compliance covers federal contractor requirements without retrofit. Skip this if your priority is replacing legacy AD/SAML infrastructure across 50 SaaS apps; 1Kosmos excels at high-assurance onboarding and device unlock, not at being your primary identity provider for everything. Mid-market and enterprise security teams replacing VPN with zero trust will find Zscaler Secure Private Access with ZTNA most valuable for its application segmentation that actually works without network discovery hell; the AI-powered policy automation cuts weeks of manual access mapping. The workload-to-workload segmentation across hybrid and multicloud environments maps directly to NIST PR.AA identity controls, and the inline Layer 7 inspection prevents the access-granted-now-exploited-later scenario that plagues simpler ZTNA deployments. Skip this if you need the strictest on-premises-only architecture or lack the hybrid infrastructure to justify the complexity; pure network microsegmentation tools will do less and cost less.
