1Password Passkeys vs Zscaler Secure Private Access with ZTNA: Side-by-Side Comparison (2026)

Short answer

Security teams at startups and SMBs ready to ditch passwords will find 1Password Passkeys the fastest path to phishing-resistant authentication without rebuilding identity infrastructure. Passkey synchronization across Mac, iOS, Windows, and Android means users stay productive while biometric unlock eliminates the friction that kills adoption. Skip this if your organization needs deep integration with existing directory services or passwordless MFA for legacy apps; 1Password Passkeys works best for greenfield deployments and teams comfortable standardizing on new authentication workflows. 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.
