Zero Trust Network Access Platform Comparison — October 22, 2024

Zero trust is not a product, but if you are evaluating platforms that enable zero trust architecture, here's what to look for: continuous verification, least-privilege access, micro-segmentation, and strong identity integration. The major players—Zscaler, Palo Alto, Microsoft, Cloudflare—each have different strengths depending on your environment.

Zero Trust Network Access (ZTNA) programs in 2025 focus on consolidated policy engines, identity-native access controls, and verifiable telemetry for audit teams. Zscaler Private Access, Cloudflare Zero Trust, Palo Alto Networks Prisma Access, Cisco Secure Access, and Okta Identity Governance offer mature combinations of private application access, inline inspection, and compliance reporting.

Buying criteria

  • Unified policy orchestration: Vendors that centralize device posture, identity, and network rules reduce drift across hybrid environments.
  • Edge coverage: Cloud-delivered PoPs with carrier-grade SLAs keep latency within the sub-50 ms thresholds remote users expect.
  • Compliance evidence: FedRAMP, ISO/IEC 27001, SOC 2 Type II, and regional data residency attestations remain procurement prerequisites for critical infrastructure and SaaS buyers.

Zscaler Private Access

  • Delivers inside-out connectivity with software connectors, eliminating inbound VPN tunnels and segmenting application access down to the user and process.
  • FedRAMP High authorization covers U.S. federal workloads; ZPA integrates with Zscaler Digital Experience for end-to-end performance tracing.
  • Policy engine supports conditional access based on device posture, identity attributes from Okta or Microsoft Entra, and user risk scores from third-party feeds.

Cloudflare Zero Trust

  • Runs on Cloudflare’s global network with more than 310 cities, combining Access, Gateway, and Browser Isolation into a single dashboard.
  • Turnkey integrations with identity providers (Okta, Azure AD, Ping Identity) and endpoint security vendors feed posture checks into access policies.
  • Logs stream into Cloudflare’s SIEM integrations or customer-owned storage via R2, helping teams satisfy GDPR and PCI DSS retention mandates.

Palo Alto Networks Prisma Access

  • Extends the Prisma SASE fabric with ZTNA 2.0 controls, inline inspection powered by the CloudBlades partner ecosystem, and advanced DNS security.
  • Prisma Access supports FIPS 140-2 validated cryptography and regional gateways across Americas, EMEA, and APAC to address data residency requirements.
  • Managed Threat Prevention feed and Autonomous Digital Experience Management (ADEM) accelerate response workflows with consolidated alerting.

Cisco Secure Access

  • Formerly Cisco+ Secure Connect, the platform unifies ZTNA, secure web gateway, and cloud firewall policies managed through the Cisco Security Cloud interface.
  • Talos threat intelligence and Duo device trust feed risk scoring decisions into policy enforcement for private and SaaS applications.
  • Integrates with ThousandEyes for experience monitoring and supports DNS-layer filtering via Umbrella for layered protection.

Okta Identity Governance + Okta FastPass

  • Combines Okta’s phishing-resistant FastPass authentication with fine-grained entitlement reviews and access certification workflows.
  • Lifecycle automation enforces just-in-time access for contractors and service accounts, reducing standing privilege across hybrid infrastructure.
  • Okta maintains FedRAMP Moderate and ISO/IEC 27001 certifications, and its System Log exports feed SIEMs for compliance validation.

Control mapping

  • ISO/IEC 27001 Annex A.8: Use entitlement reviews and adaptive authentication to enforce least privilege for remote and third-party users.
  • NIST 800-207: Document policy decision points, policy enforcement points, and continuous diagnostics instrumentation in architectural diagrams.
  • SOC 2 CC6.6: Capture change management approvals when modifying access policies; log exports must include actor, scope, and business justification.

Implementation milestones

  • Run parallel pilots by segmenting a low-risk application group and validating experience for remote, BYOD, and contractor personas.
  • Integrate device compliance signals from endpoint detection and response (CrowdStrike, Microsoft Defender for Endpoint, SentinelOne) to prevent unmanaged hosts from authenticating.
  • Publish executive dashboards that correlate access policy decisions with incident response metrics and audit findings to show Zero Trust program maturity.

Providing vendor-neutral Zero Trust blueprints, including RACI charts, policy templates, and readiness questionnaires for regulated industries.
