Zscaler / SSE-led ZTNA
Vendor-reported ZTNA within broader SSE portfolios. Evaluate private app onboarding effort and posture integrations.
- SSE adjacency
- Network change management needed
- Confirm data residency

Best ZTNA solutions
ZTNA should publish private apps to verified users and devices without placing them on a flat network. Shortlist by IdP fit, device posture, and private app discovery effort.
Quick answer
Quick answer
ZTNA should publish private apps to verified users and devices without placing them on a flat network. Shortlist by IdP fit, device posture, and private app discovery effort.
- Treat ZTNA as an application migration program
- Device posture and IdP hygiene come first
- SecurityCheckli.st rating: Not assigned
Shortlist to evaluate
Order reflects common buying patterns, not a scored ranking. Confirm fit in a pilot.
Rank 2
Palo Alto Prisma / peer SASE vendors (ZTNA features)
Treat ZTNA modules as products with their own success metrics, not free extras. See also SASE shortlist.
- Platform alignment benefits
- Complexity risk
- Pilot a critical app first
Rank 3
Cloudflare / modern edge ZTNA offerings
Vendor-reported Zero Trust products emphasize simplified connectors. Validate protocol support for legacy apps.
- Often faster pilots
- Legacy protocol gaps possible
- IdP integration is central
Rank 4
Microsoft Entra Private Access / Global Secure Access path
Evaluate alongside Conditional Access and Intune posture. Confirm workload coverage versus third-party ZTNA maturity for your apps.
- Identity-native fit
- Feature velocity is high; re-verify quarterly
- Good for Microsoft-standardized orgs
Rank 5
VPN hardening (transitional only)
Split-tunnel policy, MFA, and device checks reduce harm but keep network-level trust. Time-box this state.
- Not a destination
- Still useful as bridge
- Track app migration burndown

How to choose in this category
App inventory
You cannot publish what you have not listed.
Device posture
ZTNA without posture often recreates VPN trust on a nicer portal.
IdP alignment
SSO and lifecycle events must be clean first.
Protocol reality
Thick clients and exotic protocols break naive designs.
Contractor paths
Third parties need scoped apps, not whole networks.
Rating
SecurityCheckli.st rating: Not assigned.
Buying guidance
ZTNA success is an application migration program
Zero trust network access projects fail when treated as a weekend VPN swap. They succeed when application owners accept connector changes, DNS patterns, and user communication plans.
Buyer fit diverges: Microsoft-standardized firms should pressure-test Entra private access paths before adding another agent. Multi-cloud and heavy third-party access environments often benefit from dedicated ZTNA/SSE vendors. Always compare against the remote workforce stack guidance.
Limitations
ZTNA does not encrypt SaaS-to-SaaS abuse inside approved apps, nor does it replace email security. It also cannot invent device compliance if MDM enrollment is optional and unenforced.

Frequently asked questions
Do you publish a numeric SecurityCheckli.st rating on this page?
No. SecurityCheckli.st rating: Not assigned until evidence supports a published score. We will not invent a number to fill a table.
Are product capabilities independently verified?
Unless an evidence block marks a finding as confirmed, treat detailed capability claims as vendor-reported and validate them in your own tenancy or pilot.
Is ZTNA the same as SASE?
ZTNA is a private application access pattern. SASE usually bundles ZTNA with SWG, CASB, and related SSE services. See the SASE shortlist.
Can ZTNA replace VPN completely?
Often eventually, rarely on day one. Plan dual-run and exception handling for stubborn apps.
What breaks first in pilots?
Split DNS assumptions, legacy thick clients, and missing device compliance signals.
Where do I capture app lists?
Checklist plus the vendor shortlist worksheet.
