Security incident on record — Storm-0558 July 2023 — stolen MSA key forged tokens for Exchange Online; CSRB called breach preventable
▪ Editorial verdict
Microsoft Entra Private Access is the most seamless ZTNA for Microsoft-first organisations. The native Conditional Access integration, transparent Microsoft Authenticator experience, and Intune device compliance enforcement create a zero trust access architecture that requires no additional identity infrastructure for M365 customers.
As a GA product since mid-2024, it is newer than Zscaler or Cloudflare and complex legacy application scenarios are less battle-tested. The value is almost entirely within the Microsoft ecosystem. Non-Microsoft OS experience is less polished and non-Microsoft workload integration requires more configuration.
The verdict: Microsoft Entra Private Access is right for Microsoft-first organisations that want ZTNA integrated into their existing Entra identity infrastructure at no additional vendor relationship. Organisations with diverse infrastructure should evaluate Zscaler ZPA or Cloudflare Zero Trust.
