Microsoft's hard-match protections in Entra ID took effect in mid 2026. A hard match onto a cloud account that holds or is eligible for an Entra role is now blocked in the service, whichever version of Connect Sync or Cloud Sync you run. Tenants that hit this during a migration usually resolve it by turning on the temporary bypass flag, and then leave it on, which is the state we are most often called in to find and unwind.
A second, harder deadline is still ahead. Microsoft states that all synchronization services in Entra Connect Sync stop working on 30 September 2026 for tenants below version 2.5.79.0.
We help organizations migrate from legacy Active Directory to Entra ID with Zero Trust Conditional Access policies, without breaking workflows or creating governance gaps. Our engagement covers three critical areas: Hybrid Identity Gaps (Hybrid Join devices that were never migrated to Entra ID Join, creating shadow access paths outside your Conditional Access policies), Conditional Access Gaps (policies that block legitimate workflows or leave gaps that attackers exploit, we audit, remediate, and test every policy), and Hard-Match Exposure (a bypass flag left enabled after a migration, or a Connect Sync version that will stop synchronizing on 30 September 2026).
We connect to your tenant (read-only), audit your Entra ID, Conditional Access, and device posture configuration, and deliver a prioritized remediation report on a timeline we agree with you before we start. No commitment. No pitch.
The Challenges You Face
Passkey & Conditional Access Conflicts
Microsoft's March 2026 passkey rollout is silently breaking Conditional Access policies across enterprise tenants.
M&A Identity Fragmentation
B2B guest access can provide immediate Day 1 continuity. When temporary access becomes the permanent operating model, organizations can accumulate duplicate identities, inconsistent lifecycle controls, and fragmented security visibility.
Hybrid Join Device Trap
Devices still tied to legacy AD cause policy mismatches and shadow access paths outside your Conditional Access policies.
Standing Hard-Match Bypass
The tenant flag that unblocks a stalled migration is meant to be temporary, and is usually still enabled months later.
