What Zero Trust actually means
Zero Trust isn't a product you buy — it's a security model. The old "castle-and-moat" approach trusted anything inside the network perimeter. Zero Trust assumes breach and verifies every request, regardless of where it originates — inside or outside the network.
The core principle: every access request must be authenticated, authorized, and encrypted before it's granted — and only the minimum access needed is given (least privilege).
Six practical building blocks
| Pillar | How IDENETY implements it |
|---|---|
| Verify identity | MFA everywhere + Entra Conditional Access policies |
| Validate device | Intune compliance policies — non-compliant devices blocked before access |
| Least privilege | Role-based access control (RBAC) + just-in-time (JIT) elevation via PIM |
| Segment the network | VLANs + micro-segmentation to contain lateral movement |
| Inspect & log | SIEM correlation and 24/7 monitoring for anomalous access patterns |
| Encrypt everywhere | TLS in transit, BitLocker/FileVault at rest, encrypted backups |
Where to start
Most organizations get 80% of the Zero Trust value from three moves: enforce MFA for all users, require compliant devices via Conditional Access, and block legacy authentication protocols. These three controls close the most common attack paths with the least disruption.
From there, layer in network segmentation (see our VLAN segmentation guide), vulnerability management (see our vulnerability management guide), and SIEM monitoring — all of which are included in the IDENETY COMPLETE plan.
IDENETY can baseline your environment, identify gaps against the Zero Trust framework, and implement controls in a phased approach that minimizes disruption. Contact our engineers to schedule a Zero Trust assessment.
