Active Directory Health & Architecture
A secure, resilient foundation for everything else.
Assess, redesign, and harden Active Directory — from replication and multi-forest topology to a tiered administration model that contains credential-theft attacks.
The problem
Active Directory is the backbone of enterprise access, yet it is often decades old, under-documented, and over-privileged. Replication issues, sprawling Domain Admin membership, and flat administration models give attackers a direct path to domain dominance. A single compromised workstation should not equal a compromised domain.
What's included
- Comprehensive AD health assessment (replication, DNS, FSMO, DC topology)
- Security posture review against tiered administration best practices
- Multi-domain / multi-forest design or consolidation recommendations
- Privileged group cleanup and least-privilege delegation model
- Tier 0/1/2 administration model with secure admin workstation (PAW) guidance
- Group Policy review and hardening baselines
- Backup, recovery, and AD resilience validation
Typical timeline
Assessment
2–3 weeksCollect data, analyze health, and score security posture.
Design
2 weeksTiered model, topology, and delegation design.
Remediation
4–8 weeksGuided implementation of prioritized fixes.
Frequently asked questions
Tiering separates control of high-value assets (domain controllers — Tier 0) from servers (Tier 1) and workstations (Tier 2), and prevents credentials from one tier being exposed on another. It is the single most effective control against credential-theft lateral movement.
