AD Security Roadmap

January 12, 2026 by
AD Security Roadmap
Resilix, Benjamin Bosch

This is the first overview-post of a new series "AD Security Roadmap". In this first post, we propose a roadmap to gradually improve your Active Directory security posture. Instead of trying to fix everything at once, this approach breaks the work into clear, achievable milestones. Each step reinforcing the next.


Every month, we’ll publish a focused blog post that dives deeper into the corresponding theme. Each article will highlight practical guidance, real-world pitfalls, and actionable takeaways to help organizations turn AD security best practices into concrete improvements.


Taken together, these posts create a structured learning journey, from foundational hygiene and privilege reduction to stronger hardening and long-term resilience across your Active Directory environment.
