Active Directory
Directories, Modernised.
Security, Strengthened.
Legacy Active Directory environments create security vulnerabilities and operational inefficiencies that constrain business growth whilst increasing cyber risk exposure.
At Cordant, we modernise Active Directory infrastructures through systematic hardening, forest consolidation, and infrastructure upgrades that transform legacy directory services into robust, secure, and operationally efficient identity foundations.
We eliminate technical debt whilst implementing security best practices that align with Microsoft's hardening guidance and Australian cybersecurity frameworks, ensuring your directory services support business objectives whilst maintaining robust security postures.
Our modernisation services span infrastructure hardening with advanced security controls, forest consolidation and migration for simplified management, and comprehensive infrastructure modernisation that enables modern capabilities and operational excellence.
