  • Provide subject-matter expertise with Active Directory identity protection best-practices, synchronization, and hybrid infrastructures.   
  • Help clients review and assess Active Directory integration and hardening with virtualization infrastructure and platforms. 
  • Create and document detailed guides and tracking documents - for clients to leverage as part of Active Directory hardening and overall infrastructure enhancements. 
  • Recommend and document specific countermeasures and mitigating controls based upon identified gaps and weaknesses. 
  • Develop comprehensive and accurate reports and presentations for both technical and executive audiences.
