About

Trimarc: From Trimarcisia, “feat of three horsemen,” was an ancient Celtic military cavalry tactic where there was always a rider ready to mount the horse of a fallen soldier.

Trimarc Security, LLC (“Trimarc”) is a professional services company based out of Washington, DC that improves the security of Active Directory, Microsoft Exchange, and Vmware virtual infrastructure. We focus on a “reality-based security model” which targets attacker tactics and how to stop them. Our methodology identifies security issues in an organization attackers could exploit to fully compromise the environment and provide custom recommendations to effectively mitigate these issues.

Modern Active Directory environments are typically not aligned to best protect the enterprise from the current threats. The attack vectors that were theoretical years ago are now practical. Additionally, one of the biggest vulnerabilities that most enterprises have is the legacy administration and management of the enterprise. Many organizations are still using group membership in Domain Admins to grant Active Directory administrative rights for admins and service accounts. There are a number of methods used to escalate attacker permissions once they gain a foothold and have malicious code running on one or more computers inside the perimeter. In order to properly protect modern networks a new focus on admin credential protection and management is required.

Our Active Directory security review identifies many potential escalation paths attackers could leverage to go from a normal user to Domain Admin This review includes a full review of admin groups and accounts, Group Policy settings & permissions, Domain & OU permissions, Domain Controller configuration & security, and more. Our review process is continuously refined to provide the best, most comprehensive review of your Active Directory environment available today.

Trimarc works on continuously developing defensive strategies to combat evolving attack techniques. We focus on defensive layers within the enterprise – while any single defense may fail, there are others that compensate for this and provide additional detection and/or mitigation for that area.
