ABOUT

TrimarcAvatar-black.png

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 was named based on this approach - even if the initial mitigation fails, there are additional defensive layers to back that up.

Trimarc is a professional services company based out of Washington, DC that helps organizations secure their Microsoft platform, both on-premises and in the cloud. Founded by Sean Metcalf, a Microsoft Certified Master in Active Directory, Trimarc's mission is to help organizations better secure their critical IT infrastructure.

We focus on a “reality-based security model” which targets attacker tactics and how to best 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.
 

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.

Our "sales calls" don't include marketing slides or slick sales pitches; we just want to hear about your concerns and challenges. If what we do aligns with what you need, we can talk about scoping and next steps!
