Unparalleled Experience
Blackthorne’s team has experience managing risk and leading teams for U.S Department of Defense; Fortune 100 companies such as Microsoft and General Electric; Big 4 consulting firms; and large healthcare, financial services, and emerging technology companies.
Data-Driven Results
Where others look to understand security through conversations and interviews, we find that data and measurement provide real ground truth. Our approach starts with data collection and identifying real gaps and issues instead of relying on existing documentation and word of mouth. We incorporate leading practices to drive optimum results.
Tailored Solutions
Each environment is unique with its own set of challenges. Our approach relies on partnership, creating solutions that are effective and actionable in your environment.
Adversary-Informed Solutions
Our team’s deep experience in leading government, military, intelligence community, and industry red teams provide us with deep understanding of the adversaries’ motivations and actions from many points of view. We combine this with our experience leading breach response and recovery for hundreds of incidents. We provide real-world experience and context of specific threat tradecraft across our client engagements to generate outcomes that counter these same threat actors.
