We strive to offer clients actionable assessments that go beyond the obvious and offer implications of geopolitical events in the regions they operate.

Our flagship product, the World Risk Register, provides both written and quantifiable analysis on world events, by region. Our proprietary software gives clients the ability to gain any level numerical data on world-wide locations as needed, in tandem with an overall rating system and backed up by written analysis with predictions of how events will unfold and impact business.

Our services and experience include fully-run in-house GSOCs, virtual GSOCs, embedded analysts, consultation and training for existing security operations with insight for improvement, project work, regular reporting, social media monitoring and due diligence services.

As subject matter experts, our analysts are frequently called upon for speaking engagements, media interviews and in-house corporate presentations.
