Base Operations improved our executive security posture by enabling us to proactively identify threats and adjust security measures in both existing, remodeled, or newly acquired residential properties for senior executives. Nearby residential high net worth burglaries and break ins could have been a wake-up call too late. Instead, it became an opportunity to demonstrate the value of data-driven security planning.
Street level intelligence for EP teams is an absolute game-changer. If you're not aware of what this is, the implications, and how this benefits large full scope enterprise teams as well as individual operators, you're behind the curve. I highly recommend folks in the EP space check out Base Operations. Over the last 5+ years, the level of data collected, ingested and analyzed is nothing short of extremely impressive.
Base Operations informs our strategic and routine security planning across the world. The unmatched granularity of micro-intelligence supports our supply chain security planning and dramatically improves our travel security guidance.
