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.

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.
