Competitive landscape
Edge: Lookout built one of the largest mobile threat intelligence datasets early — before Microsoft Intune and CrowdStrike added mobile modules. a16z's 2011 Series D lead validated mobile as a standalone security category.
Mobile security became table stakes inside broader endpoint platforms. Lookout survives on mobile depth and government contracts where specialized MTD still wins RFPs against bundled suites.
