Local admin is the unlocked door.
Most ransomware doesn't need a zero-day. It needs a user with administrator rights and a moment of distraction. The right answer—take admin away from everyone—has been hard to deploy because removing admin breaks legitimate elevation needs: the QuickBooks update, the AutoCAD installer, the line-of-business app that touches%ProgramFiles% on every launch.
Lavawall® Application Elevation makes per-application the default unit of permission, not per-user. You build a list of what's allowed, you ringfence what's powerful, and you let your console approve everything else. Your users keep working. Your endpoints stop being the unlocked door.
