ZeroDwell containment endpoint security — unknown executables run in kernel-level virtualization, not on the actual endpoint. The differentiator isn't "better detection"; it's "prevention even when detection fails." Default-deny posture for unknown processes, with full process execution inside an isolated container until proven benign.
Xcitium's underlying technology is auto-containment — when an unknown executable runs on a protected endpoint, it executes inside a kernel-level virtualized container rather than on the actual endpoint. The container has access to a virtualized view of the file system, registry, and network. If the executable is benign, the user notices nothing. If it's malicious, the container is destroyed and the host is never affected. The pitch versus traditional EDR is structural: detection-based EDR assumes you can identify malicious behavior; containment assumes you can't always, and isolates first.
You've deployed CrowdStrike or SentinelOne and breaches still happen. The premise that you can always detect malicious behavior is failing. Containment is the architectural alternative.
Detection-based posture isn't enough when consequences of breach are extreme. ZeroDwell containment is the additional layer that makes "assume breach" actually defensible.
Switching costs are real. Brief Xcitium as a containment layer overlay rather than rip-and-replace, where their products support that pattern.
If your existing EDR is catching what matters, the containment premium isn't justified. Brief eSentire or Foresite for traditional MDR instead.
