Explore Warden SOC →What does zero-dwell endpoint protection actually change?
Warden is zero-trust endpoint protection that stops unknown files before they execute: Kernel API Virtualization auto-contains every unknown at the kernel boundary in 1–2 milliseconds, so there is no detection to fire and no alert queue to triage. The trade is real — prevention-first forgoes the forensic timeline a detect-and-respond EDR gives you. It fits organizations with no SOC or small IT teams, roughly the 10–500 endpoint reality. If you already staff analysts for hunting and want deep telemetry, detect-and-respond fits better. Disclosure: CSI resells Warden, built on Xcitium ZeroDwell.
By the time a detection engine fires, the unknown has executed, written to disk, and started moving. Everything after that is cleanup. Warden removes the window entirely.
Zero trust endpoint protection at the kernel boundary.
Every unknown process runs inside a lightweight virtual container with its own copy of the file system, registry, and COM interfaces. It believes it has full access. It touches nothing real. Verdict in milliseconds — allow, or discard with zero residue.
Auto-Containment
Unknowns are virtualized automatically — no analyst decision, no quarantine queue. Unknown files are isolated before execution on protected endpoints.
Zero Dwell Time
Containment happens in 1–2 milliseconds at the kernel API layer — not after behavior is observed. There is no window for the threat to act.
No Signatures
Prevention does not depend on knowing the threat in advance. Zero-days and novel ransomware are contained the same way as anything else — by default.
Deploys in Minutes
Runs alongside your existing antivirus with zero disruption. No SOC required — protection is silent and automatic from the first endpoint.
Warden is the prevention layer of CSI’s AI security solutions stack — the same architecture that governs autonomous agents under the AI governance framework.
Three ways to handle an unknown file. One produces certainty.
| Scenario | Signature AV | Detection EDR | Warden CSI |
|---|---|---|---|
| Unknown / zero-day malware | × Novel files execute | · Alert after execution | ✓ Isolated before first instruction |
| Dwell time | × Until signature ships | · Minutes to hours | ✓ 1–2 milliseconds |
| Analyst alert load | · Low signal, high miss | × High — alert fatigue | ✓ Near zero — auto-contained |
| SOC / expert required | · Minimal but blind | × Required | ✓ Not required |
| Audit evidence | × Sparse logs | · Post-event reconstruction | ✓ Full containment record |

Prevention-first is not a claim. It is a track record.
Where zero dwell time matters most.
Dwell time is not a threat-level problem. It is a cost problem. Every minute an unknown file sits on an endpoint is a minute of analyst triage, audit exposure, and regulator questions.
The environments below are where that cost compounds fastest: small security teams facing ransomware, healthcare teams protecting PHI, defense and CUI environments under CMMC, and vessels where OT, bridge, and crew networks share one flat pipe.
In each, prevention buys the same thing: a clean containment record with no alert queue to staff.

Maritime Security →Common questions about Warden.
How is this different from the EDR I already run?+
Detection-based EDR watches for malicious behavior and alerts after a process begins executing. Warden never lets an unknown execute on the real system in the first place — it runs inside Kernel API Virtualization until proven safe. Prevention instead of response.
Do I need a SOC or security analysts to run it?+
No. Containment is automatic and silent. Because unknowns are isolated by architecture rather than triaged by a person, there is no alert queue to staff. Most teams deploy it without adding headcount.
Will it conflict with my existing antivirus?+
No. Warden is designed to run alongside your current AV with zero disruption, adding a prevention layer underneath the tools you already have. Deployment is typically same-day.
What happens to a file that turns out to be legitimate?+
It runs normally. While a verdict is pending, the application operates inside the virtual container and the user sees no difference. Once cleared, it is released to the real system — no false-positive ticket, no blocked work.
What does "zero infections since October 2020" actually mean?+
Across Xcitium platform deployments running this containment architecture, no endpoint has been successfully infected since October 2020 — true of Xcitium platform deployments as of October 2026. Unknowns are contained by default, so novel and zero-day threats are handled the same way as everything else.
Is Warden right for us if we are not a large enterprise?+
Yes — it is built for the 10–500 endpoint reality, not just enterprises with 24/7 security teams. If you have unlimited SOC budget and analysts, detection tooling may suit you. If you want silent, automatic protection, Warden is the better fit.
