Xcitium, a leader in prevention-first cybersecurity, today announced the launch of Xcitium Managed EDR for Microsoft Defender, a purpose-built solution designed for organizations that rely on Microsoft Defender and require stronger protection, continuous ownership, and predictable security outcomes.
Built to complement Microsoft Defender, Xcitium Managed EDR transforms detection-driven environments into prevention-first security operations by introducing ZeroDwell containment, continuous SOC ownership, and integrated free breach response.
Microsoft Defender is widely trusted as a foundational security platform across enterprises and mid-market organizations. However, alerts and telemetry alone do not prevent breaches. Detection provides visibility, but security outcomes depend on ownership.
When alerts trigger, they must be investigated. When suspicious activity appears, it must be contained. When incidents escalate, they must be resolved.
In many environments, responsibility remains fragmented across teams and tools. This fragmentation creates delays that allow threats to persist and expand.
Xcitium Managed EDR introduces continuous ownership into Microsoft Defender environments, ensuring that alerts are not only detected but actively investigated, contained, and resolved.
Traditional endpoint security approaches detect threats after execution. Xcitium shifts the model from detection to prevention through its patented ZeroDwell containment architecture.
Unknown files are allowed to execute safely within virtualization, preventing interaction with production systems while enabling real-time behavioral analysis.
By isolating suspicious activity at the kernel level, Xcitium removes the dwell time that attackers rely on to establish persistence and move laterally.
This containment-first approach neutralizes unknown threats without disrupting workflows or requiring changes to existing Defender deployments.
Xcitium Managed EDR includes continuous, human-led SOC ownership that assumes responsibility for threat investigation and response.
Security analysts monitor Defender telemetry around the clock and validate every alert. This ensures that real threats are identified quickly while unnecessary noise is reduced.
When incidents occur, containment actions begin immediately, and remediation continues through resolution.
Whether an alert occurs during working hours or overnight, response of ownership remains consistent.
Many security providers treat breach response as a separate, high-cost engagement that is activated only after an incident occurs.
Xcitium takes a different approach.
Xcitium Managed EDR includes breach response as part of the service. Organizations can act immediately without retainers, emergency contracts, or usage-based charges.
This ensures that response is available from the moment an incident begins, enabling faster containment and recovery without introducing financial uncertainty.
Xcitium Managed EDR integrates directly with existing Microsoft Defender deployments, including Microsoft Defender antivirus and Defender for Endpoint.
Organizations retain their Microsoft security investments while gaining prevention-first protection and continuous operational ownership.
Deployment does not require replacing tools or modifying infrastructure.
“Microsoft Defender provides powerful visibility into threats, but visibility alone does not stop attacks”
With Xcitium Managed EDR for Microsoft Defender, organizations gain prevention-first protection, continuous SOC ownership, containment-driven response, and integrated breach readiness.
This enables security teams to move from reactive alert management to proactive outcome ownership.
Xcitium Managed EDR for Microsoft Defender is available immediately.
