Xcitium Managed EDR for Microsoft Defender

Turn Microsoft Defender into a prevention-driven outcome with 24×7 SOC, ZeroDwell protection that allows unknowns to run safely through virtualization, and included incident response at no cost without replacing your Defender investment.

Managed EDR Xcitium
Detection Without Ownership Creates Risk
Microsoft Defender generates alerts, but without continuous ownership, no one is accountable to investigate, contain, and resolve threats immediately.
Detection Dependency

Microsoft Defender antivirus detects threats post-execution, allowing attackers lateral movement and expansion.

Ownership Gap

Alert response depends on internal availability, creating uncertainty about who validates, contains, and resolves incidents.

After-Hours Exposure

When alerts trigger outside business hours, incidents wait uninvestigated, allowing attackers time to escalate.

Operational Overload

IT teams become reactive responders, managing alerts manually while balancing critical operational responsibilities.

Prevention-First Security That Eliminates Dwell Time

Xcitium completes Microsoft Defender by adding ZeroDwell virtualization, prevention-first protection, and full ownership of security outcomes.

Safe Execution

Unknown threats run safely inside virtualization, preventing persistence, lateral movement, or interaction with production systems.

Instant Isolation

Kernel-level virtualization isolates suspicious activity immediately, eliminating attacker dwell time and limiting breach exposure.

Preemptive Protection

Behavioral analysis occurs during execution, allowing threats to be neutralized before operational impact occurs.

Ownership Transfer

Xcitium assumes complete responsibility for investigation, virtualization, remediation, and resolution without internal escalation or handoffs.

Breach Response

Integrated no-cost breach response ensures incidents are handled immediately without external contracts or delays.

Unified Intelligence

Correlated telemetry from endpoint, identity, and cloud sources delivers actionable insights and faster threat response.
