P1 Incident Management & Security Escalations

Rapid incident coordination and security escalation for Priority 1 events - triage, containment support, evidence capture, and clear communications until service is restored.

When a Priority 1 incident hits - ransomware suspicion, account compromise, mass phishing, critical service outage, or widespread device impact - time matters. Most P1 events become expensive because there is no single, structured incident process: evidence is scattered, actions are duplicated, and decisions are made without a clear view of impact. In Microsoft estates, P1 issues frequently cross workloads (Entra ID, Intune, Defender XDR, Exchange Online, SharePoint/OneDrive, Teams, Azure) and require disciplined coordination to contain risk and restore services safely.

LW IT Solutions provides P1 Incident Management & Security Escalations as an on-demand or retainer service to bring structure to high-severity incidents. We act as a senior escalation layer - running triage, coordinating technical workstreams, supporting containment actions, and capturing the evidence and decisions required for post-incident review. Where Microsoft security platforms are in use (for example, Microsoft Defender and/or Microsoft Sentinel), we work with your telemetry to speed diagnosis and reduce uncertainty. Where those platforms are not fully deployed, we operate within the available data and recommend targeted improvements to reduce recurrence.

Talk through your requirements and leave with a clear next-step plan.
