Structured incident response and forensic triage to contain impact, preserve evidence, restore operations, and reduce the likelihood of repeat compromise.
Security incidents are rarely confined to a single system - identity, email, endpoints, cloud resources, and SaaS applications can all become part of the attack path. Effective incident response typically follows a lifecycle: preparation, detection and analysis, containment, eradication, recovery, and post‑incident improvement. Microsoft provides incident response guidance and playbooks designed for modern security operations teams, including practical steps for planning, execution, and continuous improvement.
LW IT Solutions provides incident response support that is built for real-world constraints: limited time, incomplete telemetry, and the need to maintain business continuity. We establish a clear command structure, preserve key evidence early, and execute containment actions under an agreed approval model. Where forensic triage is required, we focus on scoping impact and identifying attacker behaviour that informs safe eradication and recovery. We conclude with a prioritised hardening backlog across Microsoft 365, identity, endpoints, and cloud - so you get measurable improvement, not just incident closure.

Objectives & deliverables
What Success Looks Like
- Contain active threats quickly while protecting critical operations
- Understand what happened using evidence-led investigation
- Support safe recovery without reintroducing risk
- Provide clear documentation for governance and assurance
- Improve security posture based on lessons learned
What You Get
- Engagement plan: scope, roles, approvals, and decision log approach
- Investigation summary: findings (as evidenced), impact assessment, and actions taken
- Evidence pack: timeline, key artefacts/log references, and containment rationale
- Remediation backlog: prioritised actions with owners, dependencies, and sequencing
- Optional updated playbooks/runbooks for future readiness
How It Works
- Activate - agree scope, command structure, approvals, and communications
- Triage - analyse alerts and telemetry to scope impact and attack paths
- Contain - execute approved actions to stop spread and protect assets
- Investigate - perform forensic triage to identify behaviour and persistence
- Recover - support safe restoration and validate normal operations
- Improve - define and prioritise hardening actions across affected platforms
Engagement Options
- IR Readiness & Playbook Workshop (prepare roles, escalation, and playbooks)
- Rapid Triage Support (time-boxed investigation and containment plan)
- Incident Response Programme (triage, containment, recovery, improvement backlog)
- Post-Incident Hardening Sprint (implement key remediation actions with change control)
