Microsoft SentinelInvestigation & Response
Incident investigation, hunting, and response — accelerated by AI.
Microsoft Sentinel Investigation & Response gives analysts the tools to investigate incidents and respond fast — visual investigation graphs, entity behaviour, advanced hunting, and generative-AI assistance through Security Copilot — so an incident is understood and contained quickly. Faltrox operates the investigation-and-response function of a managed SOC.
Overview
What Investigation & Response is
Detecting a threat is only half the job — a SOC is measured by how fast it understands and contains an incident. Microsoft Sentinel’s Investigation & Response capabilities are built to compress that time: rich incident context, visual investigation, hunting, and AI assistance turn scattered alerts into an understood, contained incident.
It provides correlated incidents with full context, visual investigation graphs that map the entities and events of an attack, entity behaviour and timelines, advanced hunting to proactively search, and generative-AI assistance through Security Copilot that summarises incidents, explains artifacts, and recommends response. Response actions and automation contain and remediate threats. Faltrox operates the investigation-and-response function of the managed SOC it runs.

FAQ
Common questions
01What does the investigation experience provide?
Correlated incidents with full context, visual investigation graphs that map the entities and events of an attack, entity behaviour and timelines, and advanced hunting — so analysts understand what happened quickly rather than piecing it together from scattered alerts.
02How does Security Copilot help investigation?
It provides generative-AI assistance that summarises incidents, explains scripts and artifacts, and recommends response steps — accelerating investigation for analysts of any level and reducing the time to understand and contain an incident.
03Can we hunt proactively, not just react?
Yes — advanced hunting lets analysts write queries to proactively search security data for related, hidden, or suspected activity, rather than only reacting to alerts. Faltrox runs proactive hunting as part of the SOC.
04How does response work?
Response actions and automation contain and remediate threats — isolating devices, disabling accounts, and running playbooks — directly from the investigation, so understanding and containment happen in one flow.
05How does Faltrox operate it?
We run investigation and response as the core function of the managed SOC we deliver — triaging incidents, investigating with graphs and Copilot, hunting proactively, and executing containment and remediation on your behalf.
