Microsoft has published insights from its 2026 Digital Defense Report, arguing that defenders need to connect signals across endpoints, identities, cloud environments, applications, email, networks, and threat intelligence.
The company’s framing focuses on the operational value of treating those data sources as a joined picture rather than isolated alerts. For security teams, that reinforces the importance of cross-domain investigation workflows, normalized telemetry, and clear ownership for identity and cloud signals alongside endpoint data.
Takeaway for defenders
Use incident reviews to identify where detection or response lost context between security domains, then prioritize integrations and playbooks that preserve that context.
