For UK SMEs dealing with hybrid work, SaaS sprawl, and ransomware threats, combining both can significantly reduce blast radius after a compromise. The guide covers practical design principles including least privilege, default deny, and path separation for admin/user/service traffic. It recommends starting with a trust and traffic model, piloting on one high-value application, and expanding in phases. Reference architectures include identity-centric designs using Microsoft Entra ID, agent-based vs. network-based segmentation, and handling mixed cloud/on-premises/SaaS environments. Operational visibility through logs, SIEM/XDR telemetry, and policy validation is emphasized, along with a pragmatic 90-day roadmap. ## Full article daily.dev links to this article rather than hosting it.
