Most incidents start with something avoidable.
A setting that drifted. A policy left in report-only. A sharing default nobody revisited. Defend 365 exists to find those before an attacker does.
Prevention-first
Detection is necessary. It is not the beginning.
Detection and response exist because something already went wrong. Prevention is cheaper, quieter and measurable. Defend 365 continuously tests Microsoft 365 configuration against 700+ checks, watches for drift, and prioritizes what actually widens your exposure. We reduce preventable exposure. We do not claim to remove risk entirely, and we do not replace a SOC or MDR service.
The gap we close
Knowing about a risk is not the same as resolving it.
Posture tools have always been good at producing lists. Teams stall at the next step: what to fix first, whether it is safe to automate, and who should do the work when nobody in the building has done it before. That is why Defend 365 pairs continuous testing with SIA for context, automation for the safe changes, and Defenders for the work that genuinely needs a specialist.
Defenders
Software plus screened human expertise.
Defenders is a curated network of Microsoft security specialists inside the Defend 365 ecosystem. Experts do not sign up and start selling. Every Defender is screened before they can offer services through the platform, and every engagement starts from a scope the product defined — a finding, a cluster, or a whole framework.
How we build
Product-led, opinionated, continuously updated.
Microsoft 365 changes constantly, so the Defend 365 Baseline changes with it. New services, new attack paths and new defaults become new tests. Onboarding stays self-service and takes minutes, because a security tool that needs a project before it produces value does not get used.
