Defender & MDO cross-suite

Security stacks overlap—CHAOS shows overlap and gaps.

Problem

Organisations buy Defender add-ons while E5 already covers—or the opposite. MDO plans intersect with third parties. Security wants no gap; finance wants no duplication. Manual matrices go stale fast.

Approach with CHAOS

CHAOS models suite content vs add-ons vs third-party coverage (where rules can express it) and flags redundancy or gaps. Decisions are documented in the Why-layer. Pilot groups test policy impact.

Outcome from CHAOS

Leaner security licence stack, clearer SOC vs licensing ownership, and defensible explanation to audit. Savings without blindly stripping critical controls.

Insight

Security purchases are emotional—only evidence-based curves convince the CFO without a “we risk everything” narrative.
