Distributed firms, shared accountability
Independent offices need local control. Enterprise leadership still needs a reliable way to see material posture, exceptions, and follow-through across the network.
Regulated Financial Services
MCIT helps broker-dealers, RIAs, hybrid firms, and independent practices standardize Microsoft 365 security operations, delegated access, and reviewable evidence across separate tenants—with Microsoft 365 Lighthouse at the core.
The Executive Question
A compliance operating plane answers with a shared governance model, scoped technical delegation, and evidence-ready operations while preserving separate firm environments.
Independent offices need local control. Enterprise leadership still needs a reliable way to see material posture, exceptions, and follow-through across the network.
Cybersecurity, third-party oversight, customer-information safeguards, communications, and evidence production all depend on technology that can be governed and demonstrated.
AI use cases can touch supervision, communications, recordkeeping, privacy, and fair dealing. Firms need an approval and monitoring model before agents gain sensitive data or authority.
Reference Architecture
Microsoft 365 Lighthouse anchors the multi-tenant control plane. MCIT surrounds it with responsibility mapping, service operations, evidence discipline, recordkeeping boundaries, and AI governance.
Lighthouse baselines, audit logs, and posture views support operations; they do not replace compliant communications archiving, regulatory record production, supervisory review systems, or legal advice.
Six Connected Capabilities
MCIT connects the Microsoft layer to the operating disciplines a regulated firm needs to make decisions, manage exceptions, and prove follow-through.
Map roles, MFA, privileged access, GDAP relationships, support groups, expiration, and offboarding to least-privilege operating tasks.
Establish repeatable Microsoft 365 security baselines, deployment journeys, exception ownership, and reviewable drift follow-through.
Coordinate device, user, email, vulnerability, service-health, escalation, containment, recovery, and evidence workflows.
Inventory regulated channels, connect the approved archive and retention architecture, test production, and keep Lighthouse logs in their proper supporting role.
Operationalize vendor inventory, access reviews, contractual control evidence, incident exercises, contingency planning, and secure termination.
Gate use cases through data classification, approval, testing, model and action traceability, human review, monitoring, and retirement.
Responsibility by Design
This responsibility map is a starting point for the pilot charter. Final allocation must reflect the firm’s legal structure, supervisory system, agreements, policies, and actual services.

The architecture supports technical control operation and evidence. Each firm must determine which rules apply and whether its full supervisory, privacy, communications, and recordkeeping program meets them.
Support a reasonably designed supervisory system with named ownership, approved use cases, documented controls, testing, monitoring, and human review. Technology remains subject to the firm’s supervisory procedures.

FINRA’s 2026 report emphasizes that existing obligations remain technology-neutral and highlights governance, testing, monitoring, data sensitivity, model and action traceability, and human oversight.
Name the use case, owner, users, data, model, vendor, decision impact, and recordkeeping implications.
Apply data tiers, access boundaries, prohibited uses, required retention, and human-review thresholds.
Evaluate privacy, integrity, reliability, accuracy, bias, failure modes, and escalation behavior before release.
Track model versions, prompts or actions where required, approvals, exceptions, and human intervention.
Monitor performance and access, re-approve material change, and retire workflows that no longer meet the control case.
Pilot Before Portfolio
A bounded two-to-five-firm pilot makes differences visible early, validates the operating model, and gives executive leadership a real scale decision rather than a platform demo.

Decision FAQ
Clear boundaries make the pilot safer, faster, and easier to evaluate.
It is a shared technology-governance and evidence model that connects an enterprise control baseline to separately owned firm environments. It gives leadership consistent visibility and operating discipline while preserving each firm’s tenant, data, local decisions, and approved exceptions.
No. Lighthouse can support standardized configuration, multi-tenant visibility, scoped delegated administration, and operational evidence. Compliance depends on the firm’s facts, supervisory system, policies, recordkeeping architecture, implementation, testing, and legal and compliance advice.
Yes. The intended model keeps each customer tenant separate. MCIT operates through explicitly approved and scoped delegated relationships, subject to Microsoft eligibility and licensing requirements. The customer controls the relationship and can remove delegated access.
No. Lighthouse audit and operational data can support evidence, but it is not a FINRA Rule 4511 or SEC Rule 17a-4 archive. Regulated records need a separately designed retention, immutability or audit-trail, accessibility, and production architecture.
It creates the prerequisites AI governance depends on: identity, data classification, approved tools, responsibility, testing, logging and traceability, monitoring, human review, exception handling, and a controlled path to retire or expand a use case.
Start with a bounded pilot across two to five representative firms after agreeing on scope, responsibility, access, evidence, success measures, and stop conditions. Use a formal scale-gate review before adding the next wave.
