Can we buy Copilot and fix security later?

You can — but every day Copilot is on, it indexes accessible content. Fixing overshared libraries after rollout is harder than readiness first. Most insurers and enterprise clients expect baseline identity controls before AI expansion.

How long does Copilot readiness take?

FC-19 is delivered in five business days with 50% on booking. Remediation of findings may extend into M365 hardening or a Copilot Studio sprint — scoped separately.

Does Copilot readiness include user training?

FC-19 includes rollout order and pilot recommendations. Hands-on training can be added; the package focuses on tenant safety and governance before seats go live.

M365 Copilot readiness checklist: what to fix before seats go live

Copilot indexes what your permissions already expose. Before you assign licences, run through SharePoint boundaries, admin hygiene, MFA, and data classification — or you risk oversharing at machine speed.

MSPs sell Copilot seats because Microsoft incentivises it. Few pause to map what Copilot will actually retrieve when someone asks about "our pricing" or "client contracts." If SharePoint sites are open to Everyone, Copilot will summarise exactly that — faster than any human could search.

Readiness is not a licence discussion. It is a data boundary, identity, and governance discussion. The checklist below is what we run in FC-19 M365 Copilot Readiness — fixed price, five business days, deliverable you can hand to the board.

SharePoint and Teams exposure

Inventory sites with broad access, stale "Everyone except external" links, and document libraries that grew organically for ten years. Purview sensitivity labels and DLP policies should match how you actually classify client vs internal data.

Identify libraries that must be excluded from Copilot scope until cleanup — better a phased rollout than a headline about AI leaking tenders or HR files.

Identity and admin hygiene

No daily-driver Global Admin accounts. MFA enforced for all admins and users via Conditional Access — not optional per-user settings. Legacy auth disabled.

Review guest access and external sharing defaults. Copilot respects permissions — but broken permissions become AI-scale problems.

Rollout order and pilot group

Start with a pilot group that understands prompt hygiene and can report bad retrievals. Train on what Copilot is for (draft, summarise in M365) vs what it is not (authoritative legal or financial advice).

Document phased rollout: which workloads, which departments, success metrics, and rollback if oversharing is detected.

Fixed-price readiness package

FC-19 delivers a data boundary map, Purview and permissions review, admin/MFA baseline findings, and phased rollout order. FC-27 combines FC-19 with FC-04 M365 Security Baseline for teams about to buy seats.
