Microsoft 365 governance: build it or buy it?

Written by Rayna O'Neil | Jun 17, 2026 6:36:08 PM

Microsoft 365 governance is the set of policies, roles, and controls that decide how Teams, SharePoint, OneDrive, and the rest of your tenant get created, secured, and retired. For years, the prevailing wisdom in large enterprises was simple: if you had the resources, you built it yourself.

You control it. You tailor it to your environment. You build the fortress high, and it's yours to defend.

Plenty of organizations did exactly that. They poured real time and real talent into internal frameworks built to protect the enterprise. At the time, it made complete sense.

But the context has changed. The build-it-yourself instinct that once signaled strength now quietly creates drag, and more IT leaders are asking whether governance is still something worth owning in-house at all.

The pace of change is no longer linear

Microsoft is evolving continuously: new security models, new collaboration patterns, AI woven into everyday work. The platform isn't static, and internal tools built even three to five years ago are now in a constant state of catch-up.

Microsoft's own guidance treats governance as a living system of rules, practices, and processes an organization continually directs and controls, not a one-time configuration you stand up and walk away from. That distinction is where homegrown tooling struggles.

What I'm seeing across enterprises isn't a lack of capability. These are smart, well-funded teams facing operational drag. Scripts need updating, APIs shift, governance logic needs rework, and the architects who built the original system are moving on while the documentation falls behind reality.

The fortress still stands. But maintaining it consumes more and more energy that could go elsewhere.

When building your own Microsoft 365 governance starts to add risk

There's a harder conversation underneath the maintenance one. Many cybersecurity committees were built on a single principle: tighter control equals lower risk.

Build it yourself, lock it down, own everything. That made sense when change was slower and perimeter thinking still held.

Today, collaboration is fluid and external sharing is normal. Business units expect speed, and AI sits inside everyday workflows. In that environment, a rigid, internally built system can create the very risk it was meant to prevent.

Users route around the sanctioned path when it's too slow. Shadow IT grows quietly, sharing happens outside governed processes, and governance is left reacting instead of keeping pace.

And this holds regardless of which AI you put on top of the tenant. Copilot, Claude, or anything else inherits the same gaps a slow governance layer leaves open.

Security that can't keep up with the business eventually gets bypassed. The team didn't fail. Legacy architecture simply can't move at the speed the business now runs at.

This was never really about cost

If you're a chief information officer (CIO) trying to shift this conversation internally, the framing matters. The case for handing off the build rests on velocity, resilience, and enabling the business securely at the speed it now operates, not on cutting costs or headcount, and not on conceding the original strategy was wrong.

The language I hear resonating in executive and security discussions has a consistent thread. Leaders say their differentiation comes from how securely and quickly they enable the business, not from maintaining governance code. They want to keep owning policy and strategy while handing off the plumbing that enforces it.

A platform whose entire job is staying aligned with Microsoft lowers their operational exposure. Security starts to look less like restriction and more like enablement at speed. That moves the discussion away from buy-versus-build as a budget line and toward where the team's attention should actually go.

Build vs buy Microsoft 365 governance, side by side

When the decision is laid out plainly, the trade-offs get clearer. Your team is clearly capable; the real question is where their effort earns the most return.

  Build it yourself Buy a platform like Orchestry
Keeping pace with Microsoft Your team re-codes against every API and feature change Staying aligned with Microsoft is the platform's primary job
Maintenance burden Scripts, logic, and docs decay as architects move on Updates ship continuously, without your team's effort
Risk as the tenant changes Rigid rules get bypassed; shadow IT grows Oversharing detection and workspace review surface risk automatically
Speed to adapt Reactive; change requests queue behind other work Proactive; governance posture updates as the platform does
Where the team's energy goes Maintaining the plumbing Owning policy and strategy

Letting go is a strategic upgrade

The most forward-looking IT leaders I speak with aren't abandoning security. They're modernizing how it's delivered. This is where a purpose-built platform like Orchestry changes the equation: tracking Microsoft's changes is its primary job, not one more item on a stretched team's list.

In practice, that looks like:

  • provisioning templates and delegated lifecycle workflows that evolve as collaboration patterns do
  • oversharing detection and workspace review that surface risk without manual auditing
  • policy enforcement that updates proactively, not after something breaks

The scale of what teams are maintaining is easy to underestimate. Based on Orchestry data, 67% of workspaces show no activity in their first 90 days when Orchestry is first connected to a tenant, much of it governing space nobody is using.

Orchestry also reduces the dependency on institutional memory that quietly accumulates risk every time an architect leaves, while giving owners one consolidated view of every workspace instead of a pile of scripts.

Better experience. Faster enablement. Less operational strain on teams already stretched thin.

That's not compromise. It's maturity.

The real question: where not to build

Five years ago, building internally signaled strength. Today the stronger signal is knowing where not to build, and redirecting that talent toward a governance model people actually follow.

If your governance tooling needs constant defensive maintenance just to stay current, it's worth asking. Are you protecting your environment? Or are you protecting an old decision?

If the answer sits somewhere in the middle, you're in good company.

Build vs buy Microsoft 365 governance: common questions

Should you build or buy Microsoft 365 governance?

Buy, in most enterprise cases, unless governance is a genuine source of competitive differentiation for your organization. Building gives you full control but commits your team to perpetual maintenance against a platform that changes constantly. Buying a purpose-built platform shifts that upkeep to a vendor whose primary job is staying aligned with Microsoft, freeing your team to own policy and strategy.

What does it cost to maintain a custom Microsoft 365 governance solution?

The visible cost is the engineering time to build it; the hidden cost is everything after. Scripts and logic need reworking with each Microsoft change, documentation drifts, and knowledge walks out the door when the original architects leave. That ongoing maintenance, plus the risk that accumulates when it lags, is usually larger than the upfront build.

When does building your own Microsoft 365 governance make sense?

Building makes sense when your requirements are so specific that no platform can meet them, and when you have dedicated, durable engineering capacity to maintain the system indefinitely. For most organizations, governance is essential but not differentiating, which is exactly the profile where buying wins.

Does buying a governance platform mean giving up control?

No. You keep owning policy, standards, and strategy; what you hand off is the plumbing that enforces them. A platform like Orchestry runs your rules and keeps them aligned with Microsoft's changes, so control over the decisions stays with you while the maintenance burden does not.
