How it works

A running program, not a one-off project.

Mantle is a team of Microsoft 365 experts who look after your data security every month — finding what's sensitive, controlling who can see it, and keeping proof you're in good shape.

01 · Discover

Find your sensitive data

We go through your Microsoft 365 environment, email, and files to map exactly where sensitive and regulated data lives, and who can currently reach it.

02 · Govern

Lock down access & policy

We tighten permissions, remove risky sharing, and put labelling and DLP policies in place so the right people have the right access, nothing more.

03 · Prove

Stay audit-ready

We keep evidence, controls, and reporting current so you can answer auditors, customers, and regulators with confidence at any time.

04 · Adopt AI safely

Get ready for Copilot & AI

We clean up the oversharing and permissions problems that make AI risky, so you can turn on Copilot and other tools without leaking data.

Three ways to work with us

However hands-off you want to be.

Outsourced experts

You keep ownership; we act as your on-call data-security, governance, and compliance team behind the scenes.

Embedded team member

We work inside your stack and rituals like a colleague, attending standups, owning tickets, and driving the roadmap.

Fully managed

We take it off your hands entirely and run the whole program end-to-end, reporting outcomes to your leadership.

Onboarded in about two weeks.
