Microsoft 365 security review
Review your tenant security posture across Microsoft Defender, Entra, conditional access, MFA, and Secure Score — and identify the gaps that matter most.
Microsoft 365 is a business platform — not just email and Teams. It carries your identity, your data, your collaboration, your endpoints, and increasingly your AI. Mycelium 365 helps you make sure it is secure, well governed, commercially right-sized, and ready for what comes next.
Security by Design, People First..Always.
A practical Microsoft 365 advisory review covering security, governance, licensing, identity, endpoint, data, collaboration, adoption, and Copilot readiness.
Review your tenant security posture across Microsoft Defender, Entra, conditional access, MFA, and Secure Score — and identify the gaps that matter most.
Assess how Teams, SharePoint, OneDrive, and Microsoft 365 Groups are provisioned, owned, and lifecycle-managed across your organisation.
Right-size your licensing across Business, Enterprise, and add-on SKUs so you stop paying for features you do not use and unlock those you already own.
Review identity hygiene, privileged access, guest access, conditional access, and sign-in risk so identity stops being the weakest link.
Check how Windows, macOS, iOS, and Android devices are enrolled, configured, and protected — and align endpoint controls with your security model.
Review collaboration sprawl, external sharing, sensitivity labels, and information architecture so people can find and share content safely.
Review data classification, retention, DLP, and sensitivity labelling so the right information is protected, retained, and discoverable.
Assess identity, data, permissions, and governance foundations before Copilot is rolled out — so AI does not expose what it should not see.
Review how people actually use Microsoft 365 day-to-day, where friction sits, and where adoption work will unlock real value.
Every engagement is designed to give you something useful you can act on — even if you choose not to proceed with implementation.
Microsoft 365 advisory services suit organisations that already use Microsoft 365 and want a mature, independent view of where it stands.
You have Microsoft 365 in place but are not confident it is secure, governed, or being used to its full potential.
You want an independent view of licensing value, risk exposure, and where the next investment should go.
You are being asked about Microsoft 365 Copilot and need to know if your data, identity, and governance are ready.
You need a mature, security-led view of Microsoft 365 risk, governance, and compliance posture — without the hype.
A clear, staged Microsoft 365 advisory process — from discovery, through review and roadmap, to optimisation and uplift.
We discuss your business, your Microsoft 365 environment, and what is prompting the review — security, cost, Copilot, governance, or all of the above.
We assess your tenant across security, identity, endpoint, data, collaboration, licensing, and AI readiness — using your real configuration, not assumptions.
You receive a prioritised set of findings, commercial recommendations, governance guidance, and a clear implementation pathway.
If you choose to proceed, we help deliver the security, governance, licensing, and adoption uplift — with your team or alongside your existing partners.
What organisations typically see from a structured Microsoft 365 advisory engagement.
Identity, endpoint, data, and collaboration risks are surfaced and addressed in a deliberate, prioritised way.
You stop paying for capability you do not use and start using capability you have already paid for.
Microsoft 365 Copilot and AI workloads are introduced on top of governed data, clean identity, and proper permissions.
Collaboration is clearer, adoption is higher, and Microsoft 365 actually supports the way your teams work.
Microsoft 365 advisory sits alongside our broader advisory, security, identity, and endpoint services.
