Expert Microsoft 365 consulting: security hardening, SharePoint setup, Power Platform automation & managed IT support.
A Microsoft-native partner — we build only inside the stack you already pay for.
Sound familiar?
Almost every Microsoft 365 tenant we open has the same handful of problems. See how many you recognise.
Every one of these is fixable with licences you already hold.
Tiers and seats billed every month, never switched on.
No MFA baseline, no conditional access, no idea who can reach what.
Attachments, personal OneDrives, an old file server. Nobody trusts the current version.
No named contact, no response times, every issue explained from scratch.
Approvals, onboarding and reporting still done by hand.
No adoption numbers, no security posture — just a monthly invoice.
Fantastic to work with on our migration project — smooth and stress-free.

We own the environment day to day — monitoring, governance, joiners and leavers, and a named helpdesk team that already knows your setup.
Power Platform automation, live Power BI dashboards, and a tenant genuinely ready for Copilot. We take the repetitive work off your team.

Why MStack360
No third-party sprawl, no reselling someone else's platform. Everything we build lives in the tenant you already pay for.
No third-party sprawl — we work in the stack you already pay for.
Scoped in days, delivered in weeks, not quarters.
Start at your level, move up when the business needs it.
Zero Trust is the baseline, not an upsell.
A named team who already knows your tenant.
We stay past go-live, because environments drift.
Free — no commitment
We open your tenant, look at what you're paying for against what's actually configured, and tell you plainly where the gaps are. No sales deck, no obligation — you keep the findings either way.
