Managed IT and Cyber Security Services for Organisations

Mycelium 365 runs the whole Microsoft environment as one managed service. Rather than stitching together a helpdesk vendor, a cloud partner and a security provider — each with a different view of your tenant — every service on this page is delivered by the same team, against the same standards, with a single point of accountability when something breaks.

The foundation is Microsoft 365: Exchange Online, SharePoint, Teams and OneDrive administered properly, with licensing reviewed so you are not paying for entitlements nobody uses. On top of that sits identity and device management through Microsoft Entra and Intune, which is where most real-world security outcomes are won — conditional access, phishing-resistant MFA, privileged access controls and compliant devices. Our security services extend that with a 24/7 security operations centre, managed Microsoft Defender, and Essential Eight aligned hardening backed by evidence your insurer or auditor will accept.

For infrastructure, we manage Azure end to end — subscriptions and cost governance, virtual machines, Azure Virtual Desktop, networking and gateways, storage, and backup with tested recovery. Migration work, whether from on-premises servers, Google Workspace or another provider's tenant, is planned and delivered by the same engineers who will support the result. And as AI moves from pilot to production, our AI and automation services govern Copilot rollouts, Power Platform sprawl and agentic workflows so the productivity gain does not arrive with a data exposure problem attached.

Everything is fixed price, month to month, with no lock-in contracts. Browse the full service directory below, or book a discovery call and we will map the right starting point.
