Case Study: How We Upgraded Security and Wi-Fi Reliability
The Challenge
The organisation required a full review of its technology landscape, with several key priorities:
- Consolidating files previously stored in Dropbox.
- Securing the company domain after years of unmanaged DNS records.
- Establishing a structured Microsoft 365 tenant.
- Ensuring email authentication standards (DMARC, DKIM, SPF) were correctly implemented.
- Providing a reliable platform that would scale with business growth.
Our Approach
We carried out a full architecture review and designed a structured plan covering discovery, design, implementation, and handover. Key activities included:
- Gaining access to the domain host and resolving legacy configuration issues.
- Adding the company domain to Microsoft 365 and preparing it for production use.
- Configuring a new SharePoint structure for secure shared file storage.
- Creating dedicated administrator accounts and enforcing MFA and modern security practices.
- Hardening meeting and collaboration settings, ensuring only trusted, invited users could join or present.
- Implementing DMARC, DKIM, and SPF, significantly improving protection against spoofing and phishing.
- Migrating the full Dropbox library to OneDrive, covering 48GB+ of data across more than 14,000 files.
- Setting up a shared postmaster mailbox for DMARC reporting and ongoing monitoring.
The Results
Within the space of a few weeks, the business moved from a loosely configured set of legacy tools to a fully governed Microsoft 365 environment aligned with modern best practice.
The outcomes included:
- A secure, fully operational Microsoft 365 tenant configured for long‑term use
- Improved data governance, with all files migrated into SharePoint and OneDrive
- Strengthened domain and email security, drastically reducing risk exposure
- Clear administrative separation, ensuring no day‑to‑day user retains elevated permissions
- Streamlined collaboration, with Teams and SharePoint configured consistently across the business
