A Leading Retail Group Activates Microsoft 365 Security Across Its Retail Portfolio

One of Australia’s most recognised retail groups operates a portfolio of iconic brands across fashion, footwear, and lifestyle categories. With multiple business units, a seasonal retail workforce, and a distributed corporate and store footprint, the organisation relies on Microsoft 365 as the productivity and security backbone of its operations.

Challenges

Security tooling and identity controls had grown inconsistently across a portfolio of well-known retail brands, leaving the organisation with limited central visibility and significant under-utilisation of capability already paid for in Microsoft 365. Different endpoint, email, and identity products were in use across business units, making it difficult to correlate a security incident across the group.

There was no single console giving central security teams a unified threat picture, and incident response was slow and fragmented. Microsoft 365 licensing included significant security capability that had not yet been turned on, meaning the organisation was paying for entitlements it was not consuming. A seasonal retail workforce with frequent joiner, mover, and leaver events further elevated identity risk, with MFA coverage and Conditional Access inconsistently enforced.

Solution

Oreta uplifted the Microsoft 365 security stack across the retail portfolio with a clear principle: turn on entitled capability rather than buying more tools. Microsoft Defender for Endpoint, Defender for Office 365, and Defender for Cloud Apps were deployed as the unified threat console, with detection policies tuned to the retail risk profile.

Endpoint management was standardised on Microsoft Intune, with compliance baselines, application control, and modern enrolment applied consistently across the portfolio. Entra ID Conditional Access and phishing-resistant MFA were implemented across all corporate users, with tighter policies for high-risk identities and privileged roles. The end result was a unified, defensible posture built on entitlements already in place.

Outcome

• Existing Microsoft 365 licensing converted into delivered security outcomes, with no new third-party tooling required.
• A single Defender console providing unified threat protection across endpoint, email, and cloud apps.
• Microsoft Intune established as the single endpoint management baseline across the portfolio.
• Entra ID Conditional Access and phishing-resistant MFA enforced across all corporate users.
