Why it Matters?

Misconfigurations in Microsoft 365 are frequently exploited by attackers. Our Lite Review benchmarks your tenant against leading standards to reveal strengths, gaps and quick wins, without the cost or time of a full audit. 

Drawing on real-world incident response experience, our experts uncover the misconfigurations, privilege issues, and missed opportunities that attackers exploit most frequently.  

With clear, prioritised recommendations and an executive-ready summary, your teams gain the visibility they need to take immediate action. 

Whether you’re planning a broader security uplift or validating your existing setup, this service provides an essential foundation for continuous improvement and proactive defence across your Microsoft 365 environment.

Microsoft Defender Configuration

We assess your Microsoft Defender setup to ensure it’s aligned with ASD Essential Eight guidelines and core Microsoft security controls. Misconfigurations often create exploitable weaknesses that attackers can leverage to bypass detection or containment.

Our review identifies any gaps in Defender coverage, compares protected assets against your inventory, and highlights deviations from policy. 

You’ll receive practical, prioritised recommendations to optimise protection, close configuration gaps, and improve resilience.

This gives your security and IT teams a clear, actionable roadmap to strengthen Defender’s ability to detect, prevent, and respond to threats across your Microsoft 365 environment. 

Microsoft Secure Score Analysis

Microsoft Secure Score

Your Microsoft Secure Score provides a measurable baseline for your organisation’s security posture — but it’s only valuable if you know how to interpret and improve it.

We establish your baseline Secure Score, then pinpoint high-priority areas where remediation will have the greatest impact.

Each recommendation is tailored to your licensing tier and business needs, ensuring the improvements are achievable and cost-effective.

Our experts help you understand what your Secure Score means, how it compares to benchmarks, and where you can focus for maximum results.

The outcome: measurable improvement and ongoing visibility into your Microsoft 365 security maturity.

Unified Audit Log Review

Visibility is critical for detection and response. Our team verifies whether Unified Audit Logs are enabled across Exchange and Entra ID, and that all relevant activities are being recorded.

We assess retention settings, event coverage, and compliance alignment to ensure no critical gaps exist. Missing or misconfigured logs can hinder investigations and compliance reporting — we help you avoid that risk.

Our recommendations focus on achieving consistent, reliable logging across all key workloads, empowering your organisation with the visibility required to monitor activity, detect anomalies, and meet regulatory and audit obligations with confidence.

Licensing & Privileged Identity Management (PIM)

Licensing directly impacts security capability — and many organisations underuse what they already pay for.

We review your Microsoft 365 and Entra ID licensing to identify unused security features or gaps limiting protection.

Where Privileged Identity Management (PIM) is available, we evaluate configuration and role assignments to ensure least-privilege principles are applied.

Our experts highlight where privilege controls can be tightened, temporary access policies enforced, and licence upgrades might yield significant security benefit.

This ensures your Microsoft investment is maximised while maintaining strong governance, accountability, and reduced risk of privilege misuse or unauthorised escalation within your environment.

CIS Lite Configuration Review 

Using a tailored subset of the CIS Microsoft 365 benchmarks, our Lite Review flags critical configuration issues that may compromise your environment.

While not a full audit, this focused approach identifies the most impactful improvements your team can make immediately.

Each finding is risk-rated, with recommended next steps and clear remediation guidance. The process helps you understand how closely your setup aligns to industry frameworks, while avoiding the time and complexity of a full CIS audit. 

It’s a practical, efficient path to improving your Microsoft 365 posture and achieving stronger compliance with established security standards.
