Common questions

01How do you measure the improvement?
Every engagement is measured against Microsoft Secure Score. Typical uplift after a QG engagement is 30–50 percentage points, moving a tenant from a pre-engagement baseline of around 25–40% to above the 75th percentile of peer organisations. Progress is tracked quarterly.
02Do we need Microsoft E5?
Not necessarily. We guide clients to the optimal licence tier (Business Premium, E3 or E5, or a mixed-licence strategy) based on your scale and regulatory needs, so you buy the security you actually require.
03Which threats does this address?
We map specific Microsoft-native controls across Defender, Entra, Purview and Sentinel to real enterprise threats: credential phishing/AiTM, ransomware, insider data exfiltration, business email compromise, misconfigured sharing and privileged-account abuse.
