The Challenge

Most cloud migrations are designed for speed. Security comes second.

Cloud migration without security controls baked in from the start is the norm, not the exception. Open storage accounts, overprivileged service principals, no Defender for Cloud, conditional access gaps, and misconfigured logging are standard findings in the Azure estates we assess. By the time someone audits the environment, you're remediating a hundred small decisions made under deployment pressure.

Azure's native security tooling is powerful — but it takes genuine expertise to configure Defender for Cloud correctly, build Sentinel detection rules that catch real threats, enforce Zero Trust identity policies without locking out your people, and keep the Secure Score moving in the right direction over time. A misconfigured tenant looks fine in the portal. Until it doesn't.

Common Questions

Frequently Asked Questions

We review your Azure environment against the Microsoft Cloud Adoption Framework (CAF) security guidance and CIS benchmarks, identify gaps, and implement controls to reduce your attack surface. It's not a theoretical audit — we fix things. You receive a findings report, a remediation plan, and completed implementation of the priority controls.

A focused Azure posture review typically runs two to three weeks: one week of discovery and assessment, one week of findings and prioritisation, one week for initial remediation on the critical items. Larger or more complex estates with multiple subscriptions, hybrid connectivity, or regulatory requirements take longer. We scope it precisely after your Ignite Assessment.

If you're running workloads in Azure, yes. Defender for Cloud gives you continuous posture assessment, threat detection across compute, containers, and storage, and regulatory compliance monitoring in one place. The default settings leave significant gaps — the real value comes from proper configuration of the protection plans and integration with Sentinel for alerting and response.

Defender for Cloud assesses your posture and detects threats at the workload level — compute, containers, databases, storage. Sentinel is your SIEM: it collects security signals from across your environment (Azure, M365, on-premises, third-party tools) and correlates them into incidents for investigation. They're complementary. Defender feeds signals into Sentinel; Sentinel gives you the full picture and the response playbooks.

Yes. We lead with Azure but have strong AWS security capability. We assess both environments, build controls that work across them, and integrate them into a unified view in Sentinel — particularly around identity federation, cross-cloud logging, and incident response. Microsoft Defender for Cloud also extends to AWS workloads, which we configure and manage.
