Microsoft Azure
Azure Security Services
Protect identities, networks, workloads and data on Microsoft Azure with controls that are designed in from the start, monitored continuously and improved every month.
Build Security into Your Azure Platform
Azure provides a deep set of native security services, but they do not configure themselves. Over-privileged accounts, public endpoints, missing Conditional Access policies and unreviewed Defender for Cloud recommendations are among the most common weaknesses in cloud environments. Under Microsoft’s shared responsibility model, these are the customer’s side of the line. Hanoi Technology helps you close those gaps with Microsoft Entra ID, Azure Policy, Microsoft Defender for Cloud, Microsoft Sentinel and network controls designed as one system.
We prioritize findings by real exposure rather than by alert count, fix them as code so they stay fixed, and set up monitoring and response processes your team can sustain. Our work follows the Microsoft cloud security benchmark and maps to frameworks such as ISO 27001 or SOC 2 where needed.
The Challenge
Security Challenges We See in Azure Environments
Most incidents stem from configuration and identity, not from exotic exploits.
Identity Is the New Perimeter
Standing administrator rights, legacy authentication, unmanaged guest accounts and long-lived service principal secrets give attackers easy paths into the tenant.
Too Many Alerts, Too Little Context
Defender for Cloud recommendations and Sentinel incidents pile up without prioritization, so important signals are lost among low-risk findings.
Inconsistent Network Controls
Public IP addresses, permissive network security groups and missing private endpoints expose databases and storage accounts directly to the internet.
Compliance Evidence Is Manual
Auditors ask for proof of controls, and teams spend weeks gathering screenshots instead of relying on policy compliance reports.
Business Value
Outcomes of a Well-Secured Azure Platform
Reduced Attack Surface
Private endpoints, Azure Firewall, web application firewalls and tightly scoped network rules limit what is reachable from the internet.
Least-Privilege Access
Microsoft Entra Privileged Identity Management, Conditional Access and managed identities replace standing admin rights and stored secrets.
Continuous Posture Visibility
Defender for Cloud secure score, attack path analysis and regulatory compliance dashboards show where you stand and what to fix next.
Faster Detection and Response
Microsoft Sentinel and Defender XDR correlate signals across identities, endpoints and cloud resources, with automated playbooks for routine actions.
Guardrails That Prevent Drift
Azure Policy blocks non-compliant deployments and remediates settings automatically, so new resources start secure.
Audit-Ready Evidence
Policy compliance and Defender regulatory reports provide continuous evidence for internal and external audits.
Prevention Beats Detection, but You Need Both
Strong identity and policy guardrails stop most attacks before they start. Detection and response catch what gets through. We invest first where risk reduction is greatest, then build the monitoring that proves controls keep working.

We collect configuration data, review Entra ID sign-in and role assignments, analyze Defender for Cloud findings and interview your teams.
Deliverables: Assessment report · Attack path summary
- 02
Prioritize by Risk
We rank issues by likelihood and impact, separating quick wins from structural changes that need planning.
Deliverables: Prioritized backlog · Quick-win list
- 03
Harden as Code
We implement fixes through Bicep, Terraform and Azure Policy so they are repeatable and do not drift back.
Deliverables: Code-based controls · Change records
- 04
Detect and Respond
We tune Sentinel and Defender detections for your environment and define who responds, how and within what timeframe.
Deliverables: Detection rules · Response playbooks
- 05
Review Continuously
Monthly reviews of secure score, new recommendations, incidents and policy compliance keep posture improving.
Deliverables: Monthly security report · Updated roadmap
Use Cases
Azure Security Use Cases
Situations where we help security and platform teams work together.
Pre-Audit Hardening
A SaaS company preparing for a SOC 2 audit closes gaps in access reviews, logging and encryption, and uses policy compliance reports as evidence.
Admin Rights Reduction
Permanent Owner and Global Administrator assignments are replaced with just-in-time PIM activation and approval workflows.
Public Endpoint Elimination
Storage accounts, SQL databases and Key Vaults move behind private endpoints, with Azure Policy preventing new public exposure.
Container Security
AKS clusters gain Defender for Containers, image scanning in the CI pipeline and network policies between namespaces.
SIEM Modernization
An organization moves from an on-premises SIEM to Microsoft Sentinel, migrating detection logic and connecting cloud and identity logs.
Secure AI Workloads
Azure OpenAI resources are deployed with private networking, managed identities and Defender for Cloud AI threat protection.

Azure Security FAQ
What does an Azure security assessment include?
We review identity configuration in Microsoft Entra ID, role assignments, Conditional Access and authentication methods; management group and policy structure; network exposure; Defender for Cloud recommendations and plan coverage; logging and monitoring; key management; and backup protection. Findings are mapped to the Microsoft cloud security benchmark and to your frameworks, ranked by risk and paired with concrete remediation steps and effort estimates.
Do we need Microsoft Sentinel, or is Defender for Cloud enough?
They do different jobs. Defender for Cloud manages posture and protects workloads with recommendations and threat alerts. Microsoft Sentinel is a SIEM and SOAR solution that collects logs from many sources, correlates events and automates response. Smaller environments may start with Defender for Cloud and Defender XDR, while organizations with compliance logging requirements or a security operations function usually add Sentinel.
What is changing with Sentinel and the Defender portal?
Microsoft is moving Sentinel management into the unified Microsoft Defender portal, bringing SIEM and XDR together in one experience. Microsoft has announced that managing Sentinel in the Azure portal will end on March 31, 2027. We plan transitions for clients that still work in the Azure portal, including updating runbooks, permissions and automation, so the change does not disrupt incident response.
How do you avoid breaking things when tightening security?
We stage changes carefully. Conditional Access policies start in report-only mode, Azure Policy assignments begin in audit mode before deny, and network changes are tested in non-production first. Every change is delivered as code with a rollback path, scheduled with application owners, and communicated in advance. This lets us improve security quickly without surprising users or causing outages.
What drives the cost of Azure security?
Costs come from our assessment and implementation effort, which depends on environment size and complexity, and from Azure consumption for services such as Defender for Cloud plans, Sentinel data ingestion and retention, Azure Firewall and DDoS Protection. Sentinel costs in particular depend on which logs you ingest and how long you keep them, so we design data collection deliberately and review it regularly.
Can you provide ongoing security operations?
We can provide ongoing posture management, detection tuning, policy maintenance and monthly security reviews as a managed service, working alongside your internal team or your existing SOC provider. We agree response times and escalation paths in advance. For round-the-clock incident response we can integrate with a dedicated managed detection and response provider of your choice.
