Strengthening Your Multi-Cloud Security: A Guide to Microsoft Defender’s Cloud Security Posture Management
In today’s rapidly evolving cloud landscape, maintaining a strong security posture across multiple cloud environments is crucial. Microsoft Defender for Cloud offers a robust Cloud Security Posture Management (CSPM) solution designed to help organizations safeguard their multi-cloud environments. This solution comes in two flavors: the free Foundational CSPM and the more advanced Defender CSPM, each providing a suite of features tailored to meet different security needs.
Understanding Cloud Security Posture Management (CSPM)
Microsoft Defender for Cloud offers foundational and advanced cloud security posture management solutions to protect across your multicloud and hybrid environments. Foundational CSPM (for free) provides continuous assessments, security recommendations, Secure Score, and the Microsoft cloud security benchmark across Azure, Amazon Web Services(AWS), and Google Cloud.
Microsoft Defender CSPM provides advanced security posture capabilities including agentless vulnerability scanning, attack path analysis, integrated data-aware security posture, code to cloud contextualization, and an intelligent cloud security graph.
CSPM solutions identify and remediate risks across various cloud services, ensuring compliance with security policies and regulatory standards. Microsoft Defender CSPM integrates with Azure, AWS, Google Cloud Platform, and other cloud environments to provide a unified security framework, designed to continuously monitor and improve the security posture of cloud environments.
Key Features of Microsoft Defender CSPM
- Unified Security Management
- Automated Threat Detection and Response
- Compliance Management
- Risk Assessment and Remediation
- Integration with Existing Tools
Analyzing Blast Radius with Cloud Security Graph in Microsoft Defender CSPM
The Cloud Security Graph in Microsoft Defender CSPM visualizes the relationships between cloud resources, helping to identify and mitigate the potential blast radius of security incidents.
By mapping these dependencies, it enables proactive isolation and protection of critical assets to reduce the overall impact of breaches.
Attack Path Analysis in Microsoft Defender CSPM
Attack Path Analysis in Microsoft Defender CSPM identifies potential routes an attacker could exploit to move laterally within your cloud environment.
By visualizing these paths, it helps in proactively strengthening security controls to prevent unauthorized access and limit the spread of attacks.
Cloud Security Explorer in Microsoft Defender CSPM
Cloud Security Explorer in Microsoft Defender CSPM provides an interactive, visual tool to navigate and investigate your cloud environment.
It allows security teams to explore resource configurations, detect vulnerabilities, and understand security postures using pre-built query templates, enabling proactive identification and remediation of potential risks.
Driving Security Improvement with Governance in Microsoft Defender CSPM
Microsoft Defender CSPM empowers organizations to enhance their security through robust governance features. Security teams can set accountability for recommendations, track progress, and drive owners to action using built-in notification capabilities.
Additionally, workload owners can focus on specific recommendations that require their attention, ensuring targeted and efficient remediation efforts.
Recommendations in Microsoft Defender CSPM
Microsoft Defender CSPM offers tailored recommendations aligned with various regulatory compliance standards, including NIST SP 800–53 Rev 5, AWS-NIST SP 800–53 Rev 5, GCP-NIST SP 800–53 Rev 5, and more. By assessing your resources, it provides specific remediation steps and flags them as red or green based on their compliance status, ensuring your cloud environment meets required security standards.
Following these recommendations not only improves security across all three cloud environments but also helps maintain regulatory compliance and strengthens overall cloud security posture.

Security Posture Feature in Microsoft Defender CSPM
The Security Posture feature in Microsoft Defender CSPM provides a comprehensive overview of your organization’s security across all three cloud environments — Azure, AWS, and GCP — once onboarded.
It showcases the secure score and environment risk, categorizing recommendations by severity (Critical, High, Medium, Low, Not Evaluated). Additionally, it highlights the environments where CSPM is onboarded, identifies unhealthy resources, visualizes attack paths, and offers actionable recommendations to strengthen your security posture effectively.
Compliance Assessment and Management in Microsoft Defender CSPM
Microsoft Defender CSPM offers robust capabilities for assessing and managing compliance across your cloud environments:
- Assess and Manage Compliance Status: Utilize Defender CSPM to assess and manage your organization’s compliance status with various regulatory standards and industry benchmarks. It provides comprehensive visibility into compliance posture and offers remediation guidance to address any gaps.
- Cloud Security Benchmark: Leverage the Cloud Security Benchmark provided by Defender CSPM to measure your organization’s adherence to industry best practices and security standards. This benchmark helps in evaluating security posture across multiple dimensions and aligning with leading security frameworks.
- Custom Recommendations and Standards: Customize compliance assessments and standards to align with your organization’s specific requirements and regulatory obligations. Defender CSPM allows you to create and implement custom recommendations and standards tailored to your unique cloud environment and compliance needs.
Data-aware security posture
Microsoft Defender CSPM empowers organizations to enhance their data-aware security posture through a streamlined process:
- Onboard: Seamlessly onboard your cloud environments onto Defender CSPM to initiate comprehensive security monitoring and management.
- Auto-discover: Automatically discover and classify sensitive data within your cloud infrastructure using Defender CSPM’s advanced data discovery capabilities. Gain insights into data flows and storage locations to understand potential risks.
- Uncover Risks: Identify and assess data-related risks across your cloud environments. Defender CSPM provides proactive risk assessment tools to uncover vulnerabilities, misconfigurations, and potential threats to sensitive data.
- Remediate Risks: Take swift action to remediate identified risks and strengthen your data security posture. Leveraging Defender CSPM’s remediation capabilities, implement security controls, apply access restrictions, and enforce encryption to mitigate risks effectively.
Defender CSPM pricing guidance
Pricing is dependent on cloud size, with billing based only on only Server, Storage account, and Database counts.
Additionally, it includes DevOps security capabilities to empower security teams to manage DevOps security across multi-pipeline environments.
Cloud workload protection plans
Microsoft Defender for Cloud provides cloud workload protection to help organisations quickly prevent, detect, and respond to modern threats across multi-cloud and hybrid environments. Get advanced threat protection capabilities to secure critical workloads across virtual machines (VMs), containers, databases, storage, app services, APIs, and more.
Conclusion
Microsoft Defender CSPM provides powerful tools to protect your cloud security across multi-cloud environments.
