Develop a comprehensive multicloud security strategy

Watch the interview with guest Andras Cser, Vice President and Principal Analyst, Forrester, on developing a cloud security strategy.

Why cloud security?

In the era of cloud transformation, customers face an increasingly complex environment and need the right strategy to safeguard their infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) services.

Strengthen your cloud security posture

Optimize the configuration of cloud services with extensive assessment tools.

Defend against evolving threats

Protect cloud workloads and apps from threats with the help of leading security research and threat intelligence.

Control access to critical cloud apps and resources

Enforce real-time access controls using built-in risk assessments and contextual information.

Secure every step of the development lifecycle

Safeguard the entire app development, deployment, and operations lifecycle directly within the standard developer workflow.

What is cloud security?

Strengthen your cloud security posture

  • Know what’s going on

    Continuously assess the security state of your cloud resources across virtual machines, networks, apps, and data services in Azure, AWS, and GCP environments. Monitor server workloads in on-premises datacenters and quickly get insights with visualization of the entire security state.

  • Get guidance and recommendations

    Improve your security posture and prevent common misconfigurations. Secure Score is at the core of the security posture management capabilities in Defender for Cloud. Get insights into your current state along with recommended actions to prioritize the steps you can take to improve your security posture.

  • Have more control

    Manage and enforce your cloud security policies and make sure your virtual machines and PaaS services are compliant. Set your policies to run on management groups, across subscriptions, and even for a whole tenant.

  • Streamline cloud security posture management

    Easily deploy and configure Microsoft Defender for Cloud across large-scale environments using policies and automation. Use AI and automation to quickly identify threats, improve threat investigation, and help automate remediation. Streamline threat mitigation by connecting to existing tools such as Microsoft Sentinel, the SIEM solution from Microsoft, or by integrating partner security solutions.

Protect your multicloud and hybrid workloads

  • Protect Azure and AWS services

    Safeguard your virtual machines, data, cloud-native services, and IoT against common threats such as brute-force password attacks, SQL injection attacks, and threats against containers.

  • Protect hybrid cloud resources

    Understand the security state of your hybrid cloud workloads in a single console and help protect your Linux and Windows servers from threats.

  • Take advantage of comprehensive threat intelligence

    Streamline threat investigation with AI and advanced automation. Strengthen protection for users, devices, and apps using the integration between Microsoft Defender for Cloud and Microsoft 365 Defender. Bring all your security analytics together into a unified view with Microsoft Sentinel.

Control access to critical apps and resources

  • Discover and control cloud apps

    Get deep visibility into shadow IT and control access to cloud apps and services. Assess the risk level and business readiness of more than 26,000 apps and start managing them against your security and compliance requirements.

  • Protect the access and use of sensitive data

    Classify and label business-critical data and implement adaptive access controls (based on contextual factors such as user, device, location, etc.) to prevent improper data use and sharing during user sessions

  • Manage entitlements and access permissions for your cloud resources

    Take advantage of cloud infrastructure entitlement management (CIEM) capabilities provided by CloudKnox to manage privileged access and permissions – across hybrid and multicloud environments. Control access to your cloud infrastructure through continuous monitoring, assessing, and right-sizing of unused and excessive permissions.

  • Protect resources and apps with cloud-native network security

    Safeguard your Azure virtual network against threats and protect web apps and workloads. Use our cloud-native firewall to filter traffic, and DDoS protection for always-on defense against attacks.

Develop and operate secure apps

  • Build secure apps faster

    Get all the tools you need to secure your app with GitHub and Azure—all fully integrated into the platform, whether you use Microsoft or open-source tools. Start with threat modeling to identify potential threats and perform static and dynamic code analysis to find vulnerabilities.

  • Get dependency updates automatically

    Use Dependabot to scan dependencies from other libraries or components, including open source, for vulnerabilities and the latest updates. Ensure your secrets, such as connection strings and keys, are stored securely in repositories backed by hardware security modules, not embedded in your code.

  • Protect the stack, top to bottom

    Enable multifactor authentication to protect identity and use a firewall to protect the network. Protect data with encryption at rest and in transit. Strengthen data encryption through the confidential computing family of virtual machines in Azure.

  • Use our best practices and tools

    Access current Microsoft Defender for Cloud best practices for securing apps so you know exactly what steps we recommend and implement with the same toolkit we use to secure our own apps.

What customers are saying

Monitor and control apps with Microsoft Defender for Cloud Apps

“Previously, I had to use several tools and portals to do what I now do on one screen with Microsoft Defender for Cloud Apps (formerly Microsoft Cloud App Security). It’s a huge improvement in my workflow because it takes less time to monitor suspicious events. I also have more confidence that I’m seeing what I need to see. With multiple dashboards, it was harder to track everything we need to watch.”
