Azure network security

Protect your applications and cloud workloads from network-based cyberattacks with network security services.

Take a zero-trust approach to help secure your workloads

Whether you're moving workloads or modernizing apps on Azure, using cloud-native controls and services improves business agility and saves costs on security infrastructure. Improve cloud network security using a Zero Trust approach to perform network segmentation and apply intelligent threat protection and traffic encryption.

Increase development speed by integrating network security and development with DevSecOps. Implement infrastructure as code and incorporate security controls directly into application development workflows to accelerate development and time to market.

Improve security for your Azure workloads with automated network security management and upgrades, and increase visibility into your environment. Azure network security reduces the likelihood of a security breach, as well as the associated costs of a breach.

Help IT teams deliver network-related work more efficiently and with faster deployments. The Total Economic ImpactTM of Microsoft Azure Network Security, a commissioned study conducted by Forrester Consulting, found that Azure network security reduces firewall management by 80 percent, security policy management by 15 percent, and security audit process by 96 percent.

Save on costs for the maintenance of on-premises security tools and time-consuming vendor management. The Total Economic ImpactTM of Microsoft Azure Network Security, a commissioned study conducted by Forrester Consulting, found that interviewees saved costs to maintain decommissioned on-premises infrastructure and security tools as well as time-related costs for vendor management. They also reduced their total cost of ownership of on-premises security tools by 25 percent while protecting 20 percent of their organization's total computing with Azure network security.

Frequently asked questions

  • Cloud-native is all about speed, scale and agility. When you choose a cloud-native network security service, you can deploy a service much quicker, with auto-scaling capability and at a lower cost. In addition, a cloud-native service provides better integration with other Azure services that you are using, thus giving you a lot more agility to move workloads to the cloud.
  • Azure Firewall and Azure DDoS Protection are two services you should start with if you are moving workloads that has external IP addresses. This will ensure that you have network traffic filtering and protection from denial of service attacks that could cause service disruption to your workload.
  • Azure Web Application Firewall and Azure DDoS Protection are two services that can help protect your web applications from malicious attacks, bots, and common web vulnerabilities.
  • Try Azure Bastion, a fully managed service that provides more secure and seamless Remote Desktop Protocol (RDP) and Secure Shell Protocol (SSH) access to virtual machines (VMs) without any exposure through public IP addresses.
  • Visit the Zero Trust website to find everything you need to know about proactive security with Zero Trust, including the Zero Trust Maturity Model and Zero Trust Adoption Report.
