Azure network security
Protect your applications and cloud workloads from network-based cyberattacks with network security services
Take a ZeroTrust approach to help secure your workloads
Whether you're moving workloads or modernizing apps on Azure, using cloud-native controls and network security 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 management 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.
