Scale security on the fly in Microsoft Azure Cloud with Cisco Secure Firewall

The release of Microsoft Azure Gateway Load Balancer is great news for customers, empowering them to simply and easily add Cisco Secure Firewall capabilities to their Azure cloud infrastructure. By combining Azure Gateway Load Balancer with Cisco Secure Firewall, organizations can quickly scale their firewall presence across their Azure cloud environment, providing protection for infrastructure and applications exactly where and when they need it.

With applications and resources hyper-distributed across hybrid-multicloud environments, organizations require agile security to protect their environment at each control point. This integration empowers organizations to dynamically insert Cisco’s security controls and threat defense capabilities in their Azure environment, removing the clunkiness of provisioning and deploying firewalls, as well as the need to rearchitect the network. Organizations can now enjoy highly available threat defense on the fly, protecting their infrastructure and applications from known and unknown threats.

Securing cloud infrastructure while reducing complexity

Combining Secure Firewall with Azure Gateway Load Balancer offers a significant reduction in operational complexity when securing cloud infrastructure. Azure Gateway Load Balancer provides bump-in-the-wire functionality ensuring Internet traffic to and from an Azure VM, such as an application server, is inspected by Secure Firewall without requiring any routing changes. It also offers a single entry and exit point at the firewall and allows organizations to maintain visibility of the source IP address. Complementing these features, organizations can take advantage of our new Cloud-delivered Firewall Management Center. It enables organizations to manage their firewall presence 100% through the cloud with the same look and feel as they’ve grown accustomed to with Firewall Management Center. With Cloud-delivered Firewall Management Center, organizations will achieve faster time-to-value with simplified firewall deployment and management.
