The 2015 WAN Challenge

Traditional WAN architecture had a spoke and hub design. Enterprises architected a connection to the nearest data center using MPLS or some other leased-line style connection. Using symmetrical optimization technology at both the branch and data center squeezed out more bandwidth and reduced response time. All Internet-bound traffic passed through the data center's security, creating a strong perimeter defense for the enterprise. The data center also has web screening to ensured employees didn’t go someplace inappropriate or create a security risk. This WAN design for branch offices worked for decades, but it doesn’t any more.

Threat detection and response in cloud environments

whitePaper | December 20, 2022

Cloud environments change fundamental assumptions in how to perform threat detection and response. The highly dynamic inventory of cloud workloads means systems come and go in seconds. When system configuration errors are introduced during a build, they can be exacerbated and amplified when automation replicates the errors across many workloads. Shared responsibility with the cloud service provider (CSP) creates potential threat detection gaps in the attack lifecycle.
