Security and Performance Testing for SASE and Zero Trust

This executive brief outlines the security and performance testing strategies for SASE (Secure Access Service Edge) and Zero Trust environments. It details the three guiding principles for SASE validation, which include testing realistic application workloads, characterizing key performance indicators (KPIs), and ensuring scalability and resiliency of cloud-native infrastructures. The document also identifies challenges in SASE testing, such as validating edge cloud availability and achieving optimal performance-security trade-offs. Key testing considerations emphasize a vendor-neutral approach, selecting appropriate traffic patterns, stress testing prior to deployment, and assessing with real traffic to identify vulnerabilities. Additionally, it discusses the quantifiable business results of implementing Spirent's SASE validation solutions, which include lower costs, reduced risk of security breaches, lower customer churn rates, faster innovation, and the ability to scale services confidently. The brief serves as a comprehensive guide for organizations looking to enhance their security posture and performance in a SASE framework.
