Migration to Cloud/SaaS, work-from-anywhere (WFA) adoption, and IoT proliferation have reshaped enterprise networks, prompting a stricter yet dynamic resource management approach. Zero trust network access (ZTNA), built on 'never trust, always verify,' employs identity and context awareness to establish virtual perimeters, granting access solely to authorized resources. ZTNA ensures this through continuous adaptive trust, analyzing real-time session metrics, user privileges, and usage thresholds.
This report explores how traffic visibility impacts ZTNA, highlighting poor monitoring mechanisms, increased encrypted traffic, and limited application awareness. Drawing from a survey of 55 top ZTNA vendors, it details growing data complexities, emphasizing the need for comprehensive inventories and granular data points on resources, devices, and users. Additionally, it evaluates how DPI-driven traffic analytics bolster ZTNA solutions, aligning with zero-trust principles like microsegmentation, least privilege access, single sign-on, or single DLP policy, while also assessing DPI adoption trends and its contribution to next-gen ZTNA offerings.
