Zscaler's Stock Surges 16.75% in Two Days Despite 38.02% Decline in Trading Volume Ranking 29th

On June 2, 2025, Zscaler's trading volume reached $16.81 billion, a 38.02% decrease from the previous day, ranking 29th in the day's stock market. Zscaler (ZS) rose by 6.34%, marking two consecutive days of gains, with a total increase of 16.75% over the past two days.

Zscaler's stock price surged following the announcement of an expanded partnership with Vectra AI. This collaboration aims to enhance cloud-based threat detection tools, leveraging Vectra AI's network detection and response (NDR) capabilities to provide comprehensive visibility into SASE traffic. This integration is particularly significant as enterprises increasingly adopt SASE solutions like Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA) to secure remote and hybrid work environments. The partnership ensures that organizations can maintain advanced cybersecurity visibility without compromising the agility provided by SASE architectures.

The new integration builds on the existing partnership between Vectra AI and Zscaler, extending their technical collaboration around Zscaler Private Access. By including Zscaler Internet Access, the joint solution offers a holistic view of network traffic across both secure web gateways and private access scenarios. This allows Vectra AI's NDR platform to ingest telemetry from Zscaler, enhancing capabilities for threat hunting, lateral movement detection, and forensic analysis. The integration is timely, responding to the significant market demand from enterprises transitioning to SASE-based solutions. Security operations (SecOps) and network operations (NetOps) teams, as well as CISOs, will benefit from simplified operations and enhanced security capabilities, enabling them to enforce Zero Trust policies effectively while maintaining comprehensive visibility and control.
