Zscaler is trading 10.1% up at $192.61 as enterprise-software rotation continues and investors reassess AI-safety risks.

  • The move follows a 16.52% gain on September 14, extending a sharp two-session rebound.
  • No new company-specific catalyst clearly explains the September 15 move; Zscaler’s September 15 service incident was reported largely resolved, not as a bullish announcement.
  • Recent AI-security messaging and strong quarterly results remain supportive background, but are not fresh catalysts.
