Our current thesis
Updated Oct 12, 2026
The thesis
- Leader in Zero Trust SASE architecture positioned to capture enterprise AI security expansion.
- Backlog of $7.37B in RPO and 98% subscription revenue ensure robust top-line visibility.
- Strong liquidity cushion with $3.47B in cash and durable 23% free cash flow margin.
Risks
- Top-line revenue growth guided to decelerate sharply to ~17% in FY27, trailing PANW.
- Spike in AI data center CapEx constrains near-term free cash flow margin expansion.
- Leadership turnover with new CRO Ross Tackett poses near-term go-to-market execution risks.
What we're watching
- Q1 FY27 earnings on November 24, 2026 for ARR trajectory against 17% guide.
- Net new ARR contributions from new offerings including Security for AI and Z-Flex.
- Consolidation support near the $215-$220 level following the post-Investor Day rally.
Latest
ZS has surged 42% over the past month to $233.73 (41.6x forward P/E), catching up to analyst targets following an Investor Day highlighting an $8B+ ARR goal by FY31. While Q4 FY26 delivered 24.9% revenue growth and an EPS beat of $1.19, FY27 top-line guidance reflects deceleration to ~17% alongside elevated AI infrastructure CapEx. Strong balance sheet liquidity of $3.47B cash and $779M trailing FCF cushions downside, but valuation is fully priced following the recent run.

Who it does business with
- Palo Alto Networks competes with Zscaler — SASE & zero trust. Prisma Access vs the Zero Trust Exchange for the corporate network that no longer has a perimeter.
- Zscaler competes with Cloudflare — Zero-trust edge. Two cloud edges selling the same replacement for the VPN and firewall: Zscaler from security, Cloudflare from the network up.
- Zscaler partners with CrowdStrike — Zero-trust integration. A long-running alliance: Falcon’s device-health signals feed Zscaler’s access decisions, and the two co-sell into the same zero-trust deals.
