Company Overview
Zscaler operates the world’s largest inline security cloud, processing over 400 billion transactions daily across its Zero Trust Exchange platform. The company has positioned itself at the centre of a fundamental shift in enterprise security architecture: the replacement of legacy perimeter-based security (firewalls, VPNs) with cloud-native, identity-centric zero trust models.
The product suite spans four pillars: Zscaler Internet Access (secure internet traffic), Zscaler Private Access (replace VPNs), Zscaler Digital Experience (performance monitoring), and Zscaler Data Protection. This breadth allows the company to expand within existing accounts, driving net revenue retention rates consistently above 120%.
Zscaler’s competitive moat rests on its cloud architecture. Unlike competitors bolting cloud features onto legacy appliances, Zscaler was built cloud-native from the start. Its 150+ global data centres process traffic inline, providing security without latency penalties. The platform effect deepens as more traffic flows through the exchange, improving threat detection through scale.
Framework Read
Zscaler’s chart structure shows a recovery markup following a significant correction from its 2024 highs. The stock has formed a constructive base and is now advancing with improving momentum. Buyers are defending higher lows, and the trend structure has shifted from a series of lower highs to a confirmed uptrend.
The most notable feature is the volume expansion on the recent breakout above the $120 level, which had served as resistance for several months. Institutional participation appears to be increasing, with block trade activity picking up on advancing sessions.
Key technical observations:
- Clean breakout above $120 resistance on above-average volume
- Price reclaiming the 200-day moving average for the first time in months
- MACD histogram turning positive on the weekly timeframe
- Relative underperformance versus the cybersecurity sector is narrowing
Ethical Screening
Zscaler is a cybersecurity company providing cloud-based protection services. The business model is fundamentally aligned with positive outcomes: protecting organisations and their users from cyber threats. No revenue from prohibited sectors.
The company serves government and defence clients, which some ethical screens may flag, but the services provided are defensive in nature (protecting networks) rather than offensive. Debt levels are manageable, and the company generates positive free cash flow. Ethical screen: PASS. Eligible for ethically screened portfolios.
Valuation Context
At $131, Zscaler trades at approximately 8x forward revenue and 40x forward free cash flow. The valuation has compressed meaningfully from its 2021 peak multiples of 50x+ revenue, bringing it closer to the cybersecurity sector median.
The bull case is straightforward: every enterprise on the planet needs to adopt zero trust security, and Zscaler is the market leader. The total addressable market exceeds $96B, and Zscaler’s current revenue run rate captures less than 3% of it. Large enterprise deals are accelerating, with the $1M+ ARR customer cohort growing faster than the overall base.
The bear case focuses on competition from CrowdStrike, Palo Alto Networks, and cloud providers building native security features. Growth deceleration is also a concern, as Zscaler’s revenue growth has moderated from 60%+ to the high 20s. At current multiples, the stock needs to sustain growth to justify the valuation.
What to Watch
- Billings growth: The leading indicator for future revenue. Acceleration above 25% would reignite growth sentiment.
- Large deal momentum: $1M+ ARR customers growing faster than 30% signals enterprise adoption is deepening.
- Free cash flow margins: Expansion towards 30%+ would demonstrate operating leverage and support the valuation.
- Competitive wins/losses: Monitor Gartner Magic Quadrant positioning and head-to-head win rates against Palo Alto.
- Federal spending: US government zero trust mandates create a guaranteed demand floor, but budget cycles can create lumpiness.
