CRWD vs ZS: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: ZS is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CRWD and ZS share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CRWD and ZS exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

CrowdStrike is a leading cloud-native cybersecurity company best known for endpoint protection: software that secures laptops, servers, cloud workloads, and other devices against malware, ransomware, and intrusions. Its Falcon platform uses a single lightweight agent and a cloud-delivered model that collects vast amounts of threat telemetry, applies AI and machine learning to detect attacks, and lets customers add modules across many security categories. Beyond endpoint, CrowdStrike has expanded into cloud security, identity protection, threat intelligence, security operations and log management (Next-Gen SIEM after acquiring Humio/LogScale), exposure management, and managed detection and response. It makes money primarily through recurring subscriptions, with customers often adopting more Falcon modules over time, driving strong net revenue retention. CrowdStrike is one of the fastest-growing large cybersecurity vendors and a platform-consolidation play, helping enterprises replace multiple point tools. It is headquartered in Austin, Texas, and serves enterprises and governments worldwide.

Zscaler is a cloud-native cybersecurity company built around the zero trust security model. Instead of routing traffic through a traditional corporate network perimeter, Zscaler operates a globally distributed cloud platform that sits between users and the applications they access, inspecting traffic and enforcing security policy in real time. Its two flagship products are Zscaler Internet Access (ZIA), which secures connections to the public internet and SaaS apps, and Zscaler Private Access (ZPA), which connects users directly to private applications without exposing the corporate network.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CRWD drivers: Platform consolidation and module land-and-expand; AI-driven detection and data advantage.
• ZS drivers: Zero trust replacing legacy perimeter; Platform expansion and upsell.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: CrowdStrike trades at a very high valuation that prices in sustained rapid growth, leaving little room for disappointment: after doubling in 2026 it trades at about 43x trailing sales and about 141x forward earnings, and the stock pulled back from record highs in mid-October as software stocks cooled. For ZS, zscaler trades at a high revenue multiple (about 10x trailing sales and 36x forward earnings as of October 2026), so any deceleration in growth or billings can compress the stock sharply; the drop from about $337 to about $115 within the past 52 weeks shows how fast that can happen, and consensus expects revenue growth to slow from about 25% to about 17% in fiscal 2027.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CRWD if you believe its drivers more; ZS if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CRWD and ZS guides.

CRWD. CrowdStrike trades at one of the richest valuations in large-cap software, about 43x trailing revenue in mid-October 2026 versus roughly 28x a year earlier, after the stock doubled on re-accelerating growth and a raised ARR outlook. The premium embeds expectations of years of sustained expansion toward the $10 billion ARR goal. Analysts rate it a buy with an average target near $246, only modestly above the current price, so the valuation remains the key debate.

ZS. As of October 16, 2026, Zscaler traded near $204 at about 10x trailing sales and 36x forward earnings, a premium multiple typical of high-growth cloud security names but well below where it stood a year earlier, after a 32% one-year decline. The multiple reflects durable subscription revenue and free cash flow above $1 billion despite thin GAAP profitability. The valuation is sensitive to billings and net retention trends, and with consensus pointing to slower fiscal 2027 growth (about 17%), a further slowdown or rising competitive pressure would compress the multiple quickly; the 44 covering analysts have a mean target near $234.

Headline figures (approximate, October 2026): CRWD shows revenue (ttm) ~$5.4 billion; FQ2 2027 ~$1.47 billion (up ~26% YoY), annual recurring revenue (arr) ~$5.84 billion; record net new ARR ~$333 million (up ~51% YoY), eps FQ2 2027 adjusted $0.31 vs ~$0.29 consensus; GAAP near breakeven (TTM net income ~$45 million), free cash flow ~$2 billion (TTM); ZS shows revenue (fy2026, ttm) ~$3.35 billion, revenue growth ~25% year over year (fiscal Q4 2026), operating margin (gaap) ~-1%, near breakeven, non-gaap eps (fiscal q4 2026) ~$1.19 vs ~$1.09 est..

CRWD and ZS are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CRWD and ZS exposure against your real portfolio. It is not an investment adviser.
