Top Cybersecurity Head-to-Head Comparisons
Crowdstrike vs Palo Alto
Palo Alto Networks is bigger by revenue, reporting $11.48 billion for fiscal 2026 (year ended July 31, 2026) versus CrowdStrike's $4.81 billion for its fiscal 2026 (year ended January 31, 2026). Palo Alto was also more valuable, worth about $306.5 billion against CrowdStrike's roughly $269 billion as of September 25, 2026. CrowdStrike generated more free cash flow relative to its size ($1.24 billion, a 26% margin) and posted a $162.5 million GAAP net loss, while Palo Alto was GAAP-profitable with $307 million of net income after absorbing acquisition costs.
Crowdstrike vs Wiz
CrowdStrike is far larger by reported revenue: $4.81 billion for fiscal 2026 (year ended January 31, 2026) versus Wiz's roughly $1 billion-plus of annual recurring revenue reported for 2025. CrowdStrike is an independent, Nasdaq-listed company (CRWD) with a market value near $269 billion as of September 2026, while Wiz is no longer independent, Alphabet completed its $32 billion all-cash purchase of Wiz on March 11, 2026, folding it into Google Cloud. CrowdStrike's George Kurtz has been CEO since 2011; Wiz's Assaf Rappaport has been CEO since 2020 and still runs Wiz inside Google.
Fortinet vs Palo Alto
Palo Alto Networks is the bigger company by revenue: $11.48 billion in fiscal 2026 (year ended July 31, 2026) versus Fortinet's $6.80 billion in calendar FY2025. Fortinet is far more profitable in dollar terms, with $1.85 billion of net income against Palo Alto's $307 million, because Palo Alto's GAAP results absorbed integration costs from its roughly $25 billion CyberArk acquisition that closed in February 2026. Gartner's 2026 Magic Quadrant for hybrid mesh firewalls ranked Fortinet above Palo Alto Networks as the top-placed leader, citing Fortinet's SD-WAN and AI automation strength, while crediting Palo Alto for quantum-safe and AI-runtime security features.
Abnormal Security vs Crowdstrike
Abnormal Security is a specialized, AI-native platform that protects cloud email (like Microsoft 365) from advanced phishing and social engineering attacks. CrowdStrike is a large, comprehensive security platform that primarily protects endpoints (laptops and servers) from malware and ransomware execution.
Cloudflare vs Palo Alto
Palo Alto Networks is the world's largest cybersecurity company, historically famous for physical corporate firewalls but actively transitioning to cloud security. Cloudflare is a large cloud-native network that protects websites from DDoS attacks and provides 'Zero Trust' remote access without requiring physical hardware.
Cloudflare vs Tailscale
Cloudflare (Zero Trust) is a large, enterprise-grade cloud security platform that routes and filters corporate traffic through its global data centers. Tailscale is a brilliant, lightweight mesh VPN tool that instantly connects devices directly to each other using the WireGuard protocol.

Editorial Methodology
We use company filings, annual reports, company statements and press reports, with primary sources preferred where available. Each financial row shows its recorded source. Full-year figures are separated from annualized run-rates, partial periods and forecasts; unaudited figures carry a label. Source detail varies by company, so check the linked material when the reporting basis matters.
Public companies may provide filings and annual reports. Private-company figures may come from statements or press coverage. A missing figure stays missing, and a source link should identify where its number came from.
We organize company records and review claims for strategic context, source quality and clarity. Pages show a review date where one is recorded.
Technical checks flag inconsistent figures and missing links. Editorial review of the underlying source remains necessary for claims those checks cannot verify.
