CrowdStrike makes money mainly from subscriptions to its Falcon platform, which accounts for roughly 95% of revenue; the rest comes from professional services such as incident response. Customers deploy one sensor and pay per protected endpoint, workload, or identity, then add modules (EDR/XDR, identity protection, cloud security, Next-Gen SIEM, exposure management, Charlotte AI) without installing new software. Falcon Flex lets customers pre-commit spend and switch modules on as needed. Ending ARR from Flex accounts passed $2.29 billion in July 2026, up 101% year over year. Sales run through a direct field team, channel partners, MSSPs, and cloud marketplaces such as AWS Marketplace.
