I noticed that Cloudflare WAF users span an incredibly diverse range of activities, but they share a common thread: most are building or operating digital platforms that handle sensitive data or customer interactions. These aren't just tech companies. I found consulting firms managing client information, educational platforms connecting students with resources, healthcare facilities handling patient data, financial services companies, and businesses running e-commerce or SaaS platforms. What unites them is that their core operations depend on web-based systems that require protection.

The maturity levels vary widely. I found early-stage startups with seed funding under $5M, mid-stage companies raising Series A or B rounds, and established enterprises with hundreds or thousands of employees. However, a significant portion fall into the 11-200 employee range, suggesting growing companies that have achieved product-market fit and are scaling operations. Many show no recent funding, indicating they may be profitable, bootstrapped, or privately held mature businesses.
