Who buys and manages Cloudflare inside a company?
Cloudflare is usually owned by Connectivity Cloud: Network, Security & Developer Platform. Decision-makers include CISO, CTO and VP of Infrastructure; Security Architect and Network Architect shape the choice, and Network Engineers and Security Engineers use it day to day. Our Cloudflare list can include any of these roles.
Which Cloudflare products or editions can I target?
You can target accounts by the Cloudflare products they run, including Cloudflare Application Services (CDN, WAF), Cloudflare Zero Trust (SASE), Cloudflare Workers & Developer Platform, Cloudflare Magic Transit and Cloudflare Workers AI. Tell us which edition or module matters and we filter the list to those accounts.
What other software do Cloudflare customers use?
Cloudflare customers commonly also run Okta, AWS, CrowdStrike, Terraform and Datadog. We can filter any list by this kind of stack overlap.
What are the main alternatives to Cloudflare?
The main alternatives to Cloudflare are Akamai, Zscaler and Fastly. We also keep verified user lists for Akamai, Zscaler and Fastly, which is useful for competitive displacement campaigns.
When are Cloudflare customers most likely to buy?
Buying triggers we track for Cloudflare accounts include VPN replacement, DDoS incident, SASE consolidation and workers adoption. A common pain point is VPN replacement: Legacy VPNs are risky.

Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Cloudflare criteria—including target job titles, company size, and region—delivered within one business day with no obligation.
How does Data InfoMetrix guarantee email deliverability for Cloudflare contacts?

Sourcing and compliance. Business contacts come from public company sources, professional directories and opt-in publishing partners, then go through SMTP verification and human review. Lists are for B2B outreach: include an unsubscribe link and honour opt-outs (CAN-SPAM), and have a lawful basis such as legitimate interest when you email people in the EU or UK (GDPR).
