Cloudflare, Inc.
A company that keeps websites fast, safe, and online by acting as a "firewall in the cloud" — routing traffic through its global network to fend off cyberattacks and speed up loading for millions of sites. Co-founders Matthew Prince, Michelle Zatlyn, and Lee Holloway launched it in 2009, building on their earlier Project Honey Pot, which tracked how spammers harvested email addresses. The name came from a friend's suggestion for a "firewall in the cloud," fitting a service that shields and accelerates internet traffic.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -17.13M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
