Fortinet, Inc.
A maker of cybersecurity hardware and software, Fortinet protects computer networks for businesses, governments, and service providers worldwide, with its flagship FortiGate firewall at the center of a broad product family. Founded in 2000 by brothers Ken and Michael Xie, the name blends "fortified" and "network" — and before settling on it, the founders briefly tried Appligation and ApSecure. The "Forti-" prefix now runs through nearly every product, from FortiManager to FortiClient.

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 all recorded history: -17.35M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
