Commvault Systems Inc
A maker of cyber-resiliency software, Commvault helps businesses back up, protect, and recover their data through its Commvault Cloud platform, which includes tools for ransomware recovery and isolated "cleanroom" testing. Its roots trace to 1988, when it began as a data-management group inside Bell Labs before spinning off as an independent company in 1996. The name is a portmanteau of "communication" and "vault," reflecting its telecom heritage and its job of safely storing data.

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: -15.89M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
