Qualys, Inc.: what insiders have been doing
Every trade that managers of Qualys, Inc. disclose to SEC (Form 4) is tracked on this page. The company sits in the Technology sector and is based in Foster City, United States. It was founded in 1999. The last twelve months, up to 18 October 2026, brought 103 filings signed by 11 insiders.
There is no open-market purchase to report; the filings show 72 sales worth €4.6M by 5 insiders. The totals do not cover 1 filing with an undisclosed amount. The largest single trade was a sale of €294k by Thakar Sumedh S, published on 13 November 2025.
Typically, a trade is published a median of 1 day after it takes place. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Compared with its exchange (5,810 companies, median 19 filings), a count of 103 filings is above the norm. The full history, which starts in 2016, counts 1 purchase against 164 sales. The 10-K for the year ended 31 December 2025 shows 669.1 m USD of revenue and 198.3 m USD of net income.
In the same sector, recent insider purchases at Core Scientific, Inc./tx and Gitlab Inc. also feature in our signals. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
