Rankings only go so far. Look up your domain for free and see which employees, customers and suppliers have already been hit by infostealers.
Scores are Hudson Rock's editorial opinion of each vendor's infostealer intelligence, based on public information (websites, documentation and published research) as of October 12, 2026. Only infostealer-related capabilities are assessed, not a vendor's overall quality or other products. Field averages, peer matches and comparisons are calculated from those scores.
This is general information, not a recommendation to buy or avoid any product, and it may be out of date: confirm details with each vendor. Product names and logos belong to their owners and are used only to identify them. Vendors can request a correction through Hudson Rock's contact page.
