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This is general information, not a recommendation to buy or avoid any product, and it may be out of date: confirm details with each vendor.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.
