Where Hudson Rock and CloudSEK differ on infostealer intelligence, biggest gap first.
H Hudson Rock was started by former members of IDF Unit 8200 and works on one problem only: infostealer infections. Its Cavalier platform shows what each infected computer leaked, from credentials and cookies to the malware path and antivirus in place, and splits a company's exposure into employees, users, third parties and suppliers. It is also the research team behind InfoStealers.
C CloudSEK, from Bengaluru, offers a family of external-threat products. XVigil watches the deep and dark web, Telegram and paste sites for leaked credentials, with stealer logs as one input among several.

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This is general information, not a recommendation to buy or avoid any product, and it may be out of date: confirm details with each vendor.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