How much of the product is actually about infostealers: a dedicated stealer-log dataset scores high, a credential feature inside a wider suite scores lower.

What is infostealer intelligence?

Machine-Level Infection Context

15%

Whether you can see the infected computer behind each credential: malware family, infection date, OS, IP, antivirus, file path and everything else taken from that machine.

What is stealer logs?

Exposure Segmentation

12%

Whether you can see who is affected (staff, customers or suppliers) and which websites the stolen logins belong to, so every team can act on its own slice.

What is third-party risk?

Session Cookie & Token Coverage

10%

Coverage of stolen session cookies and tokens, the data attackers use to skip MFA and take over accounts.

What is session hijacking?

Collection Freshness

10%

How fast newly stolen data is collected from criminal sources and becomes searchable.

What is cybercrime intelligence?

Infostealer Research & Attribution

10%

Original public research into infostealer campaigns and the breaches they lead to.

What is infostealer malware?

Whether you can test the data for free, through public lookups, a free API key or a free account.

10%

How well the data plugs into other tools: APIs, SIEM and SOAR, and identity providers.

Questions & answers

Who publishes this index?

The Infostealer Index is produced by Hudson Rock, the research team behind InfoStealers, and Hudson Rock is one of the vendors it ranks. The scores are Hudson Rock's editorial assessment of public information about each product. We show the same ranks and scores as the original on hudsonrock.com, with our own profiles and analysis.

What does the overall score measure?

Only infostealer intelligence: how well a product helps you find and act on credentials, cookies and machine data stolen by infostealer malware. Each vendor gets 0–10 on nine criteria, and the weighted total is scaled to 100. It does not rate a vendor's wider security products.

Which vendors score highest?

The top four are Hudson Rock (96.2), Flare (82.8), SpyCloud (81.3) and Breachsense (70.4). The median vendor scores 48.5.

What is the difference between a specialist and a CTI platform?

Specialists (9 in the index) build their product around stolen-credential and stealer-log data. Broad CTI platforms include stealer data as one feed among dark web, brand and attack-surface monitoring. Lookup services are search tools for querying leak data on demand.

Can a vendor ask for a correction?

Yes. Scores reflect public information as of October 12, 2026. Vendors can request a review through Hudson Rock's contact page.

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.
