Last update: Aug 8, 2026

With over 25 million indexings per day, the Vallanx database is continuously updated and expanded. Our threat intelligence feeds & blacklists are individually configurable and currently cover nearly 20 data types and 30 different content filters.

The Vallanx Threat Intelligence Feed is continuously generated. It consists of all important feeds on new Indicators of Compromise (IoC) and threat-specific IoCs, which are added on a daily basis directly from research publications. This enables the best possible coverage of all threat categories, such as ransomware, phishing campaigns, malware, file hashes of packages, etc.
