VALHALLA boosts your detection capabilities with the power of thousands of hand-crafted high-quality YARA and Sigma rules. Our team curates more than 20,000 quality tested YARA rules in 8 different categories: APT, Hack Tools, Malware, Web Shells, Exploits, Threat Hunting, Anomalies and Third Party. The first five of them can subscribed, the other three are only used in a compiled and encrypted form in our scanner THOR. Valhalla’s database grows by around 1500 YARA and 250 Sigma rules every year. A subscription includes the curation of old rules. We change and improve between 300 and 500 old rules every year. With access to Valhalla, you can supercharge your detection by adding most of our highly successful THOR scanners’ signatures to your own scan engines. All rules are performance optimised and quality tested against Terabytes of goodware and other data.
