DarkSail creates security products that leverage the JA4+ fingerprinting methods, JA4+ Database, and AI to safeguard networks at the application layer in real time.
JA4+ Fingerprinting
JA4+ is a suite of industry-standard network fingerprinting methods that enable the specific identification of all traffic on a network.
The telemetry that feeds these methods is collected passively, in real time, using metadata found in the messages sent between clients and
servers.

JA4+ Database
The JA4+ Database is a community-maintained repository of JA4+ fingerprints sourced from networks across the Internet.
DarkSail's products analyze both fingerprints their users create and those in the JA4+ Database to protect networks from known threats and
identify new ones.
AI
DarkSail's products utilize proprietary AI models informed by our implementations of the JA4+ methods and the JA4+ Database to minimize false positives and catch attackers, every time.
