 __JA4: TLS Client Fingerprinting__ is [open-source, BSD 3-Clause](https://github.com/FoxIO-LLC/ja4/blob/main/LICENSE-JA4), same as JA3. FoxIO does not have patent claims and is not planning to pursue patent coverage for JA4 TLS Client Fingerprinting. This allows any company or tool currently utilizing JA3 to immediately upgrade to JA4 without delay.
