This is an early release of the FreeTAXII Server (version 0.3.1). This version of the FreeTAXII Server is artificially limited to only support STIX 2.1 Indicators and open authentication (meaning authentication has been artificially disabled).
I am including both MacOSX and Linux x64 prebuilt binaries. In order to run the FreeTAXII Server you must generate TLS certificates as outlined in the README file in the etc/tls/ directory.
