Free/Open source TAXII Servers and intel feeds

[KonstantinToman]

Hello all,

I have spent some time to look for free TAXII Servers and intel feeds. My point is to create some custom feeds and enrich the threat Intelligence data. So far I have found only three available servers/services that can be integrated with Netwitness for free - Hailataxii, OTX(AlenVault) and Limo(Anomali).

Are there any other free services that I have missed?

What is the most preferred channel in your opinion?
