Thank you, @rgonzalez

Uhm…,  
So “3coresec.rules”, “ciarmy.rules” and other third-party rules are the same as “ET Open”, are they under BSD license?

I found this post. I am wondering because in this case it is GPL 2.0.

> Hi. To me it’s not really clear if the compromised-ips.txt file below is in the Open-Package, or if it’s Pro. [https://rules.emergingthreats.net/blockrules/compromised-ips.txt](https://rules.emergingthreats.net/blockrules/compromised-ips.txt) Is there any overview which list belongs to which ? What licensing model does it use ? Are they also all free to be used by companies ? Not for reselling, just to be used on a GW etc… KInd regards, Franzl
