The IP has no reverse name configured:

    > nslookup 147.67.37.17
    ** server can't find 17.37.67.147.in-addr.arpa: SERVFAIL

So I'm not sure where the host name from the firewall software is coming from.

I tried and got a certificate that looks like it is from the European Commission

    > curl -v https://147.67.37.17
    ...
    * Server certificate:
    *  subject: C=BE; ST=Brussels-Capital Region; L=Brussels; O=European Commission; CN=*.ec.europa.eu
    ...

It looks like this is a server from the EC and I consider it unlikely that they are using a shared hosting provider.
