I am looking for an extranet in order to also communicate with clients. Do you have any recommendations for me?
Please take a look at our intranet solution Linchpin which lots of clients are using as an extranet: https://www.linchpin-intranet.de/
Addionally we offer an add-on which includes extranet use cases:https://info.seibert-media.net/display/DOC/Space+Guardian+for+Confluence+-+User+and+Administration+Guide+1.0
Base for both is Atlassian's Confuence: https://infos.seibert-media.net/display/landingpage/Confluence+-+Unternehmenswiki,+Intranet,+Social+Collaboration
