Communifire is an Enterprise Social Collaboration platform, a more effective alternative to email and traditional intranets and a great way to reduce time spent in meetings. Empower employees to share ideas and collaborate on content while still retaining control over who can do and see what. Bring partners and customers in and limit them to just what they need to see to work closely with you. Everything a group needs is in one place with updates on all your groups coming to you in one place.
Communifire might be a bit more popular than dotCMS. We know about 1 link to it since March 2021 and only 1 link to dotCMS. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
I am 100% biased, but I would recommend dotCMS (dotcms.com). They are an excellent platform for managing massive amounts of content, and I know a few news sites use them, including some of Thomson Reuters' sites. I know there are a lot good CMSs on the market but this is my $0.02. Source: about 1 year ago
