Many of you may already know this, but as of March 15, 2017 NetSecFocus decided to migrate our community to our own Mattermost server. There were a few reasons for this with the main reasons being message retention in Slack. At our volume messages were only lasting for a maximum of 10 hours which made it impossible to search for anything meaningful. Due to this and the impossibility of paying about $12k USD/month for Slack we decided to ditch it for something better.
After many months of testing various chat platforms, we decided Mattermost was the best compatible for us. Since it's open source, we could also make some customizations that make it fit us even better than Slack ever will.
On March 24, 2017, we deleted our old Slack workspace. RIP
