Comments about Slack as a Alternative to Semaphor
pros, cons and recent comments
John Fastman
Semaphor is built around zero-knowlege encryption to prevent their parent company employees, government agencies and hackers from getting at user data. Slack is nothing like as secure or private because they don't build in such encryption. Other encrypted products in this space are Stackfield and Peerio.
