Every conversation you have, file you share, and message you send is cryptographically secure. Encryption is a business imperative. Protect your ideas, intellectual property and trade secrets with Semaphor. Until now, there's never been a mainstream product that brings you usability, convenience, and security. Think of this as a private alternative to Slack and Hipchat. We build all of our products with Zero Knowledge privacy. This means we know nothing about your data (even metadata) and everything stored on our servers is in blocks of cipher text. We store nothing in plaintext data and couldn't access anything of yours even if we wanted to. This is what sets us apart from the other hosted collaboration tools and chat applications on the market. What else?
