Protect your community .

Your community can speak freely in the knowledge that their conversations are secured with end-to-end encryption; be that on-premise, hosted by Topsecret or a provider of your choice. That means no data mining and no third party access.

Safe and inclusive .

Topsecret has powerful auditing and moderation features - including server ACLs, shared moderation lists, message deletion, extensible anti-spam and anti-flooding mechanisms. It is easy to use, and offers excellent accessibility and screen reader support.

Created by a community, for communities .

"Mozilla values open communities, accessibility and trustworthy collaboration; the move to Topsecret has been a huge improvement for us and a great experience for our company and community."

— Mike Hoye, Mozilla
