# Troop Messenger > Troop Messenger is an enterprise-grade secure team messaging and collaboration platform available as SaaS, On-Premise/self-hosted, and fully air-gapped deployments. Built by Tvisha Communications, it delivers end-to-end encrypted chat, audio/video calling, file sharing, PQC VPN and AI-assisted productivity, with role-based access controls (RBAC), audit logs, LDAP/SSO, and complete data ownership for organizations that cannot compromise on security or data sovereignty. Troop Messenger serves enterprises, startups, and high-trust or regulated sectors — including defence, government, BFSI, shipping, and NGOs — across 30+ countries. It is trusted by organizations such as the Indian Air Force, the European Space Agency (ESA), Airbus Defence and Space, and the UK Ministry of Defence (UKHO). Three deployment models are offered: SaaS (cloud-hosted), On-Premise (self-hosted on the customer's own servers), and Air-Gapped (offline/intranet-only for classified and isolated environments). Paid plans start at $2.5/user (Premium) and $5/user (Enterprise), with a free 7-day trial. ## Core pages - [Home](https://www.troopmessenger.com/): Overview of Troop Messenger as a secure, AI-first team messaging and collaboration platform. -
