# Confidential Communications — sovereign email, chat and calls, built with your own teamA mid-size or regulated company brings its confidential communications in-house — sovereign email, end-to-end messaging and calls — built with its own staff (no tender), OSSTMM-assessed and run under an ISO 27001 / BSI ISMS.

A mid-size company — a law firm, an engineering office, a regulated supplier — concludes that its confidential email, chat and calls should not sit on third-party SaaS, where the provider has visibility and custody. It has its own IT staff, so the route is not a tender but a **service build-up with its own team**, with Pronix fractional alongside.
