Confidential Communications — sovereign email, chat and calls, built with your own team

A 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.

Delivery with your own team

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.

What each stakeholder is really asking

CEO

Why bring communications in-house at all?
Client privilege, trade secrets and sector rules make third-party SaaS custody of your email, chat and calls a liability. In-house, sovereign communications remove that exposure — and become a trust signal to your own clients. → Digital Sovereignty
Our clients trust us already — why invest in this?
Because one leaked thread or a provider breach erases that trust fast. Owning your communications is a demonstrable signal — you can tell clients exactly where their words live and who can read them: no one but you.
Is this only for paranoid firms, or a real business case?
Real: for anyone with privilege, IP or sector rules, third-party custody is a liability and increasingly a procurement and insurance question. It is risk reduction with a side of differentiation, not paranoia.

CFO

Is building it ourselves actually cost-effective?
Yes — you already have the IT staff; we come in fractionally for the hard parts, so you avoid both per-seat SaaS fees and a full external build. Fixed, predictable cost — and the result is an asset you own, not a subscription that compounds.
Won't using our own staff pull them off other work?
We scope it so it does not swamp them — Pronix does the hard parts fractionally while your people learn the system they will run. You build capability and the asset, instead of renting both forever.
SaaS is cheap per user today — where is the saving?
Cheap per user compounds with headcount and never ends; this is a fixed cost you own, with no exit penalty. Over a few years the owned asset wins, and you are not exposed to per-seat price hikes.

CIO

How disruptive is the build, and who owns it afterwards?
Minimal — your own team builds it (with us alongside), so the knowledge stays in-house from day one. Standards-based, integrates with your identity and devices, and it is yours to run. We are on support only if you want it.
Will it work with our identity, devices and existing mail?
Yes — standards-based (IMAP/SMTP, standard identity, native iOS/Android/desktop clients), it integrates with what you have. We migrate mailboxes and federate rather than forcing a clean break. → Sovereign Email Platform
What is our fallback if something goes wrong after handover?
Documented runbooks, your trained team, and an optional support retainer. Open standards mean you are never stranded — you can get help from anyone, not only us.

CISO

How do we know it is actually secure, not just self-hosted?
We measure first with an OSSTMM-style assessment, build default-deny behind a Sovereign Edge Firewall with end-to-end Messaging, and run it under a lean ISO 27001 / BSI ISMS with the Security & Observability Platform watching. Provable, not assumed.
Is the end-to-end encryption real here, or marketing?
Real: the Messaging Platform is end-to-end encrypted and federated, so even you-the-operator cannot read message contents. We can demonstrate the model, not just claim it.
How do we satisfy GDPR for communications data?
Data stays in your perimeter under your control — Art. 28 processor questions largely disappear, and a fractional DPO frames the rest. Confidentiality by architecture, documented for audits.

Project lead

Can my team deliver this without it dragging on for a year?
Yes — we scope it into clear increments your team can execute, pairing on the hard parts and reviewing. A burndown/Gantt, a milestone per service, and the first confidential channel live in weeks — not a year-long programme.
My team hasn't built this before — is that a risk?
We de-risk it by pairing: your people learn on the real system while we lead the tricky parts and review. The plan below sequences it so each channel is live and stable before the next begins.
How do we show progress to management?
A burndown/Gantt and a milestone per service — email, then chat, then calls — each a visible, demoable win, not a six-month black box.

In-house architect

We have strong opinions on how this should be built — will you work with them?
That is the point of the own-team model: your architecture leads, we bring patterns, review and the proven building blocks, and document the decisions. You own the design and the result. → Rent-an-Enterprise-Architect
Will you dump unfamiliar tech our team can't maintain?
No — we favour boring, proven, well-documented building blocks your team can actually run, and we train them on it. Maintainability is a design constraint, not an afterthought.
Can we keep our existing tooling where it is fine?
Yes — we integrate with what works and only replace what creates the SaaS-custody risk. Open standards keep it all interoperable. → Digital Sovereignty

How it runs, end to end

  • The idea — confidentiality you control

    Client privilege, trade secrets or sector rules make third-party custody of communications a risk. The company wants its email, chat and calls in-house — without a heavyweight programme. See Digital Sovereignty.

  • Measure first (OSSTMM)

    A fractional Security Officer runs a measurable OSSTMM-style assessment of the current exposure, and a DPO frames the GDPR obligations — so the build targets real risk, not a vendor catalogue.

  • Build with your own team

    No tender needed: the company’s own IT builds the stack, with Pronix fractional alongside for the hard parts and review. Sovereign Email, end-to-end Messaging and Voice & Video, with a Certificate Authority for internal trust.

  • Secure it — default-deny

    Everything sits behind a Sovereign Edge Firewall, default-deny and segmented, with the Security & Observability Platform watching for anything unusual. See Security.

  • Operate under an ISMS

    A lean ISO 27001 / BSI Grundschutz ISMS keeps it correct over time — documented, measured, improvable — without drowning the team in paperwork.

  • Handover — the team owns it

    Because the company’s own people built it (with us alongside), the handover is natural: documented, operable, theirs. We stay on support only if wanted.
