Self-Hosted Contact Management — Why Data Sovereignty Matters

For Swiss and European businesses, where your contact data lives isn't just a preference — it's a compliance requirement. Here's why self-hosted matters.

When a Swiss financial advisor stores client contacts in a US-based SaaS tool, they face a fundamental problem: the data is subject to US law, not Swiss law. For many industries, this isn't just uncomfortable — it's a compliance risk.

The Problem with Cloud-Only Contact Management

Most modern contact management tools are cloud-only SaaS: your data lives on someone else's servers, in someone else's country, under someone else's legal jurisdiction.

For general business use, this is often fine. But for:

  • Financial services:Client data subject to banking secrecy (Bankgeheimnis) and FINMA regulations
  • Legal firms:Attorney-client privilege extends to contact data
  • Healthcare adjacent:Patient contact information under data protection regulations
  • Government contractors:Data residency requirements in tenders
  • Any Swiss/EU business serious about GDPR/DSG:The question "where exactly is my data?" must have a clear answer
  • ...cloud-only tools create an uncomfortable gray zone.

    What "Self-Hosted" Actually Means

    Self-hosted doesn't mean running servers in your basement. It means:

  • Your infrastructure:The software runs on a server you control — your office server, your data center, or your Swiss cloud provider (e.g., Exoscale, Infomaniak, Swisscom).
  • Your jurisdiction:Data stays in Switzerland (or wherever you choose). No cross-border transfers.
  • Your access:No vendor has access to your data. No "we'll export it for you" — you own the database directly.
  • Your updates:You decide when to update, after testing. No surprise changes on a Friday afternoon.
  • The Best of Both Worlds: Managed or Self-Hosted

    Not every organization wants to manage their own infrastructure. That's why the ideal solution offers a choice:

  • Managed hosting:The vendor operates the instance for you — updates, monitoring, backups — but on infrastructure you approve and in a jurisdiction you choose.
  • Self-hosted:You run everything yourself. Full control, zero dependency.
  • The key is that the choice exists. Cloud-only vendors don't give you this option.

    How Contact Central Approaches This

    Contact Central is designed for both deployment models:

  • Managed by Solvia:Solvia GmbH (Forch, Switzerland) operates your Contact Central instance. Data stays in Switzerland. Updates and monitoring included. CHF 50/month.
  • Self-hosted:Download, run the setup wizard, and deploy on your own server. Linux or Windows. No cloud dependency. No hosting fees.
  • Both models include:

  • Encrypted credentials:Azure AD / Entra ID secrets stored with ASP.NET Core Data Protection API.
  • Certificate-based authentication:For Exchange connections — no shared secrets needed.
  • Role-based access control:Admin, Manager, User — everyone sees only what they should.
  • Complete audit trail:Every change logged. Who, what, when. 70+ event types.
  • Database backup/restore:One-click backup and restore from the admin panel.
  • When Self-Hosted Makes Sense

    Self-hosted is the right choice when:

  • Your industry has data residency or data sovereignty requirements.
  • Your IT team prefers full control over updates and infrastructure.
  • You want zero dependency on external vendors for data access.
  • Your compliance officer needs to point to a specific server and say "the data is here."
  • When Managed Hosting Makes Sense

    Managed hosting is the right choice when:

  • You don't want to manage servers, updates, and monitoring.
  • You trust the vendor but want data to stay in Switzerland.
  • You want professional operations without hiring an admin.
  • You're a small team that values simplicity over control.
  • Either Way, Your Data Stays Yours

    The most important thing isn't where the server is — it's that you have a choice, and that the vendor doesn't hold your data hostage. Contact Central exports to CSV, provides a full REST API, and keeps the database on your infrastructure (or Solvia's, transparently). Moving away is always possible.
