Managed team chat on Mattermost

Mattermost gives your organisation channels, direct messages, calls and file sharing, the way the big chat services do. We run it for you on a dedicated instance with your own domain, in a datacenter we operate, so every message and every file belongs to you and nobody else can read it, mine it or switch it off.
What it is
A private Mattermost instance that is yours alone. Not a tenant on a shared platform, not an account on someone else's service. Your domain on the address bar, your users, your teams, your retention rules, your data on disks in Athens, Amsterdam or Toronto.
We install it, secure it, back it up, watch it around the clock and keep it current. Your people just use it. Your administrators keep full control of teams, channels and users from the system console, and we stay behind them for everything underneath.
How we build it
Every instance runs on Oracle Linux with PostgreSQL, SELinux enforcing, behind firewalls we own and operate. Open sign up is closed at hand over, so only the administrators you name can bring people in.
Network exposure is a decision, not a default. We can restrict access to the countries your team actually works from and refuse the address ranges of cloud and VPS providers where scanners live. After every change to that policy we test it from several countries, from the outside, the way an attacker would.
Upgrades are a process, not a button. Major releases go onto our own instance first and run there before they reach yours.
Moving in is part of the service. If you already run Mattermost somewhere else, we can bring it across with its history, files and users, and we count what arrived against what left before we call it done. Teams and channels can also be moved between instances with the same verification.
If you want live chat on your public website as well, we run Chatwoot alongside it on the same terms: self hosted, your data, your domain.
What it protects you from
- A chat provider that can read your conversations, change its terms or close your account.
- Confidential discussions, legal or commercial, sitting in another company's cloud under another country's rules.
- An "update to latest" that installs the wrong release branch, or one that will not start on your server.
- An upgrade that quietly breaks on a dependency nobody checked.
- Scanners and bots knocking on a platform that only your staff should ever see.
- Losing years of history when you change hosting provider.
In practice
For a managed services partner we built a dedicated instance on their own domain, with closed sign up and their administrators in place on day one. We then moved their working channels across from an existing chat platform, history and attachments included, verified message by message, without disturbing either side.
When Mattermost published its latest major release, our own production instance went first; customer instances followed once it had proven itself there.
Why EuroVPS
- A dedicated instance per customer, never a shared tenant.
- Your data stays in a datacenter we operate, in Athens, Amsterdam or Toronto, on enterprise all-flash storage, under a backup plan that pulls from the platform and never the other way round.
- Firewalls, country policy and scanner blocking we own and verify from the outside.
- Engineers who run Mattermost for their own company every day, not a ticket queue reading a vendor FAQ.
FAQ
Can we use our own domain and our own branding? Yes. The instance answers on your domain with your certificate, and your administrators control the workspace.
Can you move us from our current chat platform? Yes. Existing Mattermost moves across with history, files and users, verified by count. From other platforms we import what the platform allows you to export, and we tell you up front what that is.
Who can see our messages? Your users. The platform runs on infrastructure we own, it does not feed an advertising or analytics business, and nothing is sent to an outside service.
Do you keep it up to date? Yes, as routine. Security releases are applied promptly after checking; feature and major releases are scheduled with you, after they have run on our own instance first.
Can we restrict where it can be reached from? Yes. Country allow lists, provider network blocks, VPN only access or private network only access are all options.
