Mattermost FAQ

Answers to the most important questions

Topics

General

Mattermost is an open-source messaging and collaboration platform for teams. It offers channels, direct messages, file uploads, integrations and enterprise features like compliance exports and playbooks.

Yes. We handle setup, operations and maintenance (updates, monitoring, backups, incident handling) – so you can use Mattermost productively without building your own ops resources.

Both are possible: on our infrastructure (e.g., Germany, other locations) or on your infrastructure (on-prem / your own cloud account) – depending on requirements for control, network connectivity and processes.

Mattermost supports PostgreSQL and MySQL as databases. For production, we recommend PostgreSQL with appropriately configured setup (connection pooling, backups, replication if needed).

Operations & SLAs

Yes. We set up automated backups and plan (depending on package) regular restore checks, so recoveries don't remain "theoretical" in case of emergency.

Typically in 4 steps: (1) Requirements & user count, (2) Target setup (domains, SSO, policies), (3) Deployment + baseline hardening, (4) Handover + operations (monitoring/backups/updates).

Yes. We can set up separate environments (e.g., staging for updates/tests and prod for live) – with separate instances, domains and access concepts.

Typically included: Provisioning + hardening, updates & patch management, monitoring/alerting, backups/restore, incident response and ongoing operational tasks (e.g., scaling as agreed). Details are package-dependent.

Yes. We agree on maintenance windows (e.g., outside your peak times), test changes (optionally first in staging) and announce plannable updates in advance.

Yes – depending on needs, we set up HA architectures (e.g., multiple app servers behind a load balancer + replicated database). Mattermost Enterprise supports clustering for high availability.

This depends heavily on user count, message volume, uploads and features. Mattermost provides sizing guides for this; we size an appropriate setup from it (and scale later).

Typically technical metadata like metrics, logs, alerts (e.g., utilization, error rates) are generated. We can set up monitoring to match your requirements (e.g., "only in region X", defined retention). What exactly is captured is documented transparently.

Security & Auth

Mattermost supports multiple auth methods: local accounts, AD/LDAP, SAML 2.0, OAuth 2.0 (GitLab, Google, Office 365) and MFA/2FA.

Yes – we help with technical configuration (IdP parameters, attributes, group sync, role mapping) and continue to operate the environment stably.

Yes, Mattermost supports MFA (Multi-Factor Authentication) via TOTP apps like Google Authenticator or Authy.

Standard baseline: least privilege, separate admin roles (System Admin, Team Admin), 2FA/SSO, IP/VPN access (optional), logging/monitoring and defined processes for changes and incidents.

Yes. Mattermost Enterprise offers compliance exports, message retention policies, custom terms of service and audit logs. These features are particularly relevant for regulated industries.

Features & Integrations

Playbooks are structured workflows for recurring processes like incident response, onboarding or release management. They include checklists, automations and can be linked to channels.

Yes. Mattermost supports incoming/outgoing webhooks, slash commands and has an app marketplace with integrations (Jira, GitHub, GitLab, Jenkins, etc.). We help with technical connection.

Yes. Mattermost offers native apps for iOS and Android. For self-hosted instances, push notifications can be configured via the Mattermost Push Proxy or your own HPNS (Hosted Push Notification Service).

"I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us."

"Counting on WZ-IT team was crucial, their expertise and solutions gave us the pace to deploy in production our services, even suggesting and performing improvements over our configuration and setup. We expect to keep counting on them for continuous maintenance of our services and implementation of new solutions."
"

Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)

"

We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)
