The Teams alternativethat belongs to you
Chat, meetings and files, just like in Microsoft Teams. It all runs on open source, self-hosted in Germany and the EU. You need no US cloud, and you are not tied to one vendor.
Replaces in Microsoft 365
- Teams chat and channels
- Teams meetings
- OneDrive, SharePoint and Office Online
- Exchange Online and Outlook
- Microsoft Entra ID
- Teams Phone (in development)
What Teams does today, and what replaces it
Microsoft Teams is more than a chat. It bundles meetings, phone calls, files and sign-in. So a Teams alternative has to cover all of these jobs. SecTepe.Comm does this with proven open-source software under one single sign-on. With email, files and office apps, it also replaces large parts of Microsoft 365 and Office 365.
| Job | In Microsoft 365 | In SecTepe.Comm |
|---|---|---|
| Team chat and channels | Teams chat | Matrix chat with Element. Channels, threads and file sharing. Direct messages are end-to-end encrypted by default. |
| Meetings and video | Teams meetings | Jitsi Meet in the browser, with no plugin. With screen sharing and recording. |
| Meeting rooms | Microsoft Teams Rooms | Meeting room module: a mini PC with a room calendar. It joins Jitsi, Element Call, Zoom and Teams meetings with one touch. You need no Teams Rooms license. |
| Telephony | Teams Phone | In development. Telephony on Asterisk. Click-to-dial and screen pop are built but not rolled out. Extensions, queues and voicemail are planned. |
| Files and office | OneDrive, SharePoint, Office Online | Nextcloud with Collabora Online. It opens Word, Excel and PowerPoint files. |
| Email and calendar | Exchange Online, Outlook | Your own mail server with webmail, calendar, contacts and mobile sync. |
| Wiki and knowledge | Loop, SharePoint pages | SecTepe Wiki. Several people write on one page at the same time. |
| Sign-in | Microsoft Entra ID | Keycloak SSO with MFA. It can link to your Active Directory. |
Why teams switch from Microsoft Teams
Most companies do not switch because Teams works badly. They want control over how they talk and share again.
Data stays in the EU
SecTepe.Comm runs in your data center, with an EU provider of your choice or in the sovereign EU cloud run by SecTepe. Your data leaves the EU only if you explicitly ask for it. There is no access under the CLOUD Act and no hidden telemetry.
Open, not locked in
Chat, video and files rest on proven open-source parts. They use open standards such as Matrix, WebRTC, IMAP and CalDAV. You can check the source code, and you are not tied to one vendor.
Security is built in
The platform includes single sign-on with MFA and end-to-end encrypted chat. It also ships a SIEM, a web application firewall and a mail security gateway. You get enterprise-grade security without enterprise license prices.
Chat, video and phone in detail
Here is what each service does and which software runs it.
Matrix · Element
Team chat instead of Teams chat
Group and direct chats with channels, threads and file sharing. Direct messages are end-to-end encrypted by default. Through Matrix federation, you can also chat with partners on their own Matrix servers. You need no guest accounts in your system for that. Federation is off by default, and you approve partners one by one.
- Apps for web, desktop and mobile
- Federation with approved Matrix servers
- Sign-in with SSO, no extra account
- Bridge to Teams chat in preparation
Jitsi Meet
Meetings that also replace Zoom
Video meetings run right in the browser over WebRTC. Outside guests need no plugin and no account. Your team signs in with single sign-on. So SecTepe.Comm replaces Teams meetings as well as Zoom or Webex.
- Screen sharing and recording
- Lobby and moderation
- Apps for iOS and Android
- Sign-in through Keycloak
Asterisk · in development
Phone calls without a Teams license
We are building telephony directly on Asterisk. The core is built and tested, but not rolled out yet. You cannot make calls with it today. Desk phones will use TLS and SRTP for encryption. Read the current status on telephony on Asterisk.
- Built: click-to-dial and screen pop
- Built: TLS and SRTP for desk phones
- Planned: SIP trunks and voice menus
- Planned: queues and voicemail
How to move from Teams to SecTepe.Comm
We guide the migration. We set up single sign-on, mailboxes and shares so your team keeps working without a break.
- Pick how you run it. On your own servers, with an EU provider or in the sovereign EU cloud run by SecTepe. We can run it for you, or you run it yourself.
- Connect your identities. Keycloak becomes your central login with MFA. If you have an Active Directory, everyone signs in with the account they already use.
- Move your data. Email, calendars, contacts and files can be moved over from Microsoft 365.
- Start small, then grow. You begin with the core suite. Add modules such as appointment booking, meeting rooms or e-signature at any time, without switching systems.

How we work with you
We see every project as a long-term partnership, not a one-off delivery. Our approach has four clear phases. So you always know what happens next, who is in charge of what and which results to expect.
1. Free initial conversation
We learn about your starting point, your goals and your constraints. In 30 to 45 minutes we check whether our offer fits your situation. We outline possible paths and answer your questions, with no obligation.
2. Structured assessment
We record the current state: technical, organizational and regulatory. You get a prioritized assessment that names strengths, gaps and areas for action. It is the basis for a reliable offer.
3. Delivery with a dedicated lead
An experienced lead guides you through the delivery. You get clear milestones, transparent planning of effort and cost, and a weekly status. All results are documented and belong to you.
4. Continuous operations & review
After the project, we stay with you in operations. This includes managed services, regular reviews and tracking of open actions. We also reach out when new threats, new rules or technology changes come up.
