  • 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.

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 WebRTC, IMAP and CalDAV. The chat also runs on an open protocol. 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.

Chat

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. You can also chat with partners who run their own compatible chat server (federation). 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 partner servers
  • Sign-in with SSO, no extra account
  • Bridge to Teams chat in preparation

Video

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 single sign-on

Telephony · in development

Phone calls without a Teams license

We are building our own phone system. 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 our phone system page.

  • Built: click-to-dial and caller pop-ups
  • 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.

  1. 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.
  2. Connect your identities. SecTepe.Comm becomes your central login with MFA. If you have an Active Directory, everyone signs in with the account they already use.
  3. Move your data. Email, calendars, contacts and files can be moved over from Microsoft 365.
  4. 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.

More than a Teams alternative

SecTepe.Comm covers the whole digital workplace. These pages tell you more.

Technical foundation

SecTepe.Comm uses proven open-source building blocks: Matrix with Element for chat, Jitsi Meet for video and Nextcloud with Collabora Online for files. Keycloak handles sign-in, and Asterisk is the base of the phone system.

How we work with you

We want to work with you for the long run, not just deliver once. Our way of working has four steps. So you always know what comes next, who does what and what you get.

1. Free initial conversation

We learn where you stand and what you want. In 30 to 45 minutes we check if we are a good fit. We show you options and answer your questions. There is no obligation.

2. Current state review

We check where you stand today: tech, processes and rules. You get a list of strengths and gaps, sorted by urgency. Our offer is based on it.

3. Delivery with a dedicated lead

An experienced lead guides you through the project. You get clear goals, an open plan for time and cost, and a status every week. All results are written down and belong to you.

4. Running and reviewing

After the project we stay with you. We run systems for you, check them at set times and keep track of open tasks. When new threats or new rules come up, we get in touch.
