Messagenius: A Microsoft Teams Alternative Designed for Enterprises


Self-hosted Microsoft Teams alternative for secure communication and collaboration across your entire team

Messagenius is the most comprehensive and secure enterprise messaging tool available. It provides more security, better user access control, and improved administrative features. Your company can choose the best installation option because the cloud is not always safest.

Why Does Your Company Need a Microsoft Teams Alternative?

Use of Microsoft Teams has more than quadrupled since the period prior to the Covid-19 pandemic. Millions of users are turning to Microsoft Teams for their collaboration on a daily basis. So, why does your business need to look for a better alternative to Microsoft Teams?

Let us show you three simple reasons why Teams is not your best choice.

More Security

The most significant problem with Teams, and similar, is loss of data ownership. Microsoft and its employees have access to your data because it is stored on their premises.

For truly secure enterprise messaging, you need an on-premises solution. You can, and should, own your data and no one else should have access to it.

More Functionality

Here are the things everyone expects from their messaging app: video conferencing, document sharing, file sharing, team chats, collaboration tools.

While Microsoft Teams delivers these, Messagenius helps your team function better with a wider range of features.

More Customisation

Your employees do not work for Microsoft, so why do they need to spend their time in a Microsoft environment? Other collaboration apps offer far more customisation and integration options than Microsoft Teams.

Being a tailored corporate white-label app, Messagenius gets fully customised for your use case, and provides your colleagues with a tailored app.

White-Label App

Keep your app's user experience and interface in sync with your brand identity. Get a custom private messenger that reflects the values and vision of your organization.

Customisable Encryption Settings

Messagenius offers highly granular security settings. This means you can customise the encryption, user access, and file sharing according to your business needs for every member. Learn more

Own Your Data with
Private Encryption Keys

Messagenius operates a unique encryption key system. We hand over the encryption keys to you, and from then on, no one has access to your data except you.

As an extra layer of protection, we allow enterprises to have multiple holders of encryption keys. Splitting control minimizes the risk for data leak.

Secure Your Chats with Advanced Conversation Protection Features

Some people, meetings, and content need an extra level of protection. When your organization needs to move to a higher level of privacy, we have two kinds of chats to protect your people.

Black Box Chats


Know when, what, and to whom all the conversations have been sent within your enterprise. Messagenius Black Box Chats are always certified between sender and recipient. All messages are time stamped and come with a mandatory proof-of-receipt.


Black Hole Chats


Protect your most sensitive data with Black Hole chats. Messagenius Black Hole conversations do not pass through any servers and leave no trace of their existence. Set up a timer, and once your message is open, the message always self-destructs and cannot be recalled from the server.


Achieve GDPR Compliance with Full Data Ownership and Clear Data Sovereignty

Messagenius is 100% compliant with GDPR and leak proof. We do not involve third parties to store, access or use your data. Even the team at Messagenius itself does not have access to your data. The requirements include:

Privacy by design

From the beginning, Messagenius has been designed to protect your data at the individual and enterprise level.

Transfer of data

Messagenius gives you complete control over where and how your data is stored.

Messagenius gives organizations a platform for secure business storage of data and compliance with every GDPR statute.

Get Up and Running Smoothly with Seamless Integration with Existing Software

Are there free alternatives to teams?

Yes, there are over 100 free alternatives to Teams. However, a large enterprise needs more than a small alternative. The completely free options lack key features, and the alternatives with all the features are not free.

Can you use Microsoft teams as an intranet?

Microsoft Teams is trying to achieve more intranet functionality, but it is not there yet. Third party apps are still being used to fulfill intranet functions alongside the collaboration tools offered by Teams.

Can external parties use Microsoft teams?

Yes, team leaders can invite guest attendees to meetings or to join a team. Guest users gain access to the chats and files being shared by your team members. While guests can view meetings, they could also gain access to sensitive information or private communication.

Are Microsoft teams self-hosted?

No, Microsoft Teams is not available as a self-hosted solution. For the ultimate in data ownership and privacy, you need a self-hosted solution such as Messagenius.

Is Microsoft teams available on premise?

No, Microsoft Teams is designed to function with SharePoint Online and the Azure Active Directory. While it may be possible to gain some functionality in a hybrid environment, the full features of Microsoft Teams are not available in an on-premises installation.

Can Microsoft teams be hosted locally?

No, Microsoft Teams works with Exchange and SharePoint Online. These are cloud hosted apps and not available as on-premise tools. This is because Teams aims to work together with Skype, Outlook, OneDrive for Business, and all the standard Microsoft Office apps.

Does teams use Active Directory?

Yes, Teams works through Azure Active Directory. This provides the necessary sync function for keeping people and workflows in sync.
