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

Your company can choose the best installation option to keep your data under your exclusive control.

MORE SECURITY

Slack is simply not designed as a secure collaboration platform suitable for team chat in a large business.

It owns your data and stores it in its own servers. This makes it possible for Slack employees or hackers to access your data without your awareness.
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 FUNCIONALITY

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

While Slack delivers these, Messagenius helps your team function better with a wider range of features. With us, you have private messages, special alerts, smart filters, admin features and more. We also offer tailored workflows built for your use case to enable effective and automated mission-critical communication.

MORE CUSTOMISATION

Slack is Slack, and none of your team members work for Slack. Why should they spend their days working in a Slack environment? Messagenius is a completely customisable collaboration tool for your team. You can build in your branding, features you need, and control access at all levels.

Private On-Premises or Cloud Installation

No matter what type of installation you choose, Messagenius guarantees that your enterprise data is safe. We focus on clear data ownership, security, and enterprise privacy.

Here are your installation options:

  • On-premise, on your enterprise private server for complete data ownership and physical security.
  • On your enterprise private cloud, where you retain data ownership and enjoy the efficiency of cloud operations.
  • On a Messagenius cloud server created and dedicated to your sole enterprise use.

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

FULLY TRACKED & INDELIBLE

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

TEMPORARY & SELF-DESTRUCTING

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.

F.A.Q

What are the alternatives to Slack?

While there are alternatives to Slack, Messagenius is the best option for larger businesses and enterprises. Messagenius offers video calling, team conversations, collaboration features, and advanced options suitable for a communication tool for large organizations. Here are more reasons to choose Messagenius:

  • Unlimited users
  • A completely searchable message history
  • Chat rooms for focused team productivity
  • Internal communication tools for managers

Your managers can have full control to create groups, set security settings per user, allow or block public channels, and manage multiple teams easily.

Can Slack be self hosted?

No, Slack cannot be self-hosted. This is another reason enterprises must consider Slack alternatives. The free version of Slack is not scalable enough for large businesses and the paid versions are simply not secure enough. Messagenius is a fully self-hosted alternative to Slack that gives your organization all the tools you need in a collaboration app while allowing you to run it from your own server.

Is there something better than Slack for my team members?

Boost your team collaboration by using the best of the Slack alternatives: Messagenius. Instead of a busy, crowded team chat, your chat tool could be focused on the important messages every day. Use a team communication tool to send messages to everyone at once. For extra sensitive conversations, use the Black Box or Black Hole features to keep your messages totally secure.

Can Slack be deployed on-premise?

No, Slack cannot be deployed on premise. This is one of the big reasons why your enterprise may need an alternative to Slack. Deploying your team chat tool onto your own servers adds an extra level of protection. When you deploy a team chat app on your own premises, you can also have much more control over any data ownership issues for GDPR and national data law compliance.
