April 25, 2026

Use Cases and Deployment Scope

We use Mattermost as our internal communication and collaboration tool across different teams. As our teams are based globally in different time zones and operations are occurring at multiple locations working in different schedules, Mattermost helped us in reducing communication gaps. It gives us a centralised platform where information doesn’t get lost in long threads of emails.

Pros

Keeps communications well organised
Good integrations and automations such as alerts, bots and workflows
Reliable for real time collaboration and incident handling
Offers strong security and self hosting options

Cons

Filters and indexing could be more precise and faster
Video calling and built in meeting features aren’t as strong as other dedicated tools
Mobile app performance and syncing aren’t always as smooth as desktop version

Likelihood to Recommend

Mattermost works really well in situations where structures, fast communication is critical such as day to day project coordination. We use dedicated channels for different workstreams which makes it easy to keep discussion s focused and searchable. <div>

</div><div>Mattermost is less suitable for formal external communication with clients or stakeholders where email or dedicated client faced tool is more appropriate. </div>

Mattermost is a great Air Gapped messaging solution

March 27, 2026

Use Cases and Deployment Scope

Mattermost was the best option of multiple options we tried to replace skype within an air gapped development domain since we cannot use Teams. It was simple to install and update and maintain on our own hardware. Some platforms required you to build a container and we would have to transfer it over and it was getting very difficult to update. This is just on our web server and super easy to maintain in an air gapped environment.

Pros

connect to gitlab for authentication
simple air gapped install
just like any other messaging platform

Cons

No suggestions it's pretty easy to work with

Likelihood to Recommend

Mattermost was the best platform we've tried that could replace Skype in an air gapped environment where we cannot use Teams.

Mattermost helps my company where it matters MOST.

March 23, 2026

Use Cases and Deployment Scope

Mattermost is super helpful when dealing with secure contracts. Especially with military, government, and/or municipal jobs. Keeps information protected and limits access to the ones who "matter most" to the project (no pun intended). This has helped us secure more government contracts and keep confidential information confidential.

Pros

Security questioning.
Secure accessibility.
Customer service.

Cons

Chat support.
More manufacturer specific organization.
Integrated CRM.

Likelihood to Recommend

Mattermost is well-suited for customers looking to work with the government or public organizations (i.e., municipalities, military, schools, etc.). However, Mattermost may not be the best fit for businesses that primarily deal with individual customers. Business-to-business users may find it helpful, but it really seems aimed towards government work.

Mattermost User Review

Rating: 7 out of 10

August 9, 2024

Use Cases and Deployment Scope

We handle a lot of PII for our customers since we run credit checks and also access their mortgage information. We want to have a secure way of instantly and securely share documents to different members of the team, especially those who are on site or working from home. Most of the mesaging apps do have that feature but I guess because of the number of users we have experienced significant delays in sending messages.

Pros

Easy intergration to our main CRM (Monday.com)
I'm not techy myself but I have seen a lot of our previous integrations in Slack transferred over to Mattermost so that's fun
The desktop and phone app (android) works well enough. I haven't tried it on the Apple ecosystem yet.

Cons

We just use it for file sharing and messaging, it was not so hard to transition to it from Slack. The app is laggy sometimes, but that is to be expected I guess.

Likelihood to Recommend

I think if you are starting out in messaging apps like this, it's a pretty great start. User friendly and easy to navigate. However if you're used to a certain messaging environment it may not work for you because it's not really heavy on features. I like that about it though, because it's strictly a business messaging app.

Use Cases and Deployment Scope

I use Mattermost mainly for team communication and colabs such as messaging, file sharing, and project management. It's most helpful for file sharing while being remote.

Pros

Threaded conversations that keeps discussions on specific topics organized and prevent important information from getting lost in a stream of messages.
Integration with tools like Office 365 for file sharing and collaboration
clean, intuitive user interface that is easy to navigate

Cons

Advanced search could be better and it seems a bit slow
audio and video conferencing tools could be better
more granular control of notifications

Likelihood to Recommend

Mattermost is well suited for medium sized remote orgs but I think may be overkill for smaller orgs

Pros

collaborate within organization
open discussion within the organization or department

In our company, we use Mattermost to let everyone know whenever any incidents happen. Additionally, within the team whenever we have questions and are looking for answers, we can start a thread and talk with multiple people at the same time.

Mattermost is great for collaboration and communication

Rating: 8 out of 10

August 7, 2024

Use Cases and Deployment Scope

It supports the communication aspect of project management. The collaboration of the teams and management is the most important in an organization and it's best in cases of multiple teams and bigger projects because it helps in WBS.

Pros

Team Collaboration
Communication
Multi Platform Support
Security
Screen Sharing
Self Hosted
Desktop and Mobile App

Cons

Call glitches sometimes
Limitations on File Sharing
UI can be improved although it's simple for new users
Its own video conferencing has limitations of users
Search feature can be made better

Likelihood to Recommend

We use Mattermost for team communication. When it comes to the call where you require you cannot have everyone on the call, because it has limitations and it requires some work and glitches with the conversation. But overall it can do well when it comes to aligning your projects and updates.

A secure alternative to using Slack and Teams

Rating: 7 out of 10

August 1, 2024

Use Cases and Deployment Scope

Our organization is trying to achieve SOC 2 compliance right now. Many of our clients are government contractors, so it is imperative that passwords and government information is not leaked. We tested it with just a handful of employees at first to see how easy it would be to deploy on-prem. The main idea was to have a communication platform that is more secure to achieve compliance.

Pros

It can be deployed to a secure on-prem Linux Server
It meets many of the checklists for Cybersecurity Insurance
The ease of use for new users is good. The layout is self-explanatory

Cons

There is no free version to at least try out the service
The cost is much higher than using the Microsoft equivalent
We could not find a way to communicate over video using the platform

Likelihood to Recommend

If you are an MSP that is looking to become a MSSP, this is a product to consider. You can run the application on a Linux server that is in your datacenter. From there, you can lock down the server so that it can only be accessed from an internal IP versus having an external IP open to the world. This makes it easier to prove you are SOC 2 compliant and able to complete the Insurance Cybersecurity checklist for Government clients. It is not appropriate for just an alternative to Teams that will be cheaper.

Mattermost is what matters most!

July 31, 2024

Use Cases and Deployment Scope

Mattermost is very beneficial when you have departments that collaborate on internal documentation together. There are many features in addition to that but the most important one, for us, is a central hub designed to bring our departments, tools, and information to the rest of the organization. Very useful tool.

Pros

Sharing Information
Securing Information
Coloration on Information

Cons

UI is very technical
Simple Layouts can be introduced
Internal Sharing via Public Link

Likelihood to Recommend

Mattermost is all dependent on what type of organization you are apart of. Yes it is good for internal documentation and collaboration, however, if you do not rely on a space to collaborate on then this might not be a tool you acquire however if you have multiple departments collaborating on information, then it is worth exploring.

Stellar internal communication and all-in-one task workflows tool!

Rating: 9 out of 10

July 22, 2024

Use Cases and Deployment Scope

We use it as our internal communication tool / main messaging platform. We find it to be a very flexible tool that we can adjust for the specific needs of our organization. We use it for all things communication and basically only use email for outside parties. I think it is so much better than microsoft teams and other tools like that!

Pros

Messaging
Saving Messages for Later
Sharing files

Cons

maintentance (since it's open source IT needs to invest more in keeping it in good shape)
third party integrations (less features than slack)
It's a little less visually polished than big tech platforms

Likelihood to Recommend

It's really great if you want more control of the tool to abe able to customize it to the needs of your specific organizations. Sometimes off the shelf options don't work for all orgs.
