Top 7 open source messaging platforms for secure communication (2024)

For remote teams, connectivity and productivity might be two faces of the same coin. Working from the office isn't a prerequisite anymore, as the global workforce has shifted to a remote workplace. Reliance on internal communication has increased more than ever, with a wide range of communication tools such as email, phone calls, and social networking used daily.

Long email threads and social media chats are no longer appropriate for business teams. Hence, organizations rely on messaging platforms to work remotely and stay up to date to boost productivity. In contrast to email and other options, teams now need intuitive and user-friendly tools such as instant messaging platforms.

Such platforms provide fast, real-time communications for teams across the globe. Some teams are looking for higher levels of flexibility and security in their communication tools: thus, they opt for open source messaging platforms.

In this blog, we’re going to outline some of the best features of top open source messaging platforms for secure and effective communication.

Why go for an open source messaging platform?

Yes, you need a communication platform: but why should you choose an open source one?

In general, open source software does not adhere to the standards of off-the-shelf software and provides an additional set of benefits.

Business-oriented open source messaging caters to organizations requiring customizations based on various admin controls, compliance to industry or region-specific regulations, and more.

Some of the reasons to adopt an open source platform include:

1. Transparency

Open source equals transparency: since everybody can see the code running in the back of the tool, there isn’t hidden misuse of certain features or inappropriate handling of your data.

You know everything that goes on under the hood!

2. Flexibility

Open source messaging platforms provide the feature to customize the code and adapt it to the business's own needs. The digital environment across organizations differs, with some needing higher regulations and security.

For example, organizations in highly regulated industries such as healthcare, education, and government often need to tweak the software they use to fit their exact needs. With open source, this is simple.

3. Security

The security compliance requirements of different organizations may vary. With open source projects, organizations can rely on code improvements from numerous contributors in the community. One of the advantages of open source messaging platforms is the Increased security of the source code. This is due to a larger audience noticing and fixing the vulnerabilities faster.

4. Cost efficiency

There are paid and free open source chat platforms available, and the organization can even try the free plans before implementing them daily. Compared to market leaders such as Slack, open source platforms allow organizations to customize the features they require while optimizing them cost-efficiently.

5. Avoiding vendor lock-in

Opting for a particular provider or vendor can make organizations feel trapped and comply with their terms, leading to a lock-in of budget, labor, and time. With open source messaging platforms, there's no boundary of a vendor's ecosystem, and the organization can scale up, down, or customize the features per their requirements.

How to choose your team chat?

Before you choose a platform that's been the talk of the town, it's best to make an informed decision. Choosing the right messaging tool for your organization can pay off in the long run. Before making a decision, here are some key features to evaluate:

1. Look for an intuitive user interface

2. Check the support quality- do they cater to queries and provide support to users?

3. The ease of deployment and management of the solution

4. Look for integrations- does it fit or support your current tech stack? Is it feasible for your team in the long run?

5. Security orientation - if your organization requires specific compliances, ensure that the solution has strong security features to be deployed on-premise

Before acquiring an open source messaging platform for your organization, ensure that your requirements align with their priorities. Data protection, security, support, and seamless usage should be important aspects to consider before making a purchase.

So.. what are you waiting for?

Open source messaging platforms bring their own set of advantages to organizations in different industries. We would say that they don’t lack in features compared to market leaders - but they do bring on an extra layer of security and flexibility that’s needed in some cases.

It doesn’t hurt that most open source solutions are cheaper than their proprietary counterparts - and that they can be deployed on-premise so your organization can maintain full control over exchanged data.
