To some business owners or managers, open-source RMM software means insecure, without standards, and non-compliant systems. They prefer commercial RMM software whose vendor provides security, quality and compliance certifications to gain their customers' and partners' trust and confidence.

But many organizations still choose open-source RMM software over proprietary software. Why? The truth is most lines of code in proprietary software are open-source, and the software can still go under regardless of the effort and finances invested in it. 

For instance, what if the closed RMM software you invested in is sold, bought, or stopped altogether? What if the vendor no longer provides meaningful updates, or the cost of maintaining the software outweighs the value it offers?

This article discusses the benefits and limitations of open-source software as well as the factors to consider when choosing between open-source and commercial RMM software. We also have a list of what we have established to be the best open-source RMM software available.

Control is the key reason many organizations choose open source RMM software

One critical reason many organizations seek open-source RMM software is so they can have greater control. With open-source RMM, you can utilize your internal team of developers or a software development company to create a customized solution for a quarter of the price of a proprietary RMM.

The developers can help incorporate more features to match your business’s remote monitoring and management needs. They can also review the open-sourced code for security, pull audit information and document the audit checks to ascertain the quality of your solution.

Furthermore, open-source RMM software is free. This means organizations, such as MSPs, looking to cut operational costs while reaping the benefits of an RMM can experiment with various open-source solutions to find the best fit.

However, open-source RMM has its downsides in certain circumstances, which necessitate the need for commercial RMM software. 

Benefits of open-source RMM software

The most obvious benefit of open source RMM software is that it comes without the costs associated with proprietary options. This will save you a significant amount of money, but you should not forget the cost of tailoring an open source tool to fit your needs.

The specific benefits include:

Open source RMM software will save you operational costs

You don’t need to invest in buying licenses for commercial RMM software if you do not have the resources to spare. 

Even when you have the money, you do not have to spend on tools that you can also get at a lesser cost to serve the same function. If you only have a few endpoints to monitor, for example, you can comfortably work with open source free RMM solutions. 

Open source RMM software can be customized to meet specific business needs

You can work with an experienced team of developers to add more features. They’ll tweak the software to meet your remote monitoring and management needs.

Community support

Opensource RMM source code is publicly accessible. This paves the way for code review, public critiques, knowledge sharing and collaborative bug fixes. 

This is possible through shared community platforms such as Slack.

Easy to identify and address issues

You can run code review scripts on the open-sourced code to check for any backdoor passwords or vulnerabilities. This allows you to  perform bug fixes for improved quality and security of the software.

Stability

Most open-source RMM solutions have been around for years. The community of users is constantly reviewing and improving the software. Hence, you can count on its stability.

Limitations of open source RMM software

  • Lack of official support: From setting up all the way to configuration and maintenance, open-source RMM software can be complex unless you have an experienced team of developers. Although shared community platforms can be helpful, you can’t count on them for reliability and convenience across all issues.
  • Limited features: An enterprise organization with thousands of endpoints to monitor requires automation and detailed analytics features. Most open-source RMMs don’t support this.

Commercial vs Open source RMM software: What should you consider?

Undoubtedly, leveraging open-source RMM software can improve productivity, cut down IT costs and simplify IT infrastructure monitoring and management. However, commercial RMM software can be more efficient and effective with various considerations.

So should you go between choosing either of these two directions? Consider these factors when choosing between commercial and open-source RMM software:

1. Nature of operations

Critical operations, such as in healthcare systems, demand optimum uptime. Else, they can be life-threatening. 

For such systems, a commercial RMM would be more reliable as it can support advanced technology for over 99.5% uptime.

2. Scope of business needs

Opensource RMMs can be sufficient for a startup or small organization with, say, about 50-100 endpoints. 

But enterprise organizations with thousands of endpoints require unlimited automation, integrations and customization that only a commercial RMM can support.

3. Cost of acquisition, implementation and maintenance

What are your business requirements? Would acquiring an open-source solution meet the requirements? If not, what is the cost of customizing the open-source solution? How does this compare with the cost of buying an RMM?

If the cost of open-source customization exceeds that of a commercial solution, acquiring the commercial RMM is cost-effective. 

If you have an experienced team of developers that can customize the solution for efficiency, security and continuous improvement, then open-source RMM can be feasible.

Watch out for the weak point

One of the critical things that can render open source RMM insignificant is weak security. Data privacy and confidentiality remain a critical consideration, especially with the rise in cyber security threats. And if an RMM offers no proof of security, how safe is the data that it’s going to manage?

Even as we celebrate the convenience of open source software, pay attention to the security threshold. Go for open source RMM solutions that can guarantee optimal security, powered by a community that is conscious about cybersecurity and data loss prevention best practices.
