Commercial grade support and services.

Open source flexibility.

Zero Bull.

The OpenNMS Group maintains and supports the OpenNMS® project, the world's first enterprise-grade network management platform developed under the open source model. OpenNMS is an award winning open source network management tool capable of service availability monitoring, performance data collection, event management and notification, as well as automated discovery and integration with many other products.

We are very familiar with OpenNMS since we wrote much of its code.

Free software such as OpenNMS can provide huge advantages to any enterprise. However, as is the case with any open source solution, getting support and customization can be a hassle. The consultants in the OpenNMS Group have worked with both commercial and open source enterprise management tools for over 20 years. We've been involved with OpenNMS since its inception. If you have a question, we've probably seen it before and can save you a considerable amount of time as well as helping you get the most out of OpenNMS.

What makes OpenNMS different?

Unlike many network management solutions currently marketing themselves as "open source", OpenNMS is truly free and open. There are no separate community (open) and enterprise (paid) versions - the only version is the enterprise version. This means that regardless of whether or not you purchase commercial services, upgrades or bug fixes we make to the software are always available for free. It makes us work harder since you can't be locked into paying for OpenNMS just to get upgrades.

If there is no cost for OpenNMS software, how do you make money?

The OpenNMS Group is a services company. We make money by providing support that goes well beyond what you experience with commercial software companies, expert consulting services, training, and custom development, all delivered by people with years of industry experience. Need to learn quickly about OpenNMS? We can help with that. OpenNMS does 90% of what you need? We can develop the remaining 10% - usually at a much lower cost than a commercial solution. We don't sell software - we sell solutions.
