# Best network monitoring tool for small & medium-sized networks By: Visakh 8 minutes Last updated: July 30, 2026 IT teams managing smaller networks are often caught between two worlds: the cost of downtime and the license cost of network monitoring tools. The small and medium-sized business (SMB) market is a broad term that refers to organizations with between 5 and 1,000 employees. Some have a single person taking care of their IT, others have a generalist admin team, while a few employ dedicated teams. Nevertheless, teams managing SMB networks often face the same kind of challenges. ## What are the major challenges faced by smaller IT teams? SMBs have the fastest growth rates among businesses. Their IT systems have to scale up to manage this. They adopt cloud and AI technologies faster, and are expected to maintain enterprise-grade security and uptime. Doing this with a much lower IT budget presents significant challenges for IT teams. **Smaller IT teams:** Unlike enterprises, SMBs rarely have a specialist for every layer of the network. One administrator, or a small generalist team, is often responsible for everything from the router in the server closet to the cloud applications employees rely on every day. **Operational scalability:** As an SMB grows, its network grows with it: more employees, more devices, more locations. IT teams need to scale monitoring and management alongside the business, usually without a matching increase in headcount. **Visibility gaps:** With infrastructure spread across on-premises hardware, cloud services, and remote employees, smaller IT teams often lack a single, unified view of their environment. This makes it harder to catch problems before they reach end users. **Rising IT costs:** Adopting new cloud and AI tools drives up licensing and infrastructure spend, even as budgets stay flat. Without the right monitoring in place, this spending tends to happen reactively, chasing problems instead of preventing them. **Higher MTTR:** Mean time to resolution (MTTR) measures how long it takes to fix an issue once it's identified. With fewer people and less visibility, SMB IT teams often take longer to pinpoint root causes, which drives up MTTR and, with it, downtime. ## What should SMB IT teams look for in a network monitoring tool? Given these challenges, the right network monitoring tool needs to do more than just flag outages. Here's what SMB IT teams should prioritize when evaluating one. **Ease of deployment:** With no dedicated monitoring specialist on staff, a tool that takes weeks to configure isn't realistic. Look for auto-discovery, pre-built templates, and a setup process that gets devices monitored from day one. **Automation:** Automated alerting, ticket creation, and remediation workflows let a small team cover far more ground than manual monitoring allows. Automation is what lets one or two admins do work that would otherwise take a much larger team. **AIOps:** AIOps (Artificial Intelligence for IT Operations) applies machine learning to monitoring data to spot anomalies, correlate related alerts, and flag issues before they cause downtime. For SMB teams already stretched thin, this cuts down on alert fatigue and helps prioritize what actually needs attention. **Unified dashboards and tracking:** A single view across network, server, and cloud performance means IT teams aren't jumping between five different tools to piece together what's going on, and historical tracking makes it easier to spot trends before they turn into outages. This is especially valuable for generalist admins who don't have the bandwidth to become experts in every platform they're responsible for. **Predictable costs:** Licensing that scales unpredictably with usage can blow past an SMB's budget without warning. Flat, per-device, perpetual, or subscription-based pricing makes it easier to plan ahead and avoid surprise bills as the network grows. ## The X-factor: Cloud and application visibility Every point above matters, but the factor that increasingly separates a good SMB monitoring tool from a great one is whether it looks beyond the traditional network. SMBs are adopting cloud infrastructure and SaaS applications faster than larger enterprises, often because it's cheaper than building and maintaining on-premises systems from scratch. This means a growing share of what actually affects an SMB's uptime and user experience now lives outside the traditional network perimeter, in cloud servers, containerized applications, and third-party services. A monitoring tool that only watches routers, switches, and on-premises servers will miss this entirely. If a business-critical SaaS application slows down, or a cloud server's resource usage spikes, a network-only tool has no way to catch it, let alone explain why users are affected. This is why cloud and application visibility has become the deciding factor for many SMBs choosing a monitoring tool today. It's no longer enough to know that the network is up. IT teams need to see how their cloud workloads, applications, and network are performing together, since a slowdown in any one of them can just as easily be mistaken for a problem in another. ## What are the best network monitoring tools for SMB IT teams? ### ManageEngine OpManager ManageEngine OpManager fits the bill for SMB IT teams in more than one way. OpManager automates network monitoring: from discovery, alerting, and remediation. It has some of the lowest prices among network monitoring tools, and offers perpetual licensing. It can also use AIOps to set alerts, forecast performance, and identify the root causes of issues. What makes OpManager stand apart from other network monitoring tools is its flexible add-ons. Add-ons are designed to unlock infrastructure, cloud, and app visibility as required. IT teams can enable just the features they want without paying for expensive tool stacks. This means that SMB IT teams can use OpManager as a network monitoring tool, and add application and cloud monitoring when needed to attain full-stack observability. ### SolarWinds NPM SolarWinds NPM is similar to OpManager in many ways. It's primarily a network monitoring tool with functionalities that can be added on as required. What makes SolarWinds different is the price. After they were acquired by private equity, SolarWinds scrapped perpetual licenses and tripled their prices. This has led to a lot of SMB IT teams switching to ManageEngine OpManager from SolarWinds. ### Paessler PRTG PRTG is a sensor-based network monitoring tool. While many users report that PRTG is easy to configure and use, it's primarily focused on network infrastructure and traffic monitoring. Teams would have to use separate tools for managing configs, apps, and cloud infrastructure. Moreover, the same private equity firm that acquired SolarWinds had acquired PRTG: resulting in higher costs and scrapping perpetual licenses. ### Nagios XI Nagios XI is the commercial edition built on top of the open-source Nagios Core. It adds a web-based interface, automated discovery, and capacity planning to Nagios' plugin ecosystem. It's a capable, well-regarded platform that scales from small deployments to large enterprises. The catch for SMB teams is complexity. Nagios XI still leans on the Linux expertise and configuration work that its open-source roots never fully shed. Reviewers consistently point to a steep learning curve and a dated interface. For a generalist admin already juggling five other responsibilities, that's a lot of setup time to spend before getting real value out of the tool. ### Progress WhatsUp Gold WhatsUp Gold, from Progress Software, covers similar ground to OpManager: network monitoring with optional add-ons for applications, virtual environments, and configuration management. It's reasonably priced and well-liked for its alerting and network mapping. Where it runs into trouble is scale. User reviews note that its automated discovery can slow down once a network grows past a moderate number of devices. Licensing costs also climb quickly once enough add-ons are stacked on for full visibility. For an SMB that expects to keep growing, that's a tool that may need replacing just as it starts to prove itself. ## Why OpManager is the perfect network monitoring tool for SMB IT teams Looking back at the challenges and criteria covered above, OpManager addresses each one directly. SMB IT teams don't have to trade one priority for another. OpManager ships with auto-discovery, classification, and 11,000+ pre-built templates that helps smaller teams to monitor devices without weeks of configuration. AIOps capabilities simplifies alerting and root-cause analysis, helping with visibility gaps and higher MTTR. OpManager still offers perpetual licensing at some of the lowest prices in its category. This matters more than ever now that SolarWinds and PRTG have moved away from perpetual licenses. Add in flexible, pay-for-what-you-use add-ons, and SMB IT teams get predictable costs at every stage, whether they're monitoring just the network or scaling up to cloud and application monitoring. OpManager's add-ons are part of the same platform, not a separate tool or vendor. That gives SMB IT teams the full-stack observability without the cost or complexity of stitching multiple products together. That's the difference between a tool that adds one more thing to manage, and one that gives time back. ## Resources to dig deeper ### Network monitoring tool ManageEngine OpManager is a network monitoring tool that turns the raw telemetry generated by your IT into intelligent insights.
