What is network monitoring?
Network monitoring continuously tracks a network’s health, performance, and security using specialised software. It is part of network operations handled by IT departments or dedicated network administrators.
The primary goal is to ensure that all network components, including servers, business broadband routers, switches, and devices, operate efficiently and securely.
Key features of network monitoring
Key features of network monitoring tools include:
- Real-time tracking: Provides up-to-the-minute insights into data flow, bandwidth usage, and device performance, ensuring continuous visibility into your network’s status.
- Instant alerts: Real-time alerts for outages, slowdowns, or security breaches allow administrators to respond quickly and minimise downtime.
- Performance metrics: Tracks bandwidth usage, packet loss, business broadband speed and latency. Network monitoring helps identify bottlenecks and improve overall network efficiency.
- Traffic analysis: Examines data flow to spot high-traffic patterns or suspicious activity. It covers essential cybersecurity and performance monitoring.
Types of network monitoring tools
Network monitoring tools come in various forms, each designed to address different aspects of network oversight.
Some focus on overall network performance, while others target specific hardware, software, or traffic-related metrics. Network monitoring software solutions provide a unique combination of these tools to target a specific market niche.
To help illustrate the range of network monitoring tools, here is a table with the different types of tools with examples of providers that offer them:

Pros and cons of network monitoring for businesses
Network monitoring is a valuable tool for businesses of all sizes, providing essential insights into network performance and security.
However, its utility may vary depending on a business’s reliance on digital services or IT infrastructure. For businesses with minimal network requirements, implementing monitoring tools may seem unnecessary or lead to an overload of non-critical alerts if not properly managed.
As with any technology, network monitoring has benefits and challenges. Understanding these can help businesses decide whether the investment is right for them. Let’s explore the key advantages and potential drawbacks of network monitoring tools:
Benefits of network monitoring for businesses
- Minimises downtime: Real-time alerts instantly notify businesses of network issues, allowing them to resolve problems quickly, reducing costly downtime and ensuring operational continuity.
- Enhances security: Network monitoring tools help detect abnormal traffic patterns or unauthorised access, providing early warnings of potential cybersecurity threats and enhancing overall security.
- Improves performance: By tracking bandwidth usage and traffic flows, businesses can optimise network performance, reduce congestion, and ensure critical applications get the necessary resources.
- Reduces troubleshooting time: Automatic diagnostics help pinpoint the source of issues, reducing the time spent on troubleshooting and leading to faster resolution.
- Compliance support: Many industries, such as healthcare or finance, require businesses to meet strict data protection and network performance standards. Network monitoring tools assist by providing logs and reports for cybersecurity compliance.
Drawbacks of network monitoring for businesses
- Complexity: Implementing network monitoring tools can be complex and time-consuming, especially for businesses without dedicated IT staff. Proper configuration is critical to avoid unnecessary alerts and misinterpretations.
- Cost: High-quality network monitoring solutions, especially for small businesses broadband customers and startups, can be expensive. In addition to software costs, there may be ongoing fees for scaling or additional features.
- Alert overload: Network monitoring tools can generate too many alerts without proper configuration, overwhelming IT teams with notifications about minor issues or false positives.
- Requires ongoing management: To stay effective, monitoring tools need regular updates and fine-tuning, which can require ongoing attention from IT staff to adapt to network changes or new security threats.
Popular network monitoring software for businesses
Hundreds of network monitoring software are available, ranging from open-source solutions to enterprise-grade, commercial products.
It is common for comparison and review websites to list 30 or more solutions, differentiating them by paid, free, open-source and complex and simple products.

Choosing the right business network monitoring software
Picking the right network monitoring software involves understanding what your business needs. Here are the main factors that will affect your choice:
Business Size
Small businesses benefit from simple, budget-friendly tools like Paessler PRTG and Nagios, while large companies benefit from comprehensive solutions for handling complex networks with multiple sites and devices, such as Zabbix.
Network complexity
More complex network setups, such as SD-WAN for multi-premise sites or 5G private networks for high-bandwidth IoT devices, demand advanced tools to monitor numerous devices, applications, and cloud services.
Budget
Do a cost-benefit analysis. Open-source tools are cheaper but may require more setup and won’t have the same level of support as commercial tools with advanced features and 24/7 assistance.
Integration
It’s important to consider how network monitoring integrates with other tools that manage your network or consume bandwidth to avoid performance issues. Examples of software that can integrate or, in some cases, cause conflicts include:
- Cybersecurity software: Network monitoring can complement firewalls or intrusion detection systems by providing additional insights into traffic patterns, but overlapping scans or traffic analysis can cause redundancy.
- VoIP telephony: VoIP heavily relies on network bandwidth, and monitoring tools help ensure call quality by prioritising traffic. Inadequate integration or configuration could lead to poor call quality or dropped calls during high traffic.
- Cloud-based services: Cloud applications such as project management or supply chain management software can consume significant bandwidth, and traffic analysis can help measure any performance issues.
Implementing network monitoring in your business
Implementing network monitoring requires a few straightforward steps to ensure your system is appropriately set up and monitored effectively.
- Evaluate your network: Identify key devices, traffic, and potential points of failure. Remember to take into account VPNs, Zero Trust Network Access, business dongles, and other atypical network protocols and devices.
- Choose the right software: Select based on your network’s size, complexity, and budget.
- Set up monitoring protocols: Define which metrics to track and set alert thresholds.
- Test and fine-tune: Ensure the system is catching critical issues without over-alerting.
- Train your team: Ensure staff can effectively use the tool for monitoring and troubleshooting.
This process may need adjustments based on the complexity of your solution, but it offers a general idea of the implementation.
Note: Business broadband providers don’t offer network monitoring tools, so you must obtain them from third-party providers.
Best practices for network monitoring
Finally, here are some pro tips for you to get the most out of your business network monitoring tools, especially if you are a small business with limited expertise:
- Set clear alert thresholds: Avoid overwhelming your team with unnecessary alerts by fine-tuning thresholds for critical issues only.
- Review and update regularly: As your network evolves, adjust what you monitor and ensure new devices or services are included.
- Document incidents: Keep detailed logs of issues and resolutions to improve processes and facilitate future troubleshooting and compliance.
- Automate when possible: Leverage automation to resolve minor issues and save time for more critical tasks. AI is your friend!
