1 Factor 1: Scope

The first factor to consider is the scope of your network discovery. Do you want to scan your entire network, or only a specific segment or subnet? Do you want to discover physical devices, virtual machines, cloud resources, or all of them? Do you want to collect basic information, such as IP addresses and MAC addresses, or more detailed data, such as operating systems, applications, protocols, and ports? Depending on your scope, you will need different types of tools, such as ping sweepers, SNMP scanners, port scanners, or network analyzers.

Network Identify tool has a key role in a big firm with mini branches and multiple division. If WAN is possible but still the basic information collections from all IP addresses is not possible and you need to check one by one and it's not efficient. And in such cases by using a tool to collect information from all networks will play a key role in the development of organisation.

Choosing the right network discovery tools is like picking the best detective for a digital mystery. Consider these key factors: Scope: Can it map the entire network or just parts of it? Compatibility: Does it play well with all your devices and systems? Usability: Is it user-friendly, or do you need a tech degree to use it? Security: Does it safeguard your network's secrets while exploring? Reliability: Can you trust it to consistently work without failing? Testing: Give it a trial run to see if it meets your needs and catches issues. Selecting the perfect tool involves matching it to your network's size, ensuring it works with your tech, finding it easy to use, confirming it's secure, reliable, and testing it firsthand.

To choose a reliable network discovery tool, consider its reputation and industry usage. Check user reviews and ratings for real-world insights. Ensure it has necessary features like device discovery, IP address management, and network topology mapping. Good support and regular updates from the provider are crucial. Tools like SolarWinds Network Performance Monitor and ManageEngine OpManager are popular. Most reliable tools offer a trial period to test if they meet your needs. Remember, the best tool depends on your specific needs and network environment.

2 Factor 2: Compatibility

The second factor to consider is the compatibility of your network discovery tools with your network devices and systems. You need to make sure that the tools can communicate with your devices using the appropriate protocols and credentials, and that they can support the features and functions of your devices. For example, if you want to discover SNMP-enabled devices, you need a tool that can use the correct SNMP version and community string. If you want to discover Windows devices, you need a tool that can use WMI or PowerShell. If you want to discover Linux devices, you need a tool that can use SSH or Telnet.

3 Factor 3: Usability

The third factor to consider is the usability of your network discovery tools. You need to make sure that the tools are easy to install, configure, and run, and that they provide clear and comprehensive results. You also need to make sure that the tools are scalable and flexible, and that they can handle large and complex networks. You should look for tools that have user-friendly interfaces, intuitive dashboards, and customizable reports. You should also look for tools that have automation and scheduling features, and that can integrate with other network management tools.

6 Factor 6: Testing

The sixth factor to consider is the testing of your network discovery tools. You need to make sure that the tools work as expected, and that they do not cause any negative impact on your network or devices. You should test your tools in a controlled and isolated environment, such as a lab or a sandbox, and compare their results with other sources of information, such as your network documentation or inventory. You should also test your tools in different scenarios, such as normal, peak, or failure conditions, and monitor their performance and behavior.

Uma coisa que encontro útil quando se pensa sobre testar sistemas em geral, é garantir um ótimo ambiente de provas. No caso de ferramentas para internet, procure tentar simular o ambiente produtivo que sua ferramenta vai encontrar. Existem softwares locais para fazer isso, existem ferramentas que podem auxiliar em um ambiente de homologa??o em nuvem. Independente da ferramenta, teste em um ambiente controlado.
