Microsoft Visio is recommended for its widespread popularity and robust capabilities in creating intricate networking diagrams. It stands out with a comprehensive set of design elements specifically tailored for IT professionals, featuring over 70 templates to streamline diagram creation. Visio excels in team collaboration, offering features like instant messaging integration with Skype and Lync, making it a versatile tool for complex designs and collaborative projects. While it comes at a relatively high price, especially in standalone versions, it provides unparalleled flexibility for various network layouts and sizes.

Newer versions of Visio do shine when it comes to team collaboration. Microsoft has gone as far as adding instant messaging into the platform that integrates directly with Skype and Lync. The comments feature is a nice touch, specifically for more complicated designs and when used as a learning tool for other technicians.

Visio was built for IT professionals with hundreds of network-related design elements, and features that can help map out and describe server environments and Active Directory architecture. There are over 70 templates that can be used to jump-start a diagram, allowing for less time drawing and more time getting work done.

Visio symbols also help map out contextual parts of the network. For example, you can easily label certain areas like IoT, helpdesk, HVAC, or datacenter. The design elements are truly flexible for each and every network layout and size.

A big pitfall is the lack of live network discovery and monitoring natively in Microsoft Visio. While the tool is great for planning out networks, it could be made so much better if it featured a probe that functioned similarly to how SolarWinds Network Topology Mapper operates.

Microsoft Baseline Security Analyzer (MBSA) does have a plugin for Visio called Visio Connector, however, MBSA is fairly well depreciated at this point and shouldn’t be used due to its lack of patching and updates.

Who is it recommended for?

Microsoft Visio is suitable for IT professionals and organizations looking for a powerful and widely-recognized networking diagram tool. Its extensive collection of design elements, templates, and features makes it ideal for planning and illustrating server environments, Active Directory architecture, and other network-related structures.
