How Does an IT Network Assessment Work?

Posted by Jordan Weber on Thu, Feb, 20, 2020 @ 13:02 PM

A network assessment is a common tool used by IT departments and managed IT providers like Sagiss. In short, it is a program that catalogs every device and piece of software connected to a particular IT network. 

Today we explain in detail how it works, why we use it, and what to expect of the process.



In addition to its use as a diagnostic tool for troubleshooting, network assessments are also used to connect support providers with potential new clients. Many managed service providers, including Sagiss, offer complimentary network assessments to small businesses. This an excellent way of cataloging every device that requires support and ensuring the business owner has complete information about the state of their IT infrastructure.

That said, the assessment is a fairly technical process that may seem confusing or ambiguous to most people. Some business owners might request an assessment without understanding how the process works or what information is retrieved. Therefore, we’ve assembled this article as a guide for learning more about IT network assessments. This article uses the Sagiss Network Assessment as an example to review how the process works.

Why Run A Network Assessment?

Simply put, a network assessment is an exhaustive inventory of all the components on your network. Every workstation, server, switch, router, and program running on your network carries some form of unique identifier. The assessment program sniffs these out and builds a useful diagram of your IT infrastructure.

Network assessments can also diagnose the state of the network and its operational status. IT administrators can pull all sorts of information about a given workstation, server, or program. This includes serial numbers, recent updates, IP addresses, user activity, memory, available storage, and a great deal more.

How Does A Network Assessment Work?

The assessment program compiles data about your network infrastructure and then organizes that data into meaningful feedback. The Sagiss Network Assessment breaks down the information into two categories, Network Overview and Security Status.

Network Overview

This is a general overview of the machines and apps connected to your company’s IT network. It includes:

  • Operating Systems – A complete breakdown of every type of OS currently running on your network
  • Updates – Which workstations and servers are missing critical updates
  • Anti-Spyware & Anti-Virus – Checks whether critical security programs are active on the network
  • Login History – Have any users been inactive more than 30 days?
  • Network Diagram – A visual hierarchy of every piece of hardware that makes up your network
  • Software – Are software licenses all up to date? Are any workstations missing standard software?

The assessment generally includes a summary as well as an exhaustive list of each data point. If you are a business owner who has requested a network assessment, ask the provider to review these results with you. A qualified support provider should be able to interpret the results into actionable steps.

Security Status

A network assessment should also provide information about the state of your network security. The assessment sniffs out common security issues and categorizes them according to priority. A few of these categories include:

  • External Scans – Are any ports on your network open to the general internet?
  • Content Filtering – Does the network automatically filter email and web content?
  • Account Lockouts – Incorrect password attempts should lock out user accounts.
  • Password Policy – Are users required to change passwords? What are your password requirements?
  • Dark Web Research – Have user credentials associated with your company been published on the dark web?
  • Rights Management – Users should only access what they need to perform their work.

The assessment also detects each application in use on your network, the version number of the software, and how many PCs are using it. 

The documented results of a network assessment should be yours to keep once the process is complete. Work with providers that can give you assurances your confidential data won’t be seen by a third party.

The results themselves are typically available in various forms. At Sagiss we provide the overview with a short slide deck, and the full results in a Word or Excel sheet.

Finally, before you give anyone access to your network, make sure they will sit down with you to review the results.
