# Log analyzer tools for IIS web server logs

IIS webserver logs each and every access into a log file. To better understand
the data from the log, little help is needed in the form of a log analyzer. Log
analyzer is a software that allows you to visualize log data in a human-readable
form and most importantly, it allows you to filter the logs. You can filter out
unwanted data, such as bot visits and brute force attacks which are quite
common.

Here are the two most used log analyzers for IIS webserver:

1. [WebLog Expert](https://www.weblogexpert.com/)
2. [Log Parser Studio](https://techcommunity.microsoft.com/t5/exchange-team-blog/log-parser-studio-2-0-is-now-available/ba-p/593266)
