Syslog, and by extension, syslog servers (click to learn ‘what is a syslog server?'), are programs and protocols that aggregate and transfer diagnostic and monitoring data.
Here is our list of the best free Syslog servers for Windows:
- Paessler PRTG – FREE VERSION – EDITOR'S CHOICE A package of sensors for networks, servers, and applications that provides automated monitoring and also includes a Syslog receiver. The package is free for up to 100 sensors and it is available as a SaaS platform or as a software package for Windows Server.
- ManageEngine EventLog Analyzer – FREE TRIAL This is an excellent SIEM system in its paid edition but it also offers a Free edition that provides a log manager. Runs on Windows Server and Linux.
- Nagios Log Server Free This companion to the free network monitor, Nagios Core offers the collection and filing of log messages from Windows and Linux that includes Syslog. Runs on Windows and Linux.
- Splunk Light This free version of the Splunk system has been deprecated but you can get a 60-day free trial of Splunk Enterprise to process Syslog messages. Runs on Windows, Linux, and macOS.
- The Dude This free network monitoring tool receives, analyses, and stores Syslog messages as well as other data sources. Runs on Windows, macOS., and Linux.
- Kiwi Syslog Server This system collects, and files syslog messages and SNMP traps and also includes a message viewer. The tool runs on Windows.
- TFTPD64 This service is available in 64-bit format and it provides a range of administration utilities, including the viewing and filing of Syslog messages. Runs on Windows.
- Syslog Server This straightforward Syslog manager is no longer available. It was designed for Windows Server.
- Icinga 2 A free system monitoring package that also provides a collector for Syslog messages that can be filtered by severity level. Runs on Linux.
- Visual Syslog Server This lightweight Syslog collector shows arriving messages in its screen and also files them. Runs on Windows.
- 3cDaemon This is a graphical interface tool for Windows that was written to follow the procedures y of the Unix command line syslogd.
Their power comes from the wide range of data that can be collected and, furthermore, the ways in which this data can be analyzed and levied for the sake of network maintenance, system monitoring, and dozens of other diagnostic and troubleshooting purposes!
Generally, the Syslog protocol is supported by a wide variety of devices and thus it's easy for devices and applications to fire off log information to the Syslog server, which stores the information for further analysis. Most notably, Syslog servers are often capable of triggering alerts or sending notifications. This enables an admin in the field to receive time-critical information or to simply gets a heads up of something that may need attention soon.
Thanks to a built-in severity metric, it's easier to know when something can wait and when it can't. SNMP ties heavily into Syslog server functionality and can be used in tandem to poll all the wonderfully wide variety of information that admins are used to snatching up via SNMP.
However, when taken a step further via Syslogging server software, they can take that SNMP data and do a lot more with it – graphical interfaces that aggregate and monitor SNMP data, for example, can massively speed up the assessment of almost any number of critical systems or failure points.
Using these same metrics many Syslog servers can also have automated scripts or events that will trigger and can potentially streamline the process of recovering from, or preventing, downtime or outages. Some Syslog servers require client-based software to manage but many also offer web-based solutions, which can ease management both remotely or from different systems on a network environment.
Most servers are also quite good at data management and will handle some level of archival functionality for saving older logs or records that may not actively be needed at present. Syslog does have a few drawbacks – it's not particularly standardized, meaning that sloppy implementation can cause troubles for Syslog servers, and it also lacks any kind of authentication. In a trusted network environment, this isn't really an issue, but especially nefarious malware or untrusted networks can sow seeds of trouble.
The Best FREE Syslog Server Software & Tools of 2025
Our methodology for selecting free Syslog servers for Windows
We reviewed various free Syslog servers for Windows and analyzed the options based on the following criteria:
- Compatibility across various Windows environments
- Integrations into other log collection platforms
- Graphical interpretation of data, such as charts and graphs
- A free trial period, a demo, or a money-back guarantee for no-risk assessment
- Free versus premium versions
Below is a list of software that performs these functions and more, as well as the compatible operating systems and, quite importantly, whether it supports some form of alert (alarms, pop-ups, etc.) and/or notifications (email, txt, etc.)
1. Paessler PRTG – FREE VERSION
Paessler PRTG has some Syslog ability then added via a sensor to the PRTG monitoring suite. Primarily focuses on SNMP and Syslog protocol data and has a good amount of analysis ability due to the built-in capability PRTG already has for general monitoring and management.

Conclusion
Syslog tracking via a powerful Syslog server can save any network administrator an obscene amount of time and effort.
Every bit of data, whether SNMP or Syslog, that can be requested, aggregated, and analyzed is another potential piece of a puzzle that can trigger alerts or notifications and quickly bring human attention to the problem as soon as possible, or even fire off predefined scripts or programs to alleviate, or at least slow down, oncoming issues.
The flexibility of these programs are a superb way for admins to leverage monitoring to their advantage with the goal of maximum uptime and stability.
Much of this information can be seen on any one system or device, but even a small network with a few dozen devices would be totally unreasonable to monitor one by one – having it centralized, automated, and closely monitored is invaluable!
