When you are the whole IT department, the problem is rarely which tool is best. It is which job to do first, because you cannot do them all in the first week. This article puts a small set of free tools into an order: what to set up on day 1, what can wait until week 1, and what belongs to month 1. It is a selection by licence and project status, not a list of tools we run ourselves. Versions, licences and limits were read on the vendors’ own pages on 10 November 2026. We have not installed or tested these programs for this article (Not tested yet).
The short answer
Day 1: get a scheduled file backup running with SyncBackFree or Personal Backup, and restore one folder to prove it works. Week 1: add outbound firewall rules on the few sensitive PCs and start reading logs, first by hand, then with alerts. Month 1: put a monitoring server and central logs on a small Linux machine, and build a test lab for restores. Seven of the eight tools below state that company use is allowed without payment; the vendor of EventSentry Light does not say so explicitly, so ask before you rely on it at work. Five of the tools have a limit you should know first.

Day 1: backups before anything else
A monitoring dashboard does not help on the day a disk dies. A copy of the files does. So the first job is a scheduled backup of the shared folders and the accountant’s PC, to a second disk or a NAS.
SyncBackFree is the simpler choice on desktops. The vendor, 2BrightSparks, says its free software may be used for “personal, educational, charity, government, and commercial use”. The limits are in the transport: the vendor’s comparison table gives the free edition plain FTP only, while FTPS, SFTP and cloud storage are in the paid editions. It also lists only desktop Windows for the free edition. In practice that means: back up to a local disk or a network share, not over the internet.
Personal Backup covers the gap on servers. The author lists Windows 7, 8, 10 and 11 and “the respective corresponding server versions”. The licence is one sentence: the program “may be used by anyone, in any way, for any purpose, without charge”. It can compress and AES-encrypt the data and has functions to verify and restore a backup. The author also states the limit plainly: it is “not suitable for backing up system data”. It copies files; it does not make a bootable image of a machine.
Finish day 1 by restoring one folder to a different location and opening a file from it. Our guide on how to verify backups lists what else to check. One more day-1 job is outside this article: a way to reach users’ screens. Our free remote support software guide covers that choice.
Week 1: outbound rules and a first look at logs
Microsoft documents the default behaviour of Windows Firewall as blocking incoming traffic unless it is solicited or matches a rule, and allowing all outgoing traffic unless it matches a rule. That default is reasonable for most office PCs. On the two or three machines that hold payroll or banking software, you may want the opposite for outgoing traffic: nothing leaves unless you allowed it. SimpleWall is a free, open-source front end for that job. Its latest stable release is 3.8.7 from August 2025; newer 3.9 builds are marked as pre-releases, so stay on the stable one. Do not roll it out to every PC in week 1. Each new program will ask for a rule, and you are the only person who can answer.
Next, start reading logs. LogExpert follows a growing text log, highlights lines and filters them; it is free and open source and runs only on Windows. For Windows event logs, EventSentry Light sends an alert when a service stops or a disk fills. The vendor’s comparison table shows what the free edition leaves out: remote installation and update is capped at 5 machines, compliance tracking is absent, and e-mail and telephone support are not included. Five is enough for the servers of a small office. It is not a tool for every workstation. The vendor pages we read say nothing explicit about business use of the Light edition, so confirm it with the vendor in writing.
Month 1: central monitoring, central logs and a test lab
By now you know which machines matter. NetXMS watches them from one place. It is licensed under GPL v2 or later, and its licence page says you may run it “at home or in a business, without paying anyone”. The download page adds one condition: the Windows server build “runs up to 250 nodes without a support contract”. No such cap is stated for the Linux packages, so a small Linux VM is the safer home for it.
Graylog Open collects logs from many machines so you can search them in one window. It is free under the Server Side Public License, and the vendor publishes Linux packages and Docker images. It is real infrastructure with its own database and storage, so plan a day for it, not an hour. Our guide to free security and audit log tools explains which logs are worth sending.
Last, a test lab. VirtualBox lets you restore a backup into a virtual machine and try updates before users see them. The base package is GPL v3 and fine for company use. The separate Extension Pack is under a personal and educational licence that excludes use for the benefit of a business, so leave it out.
Who this toolkit fits, and who it does not
- Fits: one admin, roughly 10 to 50 Windows PCs, a few servers, no budget line yet.
- Does not fit: offices that must back up to cloud storage or over the internet (SyncBackFree has neither cloud storage nor encrypted FTP), or that need full system images.
- Does not fit: more than five servers under EventSentry Light, or a Windows-only monitoring server above 250 nodes.
- Does not fit: a company with no Linux skills at all. The Graylog Open downloads are Linux packages and Docker images, and the NetXMS server without the 250-node condition is the Linux one.
When the company grows, the limits move with it. Our free IT department stack for 10, 50 and 250 users shows where each free limit ends.
