Deploy Your Employee Monitoring Software in Minutes
OsMonitor is a high-performance Employee Monitoring Software known for its extreme efficiency. The entire software package is less than 6MB, making it possibly the most lightweight on-premise employee monitoring system on the market. This guide ensures a smooth, 5-minute deployment within your secure local network.
Step 1: Install the Manager Server
The Manager Server is your central hub. It allows you to manage all employee activity monitoring features from a single console. No internet or cloud accounts are needed.
- Run the installer and select "Install OsMonitor Manager".
- Setup is instant thanks to our compact, dependency-free architecture.
Step 2: Note Your Server IP Address
Launch the Manager. Your local IP address will be displayed in the window title bar. You will need this to connect your monitoring agents.
Use the specific IP shown in the Manager title bar to ensure the best connection between the server and clients. In some networks, you might see several IPs. Usually, the first one is correct. If the client cannot connect, try the other candidate IPs listed there.
Why OsMonitor is the Industry Standard
Our employee monitoring software is built on 15+ years of core Windows optimization:
- Ultra-Compact (< 6MB): The entire system is exceptionally small, requiring zero external libraries or heavy frameworks.
- 100% LAN-Based: Total data sovereignty. It functions perfectly as a secure LAN monitor in air-gapped networks with no internet required.
- Tamper-Proof Agent: Employees cannot stop or uninstall the client without an admin password.
Step 3: Deploy the Monitoring Client
Now, install the agent on the target PCs. It runs discreetly in the background.
- Select "Install OsMonitor Client (Agent)" on the target computer.
- Enter the Server IP from Step 2 to connect to your console.
Step 4: Centralized Monitoring
Go back to your Manager Server. The new computer will appear in your console instantly. You can now oversee your entire network in real-time.

Performance & Privacy FAQ
Q: Why is the software package so small (under 6MB)?
We believe in pure performance. OsMonitor is built using Windows kernel-level programming, meaning we don't need heavy 3rd-party libraries. This makes our software extremely fast, stable, and easy to deploy via LAN.
Q: What kind of computer is required to run the Manager Server?
If you are monitoring fewer than 50 computers, any regular Windows 10 or Windows 11 PC can run perfectly as your Manager Server. No databases or complex web services are needed.
If you are monitoring more than 50 computers, you can still use a regular PC just like above. However, for maximum data stability and performance, we recommend using a Windows Server OS and Microsoft SQL Server as your database.
Q: Does it support monitoring in completely offline environments?
Absolutely. This is a Zero-Cloud solution. You don't need to register any accounts with us, and the software never connects to our servers. It is the ideal choice for high-privacy corporate environments.
Q: Is the monitoring agent discreet and tamper-proof?
Yes. The client runs unobtrusively in the background. Thanks to its tiny footprint, it uses negligible CPU resources. Furthermore, it cannot be stopped or removed by unauthorized users, ensuring consistent data collection.
Q: Does it support monitoring multiple user accounts on the same device?
Yes. OsMonitor is designed with a system-wide architecture. You only need to install the client once per device, and it will automatically monitor and control all user profiles—including both Administrator and standard user accounts—as soon as they log in.
Q: Is OsMonitor whitelisted by antivirus software?
Yes, OsMonitor is recognized and whitelisted by major providers like Microsoft Defender and Symantec. For detailed technical specs, please visit our Support Center.
Q: I can't see the employee PC in my list. What should I do?
If the connection isn't established automatically, it is usually a network firewall issue. Please check your environment:
- Port Check: OsMonitor Server uses TCP ports 7211, 7212, and 7213 to communicate. Ensure these ports are not blocked by your router or Windows Firewall.
- Connectivity Test: On the employee's PC, open Command Prompt and run
telnet <Your_Server_IP> 7211to test the connection. You can also try toping <Your_Server_IP>.
