This software helps you analyze network packets with more detail than usual firewalls. It looks not just at where a packet comes from or goes, but what data it carries inside. This makes it useful if you want to see what's happening in your network, such as spotting unusual activity or understanding data flows.
The engine is built in C++. It uses methods that process many tasks at once. This allows it to check packets quickly and handle complex network traffic.
Common uses include:
- Looking inside network data to find specific information
- Detecting network behaviors not visible with basic tools
- Improving network security by identifying suspicious contents
- Helping troubleshoot network problems by showing detailed packet info
You won’t need to know programming to use this tool.
Before you start, make sure your computer can run the software smoothly. Here’s what you need:
- Windows 10 or later (64-bit recommended)
- Minimum 4 GB RAM
- At least 200 MB free disk space
- Internet connection to download and update software
- Administrator privileges to install and run network monitoring features
The program works on regular home or work computers without special hardware.

Follow the on-screen instructions:
- Accept the license agreement.
- Choose where to install (leave the default unless you want a specific location).
- Let the installer copy files and set up the program.
After installation, find DPI-Engine in your Start Menu or on your Desktop.
Double-click the icon to open the program.
You may need to give the program permission to access the network.
Once running, DPI-Engine will begin analyzing packets passing through your network.
The application features a simple interface that shows network packets in real-time.
- The main window displays a list of packets with source and destination addresses.
- You can select a packet to view detailed content inside.
- The tool highlights important data, such as domain names or hidden content.
- You can set filters to focus on specific types of packets.
- The engine supports inspection of encrypted traffic using the SNI field (Server Name Indication) without decrypting full content.
Basic operations include:
- Start and stop packet capture.
- Apply filters by IP, protocol, or keyword.
- Export captured data to common file formats for reports.
The program uses multiple threads to ensure smooth performance even with heavy traffic.
If the program does not start or cannot capture packets:
- Check that you have administrator rights.
- Make sure no other program blocks network access.
- Restart your computer and try again.
If you see error messages:
- Read the message carefully.
- Look for messages about missing files or permissions.
- Reinstall the program if needed.
If the packet list is empty:
- Verify your network connection is active.
- Confirm the correct network interface is selected in settings.
- Try restarting the capture process.
For best results:
- Run DPI-Engine on a wired network when possible.
- Keep the program updated for new features and fixes.
- Use filters to reduce clutter and focus on relevant packets.
Packets travel through your network in small data units. Each packet has a header (info about source, destination, type) and a payload (the actual content).
Simple firewalls look only at headers. DPI-Engine looks inside the payload too.
By inspecting payload data, the engine detects:
- Application types like browsers or messaging apps.
- Suspicious patterns or data.
- Network services in use.
This helps identify threats and understand network use beyond basic monitoring.
If you run into problems you cannot solve:
- Visit the repository’s Issues tab on GitHub to check for similar problems and solutions.
- You can post questions or report bugs there.
- Look for any updates or notes from the developer.
DPI-Engine works locally on your own computer and network.
- Your data does not leave your machine unless you choose to share export files.
- The program does not send data to external servers.
- It requires network permissions only to inspect traffic passing through your PC.
Use DPI-Engine responsibly on networks where you have permission to monitor traffic.
