NetworkTuna — Free Download. Network activity detection

NetworkTuna is a Windows security tool that detects suspicious activity around your PC, monitors router changes, and shows the evidence behind its findings. It records incoming connection attempts, including those blocked without a notice, and lets you review connections blocked by NetworkTuna or your Windows firewall. The program helps you decide when apps connect, keeps a long-term traffic history, shows connections as they happen, and identifies which apps use your network, where they are installed, and who published them. It works alongside Microsoft Defender Firewall or your preferred Windows firewall. Available as a public beta for Windows 10 and 11 on x64 and ARM64, with a 14-day trial and a one-time purchase.

Suspicious connection attempt detection. The program examines network traffic for port scans and repeated attempts from nearby devices to reach services running on your computer. It records these events and presents the evidence behind each finding, so you can review what happened and determine whether the activity warrants further investigation.
Router change monitoring. Optional router checks watch for modifications to management access and security keys, whether you connect through Wi-Fi or a network cable. The program warns when SSH access becomes available after being closed or when a remembered SSH key changes, giving you awareness of alterations to your router configuration.
Incoming connection attempt logging. The software records attempts to reach your PC, including those that your firewall blocks without generating a notice. This provides a record of external contacts that might otherwise remain invisible and helps you understand what is targeting your system.
Blocked activity review. You can inspect connections blocked by NetworkTuna or by your Windows firewall. The program presents blocked activity overviews and details, including attempts to reach your PC that were blocked silently, so you can evaluate what your defenses have stopped.
Application connection control. The program lets you choose which applications may connect, which should stay offline, and which can connect for a limited time. A Windows notification appears when an app needs your permission, keeping you informed about network access requests.
Long-term traffic history. The software tracks how much data each application sends and receives over hours, days, or months. You can look back at an app's connections and where they went, building a historical record of network behavior on your system.
Real-time connection view. You can see which applications are connected right now, how much data they are using, and where they connect. Recently closed connections remain visible, so you can review activity that has just ended.
Application inventory. The program identifies which applications use your network, where they are installed, and who published them. You can check whether each application is allowed, blocked, or set to ask, maintaining an overview of network-capable software on your PC.
Protection overview. An overview screen displays protection checks and recent activity, available in light and dark modes. This gives you a summary of the current security state and recent network events in one location.
Security alert evidence. When the program raises a security alert, it provides the supporting evidence behind the finding. This includes details about the detected activity, allowing you to assess the alert rather than relying on a notification alone.
Firewall complement. NetworkTuna is designed to work alongside Microsoft Defender Firewall or your preferred Windows firewall. It adds suspicious activity detection, optional router monitoring, and investigation tools without replacing the firewall already protecting your PC.
Local data storage. Your network history stays on your PC. The program does not require sending your network data to external servers, keeping the recorded information on your local system.

NetworkTuna is developed as a Windows security application focused on detecting suspicious network activity and providing investigation tools for home users. The program entered its first public beta, marking a milestone in its development, and is available for Windows 10 and 11 on x64 and ARM64 architectures. The development team behind NetworkTuna built the application to complement existing Windows firewall protection rather than replace it. The software is distributed as a public beta with a 14-day trial and a one-time purchase for continued use, without a subscription model.
