• Active connection monitor. Shows all established TCP and UDP connections on the system. Includes local and remote IP addresses, ports, connection status, and associated process. The information is updated in real time and can be filtered by protocol or status.
• List of open ports. Identifies all listening ports on the computer. Details the process using each port, including name, ID, and executable path. Allows detection of unauthorized services or potential vulnerabilities.
• Network traffic statistics. Records the volume of data transmitted and received by each network interface. Provides per‑adapter metrics, including bytes sent/received and transfer speed. Data can be exported for later analysis.
• Name resolution. Converts IP addresses into hostnames using reverse DNS queries. Supports IPv4 and IPv6 with local cache to speed up repeated lookups. Option to disable resolution and work only with IP addresses.
• Process information. Associates each connection with the corresponding process on the system. Shows executable name, process ID, full path, and owning user. Allows terminating processes directly from the interface.
• Advanced filtering. Allows creating custom rules to show only specific connections. Filters by IP, port, connection status, or process name. Filters can be saved and applied automatically when the program starts.
• Historical logging. Stores previous connection data for comparison and analysis. Configurable sampling interval and log retention. Export logs in CSV or TXT format for external processing.
• Configurable alerts. Notifies when connections matching predefined criteria are detected. Supports visual, sound, or email notifications. Customizable thresholds for unusual network traffic.
• WHOIS integration. Queries domain registration information for remote IP addresses. Direct access to ISP data and network ranges. No additional configuration required for basic queries.
• Bandwidth monitor. Real‑time graphs of network usage by process or interface. Displays traffic spikes and average consumption. Automatic axis scaling to adapt to different value ranges.
• Report export. Generates documents with analysis results in various formats. Includes options to customize report content and layout. Scheduling of automatic exports at regular intervals.
• Customizable interface. Allows reorganising columns, changing fonts, and adjusting colour schemes. Compact view for continuous monitoring without wasting space. Multiple configuration profiles for different usage scenarios.

NetStat Agent was initially developed in 2012 by a team specialising in network tools. The core is written in C++ with additional C# components for the graphical interface. The application has received regular updates to maintain compatibility with new versions of Windows and network protocols. The developers continue to add features based on feedback from professional users.
