Max IEC Gateway
Modbus TCP/RTU to IEC 60870-5-104/101 gateway with web dashboard
Max IEC Gateway connects Modbus devices to SCADA systems. It reads meters, inverters, PLCs and drives over Modbus TCP, Modbus RTU (RS-485/RS-232) or RTU over TCP, and serves the data as an IEC 60870-5-104 or IEC 60870-5-101 controlled station (slave). Map registers to IEC points in a web dashboard: single and double points (also from register bits), measured values, step positions, bitstrings and energy counters, with any byte order, scaling, deadbands and time tags. ... -

Shadow Network Fingerprinting Engine
SNF is a 100% offline, air-gap passive network intelligence engine
# SNF — Shadow Network Fingerprinting Engine 100% offline. Air-gap-native. Written entirely in Rust. SNF captures raw packets, reconstructs TCP/UDP flows, and runs them through 14 deterministic protocol analyzers. It detects C2 beacons, DGA domains, DNS tunnels, lateral movement, data exfiltration, and full ICS/SCADA protocol abuse across Modbus, S7comm, EtherNet/IP, PROFINET, and DNP3. Every run produces structured NDJSON with a determinism guarantee — same PCAP, same config, same version, SHA-256 identical output every time. ... -

Kindling
eBPF-based Cloud Native Monitoring Tool
Kindling is an eBPF-based cloud-native monitoring tool, which aims to help users understand the app behavior from kernel to code stack. With trace profiling, we hope the user can understand the application's behavior easily and find the root cause in seconds. Besides trace profiling, Kindling provides an easy way to get an overview of network flows in the Kubernetes environment and many built-in network monitor dashboards like TCP retransmit, DNS, throughput, and TPS. ... -

Netstack
IPv4 and IPv6 userland network stack
...The stack implements TCP, UDP, ICMP, neighbor discovery, and common socket behaviors, including options like MSS/MTU handling and congestion control hooks. Because it’s written in a memory-safe language with extensive unit tests, it is easier to audit and evolve than many kernel-bound alternatives. netstack is frequently used as the networking core for systems that need strict isolation guarantees and deterministic behavior without privileged code. -

lua-resty-waf
High-performance WAF built on the OpenResty stack
lua-resty-waf is a web application firewall implemented in Lua for OpenResty/NGINX, designed to run inline at the edge with low overhead. It inspects requests and responses during NGINX phases, applying rule logic and anomaly scoring to detect patterns like SQL injection, cross-site scripting, and protocol abuse. Rules are organized into policies with configurable actions—block, log, or allow—and can leverage shared dictionaries for counters, rate limits, and caching decisions. Because it... -

Network Connection Test
Server and Client applications for testing network connectivity.
“Network Connection Test“ has two applications, one Server and one Client. The Server application listens on a TCP and/or UDP port and the Client application connects to these ports. Both applications display logs when the client connects and the data is being sent and received. This is a useful tool when configuring network routers or firewalls. The source code is a demonstration of sockets and multithreading programming using C#. -
