The Invisible Internet is a privacy-by-design, people-powered network. It is a truly free and anonymizing Internet alternative. Get I2P. The Invisible Internet Project (I2P) is a fully encrypted private network layer. It protects your activity and location. Every day people use the network to connect with people without worry of being tracked or their data being collected. In some cases people rely on the network when they need to be discrete or are doing sensitive work. I2P hides the server from the user and the user from the server. All I2P traffic is internal to the I2P network. Traffic inside I2P does not interact with the Internet directly. It is a layer on top of the Internet. It uses encrypted unidirectional tunnels between you and your peers. No one can see where traffic is coming from, where it is going, or what the contents are. Additionally, I2P offers resistance to pattern recognition and blocking by censors.

GRASSMARLIN provides IP network situational awareness of industrial control systems (ICS) and Supervisory Control and Data Acquisition (SCADA) networks to support network security. Passively map, and visually display, an ICS/SCADA network topology while safely conducting device discovery, accounting, and reporting on these critical cyber-physical systems.

It moves by itself inside networks like virus infection & plagues, it is being written to solve computer virus problem drastically and responsibly. It is legal, free and open for public domain to improve W3 ICT Security.

Server/client suite which provides per-user access control/firewall/QOS. Robust and high speed implementation is secure against MAC/IP spoofing, and can scale to large networks with many clients. Options for additional monitoring and captive portal.

NTPBrowser is a set of classes for viewing NTP server data. The NTPBrowser class itself provides a Swing GUI for "browsing" NTP servers.

Ward is a simple and minimalistic server monitoring tool. Ward supports an adaptive design system. Also, it supports a dark theme. It shows only principal information and can be used, if you want to see nice looking dashboard instead of looking on a bunch of numbers and graphs.
