Full Stack Computer Scanner
Scans the entire computer device "stack" (hardware, software, comms)
The FULL STACK COMPUTER SCANNER is a proprietary FREEWARE Windows system diagnostics tool designed to help users assess a computer’s overall security posture. The application performs read-only analysis across 50 key system sectors, including hardware, firmware, boot components, operating system configuration, installed software, browser extensions, and network-related indicators. The scanner does not remove, block, quarantine, or modify anything. This is the initial 2026 public release of a transparency-first diagnostic tool focused on visibility, awareness, and education, rather than automated remediation. The project includes the application, full documentation, architecture disclosure, and detailed explanations of each scan area. License: Proprietary Freeware (not open source). See Freeware License 2026.txt for full terms. Thank you for your visit. Your digital safety is our digital safety. KCJ Tech Solutions computerscannerapp@gmail.com -

BerserkArch
A bleeding-edge, security-centric Arch-based Linux distribution.
BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners. -

SafeLine
Serve as a reverse proxy to protect your web services from attacks
SafeLine is a self-hosted WAF(Web Application Firewall) to protect your web apps from attacks and exploits. A web application firewall helps protect web apps by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web apps from attacks such as SQL injection, XSS, code injection, os command injection, CRLF injection, LDAP injection, XPath injection, RCE, XXE, SSRF, path traversal, backdoor, brute force, HTTP-flood, bot abuse, among others. By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server. A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application. -

ODS3 Virtual Machine Challenge
Virtual Machine Image To Test Penetration Skills
The ODS3 Virtual Machine Challenge are downloadable images that can be run as VMWare or VirtualBox instances. The Idea behind the challenge is to test and exercise web application penetration testing in a controlled environment. These images are great for cyber security students, penetration testers and hobbyist. Care should be taken if installed on an Internet access host as the application are purposely vulnerable to attack and exploitation. -

Network Enumeration Tool
Network Enumeration Tool for Host Exploration and Recon
N-ETHER (Network Enumeration Tool for Host Exploration and Reconnaissance) is a robust and highly automated Python script designed to streamline the critical initial phases of network security auditing and penetration testing. It’s core purpose is to perform fast, comprehensive, and consistent host and port discovery across single targets or large lists of IP addresses. N-ETHER functions as an intelligent, opinionated wrapper around the powerful nmap tool, bundling best-practice scanning techniques—including service versioning, NSE scripting, and intelligent port selection—into a single, easy-to-use utility. This significantly reduces auditor workload and potential for human error compared to manually executing multiple complex nmap commands. Read the README!!! -
