    SafeLine

    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.

    Stegcore

    Stegcore

    A cross-platform crypto-steganography toolkit

    Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants.

    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!!!
