    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.

    BerserkArch

    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.

    GUN

    GUN

    Cybersecurity protocol for syncing decentralized graph data

    GUN is a small, easy, and fast data sync and storage system that runs everywhere JavaScript does. The aim of GUN is to let you focus on the data that needs to be stored, loaded, and shared in your app without worrying about servers, network calls, databases, or tracking offline changes or concurrency conflicts. This lets you build cool apps fast. When a browser peer asks for data, it'll merge the reply with its own data using a CRDT, then cache the result. GUN is fully decentralized (peer-to-peer or multi-master), meaning that changes are not controlled by a centralized server. A server can be just another peer in the network, one that may have more reliable resources than a browser. You save data on one machine, and it will sync it to other peers without needing a complex consensus protocol. It just works. GUN can be used in both browsers and servers. We have made it easy to install in many different environments.

    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!!!

    Open-source security framework for devs and product teams

    tirreno is an open-source security framework. tirreno [tir.ˈrɛ.no] helps understand, monitor, and protect your product from threats, fraud, and abuse. While classic cybersecurity focuses on infrastructure and network perimeter, most breaches occur through compromised accounts and application logic abuse that bypasses firewalls, SIEM, WAFs, and other defenses. tirreno detects threats where they actually happen: inside your product. tirreno is a few-dependency, "low-tech" PHP/PostgreSQL application. After a straightforward five-minute installation, you can ingest events through API calls and immediately access a real-time threat dashboard.
