OpenEASD

OpenEASD is an open-source external attack surface discovery (EASD) tool designed for red teamers and defenders, enabling users to rapidly map and assess external surfaces of authorized targets without the expense of commercial solutions. It integrates multiple recon tools—such as `subfinder`, `amass`, and `nmap`—into a single web interface, offering features like scheduling, alerts, and findings tracking, while ensuring results remain local to the user's infrastructure. This self-hosted platform emphasizes transparency and security through careful sourcing of its components and is aimed at small security teams, consultancies, and individual security learners.
