How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
Findomain is a subdomain discovery tool and DNS resolver used for mapping an organization's external attack surface. It functions as a DNS infrastructure analyzer that searches for registered subdomains associated with a root domain to uncover undocumented infrastructure and services. The project includes an attack surface monitor that tracks changes to subdomains over time, using differential state monitoring to identify newly created or deleted assets. It provides real-time alerting via webhooks when changes in the monitored domain surface are detected. The system performs high-speed DNS r
Subfinder is a passive subdomain enumeration tool and DNS asset discovery utility designed for mapping the external attack surface of a domain. It functions as a passive reconnaissance framework that identifies subdomains by querying curated third-party data sources and APIs without interacting directly with the target infrastructure. The tool utilizes a modular provider interface to integrate various passive sources and employs concurrent request orchestration to manage simultaneous network queries. It includes wildcard DNS filtering to identify and remove catch-all records, ensuring the res
Sn1per is a vulnerability management platform and penetration testing orchestrator designed to automate reconnaissance, vulnerability scanning, and exploit verification. It functions as a dockerized security toolkit that coordinates multiple tools into a unified automated pipeline to identify security flaws across network and web assets. The platform features an attack surface manager for discovering internet-facing assets through OSINT, DNS enumeration, and certificate transparency. It distinguishes itself with an AI-powered security analyzer that uses large language models to summarize scan
This project is an open-source intelligence reconnaissance framework and recursive attack surface mapper. It functions as a containerized security scanner designed to map public-facing infrastructure, perform subdomain enumeration, and automate the gathering of open-source intelligence. The system employs a recursive discovery engine to iteratively explore target infrastructure, utilizing a plugin-based module architecture to extend scanning capabilities. It integrates third-party APIs for data enrichment and applies YARA rules across discovered assets to identify specific vulnerability patte
An advanced subdomain discovery service with fast, powerful and easy to use API and DNS history.
