![Go Report Card](https://goreportcard.com/badge/github.com/elmasy-com/elmasy)

Elmasy *will be* an attack surface analysis tool.
Discover and assess as many as possible publicly accessible assets from a domain name.

This project has 3 goals:

- To provide a website for non-professionals/professionals to check the attack surfaces of publicly accessible assets.
- To provide an API for professionals to work with easily. 
  - The website will use the same API as your service.
- To provide a wide range of libraries for professionals to work with without relying on external services. 
  - The API will use the same libraries as you.

As we grow, we will know more protocols, more services and assess/evaluate as fast as the programming language allows. The project is starts from lower layers (like TCP and UDP), basic services (like web servers) and gathering basic information about the servers (like TLS ciphers).
