theHarvester is a tool for gathering subdomain names, e-mail addresses, virtual
hosts, open ports/ banners, and employee names from different public sources
(search engines, pgp key servers).

Is a really simple tool, but very effective for the early stages of a penetration
test or just to know the visibility of your company in the Internet.
