Best tool to find subdomains

INTRODUCTION

Subfinder is an open-source tool used for subdomain enumeration, which means it helps to identify subdomains for a particular domain name. Subdomains are the domains that are part of a larger domain name and are separated by a dot. For example, in the domain name “blog.skullcandy.com”, “blog” is the subdomain.

Subdomain enumeration is important for various reasons, particularly in the context of cybersecurity. Attackers often use subdomains to launch attacks, such as phishing and malware attacks. By identifying all subdomains associated with a domain, security professionals can proactively secure them and prevent potential attacks. Subdomain enumeration can also help in identifying forgotten or abandoned subdomains that could be a security risk, and in identifying new web applications or services hosted on a domain that may not be visible through the main website.
