Free web-based Security Tools from Infosec Island

FREE Tools Collection

Welcome to our collection of Free Tools for you to use. Some of these were developed by Infosec Island as simple checks for common security problems, others have been graciously donated by our Tradwinds © Partners, and others are just so cool we want you to have them!


Island Tools

A collection of free, web-based tools for checking on some basic security issues. Some of these tools are useful in identifying vulnerabilities within your network infrastructure as a result of 3rd party vendors.


Domain Hostname Enumerator

This tool first checks a domain's DNS servers for Anonymous Zone Transfer (AXFR), then scours the Internet looking for cached hostnames that may belong to the queried domain. Complete with WHOIS lookups on all discovered hostnames.

Email Address Enumerator

This tool scours the Internet searching for email addresses associated with the queried domain name. Attackers can leverage known email addresses for your domain to craft brute-force attacks and social engineering scams.

DNS Server Configuration Checker

This tool provides a basic check against a given domain name to determine if the DNS servers are vulnerable to Anonymous Zone Transfer (AXFR) or Recursion -- both of which have been shown to present security risks.
