Security Tools

ARP Scan

The Address Resolution Protocol (ARP) is the method for finding a host's hardware address when only its IP address is known. This tool  allows host detection and fingerprinting using the ARP protocol.

IKE Scan

Ike-scan was developed by NTA's Technical Director Roy Hills and released in 2003 under the GNU General Public Licence (GPL). Ike-scan exploits transport characteristics in the Internet Key Exchange (IKE) service, the mechanism used by VPNs to establish a connection between a server and a remote client. It scans IP addresses for VPN servers by sending a specially crafted IKE packet to each host within a network.

TCP Scan
tcp-scan is a bandwidth-optimised half-open TCP port scanner which gives full control over the outgoing bandwidth and the outgoing TCP packet flags and options. It also displays the flags and options on received packets, which allows it to be used for stack fingerprinting.


ipgen is a simple command-line tool which converts IP network specifications to a list of IP host addresses, which can be used as input for other scanning and testing tools.

To continually give back to our partners we have structured a list of security tips devised from the results, feedback and analysis of our previous years testing coupled with some handy "good to know" general tips for security.
