Arachni Performance


Arachni's HTTP stack has the time-proven cURL library at its core and utilizes asynchronous requests in order to squeeze out every little bit from your available resources.In addition, the High Performance Grid allows you to combine the resources of multiple nodes for lightning fast scans.

Arachni Intelligence


In order to compensate for the widely heterogeneous environment of the WWW Arachni utilizes a combination of widely deployed techniques (taint-analysis, fuzzing, differential analysis, timing/delay attacks) along with novel technologies (rDiff analysis, modular meta-analysis) developed specifically for the framework.

Arachni Automation


Arachni is a fully automated system which tries to enforce the fire and forget principle. As soon as a scan is started it will not bother you for anything nor require further user interaction.Upon completion, you will be able to export the scan results to several different formats (HTML, Plain Text, XML, etc.).

Arachni Flexibility


The system allows for multiple deployment options ranging from a Ruby library for highly customized scripted scans, to a simple single-user single-scan command line interface, to a multi-user multiple/parallel-scan distributed deployment, to a global High Performance Grid deployment for lightning fast scans.
