Arachni is an open source high performance Web Application Security Scanner Framework written in Ruby framework aimed towards helping penetration testers and administrators evaluate the security of web applications. Arachni is smart, it trains itself by learning from the HTTP responses it receives during the audit process and is able to perform meta-analysis using a number of factors in order to correctly assess the trustworthiness of results and intelligently identify false-positives. This version includes lots of features, including.

4. Accuracy improvements and bugfixes for the XSS, SQL Injection and Path Traversal modules
5. New report formats (JSON, Marshal, YAML)

2. BeepNotify — Beeps when the scan finishes.

4. EmailNotify — Sends a notification (and optionally a report) over SMTP at the end of the scan.
