The DMCA system processes DMCA notification emails from an MTA, quarantines the appropriate user (with administrator approval for each case), and unquarantines users who click a button agreeing with administrator-customizable text. The system is also capable to referring users with multiple strikes. See the README for more information.

The shutoffs console lets network administrators quickly and easily disconnect hosts from the network. It can also be configured to notify the owner of the host by email (or other methods written in PHP). With each host shut off, the system generates a link that can be used in the future to unblock the host.
Other features include setting a date in the future when a host will automatically be shut off and setting an expiration date when a host will automatically be let back on.
To install it, you'll probably need to write some PHP code to integrate it into your particular network. See the README for more information.

Secscan is a system that scans your network for security vulnerabilities with Nessus and PVS and presents results in a relatively easy to view manner. See the README for more information.
