Reported to me by Craig Norvell: Haystax appears to have some interesting Lisp projects in the works. Combining Lisp, Prolog, RDF (AllegroGraph), and a BBN for insider threat detection solutions.
From their website:
Haystax's predictive models are continuously updated based on the prevailing threat environment making it highly suitable for both detection and continuous evaluation of threats. These unique models go beyond traditional web and business intelligence to enable organizations to achieve contextual real-time situational awareness by fusing all operationally relevant information - private, public, video and live feeds - into consolidated views to show patterns and identify threats that are usually buried in too much noise or not placed in proper context.
