There is a method for machine-controlled legal portfolio monitoring. The method has the following steps: a) obtaining securities transactional data from multiple financial firms for a system; b) processing the securities transactional data to calculate losses in the system; c) permitting law firms to view the losses in the system without revealing the identity of the multiple financial firms; d) permitting the law firms to submit to the system security litigation proposals to financial firms that have incurred losses; and e) allowing financial firms that have incurred losses to respond to the security litigation proposals by engaging directly with a particular law firm through the system. There is also a system. There is also a storage medium.
