MCI has launched its NetSec Security Risk Management Service, a new managed solution that helps companies improve their security by quantifying, prioritising and remediating security risks across an enterprise. MCI's latest cloud-to-core offering enables companies to enhance their ability to take proactive decisions and initiate immediate action against threats and vulnerabilities, when and where it most needed. The service will be available to U.S.-based companies, including multinationals beginning in January 2006.
