This week, a Cambridge, Mass.-based security startup BitSight Technologies unveiled a new service that aims to score the security effectiveness of thousands of businesses. The goal is to help companies scrutinize the risks posed by the security posture of their business partners. Norse and Lookingglass Cyber Solutions also have demonstrated technologies that analyze live web traffic to detect botnets and other cybercriminal activity emanating to and from corporate networks. They say the data could be used to reduce the risks posed by business partners and customers. Some experts say the erosion of trust in technology firms associated with the NSA surveillance activity could prompt a desire for better visibility into the security culture and expertise of solution providers.
