Norwest Venture Partners and Lightspeed Venture Partners and others have made a $20m Series A investment in Fireglass, a company founded by Israeli cyber security veterans based in New York, that is focused on a new approach to preventing cyber attacks on large enterprises and financial companies. The approach is still under wraps.

This investment underscores the continuing trend by the venture community to commit significant sums early to promising cybersecurity companies addressing the protection of corporate networks.
