About Counterpane Internet Security

In the burgeoning digital age of 1999, cryptographer and security expert Bruce Schneier founded Counterpane Internet Security. The company was built on a simple, yet powerful, premise: instead of just selling security products, they would provide a managed security monitoring service. Counterpane's experts would act as 24/7 watchers for corporate networks, detecting and responding to threats in real-time. The company's approach to proactive threat monitoring was a novel concept, moving beyond the traditional model of selling firewalls and antivirus software. This service-oriented model attracted significant attention and investment, with the company raising $47 million over two funding rounds. This capital allowed them to build out their Security Operations Centers and serve a growing list of Fortune 100 clients. The pivotal moment for Counterpane came in October 2006 when it was acquired by British telecommunications giant, BT Group. The acquisition was a strategic move for BT to bolster its own managed security offerings. Following the deal, Bruce Schneier stayed on as Chief Technology Officer and Paul Stich remained as CEO, signaling the value BT placed on Counterpane's leadership and expertise. The acquisition marked the successful journey of an idea from a recognized expert into a core component of a global telecommunications powerhouse.
