BT – formerly known as British Telecom – conducts forums known as BT's Big Thinkers series.
F-Secure's Chairman of the Board, Risto Siilasmaa, was a panelist during a recent discussion along with Michael Barrett, the Chief Information Security Officer of PayPal. It was hosted by well-known security expert Bruce Schneier, and was moderated by Esther Dyson.
The discussion is about an hour in length. It takes a minute or two for the video to load from BT's site, probably due to the demand at the moment. Be patient, it's worth the wait.
