CEO Enrique Salem talked about the kind of "profound change" the security industry has experienced over the last 20 years. To underscore how far the industry has come, Salem referenced his former employer Peter Norton. Back in the early 1990s, viruses traveled on floppy disks and antivirus updates were applied once every three months, he said. Twenty years later, the world is dealing with a total of 800,000 petabytes of data, Salem said, compelling Symantec to rethink its security paradigm to one that revolves around people and information. "We hear the same things over and over again. This is a time of profound, meaningful change," he said. "This session at Vision is about rethinking our approach."
