SAN FRANCISCO — Every year since 2002, Cooley special counsel Randy Sabett has spent a week at the RSA Conference. RSA is the world’s biggest security conference, and it’s long drawn tens of thousands of professionals—engineers, risk managers, executives, entrepreneurs—to share threat scenarios and security strategies surrounding the world’s vast and increasingly connected systems and data stockpiles.

Sabett said he’s seen a growing number of lawyers at the conference each year, a trend that has only accelerated after a few high-profile breaches made cybersecurity the hot practice area of the moment. “There’s a lot of people practicing [cybersecurity law] now, but there’s a core group of us who have been doing it for a very long time,” he said.
