Joined by a panel of cyber insurance and privacy professionals, Carolyn leads a lively discussion on the latest cyber litigation trends, including data breach class actions and privacy claims. The panel provides practical strategies in defending these types of cases, starting from early incident response considerations, through motion practice, discovery, expert testimony, and finally to identifying damages and settlement options.
