Managing Member Jennifer A. Coughlin joins the ABA’s Products Liability & Life Sciences Regional CLE Program on October 22, presenting the session “Tick Tock: The First 72 Hours of a Cyber Incident” alongside Sarah Dufendach of Beazley, Margaux Weintraub of Marsh MMA, and Jennifer Polliard of IronGate Security.
What happens when the call comes in notifying you that systems are compromised, operations are disrupted, and sensitive data may be at risk? Jenn and the panelists walk attendees through the crucial first hours after a data privacy and security incident occurs and examine what needs to be done first from all key areas of incident response including legal, digital forensics, insurance, and communications. The panel also explores how these decisions impact business’ operations, regulatory and litigation exposure, insurance coverage, reputation, and financial bottom line.
