Invest in the Expense: Implementing Cyber Coverage to Combat the Ever-Evolving Risk Landscape

At CLM’s Annual Conference 2025 (AC25) on April 11 in Texas, Mullen Coughlin Partner Carolyn Purwin Ryan joins the panel session, “Invest in the Expense: Implementing Cyber Coverage to Combat the Ever-Evolving Risk Landscape,” alongside cyber insurance and incident response professionals from Tokio Marine – Catherine Lyle and Jenna Canet – as well as Gallagher Bassett’s Kirsten Mickelson.

This session highlights emerging cyber threats and explores how cyberattacks, such as ransomware and supply chain vulnerabilities, are now beginning to pose a financial threat greater than the cost of cyber coverage, as well as threats to organizational reputation, operations and client data. Carolyn and the rest of the panel share real-world examples of threat actors exploiting security gaps to deploy ransomware and provide practical steps and best practices that organizations can take to strengthen their cybersecurity efforts.
