Leads effort to share critical security practices across financial sector

Reston, VA, December 7, 2023 – FS-ISAC, the member-driven, not-for-profit organization that advances cybersecurity and resilience in the global financial system, today announced the appointment of John Denning as Chief Information Security Officer (CISO). Denning’s appointment will be effective as of 1 January, 2024.

Denning joins FS-ISAC from Bank of America, where he spent thirteen years; 11 years within Global Information Security.  His most recent role within the Bank was Global Compliance and Operational Risk Executive responsible for second line of defense for Global Markets Technology, Global Markets Operational Technology and Global Banking Technology, focusing on risk identification and reduction. He also served as Senior Vice President of Cyber Crime Prevention, Identity and Access Management and lead the Cybersecurity Threat Intelligence team. Prior to Bank of America, John held roles as the Director of External Affairs for the US Department of Homeland Security’s Office of Cybersecurity and Communication and spent eleven years as a congressional staff member focused on cybersecurity, telecommunications and critical infrastructure protection. 

“At my core, I believe information sharing is foundational to protecting our financial infrastructure from ever-changing cyber threats,” said Denning. “I am proud to be joining the leading cyber intelligence sharing organization for the financial services sector and look forward to contributing to this important mission.”

In addition to leading FS-ISAC’s internal cybersecurity and risk management functions, Denning will strengthen FS-ISAC’s work of curating and disseminating critical baseline cybersecurity practices across the financial sector, including working with global financial institutions to ensure the entire sector has access to the deep knowledge of those with the most mature cyber defense programs. 

“The cyber risk landscape continues to rapidly evolve, and the financial sector needs a comprehensive understanding of not only cyber threats specific to financial services, but also how we can respond with agility to those threats to minimize the risk to our firms and customers,” said Steven Silberstein, Chief Executive Officer, FS-ISAC. ”We are thrilled to have John Denning join us, further strengthening our global cyber leadership team.”  

“It is critical that financial services companies work both together and across sectors to bridge gaps, integrate new ideas, and encourage diversity of thought,” said Ann Barron-DiCamillo, Managing Director, Global Head of Cyber Operations at Citi and Chair of FS-ISAC’s Board of Directors. “John’s 20 years of expertise and passion to enhance the security of our sector make him the perfect fit to contribute to this effort.”

Denning will replace Linda Betz, a veteran CISO who has served as FS-ISAC’s interim CISO since February 2023. Betz remains with the organization as EVP of Global Community Engagement, ensuring that FS-ISAC continues to serve its many communities focused on regions, sub-sectors, specific roles, and key topics.
