Deborah Rimmler

Throughout her career, Deborah has built and led integrated privacy, information security, and compliance programs within multinational and private-equity-backed organizations. As General Counsel of Sigma7 Group, she designed and operationalized a portfolio-wide privacy program using Keepabl, bringing multiple acquired companies into the UK and European Union General Data Protection Regulation and U.S. state privacy compliance while closely aligning privacy governance with maturing information security operations, incident response, and third-party risk management. Previously, at Dentons, she served as Global Compliance Officer and Counsel, working alongside global security and privacy leaders to align third-party risk programs, streamline OneTrust to align information security and privacy use, and had daily management oversight of multi-million-dollar firm-wide information security uplift initiatives to align 40 member firms of varying maturity with ISO 27001 controls.

Deborah is recognized for her ability to build constructive, high-trust client engagements by bridging technical complexity, business objectives, and legal requirements. At Dentons, she designed and led tabletop cybersecurity and privacy exercises for firm leadership and global clients, helping executives prepare for real-world incidents while strengthening long-term client relationships. She also oversaw outside technical information security advisors supporting global and domestic energy clients, translating complex technical findings into practical guidance aligned with client operations and compliance obligations. At Sigma7, Deborah worked closely with the threat intelligence software-as-a-service team to develop a strategic partnership with a technology provider, enabling new product offerings while navigating complex, multi-jurisdictional privacy considerations.
