Privacy & Cybersecurity
Position
John Tomaszewski specializes in emerging technology and its application to business. His primary focus has been developing trust models to enable new and disruptive technologies and businesses to thrive. In the “Information Age”, management needs to have good advice and counsel on how to protect the capital asset which heretofore has been left to the IT specialists – its data.
John’s expertise in the understanding of a company’s data protection and management needs provide a specialized point of view which allows for holistic solutions. A good answer should always solve at least three problems.
As the co-leader of the Global Privacy & Security practice, John has significant experience counseling companies regarding data protection and information security throughout the Americas, Europe, and Asia. John regularly develops and implements data protection compliance programs for human resource outsourcing companies, cloud service providers, social media companies, and a host of traditional brick-and-mortar and emerging-technology clients. He also drafts and negotiates data licensing and technology transfer agreements, advises on the viability of digital signatures, consults on identity management systems, and addresses novel legal issues with artificial intelligence and autonomous vehicles. His clients have included myriad technology companies, as well as financial services, pharmaceutical, and e-commerce businesses of all sizes.
John has been a co-author of several information security and privacy publications, including the PKI Assessment Guidelines and Privacy, Security and Information Management: An Overview; as well as publishing scholarly works of his own on the topic. He has also provided input to the drafting of various security and privacy laws around the world; including the APEC Cross-Border Privacy Rules system. He is a frequent speaker globally on the topics of cloud computing, Self Regulatory Organizations (“SROs”), cross-border privacy schemes, and secure e-commerce.
