As Director of Data Architecture, Scott Hollenbeck manages a team of researchers focused on applied metadata, reputation and Web service technologies in collaboration with university partners. Mr. Hollenbeck is the author of the Extensible Provisioning Protocol (EPP), a standard protocol for the registration and management of Internet infrastructure data including domain names. Mr. Hollenbeck is also a co-author of the Verisign Registry-Registrar Protocol (RRP), a pre-cursor of EPP developed for use in the VeriSign Shared Registration System. He has been a contributor to several industry efforts related to domain names and Internet security, including internationalized domain names, ENUM, public key cryptography, S/MIME, the Extensible Markup Language (XML) and the Transport Layer Security (TLS) protocol. He has served as a member of the Internet Engineering Steering Group of the Internet Engineering Task Force, where he was the responsible area director for several working groups developing application protocol standards.

Prior to his employment at Verisign, Mr. Hollenbeck held management and engineering positions with Xerox Corporation. He is a former chairman of the Xerox desktop software interoperability test working group, a cross-corporate group of engineers and managers responsible for interoperability testing of all Xerox network and desktop software products. Mr. Hollenbeck is also a former officer of the United States Air Force.

Mr. Hollenbeck is an avid classic automobile hobbyist and recreational athlete. While an undergraduate at the Pennsylvania State University he was selected to the 1984 All-American Fencing Team.

During the course of his professional career Mr. Hollenbeck has developed expertise in the Domain Name System, applications programming, systems architecture, network engineering, information security, financial analysis and personnel management. He holds a Bachelor’s degree in Computer Science from the Pennsylvania State University and a Master’s degree in Computer Science complemented by a graduate certificate in Software Engineering from George Mason University.
