 Geoff Wilkerson
 Open Trusted Technology Forum Co-Chair
 Seagate Technology



Geoff Wilkerson is a member of the Product Security Office at Seagate Technology, where his primary focus is security compliance and managing product certifications. Geoff's background is in project management, information security, and supply chain security. A member of the OTTF for several years, Geoff was one of the earliest advocates for Seagate to champion the use of the O-TTPS as a product lifecycle standard. Geoff lives in Oklahoma City with his wife and three children.

Geoff sees the next couple of years as a flashpoint for cyber and product security. 2020 was a major disruption to the lives of most people and businesses and highlighted the evolving and expanding threat surfaces that malicious actors can and will exploit. Geoff believes there will be an increased interest in trusted technology capabilities in the near future, and the OTTF can serve as an enabling body to meet that interest. As Co-Chair, he aims to facilitate that beneficial exchange and aid organizations in their efforts to strengthen their security postures.

Al sees the next couple of years as a critical point in the evolution of cyber and product security. The past couple of years have shown both government and industry are constantly exposed to an evolving and ever-expanding array of threats from a global pool of malicious and state-sponsored actors. These exploits revealed the need for trusted technology capabilities in the near future. Al believes the OTTF can serve as an enabling body to meet these needs and stimulate interest in the subject. As Co-Chair, he aims to facilitate that beneficial exchange, aid organizations in their efforts to harden their security postures, and strengthen the cooperation between government customers and their industry partners.
