The CTO role will enable PKI Solutions to not only expand its consulting capabilities and continue to mature PKI Spotlight 


PORTLAND, Ore., Sept. 14, 2022 — PKI Solutions, a leading cybersecurity firm providing Public Key Infrastructure (PKI) products, services, and training, today announced that Shawn Rabourn has been added as Chief Technology Officer. 


With over two decades of full-range information security and identity management experience in engineering, design, and architecture roles, PKI Solutions is pleased to have Shawn join the team. His background includes time in the trenches with Azure, Active Directory, Certificate Services/Public Key Infrastructure, Identity Management, Enterprise Governance and Risk Management, Business Continuity, and Compromise Response. 


Shawn worked 21 years at Microsoft, his final role started when he joined the Microsoft Consulting Services Americas Cybersecurity team in June 2014. He helped his customers improve their security posture and reduce risk.  


On his new role, Shawn said, “I can't wait to be a man among titans, PKI Solutions has built an elite roster and I am humbled to be included.”

A snapshot of his background includes roles in Product Support Services (PSS) on the Enterprise Platforms Support Directory Services team (2001-2005), and in Premier Field Engineering; both as a Windows Server generalist (2005-2006) as well as on the Scarce Skills team specializing in MIIS/ILM, ADLDS, and ADRMS (2006-2007). Shawn’s most recent role was as a Principal Consultant with the Microsoft Consulting Services Azure Data and Artificial Intelligence practice. Prior to his service in MCS, Shawn was a senior Security Consultant with the ACE Infrastructure Services team, the consulting arm of Microsoft IT Information Security and Risk Management. With the ACE team, he assisted customers in Active Directory, ADFS, PKI/ADCS, and FIM specialized engagements and many other security-centric opportunities, as well as held ownership of nearly 40 IT Security Standards, and held a security officer role for certain business-critical BCDR responsibilities. During his time at Microsoft, he handled over 2,500 customers, including over 250 unique onsite customer visits. 


PKI as an assemblance of technology has truly proven itself to be resistant to obsolescence and is included in every vision of the future. We must continue to enable our customers to provide PKI services to their applications and infrastructure and strengthen their cybersecurity posture. A great PKI can serve as an excellent deterrent to determined adversaries in a world where our IT infrastructure is constantly under attack,” said Shawn. 


Shawn promises that he has “a few other tricks up my sleeve”. PKI Solutions is excited to have him on board. 


I am excited to have Shawn join us as we continue our growth with the launch of PKI Spotlight. Shawn’s experience in delivering PKI consulting to organizations around the world will enable us to not only expand our consulting capabilities but will enable us to continue to mature PKI Spotlight. He will be integral to the roadmap and future of PKI Spotlight and ensuring our customer needs are properly reflected in our continued innovation,” Said PKI Solution’s president and founder, Mark B. Cooper.
