Cisco appoints former Thomson Reuters CIO, Jacqueline Guichelaar, as group CIO

Cisco has named veteran tech leader, Jacqueline Guichelaar as its new group CIO. She takes over from Guillermo Diaz after his 19 year long stint as global CIO.


Networking and security giant, Cisco has appointed Jacqueline Guichelaar as its group chief information officer. Guichelaar joins Cisco from Thomson Reuters, where she was heading IT operations as Group CIO.

At Cisco, she will be responsible for the entire technology infra and application development globally. On her post, she shared that she is passionate about driving Cisco’s digital strategy in close partnership with its business and OneOps team. She said she’s proud to be leading “one of the best IT teams on the planet”.

Guichelaar has been spearheading IT across top global enterprises for a remarkable 25 years and 6 months. Prior to her stint at Thomson Reuters, she had worked as CTO and director of technology at Lloyds Bank, Deutsche Bank, National Australia Bank, IBM and DXC Technology.

With 28 years of experience in the technology space, she has had a front-row view at the developments in enterprise IT, especially the BFSI sector. And as a technology leader, she has had the opportunity to adopt and deploy emerging technologies. 

Her LinkedIn account highlights a sustained track record of delivering large-scale transformations through a structured approach and strict governance. She was also the Chair of the 2012 Women on Wall Street Conference.

Guichelaar’s predecessor, Guillermo Diaz, Jr., joined Cisco back in 2000 and is credited with driving the company’s transformation from Cisco IT networked infrastructure to primary business application areas, which includes the company’s USD48B e-commerce, professional services, customer service, and SaaS platforms.
