The latest episode of The Leaders’ Room podcast season four features Thomas Parsons, head of Tenable in Ireland and VP of product management. This series is created in partnership with IDA Ireland.
Once again in season four of The Leaders’ Room podcast, we get to know the leaders of some of the most influential multinationals in tech, life sciences and innovation, as well as getting insights into their leadership styles and the high-tech trends they see coming down the line.
In this latest episode, we speak to Thomas Parsons, who heads up threat exposure cybersecurity company Tenable in Ireland as well as serving as VP of product management for the Maryland-based company, about a career that parallels the evolution of the cyber threat landscape since the ’90s, and a style of leadership that spots the best cybersecurity talent sometimes in the least expected places.
It’s a fascinating listen charting Parsons’ distinguished career in cybersecurity, from Symantec, via Intel to Tenable which he joined shortly after the exposure management company arrived in Ireland in 2016. Parsons was indeed Tenable’s first R&D hire in 2017, and today some 50pc of the 140-strong Irish team work on the R&D side in Dublin, he tells us.
In a series on leadership, Parsons got to work at Symantec at a time when a renowned leader took the reins – John Thompson. A longtime IBM alumnus, Thompson radically changed how Symantec thought about security for organisations, at a time when large-scale cybercrime and nation-state attacks were not yet on the agenda. Under Obama, Thompson was considered for the role of Secretary of Commerce, and Nancy Pelosi appointed him to the Financial Crisis Inquiry Commission in 2009.
Parson also got to experience first-hand the process of Tenable going public, including being on the ground in New York on the day it did so. His thoughts on how good leaders in his sector need to keep an eye out for talent in places you might least expect are well worth a listen as are his insights on what might be coming down the line.
We’re grateful to all our interviewees again this season, for taking the time out of busy schedules to come into the studio and share their insights and their intelligence with us. And a big thanks as ever to our partners IDA Ireland who make this series possible.
