The Most Influential People in Security 2021

Security is pleased to announce our 2021 Most Influential People in Security – 10 top security executives and industry leaders who are positively impacting the security field, their organization, colleagues and peers, and the national and global security landscape.

Now, in its 12th year, Security’s Most Influential People in Security offers readers a glimpse into some of the influencers within the security sector that deserve recognition for the unique qualities they each bring to their jobs, their organization and to the industry.

These security leaders have been nominated by their colleagues and associates and were chosen based upon their leadership qualities and overall positive impact on stakeholders, enterprises, colleagues, constituents, and the general public.

Here you will find brief overviews of each honoree’s career path, goals and accomplishments – in many cases across both the public and private sectors – as well as advice for those security professionals looking to follow in their footsteps, including being a security generalist, investing in lifelong education, seeking mentors and more.

Our special appreciation goes to Jerry Brennan, who was a project partner on this report and provided subject matter expertise and research.
