Simply Defensive

In this episode of Simply Defensive, hosts Josh Mason and Wade Wells sit down with Tom Dejong, Triage Lead at Black Hills Information Security (BHIS). Tom shares his unconventional path into cybersecurity — from a South Dakota apprenticeship scholarship to becoming one of the most detail-oriented analysts in the BHIS SOC. The conversation covers the realities of SOC triage, the importance of detailed documentation, mentoring new analysts, and how AI is reshaping (but not replacing) blue team work.
