Leif Dreizler, senior application security engineer at Segment, doesn’t consider himself a developer. Some of his colleagues disagree. Leif, who didn't know what computer science was when he signed up for his first CS class, unexpectedly gravitated towards the major. Although his specialization in appsec started from security consulting during his senior year of college, his background has helped embed security into engineering. Leif joined the podcast to discuss his journey into appsec, his observations about the industry, and his recommendations for entering the field.
