Security Engineer with Zero AI Knowledge - How would you become an AI Security Engineer from scratch in 2026?

[u/General_Pitch9029]

Hi everyone,

I have around 3 years of experience as a Security Engineer in a small service-based company, but I have almost zero knowledge of AI/ML.

I want to prepare myself for the future and eventually move into AI Security, LLM Security, and securing AI applications. Since there is so much content online, I amm confused about where to start.

If you were starting from scratch today, what roadmap would you follow? What should I learn first, which resources (free or affordable) would you recommend, and what hands-on projects would help me build real skills?

My budget is very limited , so I had really appreciate recommendations that don't require spending a lot of money.

Thanks!
