This is a list of over 100 free DFIR and Cybersecurity related training courses and resources that I’ve heard of.
When I was trying to get into the field, there was so much I wanted to learn, but I couldn’t afford training. Most of the training in this list are things that I’ve needed to know and still need to learn as an Incident Response Analyst. I hope this list helps everyone reach their goals regardless of their financial status. This list is updated on a regular basis. Thank you to all of the trainers and course creators for making your content free!
