Training by — opinions?

I need to learn DevSecOps quickly, and found the classes/certs by Practical DevSecOps Online Training. I am interested in their CDP and CDE specifically, as their syllabuses cover a lot of the areas I am interested in. The couple of online reviews I’ve found are very positive.

Are these classes good? If you have taken them, could you share your experience?

About me: I am experienced in development (Linux/Python most strongly) and in "classical" security (code review and incident handling), but new to the whole DevOps/DevSecOps world, so little practical knowledge of cloud security, Docker/Kubernetes subtleties, etc. Given constraints of family, work etc. I have decided that external structured training (plus ad-hoc labs when time allows) is the best way to absorb a lot of knowledge quickly.

Thanks for your feedback!
