The main challenges on the journey to the cloud are not technical, one of the most important challenges is training.
It is a key success factor that your analysts know about the infrastructure they need to protect.
Here’s some advice on how to create the learning path for your organization:
Skill Builder offers many on-demand video trainings for free: Skill Builder Some trainings require a subscription (not free), mainly the ones that include hands-on labs and AWS Jams. More details here
There are many training resources available in the Ramp-Up Guide .
If you prefer formal education guided by instructor, with labs, you can leverage the Architecting on AWS course, that will help you understand the infrastructure you need to protect, and the Security Engineering on AWS course, that is an excellent resource to gain a theory and practical foundations. Both courses are 3 days long and are available in multiple languages.

To gain hands-on experience, there are numerous security workshops on AWS at https://workshops.aws to do in your AWS accounts or you can use temporary AWS Accounts if you have an AWS Skill Builder subscription
The AWS Certified Security Specialty certification will help you validate that your team has the knowledge required to perform their role, or to show your peers that you managed to acquire that knowledge.
To study for the certification, there are many resources, including this book, where you will find the theory, practical exercises, tips and sample test questions to evaluate your knowledge, and identify areas of improvement: Study Guide: AWS Certified Security Study Guide: Specialty (SCS-C01) Exam

I also invite you to visit the Webinars section where you can see deeper videos on different AWS Cloud Security topics.
Finally, beside the cloud security training, ensure that ALL employees in your company go through a Security Awareness Training periodically to ensure that they are aware of how adversaries operate, and not to disclose any sensitive information, or doing insecure tasks like sharing passwords or using unsecure communications channels.
Amazon provides it’s own Cybersecurity Awareness training for FREE, and it’s available in multiple languages.
