Certified Container Security Expert CCSE

Container Security Expert is the training program for professionals tasked with securing the container environment. The course allows you to get hands-on experience as you work with live containers in our lab, gaining significant insights that will arm you to secure a containerized platform in any environment. 

After the training, you will be able to:

  • Building solid foundations that are required to understand the container security landscape
  • Embedding security while creating, building container
    images, and securing running containers
  • Gaining knowledge in limiting the blast radius in case of a container compromise
  • Gaining expert skills in analyzing container weaknesses, attacking containers, and defending containers through various tools and tactics
  • Gaining abilities to apply practical container security skills in real-world container deployments

This course (CCSE) is the second course I have taken from Practical-DevSecOps, the other was the Certified DevSecOps Professional and I love the content and format. The content is great: relevant, topical (up to date) and the practical-hands-on approach is what sets this course above the others.

Practical DevSecOps is an excellent opportunity to learn more about the strengths and weaknesses of containers and how to improve them. Practice exercises make it easy even for beginners.
