For all those, who are passionate to learn network security, your first stop should be EC-Council Certified Network Defender (C|ND). The C|ND courseware helped me understand the different modules in the program. Plus, there is no other training program that can cover this domain with such information. I wouldn’t have been able to attain the C|ND credential without going through this advanced training. My experience involves high-quality labs, brilliant content delivery by an experienced instructor, and encyclopedic knowledge of the domain. It also covered various important networking topics which made this entire learning experience very relatable to real-world scenarios. After this, I am planning on progressing further through the path of credentials.
I would promote C|ND because it helped me to learn different aspects of network security and laid out a sound plan for my continuous professional growth.
