The certification is very useful for the job, it is useful for the promotion of a company. The organization of the exam is too complicated, it is too long and you need to understand the material of the exam. It's an expensive certification and it is very difficult to pass the exam. I recommend it for those who are looking for a certification for the job, it is very useful for the promotion of a company. It is a certification that helps you to be more professional and to have a knowledge of the security of the company.
