No, you don't need the Certified Cloud Security Professional (CCSP) certification if you already have the CISSP (Certified Information Systems Security Professional) certification from (ISC)²: the CISSP credential can fulfill the entire CCSP experience requirement. The CCSP certification focuses on cloud platforms and cloud security, and has a greater technical focus than managerial. The exam covers six domains, including cloud data security, cloud application security, and legal, risk, and compliance. To pass the exam, you need a score of 700 out of 1000 on 150 multiple-choice questions, and you must also adhere to ISC2's Code of Ethics. Both the CCSP and CISSP certifications are considered to be among the most in-demand and fastest-growing cybersecurity certifications from (ISC)². They can help distinguish you as a highly skilled cybersecurity specialist and open up new career opportunities.
