The CC is ISC2's entry-level certification without experience requirements and explicitly targets career starters, career changers, and students. Notably, ISC2 periodically offers CC training and the exam for free (as part of the 'One Million Certified' initiative), which has significantly increased market penetration. Content covers five domains: Security Principles, Incident Response, Access Control, Network Security, and Security Operations – at a solid but intentionally broad entry level. As a stepping stone to SSCP or CISSP it is well-suited; as a standalone credential it carries less weight than Security+. From September 2026, a new Exam Outline applies.
