The Certified Information Systems Security Professional (CISSP), as the flagship certification of ISC², is still regarded in 2025 as one of the most influential credentials in the field of information security management. Although technology is constantly evolving, what organizations truly lack are professionals with “systematic security decision-making capabilities,” and the CISSP is centered on cultivating this core skill. (ISC² confirms CISSP is “The World’s Premier Cybersecurity Certification”).
According to the latest ISC² industry report for 2025, the global cybersecurity job shortage still exceeds 4 million, and the CISSP consistently remains in the top three positions for hiring priority.
