Vendor-neutral generalist vs. Cisco specialist
The CISSP is a vendor-neutral senior credential spanning the full security discipline. It does not test mastery of any specific product or platform. Its value is broad conceptual capability and integrated judgment.
CCNP Security is a Cisco-specific professional-level credential focused on configuring, troubleshooting, and operating Cisco's network security products. Candidates must pass two exams: a core security technologies exam plus one of several concentration exams (Cisco Firepower, identity services engine, secure access, security automation, or others). The credential validates deep hands-on capability in the Cisco ecosystem.
