The SC0-402 exam — officially the Network Defense and Countermeasures (NDC) — is SCP's certification exam for professionals who work with its technologies, and passing it awards the Network Defense and Countermeasures (NDC) certification at the Professional level. Vendor-issued credentials like this one remain among the clearest signals of skill a resume can carry. It also connects naturally to SCP Security Certified Program, SolarWinds Certified Professional as a next step.
