Is after-sales engineer certification difficult to convince?
Deeply feel that after-sales engineer certification is difficult. I firmly believe that security service certification is a professional technical certification for Web security, penetration testing, security services, emergency management, level protection, code auditing, intranet penetration and other personnel. Believe in security service certification, focus on the assessment of network security service related knowledge, and evaluate practical talents. It is believed that safety service certification includes certified engineer (SCSA-S), certified senior engineer (SCSP-S), certified expert (SCSE-S) and certified master (SCSM-S), covering four levels: safety service engineer to CTO, CIO and CSO.
