Online CompTIA IT Certification Training FAQs

The A+, Network+, and Security+ certifications are sequential. A+ focuses on devices; Network+ is dedicated to the hardware, software, and protocols for networking; and Security+ adds the layer of core security functions across devices, networks, and the organizations that deploy them.

CompTIA calls the A+, Network+, and Security+ sequence a “stacked” credential that validates baseline skills in the three disciplines: devices, networks, and security. Each individual certification is considered an independent signal of competence in the area it addresses.

According to CompTIA, the A+ certification is often associated with baseline or entry-level support positions such as service desk analyst, technical support specialist, field service technician, associate network engineer, data support technician, desktop support administrator, end-user computing technician, help desk technician, or system support specialist.

According to CompTIA, the Network+ certification is often associated with positions such as network administrator, network field engineer, computer technician, help desk technician, system engineer, network support specialist, or network analyst.

According to CompTIA, the Security+ certification is often associated with junior IT auditor or penetration tester positions. Other titles might include systems administrator, network administrator, or security administrator.
