CompTIA Certification Guide: A+, Security+ & Career
Oliver Jones
⚡ Smart Summary
CompTIA certifications are vendor-neutral IT credentials covering technical support, networking, cybersecurity, cloud and project management, from the entry-level Tech+ through the expert-level SecurityX, and are recognized by employers and government agencies worldwide.
What is CompTIA Certification?
CompTIA certifications are among the most trusted credentials in the IT industry because they are vendor-neutral: they test skills that transfer across Windows, Linux, macOS and every major cloud, rather than a single supplier’s products. CompTIA works with international focus groups and IT leaders worldwide to define each certification program and write the exam objectives.
Most CompTIA certifications are valid for three years and renew through continuing education. Exam codes refresh on a similar cycle, so check the active version before booking.
How to Start a Career with CompTIA Certification?
If you are looking to start an IT career with a recognized credential that is readily accepted by employers worldwide, CompTIA certification is a practical place to begin. The programs build the critical thinking and problem-solving habits that modern enterprise networks demand.
The certification programs are structured to suit your time and convenience: you can take a self-study route or instructor-led training. They also serve students, educators, entrepreneurs and enterprises, with the shared goal of raising information technology skills across the industry.
CompTIA Core Certifications
The core skill certifications are CompTIA Tech+, CompTIA A+, CompTIA Network+ and CompTIA Security+. They are designed to be taken in roughly that order, as the diagram below shows.
The CompTIA Tech+ Certification
This certification is for anyone looking at a career switch into the IT sector. It imparts basic knowledge of IT terminology and concepts, database fundamentals, application software concepts and the purpose of application architecture. You will also cover the infrastructure basics needed to set up a wireless network. Tech+ (exam FC0-U71) is the successor to CompTIA IT Fundamentals (ITF+), which CompTIA has retired.
The CompTIA A+ Certification
In this certification you gain knowledge of hardware and its components, networking and network protocols, and learn to configure and connect mobile devices such as tablets and smartphones. You also learn to troubleshoot hardware and software using decision trees, and to work across operating systems including Windows, macOS, Linux, Android and iOS. A+ is earned by passing two Core exams rather than one.
The CompTIA Network+ Certification
This certification helps you gain expertise in IT infrastructure and network protocols. With it you can design, configure, manage and troubleshoot networks, and identify the strengths and weaknesses of an existing network. Network+ currently uses exam code N10-009.
CompTIA Security+ Certification
Security+ concentrates on current trends in security management, risk management and mitigation, threat management and intrusion handling. With this certification a cybersecurity professional can recognize, respond to and report security incidents. Security+ uses exam code SY0-701 and is CompTIA’s most requested credential.
CompTIA Cybersecurity Certifications
Once Security+ is behind you, three credentials cover the analyst, tester and architect roles.
CompTIA CySA+ Certification
This cybersecurity analyst certification helps you counter threats using behavioral analytics, and covers malware and advanced persistent threats. You learn to configure threat detection tooling, run threat and vulnerability management, and respond to incidents. CySA+ uses exam code CS0-003.
CompTIA SecurityX Certification (formerly CASP+)
The advanced security practitioner credential helps professionals implement cybersecurity policies and frameworks in practice. It is aimed at senior engineers and security architects who want to stay technical rather than move into management, and it covers enterprise security operations, advanced cryptography and the security impact of emerging technologies like AI.
CompTIA renamed CASP+ to SecurityX when exam CAS-005 launched on 17 December 2024; the previous CAS-004 exam retired on 17 June 2025. Existing CASP+ holders keep their credential and receive the SecurityX badge automatically.
CompTIA PenTest+ Certification
The penetration testing certification is for cybersecurity professionals who run authorized tests and vulnerability assessments in order to protect a network against attack. You learn to scope and plan compliance-based assessments, and to test across mobile devices, desktops, servers, web applications, APIs and cloud environments. PenTest+ uses exam code PT0-003.
CompTIA Infrastructure Certifications
Here are the important infrastructure certifications for CompTIA, covering cloud, Linux and server administration:
CompTIA Cloud+ Certification
The cloud certification validates security and networking work carried out on cloud platforms. It is vendor-neutral, so it proves you can maintain and optimize cloud infrastructure services across providers rather than on one platform. Cloud+ uses exam code CV0-004 and now covers DevOps and multi-cloud troubleshooting.
CompTIA Linux+ Certification
The CompTIA Linux+ certification suits IT professionals who administer Linux in their organizations. Enterprises run Linux across cloud platforms, cybersecurity tooling, containers and web applications, and the current Linux+ exam, XK0-006, reflects that by adding automation and container topics.
CompTIA Server+ Certification
The server certification covers server technologies including virtualization, storage, security and troubleshooting, and validates your skills as a server administrator. It helps you understand server architecture, apply network data security to servers and support storage devices. Server+ uses exam code SK0-005 and is the one CompTIA credential that never expires.
CompTIA Additional Certifications
Here are some other important CompTIA certifications, aimed at project delivery, training and cloud literacy:
CompTIA Project+ Certification
The project certification is useful for managers and business professionals who run small to mid-sized projects that are not highly complex. Alongside managerial skills, you learn the project management techniques needed to handle scheduling, documentation and governance. Project+ uses exam code PK0-005.
CompTIA CTT+ Certification
The certified technical trainer certification covers the skills needed to teach a group. It validates knowledge of the tools and techniques a trainer relies on, so you become an effective communicator who can manage classroom or virtual training and run assessments confidently in front of an audience.
CompTIA Cloud Essentials+
Cloud Essentials+ was aimed at business professionals new to IT who needed to understand cloud principles, and at non-IT staff whose employer was adopting cloud platforms. CompTIA retired it in September 2025; Tech+ or Cloud+ are the current alternatives.
