If you want to enter the profession or establish a strong career, one of the most well-known vendor-neutral certification programs in the IT business is offered by CompTIA. A training and testing process is required to earn a CompTIA certification, which verifies knowledge in a particular IT support function.

Four categories—Core, Infrastructure, Cybersecurity, and Additional Professional qualifications—are used to categorize the certifications.
