About the best IT Certifications courses
Frequently asked questions
The most-reviewed course in this category is CompTIA Security+ (SY0-701) Complete Course & Practice Exam by Jason Dion, with about 123,300 reviews at 4.7 as of October 2026. Our guide to the best IT certification courses picks a course for each exam.
Exam prep for CompTIA A+, Network+ and Security+, Cisco CCNA, Microsoft Azure (AZ-900, AZ-104, AZ-204), Google Cloud, ITIL 4, Salesforce administrator, CISSP and Lean Six Sigma.
Paid Udemy courses include a certificate of completion, but that is not the certification itself. Exams such as CompTIA Security+, Cisco CCNA and Microsoft AZ-900 are set by the vendor and booked with the vendor or its testing partner; the courses here prepare you for them.
