CompTIA Security+ (SY0-701) Complete Course & Practice Exam (Udemy.com)

CompTIA Security+ (SY0-701) Bootcamp - Your preparation for the world's best cybersecurity certification!

Created by: Jason Dion

Last updated September 2026

Our take

Based on the ratings of 123,340 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.

This is Jason Dion's Security+ course, rebuilt around the current SY0-701 objectives: 265 lectures across 30 sections covering everything from social engineering and cryptography to incident response and governance. It ships with a downloadable study guide, section quizzes, and a full practice exam. The course was updated just this month, so it is not one of the stale certification courses still teaching a retired exam version, and has more than 123,000 reviews on Udemy.

Reviewers who passed the exam, and there are a lot of them, credit the course as their main or only study source, several mentioning first-try passes with scores in the 80s. People like that the quizzes explain wrong answers instead of just marking them wrong, and that Dion's explanations land clearly. Complaints cluster around pacing and format: a few reviewers found sections over-explained and said the course could run a few hours shorter, one said the practice questions do not match the scenario-based style of the real exam, and one flagged repeated material and typos.

At 31 hours this is a real time commitment, not a weekend cram session, and that is the tradeoff for covering every domain in depth. A couple of reviewers said they paired it with outside material, Professor Messer's videos came up twice, which is worth knowing going in. For most people starting from scratch, it is still a reasonable first and possibly only stop.

Best forAnyone who wants one structured resource to carry them start to finish through Security+.
Skip it ifYou already know networking fundamentals and want a fast, condensed cram instead.

Pros

  • 265 lectures walk through every SY0-701 domain with a downloadable study guide included
  • Quizzes explain wrong answers in detail instead of just flagging them
  • Refreshed this month, so it targets the current exam version, not a retired one
  • Reviewers report first-try passes with scores in the 80s after using it as their main resource

Cons

  • At 31 hours, some reviewers say sections run longer than needed and could be trimmed
  • Practice exam questions don't fully match the scenario-based format of the real test
  • A few reviews mention repeated material, typos, and pop-ups between lessons

Listed for all levels; reviewers with IT experience sometimes found the explanations more detailed than they needed.

What Other Students Are Saying About My CompTIA Security+ Course:

  • Solid information, acronym break downs throughout the course (allows for better note taking). Jason is easy to follow, listen to, and understand during your study period (I sit for hours listening and taking notes and replaying the section) (Mark Guillen, 5 stars)


  • Just passed my security+ today! Dion's course was excellent. It was all I needed, and I took his practice tests I also purchased. The only thing I think would help other testers is more sophisticated and harder performance-based questions as I experienced ones today that were pretty tough and required more hands-on experience. Overall, though completely worth the money. (Duran navarro, 5 stars)


  • The course is very informative and good for people that has no knowledge about cybersecurity so far. It teaches us about the harm caused by attacks and how to prevent them. I would suggest everyone to take this course, even if they don't wan the certificate from Comptia.  (Mahmoud Choumar, 5 stars)


  • Jason is a great pedagogue. He is thorough and amiable. The course has very minimal errors and you can tell he is very strict with the format of his lessons. I had very few questions during the lectures and only experience one issue throughout the whole experience. I will definitely buy more courses from him. I also bought the voucher from his website to get the retake for only 100 bucks! Good job Dion Training! Keep up the great job! (Victor Cabrales, 5 stars)


  • Passed the exam in December of 2022 using this course - FIRST TRY!! This course gave the back bone of everything I needed to pass the Sec. + exam. When the time came to study up a day or two before the actual exam, I used all the practice quizzes/tests from the CompTIA Sec. + study book. Seems thoughtless or stupid to not use the book for actual studying, but I found I learn slightly better in a class environment and this course/videos allowed me that. Thank you for this course and I look forward to many more in the future! Honestly, I haven't taken an ACTUAL exam in years - many years. If I can do it, you all can too! Good luck and God speed! (Nathaniel Shumaker, 5 stars)


Upon completion of this course, you will earn 31 CEUs towards the renewal of your CompTIA A+, Network+, Security+, Linux+, Cloud+, PenTest+, CySA+, or CASP+ certifications.

Thanks Dion Training team! The course and joint practice exams 1 and 2 were invaluable to my success on the certification exam. I passed with a score of 785. I would highly recommend it to anyone seeking comprehensive preparation for the Sec+ exam, and I would also recommend Professor Messer's Sec+ YouTube playlist videos.

By Brandon Hawksley on 8/25/2026

I just passed this security + on my first try using this course and purchasing the 6 practice exams. I got 70% on the first exam, 75% on the next, and then was consistently getting 80-85% on the final few. I would recommend to anyone reading to make flashcards on all the questions/topics you are unsure of through the practice exams and keep taking on new ones once you have revised those questions you got wrong. Additionally, it is useful to look through the actual objectives for security + to see if there is anything you are unsure of and make flashcards on those as well. Thank you very much for helping me pass!

By Oliver Pendrill on 8/20/2026

I've used these Dion Training courses for both this exam and the Network+ exam now and it's comfortably got me through both of them with scores of 85% and 90% respectively. The bulk of my studies have been these resources so I cannot recommend them enough for anyone else seeking these certifications.

By Swati Chauhan on 8/12/2026

Hi Dion Training Team, I recently completed the CompTIA Security+ (SY0-701) Complete Course on Udemy and wanted to reach out and say thank you! The course material was well-structured and extremely helpful. I really appreciated the downloadable study guides and the detailed practice test questions. Thanks again for such a great course!

By Matt Russo on 7/20/2026

Yes, it is a good match for me. I want to enter the cybersecurity field as an adjacent career to my 35 years of experience in technical support. Cybersecurity is also a rapidly growing field that I believe is relatively resistant to AI displacement, making it a strong long-term career move for me.

By Lindsay Brown on 7/15/2026

I really enjoy the detail courses. I have been studying for the security + exam for a month, however it wasn't until i started this course, did I feel like I was understanding the material. I'm finally understanding the material better. I feel a lot better and more prepared for the security + exam, this course is worth taking to get the best knowledge, and be test ready.

By Sameer Mohammed on 5/30/2026

I like jason he is a very good speaker/instructor but the other instructor might be good but I personally didnt liked the way he teaches /speak or might be his accent which I felt not satisfactory, I Iost the concentration in his toipcs, apologies for this comment if it sound rude, if there is only jason's full course please let us know, would be very happy to take it.

By Finn Robin Schniebel on 5/27/2026

Most of the course is very good but some content like where audits and assessments are different or overlap could be better explained. The fact that the quizzes and practice exam don't have more questions when retaking is a real shame since that would make it so much easier to study and find places I struggle at. I like that the course gives extra info about the field and does not just cover the exact parts that are on the exam but it would be great if there was some separation in either the study guide or the lessons to tell you what is important for the exam and what is extra info.

By Nizaiah Chavis on 5/26/2026

I passed the Sec+ exam after about a month-ish of study and I wasn't very consistent. The material is great and they go over what you need to know. I will admit, the lectures can get really into weeds on a lot of topics, but I recognize they go above and beyond on the examples to ensure that you understand the concepts. Otherwise, despite nitpicking some of the delivery, these guys clearly know what they're talking about, and the content is sufficient for passing the exam. I took this course and the 6 practice tests from another bundle they have. Thanks for the work y'all put into the course!

By Ebenezer Danquah on 5/20/2026

I enjoyed every module, even the really long ones. These instructors are very knowledgeable and detailed and made everything easy to understand. The practice exams were very helpful in preparing to take the exam. I passed my exam and I have this course and its instructors to thank!
