What Other Students Are Saying About Our Courses:
Everything was well explained and informative. Was nice that it included some of the more important material to help review instead of just leaving the previous certification information as all "assumed knowledge" and passing the buck. As always, these courses continue to be the best training I have used so far. (Jonathan B., 5 stars)
I have been in the industry for between 5 and 10 years, and needed a refresher on several of these topics before taking the exam. Course is designed well, so you can focus on those areas that you need to, while listening to the others in the background as a refresher for the others. (Jamie R., 5 stars)
I would recommend it to anyone aspiring to complete your examinations at the end, I completed the course and successfully passed my exams on the first attempt (Bankole K., 5 stars)
Upon completion of this course, you will earn 46 CEUs towards the renewal of your CompTIA Tech+, A+, Network+, Security+, Linux+, Cloud+, PenTest+, CySA+, or CASP+ certifications.

I went through the full Dion Training SecurityX course and it was exactly what I needed. The instructor explains complex topics (Zero Trust, attack surfaces, cryptography updates, and threat modeling) in a clear, practical way without unnecessary fluff. The practice exams were spot-on for the real test difficulty. If you're coming from Security+ or looking to level up, this course will get you there. Highly recommend — worth every penny. Would definitely take another course from this instructor. — Mike C., July 2026

I passed my securityX today! I only used this Dion course and the additional practice tests. Despite my virtual machine freezing on me mid exam, I still was able to pass without it due to how well the practice tests prepared me! I will be using Dion for my CISSP next ! Thank you :) PS this course does not prepare u for simulations so make sure u practice on a home lab if u are not experienced or comfortable
By John Agyarko on 6/23/2026
Well structured content. More performance/ practice base content to enhance our learning experience will be appreciated. I passed the exams today using only this resource. Same for their Security+, CySA+, and Pentest +, all withing 2 years of using just their learning resource. SecurityAI is next!!

Proud to share that I’ve officially earned the “CompTIA SecurityX” (CAS-005) certification formerly known as CASP+ This was a challenging but very rewarding experience. Preparing for SecurityX pushed me to go beyond just studying concepts and really think like a security professional — from enterprise security architecture to risk management and real-world incident scenarios. A special thank you to Jason Dion and Jeremiah Minner, M.S., SecurityX, CEH at Dion Training for the high quality training resources. Your Udemy training Videos and Practice questions are the only resource i used to prepare for the exam. I Passed the SecurityX CAS-005 Exam on the 5th of May, 2026

It is clear and easy to understand and the format in which it is set up is also easy. The process of providing an overview at the beginning of the topic, then going into details and doing a final overview is very beneficial .
By Damian Griffiths on 4/2/2026
After passing Network+, CySA+ and PenTest+, I thought I had a comprehensive grasp on networking and security considerations. Instead I had a solid foundation to take this considerably more advanced course, which contains a huge amount of well explained information. I imagine the exam will not be easy but I am enjoying the studying and feel I will be ready when I take it.
By Jose Figueroa on 1/23/2026
Very detailed instructions, the instructor made things simple and easy to understand by associating the lesson with everyday thing. I would recommend this to anyone looking to pass the security X exam
By Tina Dalton on 1/19/2026
This is the first course that I've taken where encryption/hashing has been explained that I understand. Although I'm only calling out this area specifically, I think the instructor has a gift for explaining/teaching where a majority of people can understand the material. And, confidently take the Security X certification.
By Kris Vandermark on 12/14/2025
Lots of spelling/grammar errors on slides. I saw a few low-effort AI graphics that don't make any sense. Training material appears to be just CAS-004/CASP+ material with SecurityX slapped on it, will definitely recommend people to look at other resources.
By Don Cortell on 11/26/2025
A huge thank you to Jeremiah Minner for his exceptional teaching style! His detailed explanations and real-world examples made complex topics easy to understand. The way he presented such a copious amount of information in a clear, structured manner was impressive and incredibly helpful. Jeremiah’s approach kept me engaged throughout the course, and his ability to break down challenging concepts gave me the confidence I needed. Thanks to this course and his guidance, I passed the certification exam on my first attempt! If you’re preparing for SecurityX, I highly recommend this course. It’s comprehensive, well-organized, and taught by an instructor who truly cares about helping students succeed.
