CertFirst Trainer delivered a great course. I have taken a couple of certification prep courses offered by the Marine Corps and this one takes the cake. The material was presented in an easy to follow and understand manner. It was very entertaining. In my Marine Corps courses the instructor would simple read from the book or from power point slides. This course was quite the opposite. CertFirst Trainer presented an immersive experience with the videos, resources, and his sheer wealth of knowledge.

I had the pleasure of Kris administering the CompTIA Security+ / Network+ boot camp in 2019. The class and material provided was critical to my achieving the Security + certification. I also found the Security + course work and material highly correlated to the CISSP course. He does a great job going beyond the basic material and test prep by providing practical application and demonstrations. I absolutely had no issues whatsoever with CertFirst support team. All obligations were met to expectation of quality in a timely manner. Includes deliveries of exam prep tools, study material, and virtual class related correspondence.

Thank you Sam and CertFirst for delivering a great 1 on 1class on a short notice. I was going to loose my job if I did not pass my exam before the deadline given to me. All the support I received from the CertFirst team and excellent Virtual live instruction from Sam during these COVID crisis, I was able to pass the exam at my first attempt. Thank you so much CertFirst as I cant be more satisfied and will recommend you guys to all my friends.

Trainer was very effective in teaching the lessons and provided an assortment of additional resources to not only help acquire practical and conceptual knowledge of the subject matter, but also allow the students a better chance to pass the CISSP exam. Also what a stellar support team at CertFirst.

A lot of information was presented in a digestible way. I received more training materials than I expected (I expected maybe one or two files, but I got a ton of material to help me study, files upon files), plus easy to understand slides, and helpful/funny/fun videos to help break up the monotony. The instructor threw in a lot of humor and seemed down to earth, didn't judge me for any questions I asked no matter how simple, gave me praise for asking good questions. I highly recommend CertFirst for the CompTIA training.

I enjoyed how CertFirst Trainer was able to bring in additional media to the training, instead of just lecturing to slides. He provided demonstrations of the technologies we discussed, showed simulations of networks to explain things, and also used videos from various companies and industry experts to further explain topics. I also appreciated his sense of humor to keep things from being too dry. Trainer did a good job balancing the compressed schedule that we had due to a holiday and has made sure to provide contact information should I have any additional questions.

This is the best interaction that I had with a Training company representative and it is because of Parm. He guided me beyond my expectations and that gave me the confidence to sign-up a course. Thanks a lot to Parm for this opportunity. The Instructor Kris has put all his resources and efforts under his belt to guide and expose me to the cybersecurity world with relevant knowledge and all his guidance is appreciated. I would take another training with CertFirst if an opportunity arises and recommend him to others too. I couldn't think of anything else and more from both Kris and Parm and they are many steps ahead to support me. Thanks

Kris was a great instructor, and did a good job at keeping student's attention. There was a lot of material to cover in the 5 days of training, but Kris did a good job of getting through everything. -Bryan Sonia is extremely helpful, professional, and accommodating. This is the second class I have attend with your company. I have plans to sign up myself and my IT Staff for more classes with your company. The Instructor was extremely knowledgeable and seemed very passionate teaching and providing examples and additional materials; he kept the four days very interesting as he kept me engaged and interested in the subject. I absolutely enjoyed his style of teaching and I look forward to taking another class from him. -Tam

Great course. I am looking forward to taking more CISSP and cloud classes with CertFirsts in the near future. -Gil


Instructor did a fantastic job covering all the CompTIA course material. He was knowledgeable and able to explain the material in a manner that related to the students. I really enjoyed this class. -Adam I thought this course was very good. It was fast-paced due to combining the two classes into one week (network+ and Security+), but it's a manageable amount of content. Thank you. -Kathy The Instructor was able to cover all the Topics listed in the Course Outline and he was able to provide us with all the details and resources related to this training. Thank you for an excellent training session. -Candy
