The course is good with practicals, however instead of seeing it would have been better to update with working trials, if available. Do add the links under resources section for easy click and refer.
By Subramanian Narayanan on 11/14/2025
Fantastic course. with all the necessary fundamentals covered. However there can be more topics on AI Based DLP and also few use-cases/case studies on DLP will make it exceptional topics
By Luke Andrew E. Alfaro on 6/25/2024
The contents in this course are very relevant to learn about DLP. It was discussed in a way that is easy to understand with the appropriate visuals and the resources are excellent supplemental information. Happy with what I've learned and cheers to Marious for such a great course.
By Anonymized User on 8/20/2023
This course is well designed for Beginners, however, I would like you to come up with more deep technical analysis on how the DLP engine works. something more on regex and deep inspection.
By Anonymized User on 5/4/2022
Good range of content and covered a high level view of the topic as described. Only thing I would add is a 'next step'. A course or resource that would be recommended to dive deeper into the topic.
By Don Santana on 3/19/2019
The instructor (Marious) is very knowledgeable. His instructions are very easy to understand and follow along. This is a great intermediate to upper level course for someone who would like to learn more about DLP.
By JP Quinn on 12/11/2018
I enjoyed the primer I got out of this course, and would take more of his courses in the future, hopefully he'll come out with more advanced and deeper in depth topics and courses
By Olufemi Afolabi on 11/21/2018
So far I understood what is DLP, tools for DLP and different ways for data prevention; the course is a little bit advanced for me I will need more explanation on how to configure DLP tools and Regex. Thank you for providing links for more reseach on DLP
By Saumya Bhardwaj on 10/23/2018
course is useful for beginners. if you are going to work on any vendor specific DLP, then it is useful to get basic knowledge from this course. It helped me to understand DLP basics. But it is just as step 0 to work on DLP , longer way to read and learn before starting working on vendor specific DLP.
By Aleksandr Skripnikov on 9/3/2018
I was expecting much much more, but this is my problem... In Channels section - missing Cloud Services, Mobile Services... In DLP deployment architecture - missing Discovery (Data Discovery, Classification), Cloud Services... Presentations is mostly consists of slides and screenshots, but basics of regex have some live demo via other sites. In DLP in action or Bonus section - no actual steps/advises on how to install mentioned in course Endpoint DLP solutions (Enterprise Encryptor and DeviceLock). Bonus section - missing Active Directory installation instructions and actual integration of DeviceLock settings in GPO. So besides practice with regex (still additional materials needed for more info and practical usage) - students cannot actually practice anything else.
