Course Description

Did you know that almost 50% of employees transfer business files to a private laptop? Is there anything we can do about it? Yes - implement a Data Loss Prevention (DLP) system to address potential data loss or theft on Windows, Mac OS X, Linux, and mobile devices. Protect your sensitive files, clients' information, credit card numbers, and more.

With a DLP system you decide when, from where, and by whom data can or cannot be accessed and copied! 

About this course: This is a vendor-neutral introductory course providing a high-level overview of DLP systems, architecture, components, and features. Hands-on labs included!

What I will learn: How to start with a DLP system, create a basic policy, understand DLP components, and even create your first regular expression (regex).

Special topics: Even though this is a vendor-neutral course, I show you a lot of real world examples and DLP systems that you can try at home - for free!

Join this course to learn:

  • Data Loss Prevention (DLP) architecture

  • Endpoint vs Network protection

  • Data at rest, Data in motion, Data in use

  • Deploy your own DLP system in minutes using a virtual machine

  • See a lot of examples and real world applications (e.g. blocking uploads, sharing programming codes)

  • Write your first regular expression

  • Learn about more advanced DLP features (SSL interception, OCR, integration with Active Directory)

  • See a lot of real world examples and practical tips

  • You will know enough to understand how DLP protects your network

Join now and see what a DLP system can do for you and your company! Protect USB drives, clipboard, network drives, email clients, Skype, and more. Make sure nobody can share or copy your internal files and data ever again.

This is a vendor-neutral course that will make you ready to start with any DLP system, including enterprise solutions from Symantec or McAfee. Hands-on labs are based on two DLP systems: DeviceLock and EndpointProtector. A real-world course.

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.
