The overall experience of learning Tableau was excellent as the faculty was very knowledgeable & supportive till the very end. Even during the session she gave attention to each & every learner & helped them clarify their doubts at the same point. I would recommend this faculty to be provided for other modules also, so that we learners have a better understanding of other modules like SQL, Python etc. too. Read less

Excellent in terms of content covered and ease of understanding. The series of lectures as well as the projects/tutorials were very informative in understanding the topics covered. THe instructor was clear and concise with his delivery of course contents and was engaging during the lectures. Read less

I had a very constructive and efficient training, led by the trainer: Sarvesh Kumar, facilitated by Simplilearn. 
I was able to understand and even appreciate the architecture behind the distributed systems by large while appreciating the Hadoop ecosystem. 
With this I was able to relate the abstraction given by newer technologies, because the underlying concepts were made transparent and easy to assimilate.
The teaching flow, the type of instruction modes, working sessions and engaging methods were all 10/10 by Sarvesh Kumar. He was able to achieve this even while staying very comprehensive and able to shed deep insights into each component of the Hadoop and Spark Ecosystem. While doing so he also covered some external topics within basic linux , Python and Java, that would support in this learning journey of Hadoop. I also thank Simplilearn to support extended sessions in this process. Can I ask for more? :) Read less

Taking this course with Ranjan Raja was a game-changer. Their teaching on building a hacker mindset and learning how to defend against future attacks wasn’t just educational—it was transformational.What sets Ranjan Raja apart is their ability to break down complex cybersecurity concepts into practical, real-world scenarios. He didn’t just teach tools and techniques—He cultivated a mindset. You learn how hackers think, where vulnerabilities lie, and most importantly, how to outsmart them before they strike.
The lessons were engaging, hands-on, and filled with relevant examples that made every topic stick. I walked away not only with a better technical foundation but with a whole new way of looking at cybersecurity challenges—proactively and creatively.If you're serious about security, threat modeling, or just staying ahead in an ever-evolving tech world, this instructor is one of the best you could learn from.
Highly recommended! Read less

ALot of informations. Very nice session. All the cources i have done are the best. Thanks Simplilearn Teachers and team. I was a bit unsure for the online learning. But the teachers are so good and they explain all the things with the examples and with the daily life examples. It really is very helpfull. The syllabus is also selected very carefully Read less

I recently completed the "PG CS - Build a Hacker Mindset and Defend Against Future Attacks" course under the guidance of Ranjan Raja, and I must say, it was an exceptional learning experience. As someone passionate about cybersecurity, this course not only met but exceeded my expectations, thanks largely to the expertise and dedication of our trainer, Ranjan Raja.
Ranjan's depth of knowledge in cybersecurity is truly impressive. His ability to break down complex topics such as ethical hacking, network security, and vulnerability assessment into digestible concepts made the course accessible even for beginners. He has a clear mastery of the subject matter, which he demonstrated through real-world examples and case studies that were both engaging and relevant. His hands-on approach to teaching tools like Metasploit, Wireshark, and Nmap was particularly helpful in bridging the gap between theory and practice. 

Ranjan’s teaching style is dynamic and interactive. He encourages questions and discussions, creating an open and collaborative learning environment. Whether it was during live sessions or Q&A segments, he always took the time to ensure every student understood the material. His enthusiasm for cybersecurity is contagious, and he has a unique way of making even the most technical topics interesting and relatable.


One of the standout features of this course was its focus on practical application. Ranjan emphasized the importance of developing a "hacker mindset" by guiding us through simulated cyberattacks and defense strategies. The labs and projects were meticulously designed to mimic real-world scenarios, giving us invaluable hands-on experience. This practical approach has significantly boosted my confidence in identifying vulnerabilities and implementing robust security measures.


Beyond his role as a trainer, Ranjan acted as a mentor throughout the course. He provided personalized feedback on assignments and went above and beyond to ensure that no student was left behind. His willingness to share additional resources and industry insights demonstrates his commitment to helping students succeed not just in the course but also in their future careers.


This course has fundamentally transformed the way I think about cybersecurity. Under Ranjan’s guidance, I’ve learned to anticipate potential threats, think like an attacker, and proactively defend against them. The skills I’ve acquired are directly applicable to my professional goals, and I feel better equipped to contribute meaningfully to the field of cybersecurity.


In conclusion, Ranjan Raja is an outstanding trainer whose passion, expertise, and dedication make him one of the best educators I’ve had the privilege to learn from. If you’re considering enrolling in this course, I highly recommend it—especially with Ranjan at the helm. You’ll leave the program not only with a solid understanding of cybersecurity principles but also with the critical thinking skills needed to stay ahead in this ever-evolving field.



Thank you, Ranjan, for an unforgettable learning journey!

 The course takes you from the very basics Numpy, Pandas, all the way to data visualization with Matplotlib, Pyplot, etc. 
 It’s beginner-friendly, yet still dives deep into real-world analytics use cases. 

 The online classes and recorded content was also very well-paced and easy to follow. 

 What Could Be Improved: 
 While tools like powerbi are used, you need to provide learning for that.
 It would’ve been nice to have more discussion forums or peer reviews for projects to exchange feedback. 
 Resume and LinkedIn profile reviews need to be done regularly so we can build our resume. Read less

So far, the course has been exceptionally well-structured and thoughtfully organized. The instructor has done a great job of laying out the material in a clear and logical manner, making it easy to follow along and stay engaged. Each topic is introduced with just the right amount of background, followed by a gradual deep dive that never feels overwhelming. One of the standout aspects of the course is the clarity with which the instructor explains even complex concepts. The use of simple language, visual aids, and relatable analogies helps reinforce understanding, making it suitable for both beginners and those with some prior knowledge.Additionally, the instructor includes plenty of practical examples throughout the course. These examples are not only relevant to the topics being taught, but they also demonstrate how the concepts apply in real-world scenarios. This hands-on approach helps bridge the gap between theory and practice, which is incredibly valuable for learners.The pacing of the course is another strong point. It moves steadily without rushing, allowing ample time to absorb each concept. Overall, the instructor's teaching style, combined with a well-organized curriculum and strong examples, makes this course both informative and enjoyable. I'm looking forward to continuing and learning more. Read less

1. The instructor, Kuldeep is very well versed with the topics and the teaching material covers good variety of topics. 
2.The Master Class given by the IITK Professors is not about the topic that is being covered in the learning sessions. I hope they are aligned with what topic is being taught in the class, and be more interactive.  Read less

Course is good with good flow.
Trainer is explaining from basics. 
Recorded sessions and code of each day helps.
We need more master class sessions on weekends else on weekdays it's difficult to attend.
More real world examples required and some extra Lab sessions are required.

All going pretty good. Thanks. Read less

To be honest the candidate are not at the same level. Instructor was ok but the candidates enrolled for this course are not at same level. Perhaps some batching of students should have been done based on segmentation. The person whom we spoke at the begining of the course did not provide the details Read less
