B.Pharm is a good course to study. There are a good need to the students pursuing the course in the industries. So you can pursue that but the starting salaries are low which I would say will be lesser than that of starting package as a BTech CSE (Cyber Security) course.

Now if you want to study cyber security along side with your B.Pharm then I would recommend you to go for online courses which can be beneficial as this course is more about knowledge and less about the degree.

I hope you get my point. All the very best for your future endeavors!
