Welcome to EHnet
Could you please provide some more details about yourself i.e the skill set you have, experience level etc. So that you can get more specific answer.
There are a lot of CEH institutes in Bangalore, but from my personal experience they don't worth the price. last time I checked(a year back) CEH training in Bangalore was around 25K INR but if you spare 6K INR more you can go for eCPPT or with 11K more you can go for OSCP, which in my opinion are far better courses with a high learning curve. Having CEH alone doesn't land you in a job(which is same case with any beginner level certification).
What certification you want to go for or what you want to learn, it entirely depends on what skill set you have, what you are interested in and what you are expecting.
