Bhubaneswar's security community is small and close-knit. OWASP Bhubaneswar and null Bhubaneswar often run combined monthly meets, with talks on bug bounty, reverse engineering and general infosec, and some sessions have been held online. The OWASP chapter also aims to represent the wider Odisha infosec community.
If you are studying ethical hacking or networking online from Bhubaneswar, these meets are where you can try out what you have learned. Bring a writeup of a lab or a capture the flag challenge you solved and ask for comments. Over a few months you will get to know the regulars, and that often leads to a mentor or a referral.
Independent community groups, listed for reference. They are not run by or affiliated with WebAsha.
