Anyone learning security in the capital should know about the combined OWASP Delhi and null Delhi meetups. The chapters have run mostly monthly sessions across Delhi, Noida and Gurgaon, and they are free and open to anyone curious about information security. Talks range from web application bugs to new attack research, and newcomers are welcome.
If your online course covers penetration testing or SOC work, attending regularly gives you a running check on whether the labs match what practitioners are seeing. It also helps with the job search, because people at these meetings often know which teams across NCR are hiring juniors. Once you have written up a small finding or tool of your own, offer a short slot. Presenting even once gets you noticed faster than months of quiet attendance.
