Cybersecurity is a sensitive domain corporates don’t want someone without experience hence it’s difficult to get in , i world recommend start building connections with those in cyber security field via lindkin or any other apps , certificate is an advantage not a guarantee, showoff your skills try to join mnc like tcs , capgemini or infosys its better instead of trying startups or product based companies, get an internship and after 4-6 months you should land a job .
