What credentials do I need to break into cybersecurty as an analyst?

I have been in IT for over 25 years as a mainframe developer, then web application developer, development lead and IT Manager. I am interested in breaking into cybersecurity (pun intended). I am trying to pursue some online trainings to facilitate the career change. For example right now I am taking the IBM Information Security Analyst certification course. I intend to take others as well. But how much training like this is enough to obtain an analyst job? I don’t want to go back for another degree, if possible.
