It's never too late! I started at 24, I'm 28 now. Your not much older than one of my peer-turned-dear-friends. Truth is that as long as you nail the learning the rest will just be a matter of time. It took me almost a year of job hunting to get this gig, but it's municipal government work in a union in Canada.

I'll warn you however that cybersecurity isn't entry level stuff. I'd been working as a whatever-they-want-me-to-do solo IT guy for two years for a college before I made the transition. For what it's worth I was also customer service and you can definitely leverage that when looking at the (very crowded) entry level IT market of helpdesk roles. Helpdesk sucks, but unlike retail the suck doesn't last forever. Do a year, study certs while you do, then get out. Never. Stop. Applying.

I recommend looking into the compTIA certifications like A+, Networking+, and naturally Security+. Those are good fundamentals to have down, and combined with classes you shouldn't have too hard a time.

Hope this helps a bit.

It's not. Simple reality is your going to end up in help desk (you might end up in a SNOC or related but ultimately I'd advise help desk just so you learn some real world ops). Security, like it's engineering counterparts is not something you can do with zero experience in the industry. The two hardest job interviews you will ever have in the general it industry are getting into help desk, and getting out of help desk.
