Need help with stepping into ethical hacking

I am a CSE graduate working at a company that is a major player in technology. I was interested in ethical hacking earlier, but I didn’t pursue it because I received and accepted a seven‑figure offer (Rs). I currently work on a mission‑critical middleware and have gained broad—but not deep—exposure to many CS concepts. I now plan to return to ethical hacking and need to revisit operating systems and networking. I’ve seen several videos mentioning CompTIA, so I’m asking those of you who are using it for a roadmap, any tips from your experience, and whether CompTIA is worthwhile for someone with my background.

Thank you.
