QA career path change

I have been in QA for more than 5 years now. Work as a Senior software QA. I have been thinking of changing my career path, without investing a lot of time and money. Full fledged automation is an option. ETL Development is another. But I am more geared towards Cyber Security/ Security Testing/Analyst. Is it a viable approach? Can I get a job in this area without getting very expensive certifications? What can you guys suggest that I should do for a career move.

Thanks
