Cybersecurity and AI Excites me !!!!
I am Prabhu Perumal — a Cybersecurity and DevSecOps engineer currently in the USA. I have spent my career protecting real financial organizations from real threats — fixing vulnerabilities, securing cloud systems, stopping data leaks and making sure attackers have a very bad day. I studied Computer Science in India and later pursued my Master's in Cybersecurity in the USA. I don't just work in cybersecurity; I think and write about it, break things intentionally to understand them, and build projects to test what I have learned. This blog is where the professional and the curious side of me meet , no corporate language, just honest learning shared openly.
