About Sudhir

I’m Sudhir, a CISSP-certified Information Security Analyst based in Mumbai, India.

At Infosys, I work on enterprise network security, compliance, vulnerability management, and security operations across large-scale environments. My focus areas include firewall policy hygiene, network hardening, control validation, and security posture improvement using tools such as Skybox, AlgoSec, Qualys, and CyberArk.

This site is where I write about practical cybersecurity, security architecture, compliance, security tools, and lessons from real-world defensive work.
