At Cancer Treatment Services India Private Limited (Siemens Healthineers), I harden Microsoft 365, Entra ID, and CrowdStrike Falcon environments for enterprise healthcare. I raised the Microsoft Secure Score from 40% to 89% through systematic risk remediation.
I manage endpoint protection across 2,000+ endpoints, onboarded 35+ Sophos firewalls for centralized monitoring, and built PowerShell and API-driven runbooks connecting Falcon alerts with Microsoft 365 Exchange. My work automates containment and phishing quarantine to reduce response time.
I also investigate live account-takeover, brute-force, and domain-spoofing incidents; enforce Conditional Access, geo-blocking, SPF/DKIM/DMARC, and Purview DLP controls; and run phishing simulations backed by 20+ custom LMS modules.
