About Tapas Choudhury

As a Senior Consultant at Deloitte with over 10 years of experience in cybersecurity, I specialize in SIEM deployment, Splunk data onboarding, and threat detection strategies. My work involves leading end-to-end onboarding initiatives, overseeing Splunk environment configurations, and conducting content gap analyses to strengthen organizational security frameworks. I focus on enabling real-time threat visibility by designing tailored dashboards and operationalizing use cases that address critical security needs. Previously, I managed SIEM deployments and SOC operations at Ericsson, enhancing monitoring capabilities for a major telecom client. Collaborating with cross-functional teams, I contributed to closing cybersecurity gaps with actionable solutions. My mission is to empower organizations to mitigate risks, adopt robust security practices, and achieve operational resilience in an evolving threat landscape.
