Gogulnath Kulothungan

I am currently pursuing a Master's degree in Information Systems at Cleveland State University. This program equips me with advanced skills in database management, cybersecurity, business intelligence, and IT project management. I am gaining practical experience to effectively design and manage information systems that drive organizational success. I am eager to apply my knowledge to contribute to the evolving field of Information Systems.

"I specialize in securing cloud platforms by proactively identifying and mitigating cyber threats. My role involves continuous monitoring, analyzing server logs, and addressing vulnerabilities to ensure a robust security posture. Cybersecurity is a dynamic field, requiring constant vigilance and adaptation, and I take pride in safeguarding critical data and systems. While some may see it as a challenge, I view it as an opportunity to enhance security frameworks and stay ahead of emerging threats."

With over 4 years of progressive experience in cybersecurity, data protection, and enterprise infrastructure security, I bring a proven track record of safeguarding mission-critical systems and enabling secure digital operations across hybrid and multi-cloud environments. My expertise lies in end-to-end threat management, secure data backup, vulnerability remediation, SIEM optimization, and compliance enforcement, making me a versatile asset in both defensive and recovery-focused security operations.

🔧 Security Analyst – Valeo (2023–2024)

At Valeo, I led and executed proactive security operations across endpoint, network, and cloud layers. I utilized Qualys for continuous vulnerability scanning and spearheaded patching coordination efforts, successfully reducing critical unpatched vulnerabilities by 45% within a single quarter. As part of the incident detection and response team, I managed Cortex XDR and Fortinet SIEM, enhancing MTTD and MTTR by over 25% through improved threat triage and malware investigation.

I deployed Thales CipherTrust encryption to secure data at rest and ensured full compliance with GDPR and NIST frameworks, achieving 100% encryption of sensitive workloads. I also architected and maintained FortiGate firewalls and UTM appliances via centralized FortiManager, reducing unauthorized access attempts by 40% and driving enhanced network visibility and policy consistency.

In backup operations, I engineered high-resiliency workflows using Commvault Media Agents for tape, disk, and cloud (AWS S3) targets. I achieved a 99.9% backup success rate, with zero data loss incidents, while generating SLA-based reports and dashboards that improved compliance insights and executive-level reporting. I was also instrumental in Red Team penetration testing and Blue Team SIEM tuning, identifying and closing 12+ high-risk vulnerabilities, substantially strengthening the organization’s threat detection capabilities.

🛡️ Data Protection Engineer – Tata Consultancy Services (2020–2023)

At TCS, I served as the lead engineer for one of the largest Commvault migrations, transitioning 6,000+ servers from IBM TSM to Commvault without disrupting business continuity. This effort modernized the backup infrastructure and introduced multi-cloud backup pipelines across AWS, Azure, and GCP, incorporating IAM controls and encryption protocols for enhanced data confidentiality and integrity.

I enforced NIST/GDPR-aligned retention policies that supported long-term regulatory compliance and business continuity while optimizing deduplication strategies and media agent performance to cut storage costs and improve throughput. I also supported application-aware backups for complex systems including SAP HANA, Oracle, DB2, and Domino, ensuring consistent and recoverable snapshots for enterprise applications.

I implemented disaster recovery (DR) frameworks that improved RTO/RPO alignment and enabled rapid recovery across hybrid environments. Additionally, I designed automated SLA dashboards, mentored junior engineers in Commvault operations, and created audit-ready documentation that streamlined compliance and stakeholder reporting.

I have worked on diverse projects spanning cybersecurity, blockchain, and database management. In my Blockchain-Based Money Transactions project, I developed a Solidity smart contract for secure peer-to-peer transactions on Ethereum, integrating Metamask API for transaction handling and EtherScan for real-time auditing, ensuring transparency and data integrity. In Enterprise Database Management, I designed relational schemas, optimized SQL queries, and developed Python automation scripts for efficient data storage, retrieval, and processing. Additionally, through the Commonwealth Bank Cybersecurity Job Simulation, I built fraud detection dashboards using Splunk, conducted penetration testing on web applications, identified vulnerabilities, and implemented remediation strategies to strengthen security defenses.

I have worked on diverse, interdisciplinary projects that span across cybersecurity, blockchain development, and enterprise database management—leveraging a mix of emerging technologies, security frameworks, and automation.

🔗 Blockchain-Based Money Transactions
