Laxmi Sarat Chandra Nunnaguppala is a self-motivated Security Architect and Implementation Engineer with over 9 years of expertise in SIEM technologies. I excel in planning, designing, customizing, and integrating SIEM solutions for robust security infrastructures.
My certifications as SIEM Architect and Accredited Enterprise Security professional demonstrate my commitment to industry best practices and ensuring consistent, secure development. I have a proven track record of developing performance metrics and reports to optimize security operations.
Throughout my career, I’ve successfully delivered SIEM and cybersecurity services to a diverse clientele exceeding 40 organizations, including industry leaders like Horizon BCBS, NASDAQ, Rockstar Games, Pine Bridge Investments, DTCC, DOMO, AAA, Churchill Downs, Brown-Forman, KFB, Fidelity, Ingram Inc, Meridian Health, Bay State Health, Southern Company, Equifax, Erie Insurance, TIAA, etc. My skills extend beyond technical expertise; I possess excellent communication and analytical abilities, and I thrive in fast-paced environments, effectively managing multiple tasks and collaborating with various teams.
Designed a custom application for a bank client that leverages machine learning to monitor the health of security data logs. This intelligent tool can distinguish between peak traffic periods (e.g., holidays, weekdays) and adjust alerts accordingly, minimizing false positives. The application further utilizes a standard deviation model to identify significant changes in log volume, potentially indicating security incidents.
My contributions were instrumental in Roundtower Technologies (AHEAD) receiving the Americas Rookie Partner of the Year award in 2018.
I possess extensive experience in designing and implementing secure logging solutions for SIEM tools. My approach prioritizes high availability (HA) and disaster recovery (DR), ensuring continuous operation and data protection aligned with customer needs. My expertise extends to implementing and maintaining PCI and HIPAA compliance standards across diverse organizations, guaranteeing data security adheres to industry regulations.
Further strengthening client security and compliance, I’ve conducted health checks on SIEM platforms for over 40 clients across banking, finance, healthcare, and gaming sectors. This proactive approach identified and mitigated potential security risks, fostering robust security postures.
My passion for innovation led me to author research articles published in prestigious journals like the International Journal for Innovative Engineering and Management Research. These articles explored critical topics like achieving PCI compliance within CRM systems and building trust through integrated security and customer relationship management.

This combination of experience, certifications, and academic contributions demonstrates my commitment to delivering secure and innovative SIEM solutions.
My approach to security prioritizes efficiency and innovation. At Equifax, I spearheaded the consolidation of five disparate SIEM platforms, streamlining security management and ensuring PCI compliance across multiple departments. This initiative not only centralized security operations but also automated patch deployment and system rebuilds, minimizing security vulnerabilities.
Furthermore, I possess extensive experience in designing and migrating enterprise-level SIEM platforms for multiple Fortune 500 companies. This translates to a proven track record of delivering cutting-edge cybersecurity solutions tailored to meet the specific needs of large organizations.

Reduced Alert Fatigue: These tools facilitated an impressive 80% reduction in alert volume, significantly minimizing “alert fatigue” for security personnel.
Enhanced Efficiency: By streamlining alerts, the solution freed up 75% of employee time previously spent investigating false positives. This translates to substantial cost savings.
Improved Project Management: The combined impact of reduced alert volume and increased employee efficiency resulted in a 55% decrease in project management costs. This signifies a significant improvement in overall project delivery efficiency.
Looking towards the future of security, my research delves into cloud-based SIEM systems. One article explores the integration of AI and machine learning for building secure and scalable cloud-based SIEM architectures. Another examines the implementation of DevSecOps practices to achieve continuous threat detection and response within cloud environments.
These published works, coupled with my experience in large-scale SIEM deployments, demonstrate my commitment to developing innovative strategies that optimize security operations and empower organizations to stay ahead of evolving threats.
