About Sagarika S

Information Security Engineer with around 6 years of experience securing financial and regulated environments through hands-on ownership of security infrastructure, threat detection, and vulnerability management. I work across Linux, Unix, macOS, and Windows systems, operating and tuning SIEM, EDR, firewall, and network security platforms to improve detection quality, reduce alert noise, and ensure telemetry integrity. I investigate high-severity incidents, support penetration testing and remediation efforts, and drive vulnerability lifecycle management using risk-based prioritization. I collaborate closely with engineering teams to embed security into infrastructure and DevOps workflows while maintaining audit-ready documentation and reporting. I thrive in high-paced environments where security must be strong, measurable, and aligned with business execution.

Experience

1. Senior Information Technology Engineer

   Rocket Money

   Jul 2023 — Present

   At Rocket Money, I supported the security of a fast-moving financial platform where stability and low latency were critical. I worked closely with endpoint, network, and engineering teams to keep our detection systems healthy and reliable. My daily work included tuning SIEM and EDR platforms, validating log ingestion, reviewing firewall and segmentation changes, and investigating alerts across Linux, Unix, macOS, and Windows systems. I focused heavily on improving detection quality by reducing noise and validating rule behavior through testing and replay checks. I also managed vulnerability remediation cycles, supported penetration testing efforts, and ensured audit evidence was complete and defensible. The role required balancing strong security controls with business continuity, and I took pride in building processes that were both thorough and practical.
