Experience
Security Analyst
Jan 2026 — PresentNTT Managed Services India Private Limited / India
- Monitored multiple distributed enterprise client environments using Palo Alto SIEM and Microsoft Sentinel solutions.
- Performed continuous real-time security event monitoring, alert triage, and high-fidelity validation to isolate true security
- incidents.
- Investigated critical security alerts via deep-dive analysis of event logs, network traffic, endpoint telemetry, and threat
- intelligence feeds.
- Managed security incident lifecycles within ServiceNow, coordinating seamlessly with cross-functional technical groups.
- Collaborated with platform engineering teams to fine-tune detection rules, reducing false-positive alerts and enhancing
- detection accuracy.
- Executed prompt incident response actions using EDR platforms (CrowdStrike, SentinelOne, Microsoft Defender XDR),
- including endpoint isolation, malicious process termination, and live terminal forensic collection.
- Wrote and refined Kusto Query Language (KQL) hunting queries within Microsoft Sentinel to surface anomalous activity
- and accelerate alert investigation.
- Leveraged User and Entity Behavior Analytics (UEBA) in Microsoft Sentinel to flag anomalous identity activity,
- correlating findings with Microsoft Entra ID and Defender for Identity signals.
- Configured Sentinel Automation Rules and Logic Apps playbooks to streamline routine alert triage and reduce manual
- incident-handling time.
- Monitored the operational availability, health checks, and flawless log ingestion across distributed security devices and
- architectures.
- Conducted proactive threat hunting mapped against the MITRE ATT&CK framework, leveraging threat intelligence
- sources to pinpoint and prioritize emerging indicators of compromise (IOCs) for blocking.
- Documented comprehensive post-incident reviews detailing investigation findings, detailed timelines, and preventative
- remediation controls.
- Generated operational weekly and monthly security reports highlighting incident trends, response metrics, and firm
- cybersecurity posture.
- Assisted in third-party vendor cybersecurity posture assessment reviews to ensure strict organizational standard
- compliance.
- Engineered and tuned detection rules within Microsoft Sentinel and Palo Alto XSIAM to enhance detection accuracy and
- reduce false positives.
SOC Analyst
Nov 2023 — Jan 2026SISA Information Security Private Limited / India
- Conducted real-time monitoring and structural analysis of security events across network devices, Firewalls, IDS/IPS,
- Proxies, and Active Directory.
- Leveraged SIEM and Managed Extended Detection and Response (MXDR) tools for effective structural log aggregation,
- parsing, alert development and tuning, and correlation monitoring.
- Investigated, escalated, and delivered precise remediation recommendations throughout the entire containment,
- eradication, and recovery lifecycle.
- Analyzed low-fidelity alerts systematically to minimize queue metrics, and compiled daily firewall traffic patterns and
- operational reports.
- Managed tool log stoppage incidents, asset onboarding integrations, white-listing workflows, and routine health checks.
- Analyzed suspected phishing vectors using open-source intelligence (OSINT) tools and threat intelligence sources to
- block malicious payloads, identify IOCs, and prevent social engineering attempts.
- Provided technical mentorship and onboarding to junior SOC team members while maintaining absolute data privacy
- across security operations.
Cybersecurity Apprentice (SOC Operations)
Apr 2023 — Oct 2023SOCEXPERTS / India
- Participated in an intensive SOC apprenticeship program focused on hands-on threat monitoring, log analysis, and
- incident lifecycle management.
- Utilized Splunk for centralized log aggregation, data ingestion workflows, and engineering correlation alerts to track
- network behavior.
- Triaged simulated security alerts across endpoints and firewalls to map adversary techniques using the MITRE ATT&CK
- framework.
