I am a Security Analyst with 2+ years of experience at Accenture Solutions Private Limited, where I successfully managed end-to-end incident handling, achieving zero missed critical incidents during my tenure. My expertise in real-time alert triage and threat investigation using tools like Splunk, Microsoft Defender, and CrowdStrike has sharpened my analytical skills and deepened my understanding of cybersecurity challenges. I am now focused on expanding my career as a Cybersecurity Engineer, where I can leverage my hands-on experience to enhance security infrastructures and proactively address emerging threats.

Experience

Accenture Solutions Private Limited

Oct 2021 – Aug 2024

Monitored and triaged thousands of real-time security alerts across Splunk SIEM, performing end-to-end incident handling — alert validation, root cause analysis (RCA), containment, and SLA-compliant escalation to L2/L3 teams — resulting in zero missed critical incidents during tenure. Investigated diverse threat scenarios including phishing attacks, malware infections, brute-force attempts, account compromises, and data exfiltration indicators by analyzing logs from firewalls, EDR/XDR, email gateways, Windows Event Logs, DNS, VPN, proxy, and IDS/IPS systems; mapped findings to the MITRE ATT&CK framework for structured threat reporting. Led email security analysis workflows — including email header inspection, URL sandboxing, and malicious attachment investigation — and executed remediation actions (blocking IPs, domains, hashes, and senders at firewall and email gateway level), directly reducing phishing exposure for end users. Maintained accurate SOC documentation including incident records, investigation case notes, and daily/weekly/monthly reports; contributed to playbook development and post-incident recommendations that improved repeat-incident reduction and enhanced team-wide detection capabilities.
