Experience

  • Cyber Security Analyst at NexionPro Services
    Sep 2025 - Present · 11 mos

    As a Tier 2 SOC Analyst at NexionPro Services, I play a key role in strengthening the organisation’s security posture by leading in-depth investigations of complex security incidents and responding to advanced cyber threats. I analyse and triage escalated alerts, leveraging FortiEDR for detailed endpoint detection and response, and Splunk for comprehensive log correlation across enterprise environments including endpoints, servers, firewalls, and network infrastructure. I conduct root cause analysis, implement effective containment and remediation strategies, and continuously optimise SIEM detection rules to enhance threat visibility while reducing false positives. Additionally, I perform proactive threat hunting aligned with the MITRE ATT&CK framework to identify hidden risks before they impact business operations. Through detailed reporting, stakeholder communication, and close collaboration with cross-functional IT teams, I contribute to maintaining operational resilience, regulatory alignment, and a robust cyber defence framework.
