Daniel Sheehan

Cybersecurity graduate and SOC Analyst with a BSc in Information Technology & Cybersecurity from Munster Technological University, graduated with Distinction. In my current role, I triage and investigate security alerts across SIEM, EDR, NDR and MDR platforms, using log analysis and query languages such as KQL to identify suspicious activity, assess impact and document clear customer-facing findings. I have a strong foundation in Windows, Linux, networking and cloud security concepts, with practical exposure to common attacker tactics, techniques and procedures through alert investigation and case analysis.

I am particularly interested in threat detection, risk hunting, automation and large-scale security data analysis, and I am looking to build on my SOC experience in a role with greater technical depth, responsibility and scope.
