About Mark Lewel Suan

Cybersecurity professional with over five years of experience across SOC operations, network engineering, incident response, and military signal and cyber operations. I hold a TS/SCI clearance and currently work as a Senior Cybersecurity Analyst at ReliaQuest while serving as a Cyberspace Defense Warrant Officer in the U.S. Army National Guard. My technical foundation spans threat detection and analysis, detection engineering, vulnerability management, and cloud security across platforms including Splunk, Microsoft Sentinel, Cortex XSIAM, CrowdStrike, and Microsoft Defender. I write detection logic in KQL, XQL, and SPL, and approach every investigation with a bias toward thoroughness over speed. I hold a Master of Science in Cybersecurity and Information Assurance from Western Governors University, alongside certifications including CompTIA SecurityX, GIAC GCIH, CySA+, PenTest+, and AWS Solutions Architect Associate, among others. What drives me is the intersection of technical depth and real-world impact. Whether I am working a live incident, engineering a detection, or advising on architecture, I bring the same mindset: understand the threat, close the gap, and leave things better than I found them.
