Hi, I'm Dhanika.

Cybersecurity×Governance, Risk & Compliance

I'm an ISO 27001 Certified Lead Auditor with 3+ years in IT, now focused on cybersecurity and GRC — governance, risk assessment, security controls, and audit-ready compliance. I pair an operations mindset with hands-on blue-team practice through home labs (Wazuh, Sentinel, Sysmon, MITRE ATT&CK).

Governance, risk & a security mindset.

Who I am and what I bring to a team.

My focus is cybersecurity and GRC — governance, risk assessment and management, security controls, and compliance processes — backed by practical blue-team work with Wazuh, Microsoft Sentinel, Sysmon, and MITRE ATT&CK, documented on my blog.
