Information Security Analyst | Incident Response | Identity & Privileged Access | Security Automation

Information Security Analyst at The Timken Company, where I lead endpoint incident response and remediation for the North American region. My work spans detection and response, identity and privileged access management, data loss prevention, and security support for M&A integrations.

Recent work includes a privileged access review that substantially reduced standing administrative access across the environment, and authoring a security automation development standard governing input validation, scope control, credential handling, and change control for administrative tooling.

Outside of work, I continue building practical security tools, including The EntropyX Platform, my enterprise compression suite, identity governance platform and home network security application.

About Me

Information Security Analyst with 4+ years of experience across incident response, vulnerability management, and enterprise security operations in global environments. At The Timken Company I lead endpoint incident response and remediation for North America, serve as primary analyst for enterprise data security monitoring, and support InfoSec workstreams for mergers and acquisitions. Earlier, at Apple Growth Partners, I served as cybersecurity administrator for a firm with no dedicated security team and raised firm-wide security compliance from 50% to 85%.

My focus is increasingly on the governance side of security operations: reducing standing privileged access, and making the automation that administers identity safe to run. I recently led a privileged access review that substantially reduced the administrative account population, and authored a security automation development standard covering input validation, mandatory preview on destructive operations, scope control, credential handling, and change control.

My background spans endpoint detection and response, data security and DLP, SIEM operations, endpoint management, Active Directory and Entra ID, managed file transfer, and PowerShell automation. Certified in ISC2 SSCP, CompTIA SecurityX (CASP+), CySA+, Security+, and PenTest+.
