Andrew Lemke

I've built cyber defense, detection, response, and resilience capabilities for global enterprises across IT, OT, IoT, cloud, identity, data, and endpoint environments. My work combines hands-on engineering with executive advisory, including four issued U.S. cybersecurity patents.

At Kyndryl, I designed converged security operations architecture for an industrial client, authored the company’s cyber resilience reference architecture, and led Sheltered Harbor architecture work for the U.S. banking sector. I closed and delivered more than $30M in security services and technology scope while leading global consulting teams.

During nearly two decades at IBM, I served as Cyber Resilience Leader and built Brighthouse Financial’s cybersecurity program from the ground up following its MetLife divestiture. I also led IBM’s first adaptive security for hybrid cloud engagement, integrating 17 security services and technologies into one defense architecture.

I’ve led security engineering, compliance, and platform programs with multi-million-dollar budgets, including a compliance platform used by 90,000 IBM users. I bring deep experience translating HIPAA, FDA, SOX, PCI DSS, GDPR, and resilience requirements into engineered controls, measurable outcomes, and executive-level risk reporting.
