WORK HISTORY

ABOUT JACK LEIVESLEY

I focus on building pragmatic, measurable cyber capabilities that align technical controls with real business outcomes. My goal is to help organisations reduce risk in practical ways and clearly demonstrate the value of their security investments.At Core to Cloud, I support a range of security priorities, including enabling secure GenAI adoption so teams can unlock productivity safely, reducing ransomware dwell time and business impact, and designing end-to-end resilience programmes that embed readiness across organisations, teams, and individuals.My work spans strategic initiatives that resonate with executives, practical AI risk controls, ransomware containment and recovery playbooks, and optimising tools and processes so security teams can operate more effectively with limited resources.I bring together technical depth and business-focused thinking to deliver initiatives that are measurable, repeatable, and grounded in real risk reduction. I’m particularly focused on ensuring security efforts are understood, sustained, and aligned to what actually matters.Always open to conversations about security challenges, priorities, and how organisations can move forward with clarity and confidence.
