ABOUT THAHDHEEL THAHIR
Most compliance programmes don\'t fail because of bad people — they fail because no one owns the problem end to end. That\'s the gap I close.I\'m a Cybersecurity GRC and Compliance Manager with 7+ years of experience helping large enterprises — including Vodafone and Virgin Media O2 — build compliance programmes that actually hold up under audit pressure. I\'ve led ISO 27001 and NIST-aligned control frameworks, run enterprise-wide gap analyses, and delivered exec-level risk reporting that gives leadership real visibility, not just green dashboards.What I do in practice: I take sprawling, fragmented compliance environments and bring structure to them — clear control ownership, evidence pipelines that work, and remediation that sticks. At Vodafone, I redesigned the governance model across multiple business units, closing systemic gaps and materially improving audit readiness. At VMO2, I led a full service transition in two weeks with zero operational disruption, while simultaneously cutting manual effort by 90% through workflow automation.I work well at the intersection of technical teams and senior leadership — translating complex risk into language that drives decisions, not just discussions.What I bring to a Compliance Manager role: → ISO 27001 & NIST control assurance, end to end→ Audit readiness and regulatory alignment at scale → Executive reporting and governance committee engagement → Cross-functional delivery across IT, Risk, Legal, and Cyber teamsI\'m currently exploring my next senior compliance opportunity — ideally in a complex, regulated environment where there\'s real work to be done, not just boxes to tick.If want to have a conversation, reach me at t••••••••@gmail.com or connect directly here on LinkedIn.
