Vivek Mahajan
Principal Security Consultant with 11+ years of offensive security experience across fintech, government, trading, healthcare, and SaaS. I build adversary-aligned strategies, execute red team operations, and translate critical risk into actionable, leadership-ready remediation.
About
I design and run high-fidelity attack simulations, cloud security assessments, and security architecture reviews. My focus is measurable risk reduction with clarity that empowers leadership and blue teams to act fast.
I specialize in uncovering systemic weaknesses across complex environments and translating them into precise, prioritized remediation. From financial systems to critical infrastructure, my work blends adversarial realism with pragmatic defense outcomes.
I invest in continuous learning through labs, certifications, and hands-on research to stay ahead of evolving attack paths and emerging platforms.
