About Me

Cyrus Mehra

I am a Senior Cybersecurity Professional with a proven track record in Incident Response, Threat Management, Governance, Compliance, and Risk Mitigation. Over the course of my career, I have led and contributed to a wide range of security operations and strategic initiatives, helping organisations anticipate, withstand, and recover from complex and evolving cyber threats. My experience spans security operations, digital forensics, incident handling, risk assessments, and enterprise security frameworks, where I bring a balance of technical depth and strategic oversight. I ensure that cybersecurity practices are not only effective in addressing immediate risks but also aligned with global standards such as ISO 27001, CIS Benchmarks, and the Essential Eight to build long-term resilience and regulatory assurance.

In addition, I actively contribute to the academic and research community through peer-reviewed publications in internationally recognised venues, including IEEE, Elsevier, and Scopus-indexed journals and conferences. My research is centred on developing lightweight cryptographic techniques and practical security strategies that address the challenges of securing resource-constrained and rapidly evolving digital environments. By focusing on solving real-world cybersecurity problems, I aim to create approaches that are not only theoretically robust but also applicable in practice, enabling stronger resilience, compliance, and long-term protection for organisations and society at large.
