Briefly take us through your professional experience highlighting the crucial junctures that influenced your path to becoming a CISO?
Subsequently, I was responsible for enterprise security strategies, advising executives and integrating security into 4G/5G, cloud, and customer platforms for secure growth. Currently, I believe that a CISO is a strategic role that must balance security and business growth in trusted and resilient environments, and lead teams that perform at their best.
With over 25 years of experience in network, security, and cloud technologies, I take pride in having built my career from scratch. This experience has helped me develop my own insights into threat landscapes and the practical challenges of securing large-scale enterprise and telecom environments. I transitioned into risk and governance to better align security with business strategy, translating technical risks into clear actionable business guidance and supporting regulatory engagements.
In recent years, how has the role of the CISO transformed, particularly within a rapidly expanding, technology-focused setting?
The contemporary CISO has evolved from the conventional reactive security operations to play a central strategic role with a forward-looking focus. Contemporary CISOs serve as risk executives, managing security risk in relation to
business goals to facilitate speed and innovation. CISOs manage governance, regulatory and ecosystem risks, communicating cyber threats in terms of resilience and enterprise value based on the organization's scale.
To what extent do technologies such as AI, automation, and zero-trust architectures contribute to the development of contemporary cybersecurity methodologies?
From a strategy point of view, AI, automation, and zero-trust models are excellent cyber security enablers, but their effectiveness in reality is what matters. AI increases the speed, scale and accuracy of threat detection, making it a game-changer in the field of cybersecurity, but its success largely depends on effectively integrating cutting-edge technology with strong governance and human insight.
As automation increases efficiency and accuracy, it makes it easier to automate repetitive tasks so that teams can scale and make risk-based decisions. The current hybrid and partner-based environment is made secure by zero trust models.
How do you approach leadership, particularly when handling critical security incidents?
My leadership approach is best exemplified in addressing critical security incidents, where I lead the front with calmness and account ability, setting clear direction, ensuring accurate and timely communication, and driving swift, risk-informed decision-making. Incident response requires separating facts from assumptions, maintain transparency with management, and promoting a safe, decisive team culture.
Security teams perform to their full capacity when empowered with accountability, guided by business priorities, and are trained for continuous adaptation. Ultimately, my focus is on creating teams that provide trusted guidance and respond decisively in critical moments.
How do you anticipate cybersecurity evolving in India? What specific risks or patterns should businesses pay close attention to in the future?
As cybersecurity becomes central to enterprise trust, India is experiencing accelerated growth. Security innovation is now being largely driven by strengthened regulations, widespread digital transformation and increased collaboration with agencies like CERT-In. Globally, organisations are moving from prevention to intelligence-led approaches, prioritizing breach readiness and swift response.
As preventive control, boards must monitor AI-powered threats, supplychain vulner abilities, cloud and identity risks, regulatory complexity, and geopolitical tensions. Rather than perfecting the outcome, focus
