Zero Trust is the future of cybersecurity, ensuring continuous verification, adaptive security, and resilience against evolving cyber threats in a borderless digital world
As cyber threats continue to evolve in complexity, traditional security models are proving inadequate in safeguarding organisations from potential breaches. In this context, Zero Trust Architecture (ZTA) has emerged as a crucial cybersecurity strategy, ensuring that no entity is automatically trusted, whether inside or outside the network. Experts across the cybersecurity industry stress that organisations must adopt Zero Trust to secure digital assets, comply with stringent regulations, and maintain operational resilience.
Zero Trust: Shift From Perimeter-Based Security
Unlike traditional models that assume trust within a corporate perimeter, Zero Trust operates on the principle of “never trust, always verify.” It requires continuous authentication, strict access controls, and real-time monitoring to minimise security risks. Madhusudan Krishnapuram, VP – Product & Engineering & MD, GoTo India, explains why this model is crucial in today’s digital workspace:
“Zero Trust is the security standard for a world where work happens anywhere. In a traditional office, security was like a keycard—once inside the building, you could move freely. But in today’s distributed work environment, that model falls apart. Zero Trust flips the script: it is not just about keeping bad actors out. Instead of assuming trust based on location, it continuously verifies every user and device, no matter where they are.”
With organisations operating in hybrid environments, cybercriminals have begun targeting remote access and IT automation systems, which hold deep access to company endpoints. Krishnapuram adds that Zero Trust Network Architecture (ZTNA) creates encrypted tunnels between users and network resources, ensuring that sensitive data remains secure, even on public networks.
Addressing Regulatory & Compliance Challenges
Governments worldwide are tightening data privacy regulations, making Zero Trust not just a security measure but also a compliance necessity. Rishi Agrawal, CEO and Co-Founder of Teamlease Regtech, highlights how India’s Digital Personal Data Protection Act (DPDPA) is shaping security frameworks:
“India is setting new benchmarks for data protection while cultivating trust among businesses and individuals. The Digital Personal Data Protection Rules are on the verge of being notified, marking a significant shift in how businesses handle both personal data and data in general. The DPDPA mandates explicit consent, purpose limitation, and robust data protection practices. As cyber threats grow in complexity, organisations must adopt a more dynamic and proactive security model—one that Zero Trust security, powered by adaptive policies, is uniquely positioned to provide.”
Role Of Dynamic Policies In Zero Trust
Static security controls are no longer effective against modern cyber threats. Hashyadeep Dave, CEO, 3CIT Solutions & Telecom (India) Limited, underscores the importance of adaptive, real-time security enforcement:
“Zero Trust operates on the principle that no entity inside or outside the network is automatically trusted. It enforces continuous verification, strict access controls, and real-time monitoring. Core principles include verifying every user and device before granting access, enforcing least privilege access, segmenting networks to limit lateral movement, logging all activity for anomaly detection, and encrypting data in transit and at rest. The benefits are substantial—reduced risk of insider threats, stronger regulatory compliance, and enhanced resilience against modern cyber risks.”
Similarly, Major Vineet, Founder and Global President of CyberPeace Foundation, highlights the risks of blind trust in legacy security systems:
“Cyber adversaries exploit neglected vulnerabilities, credentials, and lateral movement within networks. Zero Trust counters this by imposing real-time risk assessment through AI analytics, Secure Access Service Edge (SASE), endpoint protection, and identity authentication. Security today is not about building taller walls but eliminating blind trust. In a Zero Trust model, every device, user, and application is continuously validated, ensuring robust protection against an ever-evolving threat landscape.”
Zero Trust In Large-Scale Enterprises
For large enterprises, implementing Zero Trust is crucial for long-term cyber resilience. Saket Verma, Cybersecurity Practice Leader at Kyndryl India, discusses why organisations need to rethink their security models:
“Kyndryl’s recent cybersecurity survey highlights that 54 per cent of large organisations faced IT or data disruptions due to cyberattacks in the past year, with India ranking among the top three most affected countries. Despite 94 per cent of organisations expressing confidence in their security posture, 71 per cent anticipate a disruptive cyber incident in the coming year that could impact financial performance. This gap between perceived readiness and actual resilience underscores the urgent need for organisations to rethink their security frameworks.”
Verma stresses that Zero Trust is not just a technology upgrade but a fundamental security transformation:
“Unlike traditional perimeter-based security, it relies on a proxy-based architecture that inspects all traffic, including encrypted data, in real time. At Kyndryl, Zero Trust is a fundamental pillar of our cyber resiliency strategy, helping organisations secure critical assets, align security initiatives with business objectives, and future-proof themselves against evolving threats.”
Future Of Zero Trust Security
Zero Trust is no longer an optional cybersecurity measure; it is a necessity in an era of rapid digital transformation. As cyber threats grow in complexity, organisations that fail to adopt Zero Trust risk falling behind in both security and compliance. Experts agree that continuous verification, adaptive security policies, and AI-powered risk assessments will define the future of cybersecurity.
As Major Vineet puts it:
“The future of cybersecurity is not about ‘trust but verify’—it is about ‘never trust, always verify’.”
