As sophisticated cyber threats are increasing, Karnataka Power Transmission Corporation Limited (KPTCL) has implemented a Zero Trust Security Framework, becoming one of the first State transmission utilities in the country to adopt the globally recognised cybersecurity architecture for safeguarding critical power infrastructure. The initiative aims to tackle and prevent sophisticated cyber threats while securing mission-critical operational, engineering, financial and administrative systems. A release stated that there are more than 3,000 users accessing critical applications from corporate offices, substations, operational centres, field locations and remote environments, hence, the KPTCL identified the need for a modern cybersecurity framework capable of protecting its rapidly expanding digital ecosystem.

Unlike conventional perimeter-based security models, the framework follows the principle of ‘Never Trust, Always Verify’. Every user, device and access request is continuously authenticated and validated based on identity, device health, user privileges and risk context before access to any application or resource is granted. The KPTCL release stated, “As part of the transformation, we have deployed Zscaler’s cloud-native Zero Trust Exchange platform for nearly 3,000 enterprise users. The platform enables secure, direct access to authorised applications without exposing users or critical systems to the public internet, eliminating the security vulnerabilities associated with traditional VPN-based access.” The new security architecture substantially reduces the KPTCL’s cyber attack surface while providing stronger protection against phishing attacks, ransomware, malware, data breaches and more.

Continuous authentication, least-privilege access controls and intelligent security policies ensure that only verified users gain access to critical systems, while centralised monitoring enables faster threat detection and incident response. Appreciating the move, K.J. George, Minister for Energy and Tourism, said, “As Karnataka continues to modernise its power

infrastructure, strengthening cybersecurity has become as important as strengthening the physical grid itself. The implementation of the framework reflects our commitment to protecting critical public infrastructure through globally accepted cybersecurity standards. A secure digital ecosystem is essential for delivering reliable power to citizens, industries and public institutions.”
