Elena Kvochko is CIO of the Barclays Group Security Function. She is working to develop and establish holistic security which is based on adequate cyber hygiene, physical and cyber security controls, and common datasets. Ensuring a holistic approach in security has increased organisational efficiency and enhanced resilience. Barclays became the first global financial institution to focus on Holistic Security which redefines conventional approaches to cybersecurity and comprises cyber and physical security, as well as intelligence, investigations, and resilience. Barclays pioneered a new business model of holistic security, which can benefit other organizations that are reconsidering legacy technology and security models. An integrated security function covers the business environment and allows more visibility into normal and abnormal activities. It adapts security strategy to the current digital environment in order to bring innovation to the next level in the safest way possible and promote the benefits of secure business to all our clients, employees, and stakeholders. "Security by design" has become a core part of the processes.
