NTT DATA making Zero Trust Real

Hiroshi Honjo- Head of Cybersecurity and Governance at NTT DATA’s Technology and Innovation General Headquarters in Tokyo, Steve Williams- Enterprise CISO at NTT DATA and Markus Kunzler- EMEA CISO at NTT DATA EMEA Ltd. share their learnings from NTT DATA’s implementation of Zero Trust and why CISOs must look to Zero Trust as the means to not only secure their business but also to continue earning the trust of their clients/customers.
The Zero Trust Model has been widely accepted by the global security community as the best method to secure our constantly evolving and interconnected global ecosystem. In a journey towards zero trust, you must decide what approach you are going to take. NTT DATA started out with Identity which is at the heart of a secure, adaptable, and decentralized workforce. Implementing Zero Trust required a cultural change but brought with it many benefits including

  • Optimized vendor relationships and reduced training and license costs by leveraging a common set of technology
  • Decreased security vulnerabilities by leveraging a common global security framework
  • Cost reduction and optimization through standardization
  • Cost and risk reduction through automation
  • Decreased support costs and helpdesk tickets

Watch the video to learn how your organization can gain these benefits through implementing a Zero Trust framework
