As now everything is moving to cloud, all the applications are accessible from anywhere and everywhere. However, No one wants their private information to be compromised and openly available for the world. We have been taking so many precautions, however breaches continue to happen. How should we fix this?

Organisations have been talking about Zero Trust lately and this has become a buzzword. The talk will explore Zero Trust beyond the buzzword and describe what exactly is Zero Trust and why it is so important to keep organisations safe. How can we implement or deploy Zero Trust in an organisation while keeping the current and future state of an organization in mind. What should be the business model to move any organisation towards Zero Trust Architecture and what all policies need to be implemented to achieve the same.

In the end, certain recommendations will be shared with the participants as a takeaway from my own experiences while working towards implementing the Zero Trust.
