What is the purpose of ringfencing in application segmentation?

The purpose of ringfencing in application segmentation is to allow communication within an application while effectively controlling and limiting necessary traffic. This approach offers a flexible security measure that ensures internal components of an application can function correctly without being hindered by overly restrictive traffic policies. Ringfencing accomplishes this by creating a protective boundary that enables authorized interactions between workloads within the application while still restraining or monitoring external communications and interactions with other applications.

This method is particularly useful in maintaining application performance and functionality while enhancing security, as it carefully curates what traffic is deemed necessary and permissible within the application's ecosystem. By protecting the critical interactions internal to the application, organizations can reduce their risk exposure while still promoting seamless operational continuity.
