RBI Category Definitions

The RBI specific web categories shown in the UI are explained in the table below.



Newly Registered Domain

All the newly registered domains are placed under this category.

Newly Observed Domain (NOD)

Domains observed as active in the last 30 days. These domains are potentially malicious as bad actors can use the domain for malicious activities such as malware hosting and phishing.

NOD has been added to the list of recommended categories in RBI Real-time protection policies, and it is now included by default in any RBI policy created leveraging the RBI policy creation wizard. You can edit existing RBI policies to add NOD to your isolation Real-time protection policies.

No Content

Sites that don't have any content on the entire site are categorized as No Content.

Parked Domains

Parked Domain is the registration of an Internet domain name without that domain being associated with any services, such as e-mail or a website. This may have been done to reserve the domain name for future development, and to protect against the possibility of cybersquatting. Examples are parked domains, for sale call domain owners, etc.


Domains that are yet to be categorized.

Web Proxies/Anonymizers

Web proxies and anonymizers are services that allow users to hide their identity, IP address and location when they browse the web. Unlike apps in other categories, which might have a justification for being used, proxies and anonymizers pose a security and legal risk to the organization and should be blocked. Netskope Cloud Confidence Index (CCI) does not apply to these apps.
