Zero trust network access (ZTNA) services, also known as a software-defined perimeter (SDP), are a set of technologies built to provide fast, secure access to private applications without placing a user on the network.
ZTNA services create an identity – and context-based, logical-access boundary around an application or set of applications. The applications are hidden from discovery, and access is restricted via a trust broker to a set of named entities. The broker verifies the user identity, context and policy adherence of the specified participants before allowing brokering the connection. This removes the application assets from being visible to the Internet and significantly reduces the surface area for attack.
Read this white paper to learn why and how ZTNA benefits both the information security function and the wider business.
