Cloud Requirements

For requirements specific to Tenable Security Center and Container Security, see the following topics:

Note: Tenable recommends using an empty Kubernetes cluster for Tenable Enclave Security deployments. These requirements assume that the Kubernetes cluster where you install Tenable Enclave Security has nothing else installed.

Tenable strongly recommends using high-performance disks when you deploy Tenable Enclave Security in a Kubernetes cluster. Tenable Enclave Security is a disk-intensive application and using disks with high read/write speeds (for example, SSDs or NVMe SSDs) results in the best performance. The requirements in the following tables are based on AWS M5 or better processor specifications. Using slower processors, like those found in AWS M5a instances, will impact performance for your Tenable Enclave Security deployment.
