Security Center in Tenable Enclave Security System Requirements

Tenable Security Center in Kubernetes Requirements

Tenable strongly recommends using high-performance disks when you deploy Tenable Security Center in a Kubernetes cluster. Tenable Security Center 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 Security Center in Kubernetes deployment.
