Helios Features

Helios provides:

Multi-cluster management: Actively manage all your clusters, including multi-cluster monitoring, reporting and orchestrated upgrades, from a single dashboard.

Managing self-managed clusters through Helios does not require an additional license.
Multi-service management: Actively manage all your Cohesity Cloud Services such as Security Center, SmartFiles, and Platform Insights through Helios
Global actionable search: Search across clusters and take action right from the search results page. For example, search for all unprotected VMs and create jobs to protect them.
Security tools: Detect threats and other anomalies across clusters with the unified Alerts page.

Changes that you make to the cluster while using Helios might not appear in the regular Cohesity Dashboard for fifteen minutes.

For cluster-specific documentation, see Cohesity Documentation Home page.

In Helios, the data and metadata are secured by different services based on the use case. For more information, see Secure Data Management in Cohesity Data Cloud (SaaS) and Cloud Services Security Brief.
