Introduction to HPE Aruba Networking’s authentication service on HPE Aruba Networking New Central

Central NAC

Company dynamics have changed in the past few years, welcoming an unprecedented volume of remote workers, as well as those working in hybrid environments. However, unreliable network access and new security concerns can disrupt business and cause help desk calls to soar.

Applying consistent security controls and ensuring users have seamless access to apps and data in the office, at home, and on the go is a critical mandate. HPE Aruba Networking Central simplifies this process for IT with Cloud Auth cloud-based Network Access Control (NAC), extending its ability to deliver a single point of visibility and control over all network infrastructure and related security services.

Featuring an easy-to-use interface and dashboard, HPE Aruba Networking Central makes it easy to onboard new clients, as well as to monitor and troubleshoot issues that prevent users from connecting to the network. End users are authenticated and provided authorizations for appropriate network access through fine-grained policies as configured by the administrator in HPE Aruba Networking Central.

With privacy concerns rising, HPE Aruba Networking Central leverages 802.1X for onboarding corporate devices and MAC-based authentications for non-802.1X devices. These authentication methods coupled with AI-based Client Insights captures and profiles all devices on the network for enhanced visibility and security.

Cloud identity

Cloud Auth on HPE Aruba Networking Central enables end users to connect to wired and wireless networks securely and automatically. The cloud-native security service integrates with a company’s existing cloud identity store such as Google Workspace or Azure Active Directory to authenticate the user’s information and assign them the right level of network access.

Automated security at scale from Edge to Cloud

Cloud Auth is an integral part of HPE Aruba Networking Central NetConductor, which streamlines the adoption of identity-based access and simplifies IT operations by delivering advanced, cloud-native configuration, management, and security services, including intent-based policy automation and orchestration, and AI-based discovery and profiling of all connected clients
