Cisco Secure Access Control Server (ACS) Express is an entry-level RADIUS and TACACS+ authentication, authorization, and accounting (AAA) server for retail branch locations, enterprise branch offices, and small and medium-sized businesses (SMBs) that have fewer than 350 users and 50 devices.
Cisco Secure ACS Express provides a centralized identity networking solution that:
An easy to use GUI that also encompasses the intricacies of defining a highly evolved identity policy helps speed identity solution setup and deployment for small deployments.
Flexible Access Policies
A simplified yet comprehensive access policy allows for the definition of multiple profiles for network access, wireless access, remote access, and device administration while offering the flexibility to enable an identity deployment to support multiple access types from a single central identity server.
External Database Support
Support for Active Directory, Lightweight Directory Access Protocol (LDAP), and one-time password (OTP) servers allow deployments to integrate with their user repositories.
Native Access to Microsoft Active Directory
Smooth authentication against Active Directory eliminates the need to install or configure any agent on either the Cisco Secure ACS Express appliance or any other server to interact with Active Directory.
Support for a wide array of access protocols--such as RADIUS, Extensible Authentication Protocol (EAP), and TACACS--gives you the ability to control access to a variety of connection types into the network.
Support for high availability between a pair of Cisco Secure ACS Express servers enables redundancy if one server is unavailable from a network attached storage (NAS) device's point of view.
Remote upgrades and patches provide administrators with greater remote management options.
Secure administration using a Web GUI (HTTPS) or scriptable command-line interface (CLI) provide flexibility in remotely managing individual Cisco Secure ACS Express appliances directly or in bulk through the use of automated scripts.
