Controlled and secured access to a network or device is of prime concern across service provider, enterprise, and commercial deployments. Identity networking solutions that provide mechanisms to control network access are of high interest to such customers.Cisco Secure Access Control Server (ACS) is an industry-leading access control server that provides a comprehensive identity-based networking solution to enterprise customers for network access (wired, wireless, remote access) and device administration. Cisco Secure ACS extends security to users, machines, and device administrators by providing authentication, authorization, and accounting (AAA) services through robust access policies. The policies that define AAA access are managed from a centralized, identity-based networking framework that gives enterprise networks greater flexibility, mobility, and security, resulting in user-productivity gains.The Cisco Secure ACS family of products introduces the Cisco Secure ACS Express 5.0 that is intended for commercial (fewer than 350 users), retail, and enterprise branch office deployments. The product offers a comprehensive yet simplified feature set, cutting edge user-friendly GUI, and an attractive price point that allows customers to deploy this product in situations where Cisco Secure ACS for Windows or Cisco Secure ACS Solution Engine may not be suitable.
