TACACS+ is an Authentication, Authorization, and Accounting (AAA) protocol originally developed for the U.S. Department of Defense for authentication to network devices such as routers, switches, and firewalls. Unlike RADIUS, it separates the Authentication and Authorization functionalities, which makes it more flexible for administrative access. The current version of the protocol standard was developed by Cisco Systems.

Why you need TACACS+

TACACS+ simplifies network administration and increases network security. It does this by centralizing management of users on your network and enabling you to set granular access policies by users and groups, command, location, time of day, subnet, or device type. The TACACS+ protocol also gives you a complete log of every user's login and what commands were used. TACACS+ is recommended for compliance with most network security standards for E-Commerce, Health Care, Finance, and Government networks.

Why you should choose TACACS.net

TACACS.net software will turn your Windows PC or Server into a fully functioning TACACS+ server that can be used to enable specified local or Active Directory users access to log into and manage network equipment securely with Single Sign-On (SSO). Centralizing your user authentication on your Domain Controller or PC improves network security, saves you money, and simplifies administration.
