Access Control
Access control is a fundamental component of data security that dictates who’s allowed to access and use company information and resources.

Access Control Management
In computing, access control management refers to the management of access to systems, resources or other information for a user or user group. This often includes authentication to prove the identity of the user or group requesting access.

API Gateway
API gateway enforces security measures on API calls like IP whitelisting/blacklisting, authentication, content routing, rate limiting, and more to secure and manage your traffic in a single pass for better performance, lower complexity, and lower TCO.

API Security
With API Security, you get comprehensive protection for your APIs so that you can protect your valuable application and data assets, provide insight into the performance and use of your APIs, and help you make more informed decisions.

This enables the server hardware to be leveraged as a single pool of capacity such that any instance of a server operating system running as a virtual machine can be hosted anywhere in the pool.

Session Virtualization
Session virtualization uses application streaming to deliver applications to hosting servers in the datacenter. The user connects to the server to which the application has been delivered and the application then executes entirely on the server. The user interacts with the application remotely by sending mouse-clicks and keystrokes to the server, which responds by sending screen updates back to the user’s device.
