Additionally, ClearPass offers a number of other features such as the ability to monitor and report on network activity, the ability to enforce security policies, and the ability to integrate with other security solutions.

3. How does ClearPass differ from other NAC solutions?

ClearPass is a next generation NAC solution that offers a number of advantages over traditional NAC solutions.

This allows for a more granular level of control and policy enforcement. ClearPass also offers a number of built-in security features, such as the ability to detect and block malicious devices, that other NAC solutions do not.

4. Why should we use ClearPass over other vendor solutions like Cisco ISE?

ClearPass has a few key advantages over Cisco ISE. First, it offers a much higher degree of flexibility in terms of policy creation and enforcement. This allows you to more easily create custom policies that fit your specific needs. Second, ClearPass also offers a much richer set of features and functionality, including the ability to integrate with a wide variety of third-party devices and systems. This makes it a much more comprehensive solution for network access control.

5. When would you recommend that a client uses ClearPass instead of a Microsoft solution for network security?

ClearPass is a great solution for network security, especially in cases where the network is complex or there are a lot of devices that need to be managed. It can also be a good choice if the client is looking for more granular control over security policies.

6. What is the difference between ClearPass Guest, Onboard, and Enforcement?

ClearPass Guest is used to provide guest access to a network, Onboard is used to automate the provisioning of devices onto the network, and Enforcement is used to enforce network access policies.

7. In which cases would you not recommend using ClearPass?

There are a few reasons why you might not want to use ClearPass. First, if you have a very small network with only a few devices, then ClearPass may be overkill. Second, if you are not concerned about security and just want a simple way to manage your network, then ClearPass may not be the right solution for you. Finally, if you are already using a different network management solution that you are happy with, then there is no need to switch to ClearPass.
