Network Access Control

What is the importance of network access control?

NAC is critical for modern businesses because it allows organizations to monitor the devices and users — authorized and unauthorized — trying to access the network.

Unauthorized users include cybercriminals, hackers and data thieves, and other bad actors that an organization must keep out. But businesses must also be gatekeepers for authorized users. This particularly applies to organizations that allow remote access to the enterprise network from non-corporate devices like mobile phones, laptops and tablets, or companies that allow employees working in the office to use personal devices. Both scenarios create security risks demanding organizations to address network security.

NAC is one aspect of network security. It provides visibility into the devices and users trying to access the enterprise network. And it controls who can access the network, including denying access to those users and devices that don’t comply with security policies. NAC solutions and tools help companies control network access, ensure compliance and strengthen their IT infrastructure.
