What is Network Access Control?

You are currently viewing What is Network Access Control?

As cloud computing and digital storage become the norm, it’s critical that companies learn how to strengthen the security of their online data. And with new factors coming into play like Bring Your Own Device (BYOD) and remote work, network access control is no longer just a good idea, but a necessity. 

Network Access Control (NAC) prevents unauthorized users and devices from accessing a private network. 

But having an NAC solution isn’t only for keeping hackers at bay. 

NAC also dictates which information employees can access based on their positions within the company. This provides increased security for remote employees, employees who work from multiple devices, and guests who need access to the network.

The Importance of Having a Network Access Control Solution

Imagine you’re the CEO of a small business with 200 employees. You store most of your data digitally, and you keep all of your files in one central location to make them easier for your employees to access. 

Things are going well until one of your employees falls prey to a phishing scam. By clicking a malicious link, the employee has unknowingly given a hacker access to your network. 

And since all of your employees have access to the same data, now, so does the hacker. 


Setting up network access control might not seem like a necessary step, but it’s invaluable for your organization’s security. 

If everyone in your organization has access to all of the company’s data, then sensitive information is much more likely to fall into the wrong hands. 

Instead, by implementing an NAC solution, you ensure that employees can only access the information they need, keeping your sensitive data more protected.

How Network Access Control Works

So how does network access control work? 

To start, your NAC solution will create rules for your specific network. These rules dictate which users can enter the network, which devices they can log in from, and which information they can access. 

Network access control also streamlines your onboarding and offboarding process since you can quickly create access for new employees and revoke permissions for employees leaving the company. If an employee’s roles or responsibilities within the company change, their permissions within the network will also change.

Final Thoughts

With the digital world growing more complex, it’s essential that you have a policy in place to protect your data from unauthorized access. 

Network access control allows you to customize a solution for your company that will keep your data organized and prevent sensitive information from falling into the wrong hands.
