Why do you need network security access control for your company?

Network access control keeps unauthorized users and devices off a private network. Organizations that grant occasional network access to specific devices or users outside the organization can use network access control to ensure that those devices meet corporate security standards.

Importance of access control for network security

Access control is important to authorize who can gain access to the resources of a company. In an IT security setting, this can mean who can access and edit a specific file, what type of equipment can be used, or who can access specific devices, programs, and software.

The ultimate goal of access control is to provide a level of security that minimizes risk to a business or organization by helping to protect buildings, data, and people. For this reason, access control goes hand in hand with IT security. Without network security and access control, your employees and business can be vulnerable to issues such as data loss, theft, or violations of privacy laws.

What Are the Benefits of Network Access Control?

One benefit of network access control is that users can be required to authenticate themselves using multi-factor authentication, as it is more secure than using an IP address or username/password combinations to identify users.

Secure network access control also provides additional layers of protection for individual parts of the network after a user has gained access, thereby ensuring application security. Some network access control solutions may include supported security controls such as encryption and increased network transparency.

When should network security access control be used?

NAC for vendors or partners

Companies are required to work with their external partners and suppliers. The tricky part of network access control is granting network access to your providers and partners without exposing yourself to new attack vectors. A NAC solution typically includes a VPN (Virtual Private Network) client to allow external users to access internal resources over a secure channel.


The vast majority of companies today are enacting a BYOD policy, allowing employees to use their own personal devices at work rather than wasting money buying each person their own dedicated hardware. However, this greatly complicates the task of IT security as you do not have full control over how the devices on your network work.

An NAC solution blocks any new device from accessing the network until it fulfills the criteria of security policy. As an employee, this means you must install the NAC-approved client or app on your device to gain full access to the inside information.

Use of IoT devices

The Internet of Things has led to the proliferation of devices that can bypass traditional security controls, often located outside of the physical enterprise building but still connected to the corporate network. Cybercriminals can easily exploit these ignored devices to penetrate a network without access controls.Learn more at tools4ever.com

NAC for non-employees

Sometimes companies are required to offer access to persons or devices outside of their organization. Visitors, contractors, and suppliers may need access to an organization’s network, but not to all parts of the network and not every day. In this situation, network security access control offers controlled access and keeps it secure while they access the network.

Summing Up

Network security access control is important for every organization and government to make their networks secure and ensure the levels of access to their resources for visitors, vendors, and employees. Deploying a robust Network security access control solution enables organizations to keep their data, network, and resources secure.
