The Best Network Access Control Software

Network Access Control (NAC) software plays a critical role in securing modern network infrastructures. It provides a centralized method of managing access to resources, ensuring that only authorized users, devices, and applications are granted access to the network. NAC software works by enforcing security policies that govern who can connect to the network, how they can connect, and under what conditions.

Here is our list of the best network access control software:

As organizations embrace hybrid environments, mobile workforces, and the Internet of Things (IoT), the need for strong NAC solutions has never been greater. With the growing number of cyber threats, managing network access has become a fundamental aspect of network security. NAC software helps mitigate risks associated with unauthorized access, such as data breaches, malware infections, and other security vulnerabilities.

By continuously monitoring and controlling access, NAC ensures that only compliant and trusted devices are allowed to join the network. It can authenticate users and devices based on various factors, including credentials, device health, location, and even behavioral attributes. This level of granular control helps organizations prevent unauthorized access and secure sensitive information.

Furthermore, NAC solutions are key in achieving compliance with regulatory standards such as HIPAA, PCI-DSS, and GDPR, which require organizations to implement specific security measures to protect data. A well-deployed NAC solution can automatically enforce these requirements, reducing the risk of non-compliance.

In this guide, we will explore the features, benefits, and top options available for network access control software, helping you find the right solution to secure your network and improve your organization’s overall security posture.

A NAC application can be set up to assess the security posture of devices attempting to connect to your network to determine if they meet predefined standards such as device type, OS version, update, and antivirus status, among others. If it doesn’t, the user is either denied access or placed onto a quarantined network segment until problems are rectified.

When evaluating NAC software or appliances, you need to ensure that it has the right features and capabilities that address your security risks and policy requirements. Some of the key questions to consider include: What do you need a NAC solution for; to manage guests, BYOD, IoT devices, or a combination of those? Is the NAC software able to integrate with existing software and network infrastructure? Does it support all kinds of endpoint devices—PC, Mac, Linux, Android, etc? Does it contribute to achieving compliance requirements? Is vendor support available in your region, and to what extent? Other factors to consider include features, agent or agentless implementation, and of course total cost of ownership.

The best network access control software

With such a huge range of NAC applications out there, choosing the right one for your business and budget can be challenging. In this article, we’re going to review the six best NAC applications in the market. Hopefully, this will guide you as you decide on the right NAC solution for your business.

1. Twingate (FREE TRIAL)

Twingate is a software solution for network access controls – you won’t get an appliance with this package. The Twingate solution controls access to applications and resources rather than implementing specific network access controls. This is because Twingate addresses the current dilemma that network manager face, which is that the office network no longer holds all of the resources that users need.

Key Features:

• Zero Trust Access: Application fencing
• Network Policy Enforcement: Scans devices for security weaknesses
• User Access Apps: Combines internet security with access authentication
• Single Sign-On: The app login gets rippled through to application access
• Hybrid System: Protects on-premises and cloud resources

Why do we recommend it?

Twingate is a VPN-based solution. The VPN client that goes on each user’s desktop requires a login and it enables credentials to flow through to access controls for network resources, applications, and SaaS accounts. This is a very easy system for any system administrator to set up and manage.

Access Control Lists can implement specific controls for different resources deep within a network while being run at the edge of the network. Using these techniques allows the segmentation of the network into security zones. Taking this segmentation down to its ultimate level, access control narrows down to protecting specific devices and then each application on each device.

Taking network segmentation down to its smallest unit is called micro-segmentation and it is the basis of Zero Trust Access (ZTA). this is where Twingate operates. Administrators don’t have to deal with Access Control Lists (ACLs) when using Twingate. This system operates in a similar format to Active Directory. Administrators create user accounts and a resource list. The resources are usually applications – particularly cloud-based SaaS systems – rather than infrastructure elements, such as a network or a server.

Who is it recommended for?

Twingate is a suitable network access control solution for any type or size of business. Small businesses can access the free Starter plan, which accommodates five users and covers network access control. The two paid plans are sized for mid-sized businesses and large enterprises.

Twingate is a software package that you have to host yourself. It will run on Linux but if you want to run your business on the cloud, you can run Twingate on AWS or Azure. You can also containerize Twingate with Helm or Docker. The Twingate system is offered on a 14-day free trial.

2. ThreatLocker Network Access Control (GET FREE DEMO)

ThreatLocker Network Access Control is part of a platform of system security tools that build a Zero Trust Access (ZTA) strategy. The NAC implements ZTA by forming part of the security policy enforcement. It is an endpoint posture management service that scans an endpoint before allowing it to connect to the network.

Key Features:

• Security Policies: Checks the security of an endpoint
• Blocks Rogue Devices: Controls are linked to a client app
• Dynamic ACLs: Interprets rules into access control entries
• Controls Access to Servers: Blocks unauthorized software

Why do we recommend it?

ThreatLocker Network Access Control is an interpreter for router access control lists (ACLs). It interprets your access policy into ACLs and inserts them into your routers. This eliminates the stress of trying to get all of your allow and deny lines in the right order – the tool has automated expertise built-in.

ThreatLocker is a cloud-based system, so it can take a God’s eye view of your network, even if the physical network has no clear boundary. This is a good solution for virtual networks. In fact, it is a key mechanism in the creation of a virtual network that can unify sites and include remote workers.

The NAC allows a device to connect to the corporate network or blocks it. The system can also impose controls on which endpoints can access which servers. One of the criteria that can be used when assessing an endpoint is its physical location. This is a great feature for businesses that need to comply with GDPR, which specifies that data can only be stored and processed within the EU.

Imagine a scenario of a business that holds user accounts in France and allows its invoicing clerks to work from home. One clerk decides to become a digital nomad, moving to Morrocco and still logging into the business to carry on with the same job from that laptop that used to be at home in Paris. Suddenly, that endpoint that was approved for access become unsuitable. The business manager doesn’t need to be notified about the move and the network manager doesn’t need to manually block that user’s account because the security policies and the NAC in ThreatLocker take care of all of the work automatically.

Who is it recommended for?

The ThreatLocker package is a very easy system to implement and it provides more than network access control. It will also block all malware and provide access controls for applications. This system compensates for any skills shortfall in your network management team and removes human error.

As a cloud-based system, ThreatLocker allows you to construct a corporate network that includes different sites and cloud platforms. The main focus of this system is to concentrate access rights on applications rather than physical resources. You can assess this strategy by accessing a demo of the ThreatLocker system.

• Device profiling and endpoint posture service

There are four primary ISE licenses available to customers as shown in Figure 2.0. These licenses as well as technical support can be purchased directly from Cisco certified partners.

Cisco ISE is a great tool, but it is best suited for organizations that have invested in Cisco hardware. If your network infrastructure is made up of equipment from different vendors, you may want to consider a NAC solution that is more suitable for your environment.

Who is it recommended for?

The presentation of this system is very technical and you would have need to have taken a network security course just to understand the website. Fortunately, the administration console makes implementing the system a lot easier than it sounds. However, this is a solution that is best suited for large companies with complicated hybrid networks.

With Cisco Identity Services Engine, you can actually host it on your own network – these days NACs tend to be cloud services. This is an extensive service that examines both user accounts and devices with possible combinations of those two areas of security. The service is great for managing hybrid environments, being able to handle security policies for on-site and internet-based virtual networks as well as LANs and wireless systems. ISE is a great component for Zero Trust Access (ZTA) and is comprehensive, so it will be able to form part of the security strategy of any new network configuration that comes along. You can start by registering for a demo.
