Best Network Access Control Software

As BYOD policies and the number of mobile devices accessing networks continue to proliferate, the enterprise attack surface grows wider, bringing in new security risks and vulnerabilities. It is therefore critical to have tools that provide improved network visibility and access management to protect devices and indeed the entire network from threats.

To address these challenges, Network Access Control (NAC) solutions are the answer. NAC solutions support network visibility and access control through policy enforcement on devices and users of corporate networks. It aims to do exactly what the name implies—control access to a network with policies, including pre-admission endpoint security policy checks and post-admission controls over which users and devices can go on a network, and what they can do.

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

  8. OPSWAT MetaAccess NAC A device detection and security assessing tool that pre-checks devices so that they can connect to the network. Offered as a physical or virtual appliance.

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.

Our methodology for selecting a network access control system

Using this set of criteria, we looked for network access control software that will enforce your system security.

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.

Twingate Screenshot from Demo

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.


  • Easy Access for Users Via a Small App: VPN-style interface that most users can understand without training
  • AD-Style Setup that Avoids Complicated ACL Definitions: Assign applications to the app menu for each user
  • Micro-Segmentation to Protect Each Resource: Imposes access control for each resource
  • Single Sign-On Mechanism to Ease User Movements: Alleviate the inconvenience of repeated login requirements
  • Treats On-Premises and Cloud Applications Equally: Access goes through the Twingate server for all connections


  • Not Actually a Network Access Control Package: This is a VPN-style service for internet-based virtual networks

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.


Twingate is our top pick for a network access control software package because it takes you through the strategy of network access control and on to the concepts of Zero Trust Access (ZTA). With the Twingate service, you can choose to just control access to networks but the package is able to implement access controls at a more finite level. You can take access controls right down to individual applications. This is microsegmentation, which is considered to be the future of network access control.

OS: Linux, Docker, Helm, AWS, and Azure

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.


  • A Menu of Services: Enables the implementation of a wide range of policies
  • Automated Blocking of Rogue or Unsuitable Devices: Only authorized devices allowed
  • Management of Virtual Networks: Connects sites to site and remote workers into the office
  • Compliance Management: For NIST, HIPAA, CIS, and PCI DSS


  • Doesn’t Include a Full Access Rights Manager: Focus on endpoint posture management

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.

One of the main concerns with MetaAccess is the fact that updates/upgrades on the appliances can only be performed by the vendor. This can be a turn-off for organizations that want a bit more control when applying updates to a system.

Network Access Control Software FAQs

What does a network access control do?

Network access control checks on the security attributes of devices before allowing them to connect. This task has become a great deal more complicated thanks to BYOD and virtual networks. NAC is an important requirement in modern system management because it is the first line of defense for corporate applications and data.

What is a NAC solution?

Network Access Control (NAC) isn’t a user account management system; it deals with devices instead. The NAC approach is to ensure that a device has no security weaknesses before allowing it to connect to the network. The system works with a series of policies, which are lists of requirements for each type of device. New devices are scanned to enroll them, which makes connections faster. However, security checks still occur every time that the device wants to connect to the network.

Is firewall a network access control?

Both a firewall and network access control defend a network. However, a firewall is a network device that stands at the boundary, examines traffic as it enters the network, while NAC operates within a network. Network access control examines each device and assesses its security strength before allowing it to connect.
