Best Zero Trust Networking Software

One of the main weaknesses of the traditional approach to security is that it assumes that everything inside an organization’s network can be trusted. One implication of this assumption is that it keeps us blind to threats that get inside the network, which are then left to freely roam and attack the network wherever they choose.

To overcome this deficiency, organizations must adopt a new approach to protect the modern network infrastructure and fluid network perimeter that extends to the cloud, and the increasing number of mobile or dispersed users. This new approach is called zero trust security model or zero trust network access (ZTNA).

Here is our list of the best Zero Trust Networking Software:

What is Zero Trust Network Access (ZTNA)?

Zero Trust Network Access (ZTNA) is a shift in approach to security whereby access is denied unless it is explicitly granted and the right to have access is continuously verified.

The idea behind zero trusts is that the network devices should not be trusted by default, even if they are connected to a corporate network or have been previously verified.

The zero trust approach advocates checking the identity and integrity of devices irrespective of location and providing access to applications and services based on the confidence of device identity and device health in combination with user authentication. ZTNA reduces insider threat risks by always verifying users and validating devices before granting access to sensitive resources. For outside users, services are hidden on the public internet, protecting them from attackers, and access will be provided only after approval from their trust broker. According to Gartner, by 2022 80% of new digital business applications will be accessed via ZTNA.

Most ZTNA solutions are implemented as a Software-Defined Parameter (SDP). Zero trust networks enabled as SDPs are in a better position to manage cyber-attacks across networks. The zero trust network framework comprises the following key components:

  • Visibility: This helps security teams gain deeper network visibility, and track the flow of data and device as it moves through its lifecycle.
  • Micro-segmentation: With micro-segmentation, organizations can limit internal access to networks and assets to only those that need to reach those assets. This helps to reduce the total attack surface of the network. and it entails moving the perimeter to workloads.
  • Least privileged access: ‘Least privilege’ principle allows users to access only the resources and applications they need to effectively do their job.
  • Monitoring: AI technology can be used to continuously monitor risk and trust to ensure the right security posture is maintained.

The best Zero Trust Networking Software

With the right ZTNA solution, organizations can ensure proper user context through authentication and attribute verification before allowing access to network resources at a fraction of the cost, complexity, and security risk of the traditional approach. In this article, we’re going to review the seven best ZTNA solutions in the market. Hopefully, this will guide you in the process of choosing the right solution for your business.

7. NetMotion ZTNA

The NetMotion zero trust solution combines ZTNA, SDP, and enterprise VPN solutions to provide organizations secure access to their digital assets and resources. It can be deployed on-premises, or in the cloud (public, private, and hybrid). The easiest way to take advantage of the NetMotion platform is to implement it as a service.

The NetMotion client installed on user devices acts as the controller, gathering real-time data about the host device, applications, network connections, and analyzing the context of every user request for resources. The data gathered is then used to build a risk profile of each request to determine whether the user can access the resource based on the immediate context. The NetMotion gateway which can be installed on-premises or in the cloud ensures that all company resources are protected. If the controller approves users’ access to a resource, traffic is routed to this gateway and directly to the destination requested. Some of the key features and capabilities of the NetMotion zero trust platform include:

  • Combines ZTNA, SDP, and enterprise VPN in a single platform
  • A single agent and console to manage remote devices, analyze data, and apply policy
  • Dynamic web filtering and enforcement of access policies on a contextual basis
  • Flexible deployment options, including cloud, hosted or on-premises
  • Security reputation information on websites and applications.
  • Real-time risk assessments of every access request

NetMotion licenses are available in two subscription options:

  1. The Complete subscription This option grants customers access to the entire range of functionality – ZTNA, SDP, VPN,  experience monitoring, and others.
  2. The Core subscription: This option grants customers access to a limited range of functionality.

A 30-day free trial is available on request.

Choosing the right ZTNA solution for your business

While ZTNA has many use cases, most organizations choose to use it as a means of access to hybrid and multi-cloud services, an alternative to VPN, and a means to eliminate over-privileged access to resources, among others.

Like most network security solutions, not all zero trust solutions are created equal. What fits perfectly from a price, feature, and functionality standpoint for one organization may not fit for another. You need to consider a variety of factors, some of which include: What deployment model best suits your environment—cloud or on-premises? Does the deployment model meet your organization’s security and residency requirements? Does the  ZTNA solution require an endpoint agent to be installed? Does the trust broker integrate with your existing identity provider? Is vendor support available in your region, and to what extent? How geographically diverse are the vendor’s edge locations worldwide? What is the total cost of ownership?

These solutions can be deployed as on-premises or standalone service, cloud service, or as a hybrid service, combining cloud and stand-alone offerings. If you find any of these solutions useful, or indeed other solutions, let us know in the comments.
