The Best Zero Trust Security Vendors

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 the zero-trust security model or zero-trust network access (ZTNA).

Here is our list of the best Zero Trust Security Vendors:

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 trust 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 zero-trust network access (ZTNA).

1. Perimeter 81 (ACCESS FREE DEMO)

Dec 2024

Perimeter 81 is an Israeli cloud-based network security company that develops secure remote networks based on the zero-trust architecture. Perimeter 81 is on a mission to transform traditional network security technology with one unified Zero Trust Network as a Service (ZTNaS).

Key Features:

• Remote access
• Cloud application protection
• Integrated access rights management
• Cloud-based hub
• Connection protection

Why do we recommend it?

Perimeter 81 is easy to understand. Imagine a VPN service where the user selects a location and then connects. With this system, the user logs into the client application and after turning the connection on, is able to select from a menu of applications. The credentials used for app access are copied through for application access.

Perimeter 81’s zero trust solution is offered via the following platforms:

• Zero Trust Application Access Helps to ensure zero trust access to web applications and remote network access protocols such as SSH, RDP, VNC, or Telnet, through IPSec tunnels – without an agent.
• Zero Trust Network Access Helps to ensure zero trust access to on-premises and cloud resources with one unified cloud platform.
• Software-Defined Perimeter Helps organizations conceal internal network resources and assets from external entities, whether it is hosted on-premises or in the cloud.

Perimeter 81 zero trust platforms are a scalable hardware-free solution that helps organizations provide secure access to their network infrastructure and digital assets including local and cloud resources from end-point to data-center to the cloud. It offers network visibility, resource access segmentation, and full integration with major cloud providers, giving organizations peace of mind in the cloud.

Who is it recommended for?

This service is a good choice for any size of organization but it is a particularly good option for small businesses that don’t have their own technicians on the payroll. The system is easy to sign up to, install, and set up. You need at least 10 users to get a plan.

It offers flexible payment plans with billing occurring on a yearly or monthly basis. When you sign up with Perimeter 81, you get a full management platform where you can build, manage, and secure your network. Get access to a free demo.

BEST ZERO-TRUST SECURITY VENDOR:Perimeter 81is our top choice! Ideal for SMBs, especially those looking for a modern alternative to traditional corporate VPN systems.

2. Twingate

Twingate is a relatively young but fast-rising cloud-based ZTNA service provider. Twingate enables organizations to implement a modern zero-trust network without changing existing infrastructure, and centrally manage user access to company digital assets, whether they are on-premises or in the cloud. Twingate ZTNA solution is offered as an SDP service or an alternative to a traditional VPN. It is delivered as a cloud-based service, and delegates user authentication to a third-party Identity Provider (IdP).

No special technical knowledge is required from end-users other than to download and install the SDP client application and authenticate with an existing identity provider. The controller handles the rest, negotiating encrypted connections between clients and resources. Once everything is confirmed, users are routed to the appropriate resources.

Key Features:

• Hosted in the cloud
• VPN-based
• Free plan

Why do we recommend it?

While Twingate says that its product replaces a VPN, in reality, it is an extended VPN. The extension that it provides is application access controls, which makes this a similar service to NordLayer and Perimeter 81. All user application access goes through the Twingate cloud server for authentication.

The Twingate zero trust architecture relies on four components: Controller, Clients, Connectors, and Relays. These components work in tandem to ensure that only authenticated users gain access to the resources that they have been authorized to access.

Who is it recommended for?

Twingate protects applications running on your premises and in the cloud. Access to all applications is guarded by a menu of services granted to each user. If a user isn’t allowed access to a resource, that software doesn’t even appear in that person’s menu and so, effectively it doesn’t exist for them.

ZERO TRUST:Twingate is a ZTNA that allows businesses to manage remote access to apps and other resources. It comes with a 14-day money-back guarantee.

3. NordLayer

NordLayer operates like a VPN with integrated access rights management. Each user gets an access app that, thanks to a single sign-on mechanism, flows through login actions to each of the applications to which the user is allocated rights.

Key Features:

• VPN-linked
• Remote access
• Access controls
• Single sign-on

Why do we recommend it?

NordLayer is a similar system to Perimeter 81. This is an expansion of the service offered by NordVPN, building application access controls into the VPN client app. The tool can be deployed on mobile devices as well as computers. When users connect to an application, the request passes through the central NordLayer server for approval.

The user app can be assigned to each user whether they are remote or on site. The users only know about the existence of the applications to which they have been granted access and so have no way of even reaching the login screen of the business’s other services. Access to all company sites is blocked from all access other than connections that arrive through one of the authorized NordLayer tunnels.

NordLayer is a package of modules and you decide on your security strategy, whether it is ZTA or a virtual network configuration, such as a SASE. An anti-virus service, called ThreatBlock is included in all plans and you can get FWaaS by adding on the dedicated IP address option.

Who is it recommended for?

As with the Perimeter 81 package, the NordLayer system is suitable for any size of business but especially small enterprises. The minimum user number of an account with this SaaS package is five, so NordLayer caters to even smaller businesses than those that can get the Perimeter 81 service.

RELIABLE ALL-ROUNDER:Small Enterprise Favourite NordLayer is offered in three plan levels and the top two of these can implement ZTA. Get a demo to assess the NordLayer system.

4. ThreatLocker (ACCESS FREE DEMO)

ThreatLocker is a SaaS package, based in the cloud. It provides the building blocks of a ZTA network that can be administered from a console that is hosted on the ThreatLocker server. The controller can manage resources and users in multiple locations and it can control application usage and activity on the cloud as well as those hosted on a site.

Key Features:

• Default block on software
• Allowlisting
• Protects data

Why do we recommend it?

ThreatLocker provides you with a method to protect data and control access to applications. All software on an endpoint in disabled and even new packages won’t run. Files are ringfenced so they can only be accessed by specific applications. Users are granted access to those applications and that software is specifically allowed to run. All other software, including malware, continues to be disabled.

Modules include Allowlisting, which blocks all software from running on owned computers. Only those packages that are on the “allow list” will be able to execute.  The Application Fencing module implements micro-segmentation, controlling access to specific resources, such as directories or files, and logging all activity. A Network Access Control module checks the security of each device before allowing it to connect to the network and controls which servers that endpoint can access. The Storage Control module blocks USB ports that can be activated for the deployment of a specific memory stick by a specific user. This permission can be revoked and all activity is logged.

Who is it recommended for?

The “allowlisting” strategy of ThreatLocker is very easy to administer and it removes all possibility of administrator forgetfulness allowing malware to get access. All software is blocked from running and it takes a specific permission action by the administrator to allow a package to run. Thus, an oversight in administration results in inconvenience rather than a data breach.

All of the logging features in ThreatLocker can be used for threat hunting with a SIEM tool and they are also available for compliance reporting for PCI DSS, HIPAA, and GDPR. One shortfall with the ThreatLocker system is that it doesn’t have its own integrated access rights manager. You can assess ThreatLocker by accessing a demo.

7. Illumio Core & Endpoint

Illumio delivers zero trust micro-segmentation from endpoints to data centers to the cloud to halt cyber-attacks and the spread of ransomware. You can also use Illumio’s zero-trust platform to protect against lateral movements across devices, applications, workloads, servers, and other infrastructure.

Key Features:

• Protection for hybrid networks
• Cloud workload protection
• Servers, cloud platforms, and containers

Why do we recommend it?

Illumio controls the supporting platform for applications and uses that position to block or allow access to applications. The Illumio Core package operates on systems running on your own servers and on the cloud, while Illumio Endpoint, tracks all activity from a specific device.

Illumio zero zero-trust solution is offered via the following platforms:

• Illumio Core (formerly known as Illumio ASP) Delivers visibility and segmentation for workloads and containers in data centers, private clouds, and all public cloud environments.
• Illumio Endpoint (formerly known as Illumio Edge) Brings zero trust to the endpoint and helps prevent the peer-to-peer spread of ransomware and other malware.

Who is it recommended for?

The Illumio services will appeal to different audiences. The Illumio Endpoint service is a little like a User and Entity Behavior analytics service with preventative controls that look a lot like access control lists (ACL) for classic network segmentation. Illumio Core implements network segmentation that extends out across internet connections to cloud services.

With capabilities that span micro-segmentation, network visibility, encryption, and vulnerability management, Illumio’s zero-trust platform provides opportunities for organizations to embrace and implement zero-trust strategies. Pricing details can be obtained by directly contacting the vendor. However, the vendor provides a means to obtain a total cost of ownership (TCO) estimate for Illumio Core to help you build a business case for the elimination of unnecessary hardware in your data center.

8. Absolute ZTNA

The Absolute zero trust solution combines ZTNA, SDP, and enterprise VPN solutions to provide organizations with 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 Absolute platform is to implement it as a service.

Key Features:

• Network segmentation
• IoT access controls
• Application protection

Why do we recommend it?

Absolute ZTNA provides both network security and protection for applications. The tool is particularly useful for securing access for potentially insecure devices, such as IoT devices or BYOD equipment. As well as Zero Trust Network Access, the package implements Zero Trust Access for application access.

The Absolute 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 Absolute 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.

Who is it recommended for?

This package is primarily a network security service and it also implements application security. The tool authenticates the user that wants access to corporate resources and also validates the security of the device that the request comes from. This device security scanning is particularly important for IoT devices that don’t involve the use of access credentials.

You can examine the Absolute ZTNA platform by accessing a demo.

9. Appgate

Appgate ZTNA solution is offered as software-defined perimeter, VPN alternative, secure third party, and DevOps access based on zero trust principles and built to support hybrid IT and a distributed workforce. It is infrastructure agnostic and can be deployed in all environments: on-premises, multi-cloud (AWS, Azure, GPC), virtualized containerized environments, and legacy networks and infrastructure.

Appgate was named a leader in the Forrester Zero Trust New Wave 2021 report. The entire Appgate ZTNA solution is designed to be distributed and to offer high availability, and it can be deployed in physical, cloud, or virtual environments. The Appgate platform integrates seamlessly with third-party applications such as IdPs, LDAP, MFA, and SIEM, among others.

Key Features:

• Network security
• Appliance based
• Software-defined perimeter

Why do we recommend it?

The Appgate system provides a software-defined perimeter, however, it is delivered on an appliance. The appliance implements all of the security management for the network, which is delivered after an assessment of the user trying to get into the system and the device of the user. The device must be free of malware and other security risks and the user must present the right credentials.

With the Appgate ZTNA solution, access can be controlled from any location and to any enterprise resource with centralized policy management for servers, desktops, mobile devices, and cloud infrastructure among others.

The Appgate ZTNA platform consists of three main components:

• Controller The controller manages user authentication and applies access policies assigned to users based on user attributes, roles, and context. It then issues entitlement tokens listing the resources the user is permitted to access.
• Client The Appgate client is software that runs on user devices, and connects with Appgate appliances to receive site-based entitlement tokens after successful authentication.
• Gateway The gateway evaluates user entitlements and opens connections to resources accordingly.

Who is it recommended for?

Appgate is similar to the Absolute ZTNA system because it implements network access controls for potentially insecure devices, such as IoT equipment and BYOD. The service can also be used to control access to applications, in which case, it provides a ZTA service.

The Appgate SDP (part of its ZTNA solution) is available for a test drive, and the virtual appliances and client software are also available for download.
