Many employees and contractors work offsite in home networks, coffee shops, hotels, and other untrusted networks. Meanwhile, many cloud applications and data repositories have also migrated outside of the centralized control of an organization’s IT environment.

IT managers seek to protect these users, devices and resources by moving the IT perimeter and rerouting all data through corporate control to prevent unauthorized access. One method to accomplish this goal is to use zero trust.

There are many zero trust solutions addressing the five key categories of Zero Trust Architecture (ZTA): 

• Identity
• Devices
• Networks
• Data
• Applications and Workloads

However, for most organizations limitations of budgets and IT team bandwidth will force selective adoption of ZTA and a focus on solutions that can be implemented quickly, inexpensively, and comprehensively with minimal expense. Zero Trust Network Access (ZTNA) will likely be one of the easiest methods for an organization to begin to adopt ZTA so we will focus on the top low-cost turnkey ZTNA products.

This list is aimed more at small and mid-sized businesses (SMBs) seeking low-cost, easy to implement solutions, so larger enterprises might want to see our list of Top Zero Trust Security Solutions & Software.

Jump ahead to the top low-cost zero trust solutions:

• Appaegis
• Banyan Security
• Cloudflare
• GoodAccess
• NordLayer
• OpenVPN
• Perimeter 81
• Zentry Sentry
• Other zero trust solutions

What is Zero Trust?

The basic concepts behind ZTA were developed by Forrester Research and require an organization to treat all resources as if they are fully exposed to the internet. No users may be trusted by default, all users should be restricted to the minimum access needed, and fully comprehensive monitoring should be in place.

The firewalls and hardened security layers that used to exist only at the access point to a network now must be shifted and implemented for each endpoint, server, container, and even application. Each access request and session must start with the assumption that the user and device may be compromised and requires fresh verification.

U.S. Government agencies have received requirements to achieve zero trust security goals and many corporate executives also seek to improve their security and compliance using zero trust architecture.

Zero Trust does not require new tools or technologies to implement. Operating systems, firewalls, and other tools can be implemented on a device-by-device or application-by-application basis to implement zero trust.

However, new ZTA-branded tools often simplify the process for IT managers to implement. Instead of a variety of different tools with overlapping or even conflicting rules, ZTA tools provide a single place to implement policies and then push those policies out to linked technologies.

IT managers define what applications, databases, servers, and networks will be available to the end user from a central management console. However, keep in mind that to implement ZTA, companies must be ready to granularly differentiate between users and devices.

Any organization that does not use the features of ZTA to provide minimum needed access simply has recreated a non-ZTA trusted network with more expensive technology.

Note: We’ve included a glossary of key zero trust terms at the bottom of this article if any need clarification. 

Top Low-Cost Zero Trust Product Criteria

We reviewed many different vendors for this article and zero trust is too broad to compare or cover them all in a single article. To make this list of the top low-cost zero trust options we focused on a limited set of criteria that could provide value to the broadest range of organizations.

Vendors that made this list provide a solution that could be started very quickly, with minimal IT labor, and with no internal installation required. We focused on turn-key SaaS solutions that an IT manager could implement in a matter of hours and deploy to the entire organization.

These Zero Trust Network Access (ZTNA) products must replace or complement Virtual Private Network (VPN) access and publicly list their pricing for comparison. While many companies may offer free trials or tiers, we only list vendors that have a cost below $ 15 / user per month for their basic paid tier of service.

These solutions also must provide fully encrypted connections and support multi-factor authentication. These solutions should also support access to legacy IT infrastructure.

Types of Zero Trust Network Access Providers

ZTNA can be accomplished in many different ways, but a turnkey solution tends to be offered either as a browser-based solution or a global edge network solution.

Browser Based Solutions

These companies accomplish the practical equivalent of ZTNA through a secure browser. End users download the browser to their local endpoint and must use it to access corporate resources. The vendor also provides a cloud-based app that allows the IT manager to add and manage users and corporate resources in a single software package.

Global Edge Network Solutions

Vendors in the Global Edge Network category replace existing wired or software-defined network infrastructure with a cloud-based equivalent software-defined network on a subscription basis. The internet provides the wires and the vendor provides encrypted connections between the users and the protected resources.

While the details of deployment may vary, generally an agent or connector will be installed to cloud-based or on-premises resources such as servers, containers, and applications. These connectors create a secure tunnel to a Global Edge Network that can sometimes replace the need for firewall rules or DMZ architectures.

Administrators then use a SaaS management interface to select resources to make available to end users using access policies. Users then connect to the encrypted network through a standard browser or through an app.

Some vendors focus on Secure Web Gateways and others focus on cloud-based VPN Servers, but when delivering ZTNA their offerings tend to combine features of gateways, VPNs, and even CASB. Be sure to review the specific offerings of a vendor to ensure they meet the needed requirements.

Other Zero Trust Vendors

Many other products attempt to fill the Zero Trust Network Access niche with methods to securely connect all workers with all resources. However, there were two types of vendors that we did not consider for this article.

First, some vendors don’t list their prices on their websites so their cost could not be compared with other vendors. Some of these vendors will offer free trials and many will also have technology partners that can help explain features and drawbacks to an interested customer.

The other type of vendor was ZTNA providers that required significant installations and could not be considered turn-key. If the vendor needed cloud computers, dedicated servers, or virtual machines established we considered the threshold too high to be considered for this article.

This does not mean that our recommended vendors are the best solution for a specific organization’s needs. IT managers looking for even more options can consider these additional solutions:

• Akamai Enterprise Application Access provides a cloud-based secure web gateway that delivers real-time intelligence and detection engines to provide multi-layered security.
• Avast Business’ Secure Private Access provides a ZTNA alternative to VPN connections with their cloud-based solution.
• Axis Security’s Atmos product line delivers secure remote access, CASB, DLP, and other features. Different levels of subscriptions include different Atmos licenses to deliver different capabilities.
• Appgate offers a Software Defined Perimeter (SDP) product that provides single packet-level authorization security, microsegmentation, and continuous verification of access. Government pricing is quoted by AWS at roughly $ 12 per day for 25 users or roughly $ 15 per user per month. However, non-government customers need to go through partners and MSP resellers.
• BlackBerry’s CylanceGateway automatically enforces corporate policies across an AI-driven Zero Trust Network that also incorporates endpoint security and granular policy management.
• Cato Networks secure remote access is delivered via their SASE solution. Their solution is unusual because the billing is based upon traffic speed and throughput instead of mainly per-user fees.
• Check Point’s Harmony security solution offers endpoint security, clientless connectivity, VPN remote access, email security, mobile security, and secure internet browsing as a bundle.
• Cyolo provides a Zero Trust platform that supports a wide range of endpoints and cloud applications. It attempts to replace many different legacy tools such as CASB, MFA, ADC, NAC, VPN, and PAM with a unified security and networking tool.
• Google Cloud BeyondCorp provides ZTNA protection for organizations that can establish, secure and manage HTTPS load balancers or virtual machines on Google Cloud. While the costs are competitive with turn-key SaaS solutions, not all organizations have the ability to manage cloud resources.
• Iboss provides a Zero Trust platform that replaces VPN with a solution that delivers SASE, Browser Isolation, CASB, and DLP.
• InstaSafe provides hosted controllers and installable gateways to create fully encrypted channels for authentication and access to cloud resources, applications, and local resources. While reasonably priced at $ 8 / user / month this solution also requires IT teams to install local gateway ($ 35 / month / gateway) which exceeded the technical work required to make our list of solutions.
• Ivanti markets their Neurons as a cloud-based Zero Trust Access solution. Ivanti modules also support asset discovery, operational intelligence, and patch management.
• Jamf’s Wandera product provides private access, threat defense, and enforce data policies.
• NetMotion offers a remote access solution that provides both software defined perimeter (SDP) and VPN connections to cloud-based and local resources. Their solution requires customers to install the software on self-managed local or cloud-hosted servers.
• Netskope offers SSE and SASE zero trust solutions through system integrators and service providers. Pricing for individual components (CASB, etc.) can be located on the web or through the AWS marketplace, but a single price for the zero trust package is not publicly available.
• Proofpoint offers cloud-based security products that deliver Secure Service Edge solutions such as secure access and secure remote access for contractors. 
• RevBits Zero Trust Network provides a thin-client application that fully encrypts user access to corporate resources.
• Broadcom’s Symantec Secure Access Cloud provides a SaaS zero trust access solution to replace VPN technology with agentless, cloud-delivered infrastructure..
• Tempered’s Airwall solution replaces VPNs with an encrypted software defined perimeter (SDP) network. This permits microsegmentation and eliminates VPN congestion issues.
• TerraZone’s ZoneZero creates software defined perimeters that can enhance VPN services to make them zero trust networks.
• Twingate delivers a multi-step authentication process that requires at least two different components to permit communication between users and resources. Twingate’s solution requires deployment of a docker container or native linux service on remote networks which is a bit more work than a turnkey solution.
• TrueFort focuses on zero trust microsegmentation, workload hardening, and file integrity monitoring.
• Trustgrid is a ZTNA platform for application development. Up to 10 users and 25 nodes for $ 1,995 / month ($ 19.95 / user per month). More expensive option, but it allows for docker containers to run and update at the edge without centralized management or architecture.
• Versa Networks launched their cloud-based Secure Access VPN-as-a-service in 2020 with a price of $ 7.50 per user per month. However, current SASE Services do not list prices on the website and require contacting the company or a partner for a quote.
• VMware Horizon offers a digital workspace that can provide ZTNA features. However, this product is designed to integrate with other VMware solutions and does not appear to work as a turn-key solution.
• Zscaler delivers a cloud-based ZTNA solution by routing all traffic through its cloud filters for authorization, inspection, and control. While some pricing can be found in the AWS marketplace, IT managers generally need to contact Zscaler for pricing.

Zero Trust Buying Considerations

As with all IT needs, zero trust can be implemented in many different ways. ZTNA will likely be one of the easiest methods to start adopting zero trust and organizations with constrained resources will seek vendors that provide easy adoption with minimal IT labor for support and implementation.

We analyzed many different ZTNA companies and only eight companies could be verified to provide a low-cost solution that could be implemented quickly. These solutions likely will satisfy the needs of any company with an emergency need or limited resources; however, organizations should investigate their options thoroughly before making a decision.
