5. Foxpass: Lightweight RADIUS for Smaller Environments
G2 Rating: 4.6/5 (60 Reviews)
Foxpass is a cloud-based RADIUS solution focused on simplicity and ease of deployment. Foxpass services typically use EAP-TTLS/PAP for authentication. It is an outdated protocol that does not use encryption for user authentication and transmits credentials as plain text, making them highly susceptible to cyber-attacks.
Foxpass also supports the PEAP-MSCHAPV2 protocol, which heavily depends on credentials and has known vulnerabilities. PEAP uses a modified TLS handshake and MSCHAPv2 to authenticate credentials. It is often used by smaller organizations or teams that need a basic RADIUS setup without complex infrastructure.
While Foxpass covers all market segments, reviews suggest mid-market enterprises comprise the largest share of customers. Foxpass allows users to define their own rules for multiple operating systems using pre-configured LDAP protocol and enables users to use the same Foxpass credentials for Wi-Fi or LAN networks.
Most customers felt that implementing LDAP and RADIUS services was hassle-free with Google Workspace and other similar applications. They were also satisfied with the customer support’s response and felt Foxpass simplified the entire authentication process. Additionally, customers found that Foxpass integrated well with different SaaS directories.
While it provides essential functionality, Foxpass lacks the automation, scalability, and advanced security features that enterprise environments require.

How To Choose the Best RADIUS Server
Today, there are numerous cloud RADIUS services available to enterprises. For an already-busy network administrator, choosing the right one can be confusing and overwhelming. As you consider your options, keep these RADIUS server requirements in mind:
- Scope
- Environment
- Internal Time Commitment and Expertise
- Regulatory Compliance Requirements
- Integration and Ease of Deployment
- Compatible Authentication Methods and Security Features
- Support and Documentation
- Regular Updates
- Budget
- Scalability
Scope
How many users and devices do you manage? What access controls do you require? Do you need network authentication for wired, wireless, or VPN connections — or all of the above? How important is accounting support?
Get a clear picture of the scope of your RADIUS needs before comparing solutions.
Environment
Do you have the resources necessary to manage on-prem infrastructure, or do you prefer a cloud-based RADIUS solution? There’s no single right answer — it depends on your business, facilities, staff, and budget.
Internal Time Commitment and Expertise
Do you want a managed service provider to set up, implement, onboard, and maintain your server? If not, you’ll need to handle implementation and management in-house, which requires niche expertise and internal resources.
Regulatory Compliance Requirements
For managed solutions, not all RADIUS providers offer the same built-in compliance. Identify your needs and compare solutions.
Integration and Ease of Deployment
Ideally, any enterprise RADIUS server you use should be able to integrate with your existing infrastructural components. Having to make any huge changes or forklift upgrades to your infrastructure will just draw out the length of deployment — leaving your network vulnerable for an even longer amount of time.
Look for information about which identity providers and Wi-Fi vendors integrate with the RADIUS. Make sure that the list includes your infrastructure vendors.
Compatible Authentication Methods and Security Features
Consider what type of authentication you want to use along with your RADIUS. Many organizations still use credentials, which most RADIUS servers support.
However, digital certificates offer vastly superior security, and deployment is simple with a good managed PKI service. If you’re interested in this route, you will need to ensure your RADIUS server is compatible with digital certificates.
You’ll also want to think about the authentication protocols supported by each RADIUS service’s infrastructure. This is often related to whether you’ll be using certificates or passwords. We recommend EAP-TLS given its speed and compatibility with digital certificates. However, not all RADIUS services are guaranteed to support it in their standard service. Alternatively, they may support protocols like PEAP-MSCHAPv2, which encrypt credentials.
Don’t forget to evaluate directory support. For example, if you use Active Directory, EAP-TTLS/PAP won’t support it. Finally, if you want other security features such as multi-factor authentication (MFA), verify that they’re compatible with your RADIUS solution.
Support and Documentation
RADIUS servers require expertise to set up and maintain on a day-to-day basis. Having detailed supporting documentation will give you the resources you need to reference in the future if any issues arise.
The addition of a support team is even better. Who better to help you quickly resolve issues than the people who built the RADIUS and work with it every day? Not all RADIUS services offer the same amount of support, though, so this is something to keep in mind while you look at your options.
Regular Updates
Any security-conscious professional knows that your security measures must adapt to keep up with emerging threats. Similarly, any RADIUS service you utilize should also evolve to keep up with the times.
Vigilant RADIUS services often develop and release new features. Examples recent additions to some services include features like RadSec or Change of Authorization.
Budget
What are you willing to invest in the right RADIUS authentication software? In addition to basic implementation and recurring costs, consider the return on investment (ROI) of each solution: the potential time and cost savings relative to the features offered.
Scalability
While most RADIUS solutions are inherently flexible and scalable, it’s still a critical detail to verify.
What’s your business growth plan over the next three, five, or 10 years? While the best RADIUS solution should accommodate your current needs, it also must scale as your organization expands.
Best RADIUS Servers for Enterprise
Cloud Infrastructure
Passwordless
Cloud RADIUS is a managed RADIUS service that offers secure, passwordless authentication with digital certificates. It pairs with the JoinNow Dynamic PKI and easy onboarding and deployment tools, such as the SecureW2 MultiOS dissolvable onboarding client and managed device gateways.
Cloud RADIUS is known for its vendor-neutrality and ability to seamlessly fit into any infrastructure. With its supporting team of engineers, it can be deployed in under an hour.
What’s more, Cloud RADIUS empowers organizations to move past legacy protocols like LDAP. Since it can communicate directly with your identity provider (IdP) at the time of authentication, you don’t need a duplicate LDAP directory server. Without ties to legacy protocols, Cloud RADIUS makes it simple for enterprises to move to the cloud for all their authentication needs.
Password and LDAP-Based
There are many cloud RADIUS servers available that utilize LDAP today. Many of them have attractive features, such as free trials of varying lengths that allow your administrators to get a feel for how they work prior to large-scale deployment.
Some have additional perks, too, such as multi-tenant portals for MSPS or the ability to integrate with major IdPs. A common drawback of these types of RADIUS servers is their reliance on cloud LDAP servers rather than direct communication with your IdP. Unfortunately, there are plenty of reasons for organizations to steer away from LDAP these days.
Additionally, many of these services aren’t designed for passwordless authentication by default. The main authentication protocol they tend to support is EAP-TTLS/PAP. This doesn’t mean that you can’t go passwordless with such services, but some require you to purchase an add-on to do so with EAP-TLS.
Which Is Better: RADIUS or LDAP?
RADIUS helps regulate network access across wired, Wi-Fi, and VPN connections. On-premise or cloud-based, it can authenticate, authorize, and provide accounting support (AAA) via passwordless certificate-based authentication or user credentials. RADIUS runs on User Datagram Protocol (UDP), which is efficient, but doesn’t require a confirmed connection to transmit data packets.
Lightweight Directory Access Protocol (LDAP) is an authentication protocol like RADIUS. It’s typically on-prem only without cloud options, and while it can authenticate and authorize users, it doesn’t have accounting support. LDAP runs on Transport Layer Security (TLS). It doesn’t secure credentials to the same degree as RADIUS, and it doesn’t support passwordless (certificate-based) authentication.
If you’re deciding between LDAP vs. RADIUS, RADIUS is a more flexible, robust, and secure option.
Open Source
In terms of monetary expenditure, open-source RADIUS servers are a noteworthy option. Since they are open source, they are generally readily available, and you don’t have to pay licensing fees.
But like many other “free” things, open-source RADIUS servers are an entirely unmanaged service. You will need to configure it and deploy it yourself within your organization. Furthermore, it may not include any access to a support team by default, although some open-source RADIUS servers may offer additional support for a variable price.
Legacy and On-Premise
For some organizations, on-prem RADIUS servers are the preferred choice. This could be the case, for example, if you’ve already set up the necessary infrastructure for one in the past or you only have one office location to worry about.
But in many other situations, cloud-based RADIUS services are a far superior choice. They don’t require replication across multiple locations, they’re generally simple to deploy, and you don’t have to invest in physical security measures to protect them from local weather conditions or threats.
