FreeRADIUS vs OneRADIUS — Complete Comparison 2026

Choosing the right RADIUS server is one of the most critical infrastructure decisions an ISP can make. Your AAA (Authentication, Authorization, and Accounting) platform sits at the heart of your network — controlling who gets online, for how long, at what speed, and how billing gets calculated. In 2026, two names dominate the conversation for ISPs in India: FreeRADIUS and OneRADIUS.

FreeRADIUS is the world's most widely deployed open-source RADIUS server. OneRADIUS, built by ARCR Technologies in Hyderabad, is a purpose-built commercial AAA RADIUS platform designed specifically for the needs of Indian ISPs and broadband operators.

In this detailed comparison, we break down everything — from features and performance to support, compliance, and total cost of ownership — so you can make a fully informed decision.

What Is FreeRADIUS?

FreeRADIUS is an open-source, highly configurable RADIUS server that has been around since 1999. It supports virtually every RADIUS extension and authentication protocol known to exist. It is free to download, free to use, and backed by a global community of developers.

However, 'free' does not mean 'zero cost.' FreeRADIUS requires significant technical expertise to install, configure, harden, and maintain. For ISPs without a dedicated team of Linux and RADIUS engineers, FreeRADIUS can become a liability rather than an asset.

Key Characteristics of FreeRADIUS

  • Open-source under GPLv2 licence
  • Runs on Linux/Unix environments
  • Highly extensible via modules and scripts
  • Supports PAP, CHAP, MS-CHAP, EAP, TTLS, PEAP and more
  • No native GUI — managed entirely via configuration files
  • Community support via mailing lists and forums
  • Requires manual integration with billing systems
  • No built-in Indian ISP compliance features

FreeRADIUS vs OneRADIUS — Feature-by-Feature Comparison

1. Installation and Setup

FreeRADIUS:

Installing FreeRADIUS from scratch requires command-line Linux skills, manual configuration of SQL backends (MySQL/PostgreSQL), and careful module-level configuration. For a basic PPPoE setup alone, a skilled engineer may need several days. Advanced configurations — like CoA, dynamic VLAN, or Disconnect Messages — can take weeks to get right.

OneRADIUS:

OneRADIUS is delivered with a guided installation process and a web-based setup wizard. ARCR Technologies provides hands-on onboarding support, meaning most ISPs are fully operational within hours of deployment. NAS devices, plans, and users can all be configured from a centralised dashboard without touching a single config file.

💡 OneRADIUS is ideal for ISPs who want to go live quickly without needing a full-time RADIUS engineer on staff.

2. User Interface

FreeRADIUS:

FreeRADIUS has no native GUI. Administrators interact with it through text-based configuration files located across multiple directories. Third-party frontends like daloRADIUS or phpIPAM can be added, but they are separate projects with their own bugs, limited support, and steep learning curves.

OneRADIUS:

OneRADIUS ships with a fully integrated, modern web-based GUI. Operators can manage subscribers, plans, NAS devices, resellers, invoices, and reports — all from a single dashboard. Role-based access control allows different staff members (admin, support, billing) to have appropriate access levels.

💡 The OneRADIUS GUI is designed to be usable by non-technical staff, reducing your dependency on engineers for day-to-day operations.

3. Authentication Protocols Supported

FreeRADIUS:

  • PAP, CHAP, MS-CHAPv2
  • EAP (all major variants)
  • TTLS, PEAP, TLS
  • DIGEST-MD5, SIP authentication
  • Fully extensible with custom modules

OneRADIUS:

  • PAP, CHAP, MS-CHAPv2
  • EAP support
  • PPPoE authentication (NAS-level)
  • IPoE / MAC-based authentication
  • Hotspot / Captive portal authentication
  • Custom authentication policies

Both platforms support the core protocols needed for Indian ISP environments. FreeRADIUS has a broader raw protocol list, but OneRADIUS covers everything a broadband ISP actually needs in practice.

4. Billing and Plan Management

FreeRADIUS:

FreeRADIUS has no billing engine whatsoever. To build a billing system around FreeRADIUS, you need to integrate it with a third-party billing platform (like Powercode, Sonar, or a custom-built solution). This integration requires development work, ongoing maintenance, and careful synchronisation to avoid billing errors.

OneRADIUS:

OneRADIUS includes a built-in billing engine that handles:

  • **Prepaid plans** with data and time quotas
  • **Postpaid plans** with monthly billing cycles
  • **FUP (Fair Usage Policy)** with automatic speed reduction after threshold
  • **Plan upgrades and downgrades** mid-cycle
  • **Grace periods** and automatic account suspension
  • **Invoice generation** and payment tracking
  • **SMS and email alerts** for expiry and low balance
💡 The integrated billing in OneRADIUS eliminates the risk of synchronisation failures between your RADIUS server and billing system — a common pain point with FreeRADIUS deployments.

5. Multi-NAS and Multi-Location Support

FreeRADIUS:

FreeRADIUS can support multiple NAS devices, but configuration must be done manually for each device in the clients.conf file. Managing hundreds of NAS devices across locations requires scripting, automation tools, or third-party management software.

OneRADIUS:

OneRADIUS provides a dedicated NAS management interface where you can add, edit, and monitor multiple NAS devices across different cities or zones. Each NAS can have its own configuration, and dynamic CoA (Change of Authorisation) messages are sent automatically when subscriber plans change.

6. Reseller and Franchise Management

FreeRADIUS:

No native reseller management. This must be built entirely from scratch using scripts and database customisation.

OneRADIUS:

OneRADIUS includes a multi-level reseller module allowing ISPs to onboard sub-distributors, LCOs (Local Cable Operators), and franchise partners. Each reseller gets their own login, their own subscriber management interface, and their own plan catalogue. The parent ISP retains full visibility and control over the entire hierarchy.

💡 The reseller module in OneRADIUS is one of its most powerful differentiators for Indian ISPs who work with LCOs and franchise networks.

7. TRAI and DOT Compliance

FreeRADIUS:

FreeRADIUS has no awareness of Indian regulatory requirements. ISPs must build their own compliance features — including CDR (Call Detail Record) generation, data logging for lawful interception, and user verification workflows.

OneRADIUS:

OneRADIUS is built with Indian ISP regulatory compliance in mind. It supports:

  • Accurate CDR and session log generation
  • Subscriber data management per DOT guidelines
  • Audit trails and data retention policies
  • Compatibility with lawful interception requirements
⚠️ Failing to meet TRAI and DOT compliance requirements can result in licence penalties or suspension. OneRADIUS reduces this risk significantly by having compliance features built in.

8. Dynamic Bandwidth Control and CoA

FreeRADIUS:

FreeRADIUS supports CoA (RFC 3576) and can send Disconnect Messages or change session attributes dynamically. However, setting this up requires deep expertise in RADIUS packet crafting and NAS-specific quirks. FUP logic must be built using external scripts and cron jobs.

OneRADIUS:

OneRADIUS handles dynamic bandwidth control natively. When a subscriber reaches their FUP threshold, the system automatically:

  • Calculates the new speed profile
  • Sends a CoA message to the NAS
  • Updates the subscriber record
  • Notifies the subscriber via SMS or email

No scripting required. Everything is configured from the GUI in minutes.

9. Reporting and Analytics

FreeRADIUS:

FreeRADIUS logs data to SQL tables. To get any meaningful reports, you need to build your own queries, dashboards, or integrate a BI tool like Grafana or Kibana. This is powerful for technically advanced teams but impractical for most ISPs.

OneRADIUS:

OneRADIUS includes a built-in reporting module with:

  • **Active session monitoring** in real time
  • **Subscriber usage reports** (daily, weekly, monthly)
  • **Revenue and billing reports**
  • **NAS health and uptime reports**
  • **Plan-wise subscriber distribution**
  • **Reseller performance reports**

All reports are exportable to PDF or Excel for business use.

10. High Availability and Scalability

FreeRADIUS:

FreeRADIUS can be clustered for high availability, but this requires setting up proxy configurations, load balancers, and database replication manually. For large ISPs, this is achievable but demands significant DevOps expertise.

OneRADIUS:

OneRADIUS is architected to handle high subscriber loads. ARCR Technologies provides deployment guidance for HA configurations suited to your subscriber base size. The platform is actively used by ISPs managing large networks across India.

11. Support and SLA

FreeRADIUS:

Support is community-based — mailing lists, IRC/forums, and Stack Overflow. Commercial support contracts are available through a limited number of third-party vendors. Response times are unpredictable. If your network goes down at 2 AM, there is no SLA.

OneRADIUS:

OneRADIUS is backed by ARCR Technologies' dedicated support team based in Hyderabad. Support is available via phone, email, and remote access. SLA-based support plans ensure that critical issues are addressed promptly — a must-have for ISPs where downtime directly means subscriber churn and revenue loss.

⚠️ For a production ISP network, relying on community forums for RADIUS support is a serious operational risk. A single misconfiguration can disconnect thousands of subscribers.

12. Total Cost of Ownership (TCO)

FreeRADIUS:

While the software itself is free, the true cost of FreeRADIUS includes:

  • Hiring or training engineers with RADIUS and Linux expertise
  • Development time for billing integration
  • Development time for GUI/reporting tools
  • Ongoing maintenance and patching
  • Lost productivity from troubleshooting
  • Potential downtime costs

For most small and mid-size ISPs, FreeRADIUS 'free' software ends up costing far more in human resources than a commercial solution.

OneRADIUS:

OneRADIUS has a clear, transparent licensing cost. What you pay is what you get — fully functional software, ongoing updates, and professional support. The total cost of ownership is typically lower than FreeRADIUS when you factor in reduced engineering overhead, faster deployment, and avoided downtime.

Real-World ISP Perspective: The Hidden Costs of FreeRADIUS

Many ISPs start with FreeRADIUS because it is free. Here is a typical journey:

  1. Download and install FreeRADIUS — takes a few days with tutorials
  2. Integrate MySQL for subscriber data — another few days
  3. Configure PPPoE authentication — working after a week
  4. Need FUP? Write shell scripts. Need billing? Build a system. Need resellers? More development.
  5. 6 months later, the 'free' RADIUS server has consumed hundreds of engineer-hours
  6. A production outage occurs — no support, frantic community forum posts at midnight
  7. Eventually migrate to a commercial solution anyway

This is a pattern ARCR Technologies has seen repeatedly. OneRADIUS was built precisely to shortcut this painful journey and give Indian ISPs an enterprise-ready platform from day one.

OneRADIUS Unique Advantages for Indian ISPs in 2026

Built for Indian Network Topologies

Indian broadband networks have unique characteristics — mixed PPPoE and IPoE deployments, legacy BSNL infrastructure integration, a massive LCO ecosystem, and diverse NAS hardware from vendors like MikroTik, Cisco, Juniper, and Huawei. OneRADIUS is tested and optimised for this exact environment.

Vernacular and Local Support

ARCR Technologies provides support in English and local languages, making it easier for regional ISP operators across India to communicate issues clearly and get them resolved faster.

Continuous Updates for Indian Regulations

As TRAI and DOT update their guidelines, OneRADIUS is updated to maintain compliance. FreeRADIUS, being a global open-source project, has no mechanism for tracking Indian regulatory changes.

MikroTik and Local Hardware Optimisation

A large proportion of Indian ISPs use MikroTik routers as NAS devices. OneRADIUS is specifically optimised for MikroTik RADIUS attributes, CoA behaviour, and PPPoE profile management — something that requires significant manual work in FreeRADIUS.

💡 If your network runs on MikroTik, OneRADIUS delivers a significantly smoother experience out of the box compared to FreeRADIUS.

---

Migration from FreeRADIUS to OneRADIUS

If you are currently running FreeRADIUS and considering a switch to OneRADIUS, the migration process is well-supported by ARCR Technologies. Key steps include:

  • **Subscriber data migration** from your existing SQL database to OneRADIUS
  • **Plan and policy recreation** in the OneRADIUS billing engine
  • **NAS reconfiguration** to point to the new RADIUS server
  • **Parallel running** during transition to ensure zero downtime
  • **Testing and go-live** with full ARCR support
⚠️ Never do a hard cutover from FreeRADIUS to any new RADIUS server without a parallel testing period. Even a 5-minute authentication outage during peak hours can disconnect thousands of subscribers.
