Scale your ISP to
Millions of Users
With the architects of the best RADIUS server for ISPs.
Your subscriber base is growing.
But your network infrastructure is holding you back.
Do you have the best RADIUS server for ISPs? Or are you running software that wasn’t designed for scale?
Licensing costs spiral out of control.
Commercial RADIUS products charge $15-45 per user annually. At 100,000 subscribers, that's $1.5 to 4.5 million per year.
Billing queries slow authentication to a crawl.
When Accounting and Authentication share databases, monthly billing reports block user logins.
Single-site deployments create downtime risk.
Credential sharing costs you revenue.
Enterprise RADIUS doesn't scale.
We deliver the best RADIUS server for ISPs and
architecture expertise that you need to grow.

CASE STUDY
RADIUS proxy consolidation for efficiency
This ISP was managing multiple RADIUS proxy servers across their network, creating operational overhead and increasing costs.
InkBridge consolidated their proxy infrastructure, reducing complexity whilst maintaining multi-site redundancy.
The streamlined architecture cut management time and operational expenses while improving system reliability.

CASE STUDY
Slow SQL server performance
An ISP's authentication system was struggling with database performance issues.
Instead of expensive hardware upgrades, InkBridge optimized their database architecture and query patterns, reducing database load by 400x.
The result: dramatically faster authentication response times using existing infrastructure, saving both time and capital expenditure.

Ready to scale your ISP authentication?
We’ve designed solutions for ISPs worldwide. Let’s discuss your needs for new deployments or upgrades.
Frequently asked questions
Yes. National ISPs authenticate 10–20 million users on FreeRADIUS deployments. It's the most widely deployed RADIUS server globally, handling 100+ million daily authentications. Scale is proven.
FreeRADIUS is the open-source RADIUS server. InkBridgeRADIUS is our productized solution with enterprise features, monitoring tools, templating for multi-site management, and commercial support. Both avoid per-user licensing.
Small ISP deployments: 2-4 weeks. Multi-site regional ISPs: 4-8 weeks. National-scale implementations: 8-12 weeks. Timeline depends on your existing infrastructure and integration complexity.
Yes. We've migrated numerous ISPs from commercial RADIUS products. We assess your current configuration, design the new architecture, handle data migration, and provide parallel testing before cutover to minimize risk.
24/7 support for critical issues, configuration reviews, performance optimization, capacity planning, and custom development for billing integrations or unique requirements. Support is tailored to ISP operational needs.
