Why ISPs choose SudoRadius

Everything you need to connect and bill subscribers — run for you.

Stop maintaining RADIUS servers, databases and certificates. Sign up, point your network at us, and get back to growing your customer base.

Private by default

Your customers are yours alone

Every ISP on SudoRadius is completely walled off from the next. Your subscribers, plans, usage and credentials are isolated and encrypted — no other operator can ever see or touch them, and neither can we without your keys.

Any device

Works with the gear you already run

Point any router, BNG, access point or firewall at SudoRadius — modern or legacy. If it speaks RADIUS, it works, securely.

More revenue

Sell the plans customers want

Prepaid data and time bundles, uncapped plans, fair-use speeds and top-ups — applied the instant a customer hits a limit.

Hotspots

Turn Wi-Fi into income

Run paid hotspots with vouchers and a login page. Your resellers keep the payments; we handle the access and time limits.

Peace of mind

Always on, always nearby

Carrier-grade uptime with a local presence in your region, so subscribers connect fast and their data stays in your country.

Connects to your billing

It fits the tools you already use

SudoRadius keeps your billing system in sync automatically — it knows the moment a customer signs up, runs low on data, or finishes a session, so you can invoice accurately without lifting a finger.

How it works

From signup to an authenticating subscriber in three steps.

Create your account

Sign up and your own private ISP space is ready in seconds — your login, your plans, and the connection details for your network. No tickets, no servers to set up.

Connect your network

Point your routers and access points at your private SudoRadius address, then add your subscribers — by hand in the console, or straight from your billing system.

Customers connect & you get paid

Subscribers come online and their plans, caps and speeds apply automatically. Every session and data total flows to your billing, so invoicing just works.

Grows with you

From your first customer to your hundred-thousandth.

  • Start in minutes, pay as you grow. Begin on shared infrastructure and add capacity only when your subscriber base needs it.
  • Dedicated when it matters. Move a busy network to its own dedicated capacity in one click — no migration, no downtime, no noisy neighbours.
  • Close to your customers. Choose where your network lives — South Africa, Europe or the US — so logins are fast and latency is low.
  • Compliant by location. Your subscribers' data stays in your chosen country, helping you meet POPIA and GDPR.

Connects to your systems

Already have a billing system? It just plugs in.

Manage subscribers, change plans and read usage from your own software with a simple, secure API — or do it all by hand in the console. Whatever suits your team.

example
add a subscriber
# add a customer to your network from your billing system
curl -X POST https://api.radius.ip4x.systems/v1/subscribers \
  -H "Authorization: Bearer your-api-key" \
  -d '{
    "username": "thandi@karoo",
    "password": "•••••••",
    "plan": "50GB Fibre"
  }'

# usage, sessions & alerts flow back to you automatically
