Some enterprises still don't use RADIUS for network access control. That's a significant security gap.

RADIUS is the only protocol that secures the network access layer at scale - and it's available in virtually every piece of network equipment on the market. It's backed by decades of standards work through the IETF, with active development still happening today. It's not a legacy protocol on its way out. It's a living standard with serious people behind it.

If your organisation isn't using RADIUS, the question isn't whether you have a security problem. It's how large that problem is.

Scott Shambaugh, the open-source maintainer targeted by a rogue AI agent in February, proposed something compelling: AI agents need something like a licence plate.

A traceable link between agent behaviour and a responsible human, accessible when harm occurs.

Right now, that framework does not exist. Our latest post looks at why it should, and what open-source projects can do in the meantime.

If your IT processes take two weeks to provision a development VM, your developers will spin one up on a personal device instead. A decision of convenience becomes an internal data breach.

AAA security architecture should make the secure option as easy as the insecure workaround. Terry Burton explains what that looks like in practice: https://www.inkbridgenetworks.com/blog/blog-10/aaa-information-security-184

Network scaling isn't just about adding more servers. It's a complex interplay of understanding traffic patterns, anticipating future needs, considering the human factor, and implementing intelligent design. In our experience, a well-designed network with 100 servers can outperform a poorly designed one with 1000. The art of scaling lies in balancing technical know-how with strategic foresight.

A medical device company deploys hundreds of thousands of health monitors with cellular connectivity. Blood pressure cuffs. Glucose meters. Each device gets an IP address via DHCP and transmits patient data through carrier networks.

When the mobile carrier needs to identify which customer account is associated with a specific device for billing or support, they need that information immediately.

The traditional approach: Build a custom REST API with authentication, documentation, client libraries, and ongoing maintenance. Integration takes weeks or months.

What this ISP did instead: Export DHCP lease data via standard DNS queries.
The mobile carrier queries the DNS server: "Who has 203.0.113.42?" The response comes back instantly: Customer identifier, device information.

There’s no need for custom API development or authentication infrastructure. Just standard DNS queries that every system already understands. Integration took minutes.

This is how ISPs are solving real operational challenges today.

Our new technical paper explains how DNS queries simplify DHCP lease data export for compliance, carrier integration, and network monitoring, without the complexity of custom APIs.

The xz utils backdoor took years of patient social engineering to execute.

The RubyGems takeover took a few clicks by someone with the right organisational access.

Different attacks, same root cause: processes that were opaque, undocumented, and untested.

Your RADIUS server should have its own hardware. Full stop.

We've seen this play out in customer deployments more than once: a RADIUS server sharing a host with a file server, running quietly at 99% idle - until someone kicks off a large download. Suddenly 100 GB of file transfer is starving the RADIUS server of CPU, network IO, and disk IO. Users start failing to authenticate. The network starts falling over.

The culprit isn't the RADIUS server. It's the shared hardware.

Even on a VM, even as a small ISP, dedicated hardware for your RADIUS server removes an entire category of failure. Other workloads can't steal your resources. Behaviour is predictable. Troubleshooting is simpler.

It's one of the most straightforward things you can do to make your network more reliable - and one of the most commonly skipped.

As a side event to TNC 2026 last week, we hosted a technical workshop bringing together some of the people who are actively shaping RADIUS standards - discussing what's changing, what's improving, and how those changes land for operators in the real world.

This is the kind of work that doesn't make headlines, but it's where the next generation of RADIUS standards actually gets made.

Left to right: Karri Huhtanen (Radiator Software), Fabian Mauchle (Switch), Alan DeKok (InkBridge Networks), and Paul Dekkers (SURFnet).

Good conversations with people who know what they're talking about.

Several of our largest global operator customers have signed on to the Open Telco AI Initiative announced at MWC 2026 - an effort to build AI models specifically trained on telecom data rather than relying on general-purpose hyperscaler platforms.

Jana Sedivy explains why this matters and what ISPs should be watching.
