Network resilience is now a board responsibility. We can help you evidence it.
Energy, water, transport, finance, health and digital infrastructure now face legal duties to manage the risks to the networks they depend on, and management is accountable. We help essential and important entities find their weak points, fix them, and prove it.
Gap analysis
Your network and suppliers measured against NIS2, DORA, CyFun or Cyber Essentials.
Resilience review
Single points of failure, hidden dependencies, routing and DNS hygiene.
Tabletop exercises
Incident-response scenarios run with your team, and written up as evidence.
Certification & board reporting
Support through ISO 27001, CyFun or Cyber Essentials, and findings your audit committee can act on.
Selected work
Infrastructure people rely on, whether they know it or not.
The people behind your network
Senior people on every network we run.
When you call us, you talk to the engineers who design and run your network, not an account manager. And we share what we know: more than 230 talks since 2005, at RIPE, IETF, Euro-IX, UKNOF, APRICOT, AfPIF and the Global Peering Forum.

Talk to an engineer
Most of our work starts over a coffee.
Bring us the network problem, the stalled project or the audit finding. We’ll tell you what we’d do about it, and whether we’re the right people to help. The first conversation costs you nothing but an hour.
In Dublin? Let's meet for a coffee.
Otherwise, we’ll do it on a call.
