We connect the systems enterprises already run. That same layer decides whether your AI agents can do anything useful — and it is on the front line when cryptographically relevant quantum computing arrives.
Three horizons, one spine
Three horizons, one spine
Integration work has always been about what happens between systems. Agents and post-quantum cryptography are not new departments — they are new demands on that same middle.
The argument
Nobody sets out to build the version on the left. It arrives one urgent project at a time, each one reasonable in isolation. The cost is not the building — it is that every future change now has fifteen places to break.
The same arithmetic decides whether an agent estate stays governable, and how many places you have to migrate when the cryptography changes.
Services
Ten services across three practices. Most engagements start with one and widen once the interface inventory shows what else is in the way.
Make the systems you already own talk to each other — across application, company and hosting boundaries.
Design, publish, govern and retire APIs on a lifecycle you can audit — create, control, consume.
Treat integration artefacts like software: versioned, tested, promoted through environments, shipped by a pipeline.
Get off ageing middleware without a big-bang rewrite — assess, sequence, migrate, decommission.
Expose enterprise systems to agents as governed tools — scoped, permissioned and logged — instead of pasting credentials into a prompt.
Put agents inside real business processes, with the human checkpoints and rollback paths that make them shippable.
Use models where they genuinely compress integration work — mapping, migration and documentation — and nowhere else.
Find out where cryptography actually lives in your integration estate — because almost nobody has that list.
Sequence the move to NIST's post-quantum standards across interfaces you don't fully control.
Rebuild the integration layer so the next algorithm change is a deployment, not another multi-year programme.
Add integration and AI engineers to your existing teams without carrying sourcing, recruiting and retention overhead.
Approach
The same four steps whether the driver is a middleware migration, an agent programme or a cryptographic one. The order matters more than the technology.
Interface inventory, current-state architecture, and the dependencies nobody documented. The list of what talks to what is usually the first real deliverable — and for quantum work, the cryptographic inventory that sits on top of it.
A to-be architecture and a migration order: which interfaces move first, what runs in parallel, where the cutover risk sits, and what has to wait on a third party you don't control.
Flows and agent tools in source control, built and deployed by pipeline, promoted through environments. Reviewable, repeatable and reversible — including the parts a model wrote.
Monitoring, alerting, evaluations and runbooks your team owns — so neither the integration layer nor the agent estate becomes a black box only we can touch.
Platforms
No reseller agenda and no preferred-vendor tax. If the right answer is the tool already in your estate, that's the recommendation.
Deepest on IBM webMethods — Integration Server, Trading Networks, Universal Messaging and the EDI module, across builds, version migrations and 24×7 production support — and on MuleSoft. Familiar with the rest, and honest about the difference.
