API-first banking, FAPI-grade security, HMAC integrity and PCI-DSS-aligned delivery.
We design, build and manage the APIs, gateways and event streams that move your business — and we protect every one of them, from the gateway to the cryptographic key.
Most firms either connect systems or secure them. The seam between the two — where an open API becomes an attack surface, where a key becomes a liability — is exactly where breaches and outages live. We engineer both sides of that seam, together.
APIs, event streams and AI as first-class enterprise assets — designed, built, managed and governed.
Every connection — and every model — protected: identity, cryptography, assurance and governance.
From a single proxy to a production AI service to a national-grade security programme, each capability stands on its own and compounds with the others. Every engagement is delivered by senior engineers, documented in full, and handed over to you.
Platform selection, onboarding, migration and lifecycle for Apigee, Axway, Azure APIM, Gravitee and Kong — delivered with 100% automated CI/CD.

“Our gateway is a black box — every change risks breaking production.”
→We bring it under version control with automated CI/CD, robust fault handling and real observability, so changes are safe, traceable and fast.
“We're locked into a platform that's being sunset, with a hard migration deadline.”
→Zero-downtime, proxy-by-proxy re-platforming with production-replay parity testing — so consumers never feel the move.
“Our APIs are the front door and we don't know what's actually exposed.”
→Continuous discovery of shadow and zombie APIs, OWASP-aligned posture scoring, and runtime threat detection across APIs and event streams.
“We want to ship GenAI, but data leakage, hallucination and the EU AI Act scare us.”
→Pragmatic AI implementation with guardrails and LLM red-teaming, governed to the EU AI Act and ISO 42001 — value in production, safely.
“Our cryptography and HSM setup is fragile, and only one person understands it.”
→Hardened key lifecycle, documented HSM operations and PKI/mTLS done correctly — plus knowledge transfer so it's no longer a single point of failure.
“We can't hire senior architects and platform engineers fast enough.”
→We allocate proven specialists — embedded or as a factory — and design every engagement to leave the capability with your teams.
“Audit is coming and our security can't be evidenced.”
→Risk-led ISMS and ISO 27001 / 20000-1 / 9001 readiness, with the evidence framework to pass it and the cadence to sustain it.
“AI, APIs and security are three different vendors who don't talk to each other.”
→One engineering team across all three — so your AI agents, the APIs they call and the controls around them are designed and secured together.
Engage us for the thinking, the building, or the team. Most clients use all three over time, and the seam between them is where we're strongest: the architects who set direction also lead the build and stay accountable for it.
We assess your estate, threats and options, then hand you a costed, opinionated roadmap — reference architecture, target operating model and the decisions that de-risk what comes next. You get clarity before you spend.
Senior engineers build it — APIs, event streams, AI, security controls and the platforms that run them — with fixed-fee onboarding, 100% automated CI/CD and full handover, IP included. We own the outcome, not just the hours.
When you need the right people more than another report, we allocate best-in-class solution architects, platform engineers and security specialists — embedded in your teams or as a flexible delivery factory. Capability that scales up and hands back.

We map your integration estate, threat surface and platform constraints in a focused working session.
Reference architecture, conventions and a costed plan — co-designed in your templates and standards.
Platforms stood up with hardened defaults and 100% automated CI/CD, at a fixed fee.
APIs, event streams and security controls delivered inside your sprints, secured by design.
Documentation, pairing and full IP transfer — plus 24/7 monitoring & support if you want it.
We focus where a broken integration or an exposed API carries real cost — regulated, high-availability and critical-infrastructure sectors.
API-first banking, FAPI-grade security, HMAC integrity and PCI-DSS-aligned delivery.
OT/ICS security, SCADA hardening and critical-infrastructure resilience for the grid.
Critical Information Infrastructure protection, ISMS and national-grade assurance.
API management and event streaming that connect partners, fleets and platforms.
Secure integration of sensitive data with privacy and compliance built in.
Event-driven architectures linking commerce, supply chain and operations.
A 45-minute working session with our principal engineers. We'll review your integration estate, threat surface and platform options, and leave you with a costed next step.
