Outcomes, in production.

Selected engagements, fully anonymised. Real systems we designed, secured, and put into production — and the measured results they delivered.

Banking · Compliance

−80%

hallucination rate

RAGEvaluationEU AI Act

A regulated-finance copilot the risk committee could approve.

Problem
A compliance team relied on a general-purpose LLM copilot that produced confident but unreliable answers, blocking it from production use under model-risk policy.
Solution
We built a retrieval-augmented architecture grounded in the bank's proprietary regulatory corpora, with a continuous evaluation harness measuring accuracy against a ground-truth set.
Impact
Hallucination rate cut by over 80% versus the baseline model. The system passed internal AI governance and went live for first-line compliance teams.

faster triage

Agentic AIHuman-in-the-loopObservability

Autonomous claims triage, with humans on the high-stakes calls.

Problem
Manual claims triage was slow and inconsistent, with senior adjusters spending most of their time on routing rather than judgement.
Solution
We deployed autonomous agents to handle high-volume routing autonomously, with human-in-the-loop checkpoints on every high-consequence decision, fully logged and reversible.
Impact
Triage throughput increased roughly tenfold on routine cases, with consistent decisioning and adjusters refocused on complex claims.

external surface mapped

EASMNIS2Continuous monitoring

Exposed assets discovered before attackers reached them.

Problem
A multi-site industrial group had no continuous visibility on what it exposed to the internet — domains, services, and forgotten assets accumulated across acquisitions.
Solution
We deployed continuous external attack-surface management (EASM), mapping every internet-facing asset and scoring exposure against known threat patterns.
Impact
The full external surface was mapped and critical exposures were prioritised and remediated, with continuous monitoring tied to NIS2 readiness.

Continuous

vendor scoring

Third-Party RiskEASMDORA

Vendor risk scored continuously, not once a year.

Problem
Third-party security was assessed through static, point-in-time questionnaires that were stale the moment they were filed.
Solution
We instrumented continuous scoring of each vendor's real, internet-facing attack surface, surfacing new exposures as they appeared rather than at the next review.
Impact
Vendor onboarding accelerated and aggregate third-party exposure fell, with a single live view for the risk function.
