Core Modernisation
De-risk core and legacy migration in a sandbox, not in production.
Test integrations, interfaces and migration approaches against representative synthetic data in an isolated environment, before you touch a single live system.

The problem
The estate is full of redundancy and tech debt, and nobody can safely experiment with it.
New leaders inherit sprawling estates and the inherited belief that modernisation must be slow and dangerous, because there is nowhere to try things. The real competitor is that status quo. An isolated environment with representative data lets teams prototype migration paths, test integrations and prove approaches with evidence, before the high-stakes production work begins.
What teams prove here
Every test runs in an air-gapped workspace, on representative data, with an evidence pack at the end.
Integration testing
Validate how new platforms talk to core interfaces against synthetic data, before any connection to live systems.
Migration prototyping
Prototype and compare migration approaches in a contained environment to surface risk early and cheaply.
AI-assisted modernisation
Use Claude, Cursor and AI tooling on air-gapped workspaces to accelerate analysis and refactoring of legacy code.
Evidence for change boards
Leave with documented proof that an approach works, the input change and risk governance actually want.
The data
Representative by default. Real only if you choose.
Synthetic datasets come pre-loaded, so evaluation starts on day one with zero exposure.
Synthetic core-banking & ledger data
Synthetic customer & account records
Representative interface & message samples
Straight answers
Q.
Does any of this run against our live core?
No. Everything runs in an isolated environment on representative synthetic data. You prove the approach first, then take a de-risked plan into production.
Q.
Can our teams use AI tooling here?
Yes. Air-gapped workspaces come with AI development tooling such as Claude and Cursor, so teams accelerate legacy analysis without exposing code outside the boundary.
Q.
What does the change board get?
Documented evidence that an integration or migration approach works on representative data, replacing assumption with proof.
