Many organisations have software that works but they don't know how it will hold up as they grow. A legacy code analysis replaces guesswork with facts.
We inspect source code, architecture and infrastructure for real risks. These include security gaps, outdated dependencies and maintainability bottlenecks.
You get a prioritised action plan, not a generic checklist. It separates stable areas, urgent work and valuable modernisation opportunities.
Refactor, partly rebuild or migrate to a new stack – the analysis gives you the evidence to decide.

Whether to refactor, partially rebuild or start fresh – we tell you what makes economic sense
A legacy code analysis is the essential first step before investing in modernisation.
We assess code quality, technical debt and security risks across your existing software. The evidence supports informed investment decisions.
The review covers architecture, dependencies, test coverage and compliance. Its roadmap prioritises actions and estimates the required effort.
Technical debt accumulates silently. What starts as a shortcut during a sprint becomes an architectural constraint that affects every future change.
Our analysis quantifies that debt so you can budget for it and address it strategically rather than reactively.
We have assessed Delphi, Java, .NET, PHP, Python and JavaScript codebases. They range from desktop monoliths to distributed microservices.
Every analysis ends with a stakeholder presentation. We explain risk exposure, modernisation effort and expected returns in clear business terms.
This ensures both technical teams and decision-makers have a shared understanding of the path forward.
The analysis is the entry point to our broader legacy modernisation programme. The report remains useful if you implement with us or brief another vendor, and it supports targeted module replacement without obliging you to continue with us.

It is not a complete security, compliance or enterprise-architecture audit.
It covers the agreed codebase, build, core dependencies and selected risk hotspots; additional scope is estimated separately.
We review code quality, architecture, performance and security.
Every finding documents severity, impact and estimated effort. You also receive a prioritised modernisation roadmap.
The standard five-day package covers the agreed repository and risk questions from kick-off to presentation.
Day one covers access, while days two to four cover analysis. On day five, we present the risk report. A larger codebase can require two to four weeks. We estimate that duration after an initial scoping call.
We offer a fixed price; there are no hidden costs.
The exact price is agreed in an initial call.
You receive a detailed report and a prioritised roadmap.
We present every finding to your team. We can support later modernisation, but there is no obligation. Many clients use the report to brief internal teams or other vendors.
No.
We work with your source repository and build configuration. When relevant, we request anonymised database schemas or API documentation. We never require live-system or customer-data access.

A legacy code analysis turns assumptions into evidence about dependencies, security, testability and operational risk. It supports due diligence as well as a practical modernisation roadmap.
The output prioritises actions by business impact so teams can stabilise first and replace only where the evidence supports it.
