Built by People Who
Understand Legacy

COBOL Bridge was born from decades of enterprise experience in defence, aerospace, and critical infrastructure. We didn't just study the problem of legacy modernisation — we lived it.

From Defence Aerospace to AI Governance

The journey from securing fighter jet systems to securing the world's COBOL infrastructure.

Where It All Began

James Castle spent decades leading Terranova Aerospace & Defence Group, overseeing mission-critical systems where failure was never an option. In that world, legacy code isn't a burden — it's the backbone of national security.

When he founded the Certified Safe AI Association (CSGA), the mission was clear: bring that same rigour to AI governance. The CASA certification framework was built on the principle that organisations deploying AI deserve the same safety assurance standards as those flying fighter jets.

Meanwhile, Nicholas Templeman was pioneering cognitive symbiosis research at the CSGA AI Research Institute — studying how humans and AI systems can work together more effectively. When Anthropic released the Model Context Protocol, both saw the same opportunity: a way to modernise COBOL safely, with built-in governance from day one.

COBOL Bridge was the result.

Why COBOL? Why Now?

Every day, 220 billion lines of COBOL process $3 trillion in global transactions. Banks, governments, healthcare systems, and defence agencies all depend on code written decades ago.

The developers who built these systems are retiring. AI can help — but only if it's governed properly. Ungoverned AI touching mission-critical COBOL is a risk no enterprise can afford.

We built COBOL Bridge to solve this exact problem: MCP-native tools with CASA certification baked in. Not governance bolted on after the fact, but AI safety assurance from the ground up.

What We Believe
"Legacy systems deserve modern governance. Every enterprise running COBOL has earned the right to modernise safely — with AI that's certified, transparent, and accountable."
— James Castle, Founder & Global Chairperson, CSGA

The CSGA Ecosystem

COBOL Bridge is part of a broader ecosystem of AI governance tools, certifications, and enterprise services.

CASA

Certified AI Safety Assurance

Four certification levels (CA-10 to CA-40) providing verifiable AI governance from basic awareness to defence-grade assurance.

25+

Enterprise Sectors

Purpose-built MCP governance tools for banking, healthcare, government, defence, insurance, telecommunications, and more.

70+

MCP Servers

The largest MCP governance tool catalogue in the industry, all built on Anthropic's Model Context Protocol standard.

What Guides Us

Safety First, Always

Every tool we ship is CASA-certified. We don't believe in governance as an afterthought — it's the foundation everything else is built on.

Open Standards

We build on MCP because open protocols create better outcomes. No vendor lock-in, no proprietary formats. Your data and workflows remain yours.

Enterprise Speed

Legacy modernisation shouldn't take years. Our tools deploy in hours, not months, without compromising on security or compliance.

Human-AI Partnership

AI augments human expertise — it doesn't replace it. Our cognitive symbiosis research ensures COBOL specialists remain at the centre of every modernisation decision.
