What sets it apart
The mainframe never runs alone
A business action rarely stays on the mainframe. It starts in a portal, crosses an integration layer, runs a COBOL routine, touches packaged software, and returns. Mainframe-only tools see one slice of that. rhino reads the mainframe and everything connected to it, across every tech stack, as one governed picture.
The mainframe core
COBOL on CICS, VSAM and DB2 data, batch and JCL, read natively at the source.
Everything around it
Custom code, packaged software, low-code, integration fabric, and green-screen access, read in the same graph.
The seams, mapped
rhino traces a single business action end to end, so the risk that lives where these layers meet becomes visible.
This is the difference from mainframe-only modernization. rhino is the logic layer that reads across estates, not a point tool bounded by the mainframe.
The hardest part of the estate
The logic nobody can read, running what matters most
The mainframe runs the business. The rules on it are decades old, were never documented, and the people who wrote them have retired. So everyone is afraid to touch it, and nothing modern, cloud or AI, can safely be built on top.
Decades of undocumented logic
Business rules embedded across COBOL, JCL, and data over thirty or forty years, with no source of truth for what they do.
The knowledge has left
The people who understood the system have retired. What remains is code no one alive fully understands.
Nothing can build on it
You cannot modernize, and you cannot ground an AI agent, on logic you cannot read. The core stays frozen.
How it works
Extract. Structure. Govern. On the mainframe.
rhino reads COBOL and mainframe languages natively, with no intermediate dependency, and turns what the mainframe actually does into a governed system of record. The real rules, taken from the source, with full lineage.
01
Extract
Read COBOL and mainframe logic natively from the source, across programs, batch jobs, and data, with no black box and no reconstruction from memory.
02
Structure
Organize it into Universal Application Notation, a version-controlled logic graph with full lineage back to the source.
03
Govern
Hold it as the system of record, then feed it to migrations and ground AI agents, so they act on the real rules.
The path
From COBOL to a running service, in weeks
The same path we run in every demo, on the hardest stack there is.
01
Discovery Sprint
Point rhino at the mainframe estate.
02
Governed ontology
The logic, structured and traceable.
03
Implementation spec
Machine-readable, agent-ready.
04
rhino agent harness
With the AI IDE of your choice, forward-engineer the replacement.
05
Running service
Modern, on the cloud you trust.
Who it's for
Built for both sides of the mainframe problem
