Banks and insurers are moving forty years of COBOL into modern cloud and AI systems. IronParse is the independent layer that verifies every field survived the move — and signs a receipt your auditors and your AI both trust.
Flip a copybook to JSON with a script and the damage is invisible — until a regulator, a miscalculated premium, or an underpaid claim finds it for you. And if you feed that silently-corrupted data into a new AI system, it now hallucinates on bad data at scale, with no way to prove what broke.
PIC S9(7)V99 COMP-3 — a packed-decimal premium becomes a string.
OCCURS 12 TIMES — a twelve-element coverage array collapses to one.
REDEFINES — a union silently reads the wrong field.
The buildout of new AI and cloud data centers runs on enterprise data still trapped in COBOL. Moving it without proof of fidelity means betting your models, your compliance, and your books on a migration nobody verified. IronParse removes the bet.
IronParse reads your record layout structurally — no model guessing at field names — emits a typed schema, runs five deterministic gates, and produces a signed parity receipt. The same input always yields the same output, byte for byte. It runs entirely inside your perimeter; we never see your data.
Your record layout, exactly as the mainframe defines it — every clause load-bearing. Packed decimals, REDEFINES unions, and variable OCCURS arrays each carry meaning a naive migration drops.
01 POLICY-RECORD. 05 POLICY-NO PIC X(10). 05 PREMIUM-AMT PIC S9(7)V99 COMP-3. 05 CVG-CNT PIC 9(2). 05 COVERAGE OCCURS 1 TO 12 DEPENDING ON CVG-CNT. 10 PLAN-CODE PIC X(2). 10 LIMIT-AMT PIC S9(9) COMP-3. 05 RAW-DATES REDEFINES COVERAGE PIC X(132).
The parser walks the level hierarchy (01 → 05 → 10) and decodes each clause precisely. No model in the loop, nothing to hallucinate — the same tree on every run.
PIC S9(7)V99 COMP-3 → number (packed BCD, 2 dp) PIC X(10) → string (length 10) REDEFINES → union (overlaid view) OCCURS … DEPENDING → array (len = CVG-CNT)
The parsed tree is emitted as real, executable schema — Zod, field for field. Code your team can read, version, and run in CI: the contract between the legacy record and the modern API.
z.object({
policyNo: z.string().length(10),
premiumAmt: z.number(),
cvgCnt: z.number().int(),
coverage: z.array(CoverageSchema),
})
Five deterministic gates run over the result. All must pass — no partial credit. A field is only counted as preserved once it clears every one.
The payoff: a signed artifact your security team and your auditor both trust — input and output hashes, field counts, and gate verdicts in one place. We never see your data; the engine runs inside your perimeter.
Every claim on this page is backed by a real engine running at the edge. Generate a parity receipt against a sample ACORD record right now — or read the machine-readable JSON your systems would consume.
Scoped to one policy-admin system or copybook set, delivered with a full parity report. The pilot ends with a receipt that proves the migration lost nothing — the artifact your risk team and your auditors can stand behind.
