What is an ISO 8583 Parser?

An ISO 8583 parser is a software tool used by payment processors and banks to decode the standard bit-mapped message format used for financial transaction card originated messages. IsoFluent automates this by converting raw hex data into human-readable narratives.

How does IsoFluent ensure data privacy?

IsoFluent utilizes a 'Zero-Data Retention' architecture. It runs as a private Docker container within your own Virtual Private Cloud (VPC). No PII, PAN data, or transaction logs are ever sent to external servers or cloud AI providers.

Can IsoFluent parse custom private fields?

Yes. Unlike rigid regex parsers, IsoFluent's local intelligence engine can identify and decode proprietary sub-fields within data elements like Field 55 (EMV Data) and Field 127 based on your specific implementation specs.

Does this work with Visa and Mastercard logs?

Yes. IsoFluent supports major schemes including Visa Base I, Mastercard IPM, and generic ISO 8583-1987/1993 standards.

The "Iron Gate" Architecture

Deterministic Parsing

We don't ask AI to guess fields. We use a strict Python parser rooted in your specific PDF specs to ensure 100% extraction accuracy.

🧠

Local Intelligence

Data is fed into a fine-tuned Local LLM (Llama 3) to generate the narrative. It explains the "Why" without hallucinating the "What".

🔒

Private Container

Your logs never leave your VPC. IsoFluent runs as a Docker container on your own infrastructure (AWS/GCP/Azure).

Evolution of Parsing

Why leading fintechs are moving away from Regex.

Comparison of Standard Regex Parsers vs IsoFluent AI
Feature	Legacy Regex Parsers	IsoFluent Engine
Field 55 (EMV) Decoding	✗ Fails on proprietary tags. Requires manual hex mapping.	✓ Auto-discovery. Identifies and labels non-standard TLV tags instantly.
Error Context	✗ "Invalid Length" (Generic exception).	✓ Narrative. "Field 39 mismatch: Length was 3, expected 2 per Visa Spec."
Data Privacy	⚠ Often Cloud SaaS (Data leaves VPC).	✓ 100% Local. Docker container runs in your secure enclave.
Setup Time	~ 4-6 Weeks (Writing custom parsers).	~ 15 Minutes (Pull Docker Image).

>> Supported Protocols & Fields
