ESL FixCreator — Isolated Local LLM for Secure Code Fixes

Isolated, Local LLM System for Secure Software Code Fixes

ESL FixCreator uses local AI models on an isolated network to analyze C/C++/C# static analysis violations and propose safe, single-line fixes. No internet. No cloud. No data leaves your machine.

How It Works — Inside Your Secured Network

A complete, closed-loop workflow that never touches the outside world.

ESL FixCreator workflow
1

Scan C/C++ Projects

Parasoft Static Code Analysis Reports identify violations across your codebase.

2

Review & Send Fix Requests

ESL FixCreator presents violations and lets you select which to fix — individually or in batch.

3

Generate Fixes

A local LLM (via LM Studio) generates precise, single-line fixes without any network access.

4

Verify Fixes

Parasoft C/C++ TEST re-scans to confirm violations are resolved. Full audit trail maintained.

Core Capabilities

Intelligent code fixing that keeps your source code completely isolated.

AI-Powered Analysis

Local LLMs analyze violations in context — understanding your coding standards, compiler, and architecture to propose the perfect fix.

  • Context-aware suggestions
  • CERT, MISRA, CWE standards
  • Compiler-specific fixes

Precise Single-Line Fixes

Unlike tools that rewrite entire functions, FixCreator proposes one precise line change per violation — easy to review and safe to apply.

  • One violation, one line
  • Side-by-side diff preview
  • Predictable changes

Air-Gapped Security

Runs entirely on an isolated, local network. Your proprietary source code never leaves your secured environment — zero external connectivity required.

  • No internet required
  • Isolated local LLM
  • Sanitization server

Why ESL FixCreator?

Purpose-built for environments where security is non-negotiable.

100% Air-Gapped

Complete isolation from external networks. No data exfiltration risk — ever.

Secured Network Only

All processing stays within your organization’s secured, isolated local network.

Local LLM (LM Studio)

AI models run locally via LM Studio — no cloud APIs, no third-party services.

Sanitization Server

Built-in sanitization layer ensures code integrity before and after AI processing.

Multi-Standard Support

CERT-C, CERT-C++, MISRA-C:2012, CWE Top 25, and compiler-specific warnings.

Eclipse CDT Plugin

Native Eclipse integration with views, menus, diff viewer, and inline markers.

Also Available as an Eclipse CDT Plugin

All the power of ESL FixCreator, integrated natively into your Eclipse IDE — fix violations without leaving your editor.

Native IDE Integration

A thin Java plugin adds dedicated views, menus, preferences, inline markers, and a side-by-side diff viewer directly inside Eclipse CDT.

  • Violations view & commands
  • Compare/diff editor
  • Inline problem markers

Same Air-Gapped Engine

The plugin drives the same local Python engine over JSON-RPC — report parsing, guardrails, and LLM fixes all stay on your isolated network via LM Studio.

  • Local LLM, no cloud
  • Guardrails preserved
  • Zero data exfiltration

Full Feature Parity

Load Parasoft reports, fix single or batch violations with diff review, verify builds, and generate manual-fix HTML reports — all without leaving the IDE.

  • XML, SARIF, HTML, JSON reports
  • Single & batch fixing
  • Build verification
