The Challenge Image

The Challenge

Critical infrastructure operators need realistic ways to evaluate cybersecurity weaknesses, test security scenarios, and support compliance requirements without disrupting the systems they rely on every day.

Testing directly against live production infrastructure introduces operational risk. At the same time, generic cyber ranges or manually modeled environments may not accurately reflect the complexity and conditions of real operational systems.

For organizations managing critical infrastructure, this creates a difficult balance between realistic cybersecurity assessment and operational continuity.

The Goal
To strengthen the cyber resilience of critical infrastructure through safer, more realistic, and AI-assisted cybersecurity assessment.

Empowering innovation through cutting-edge technologies

The technical stack supporting the project combines application development, identity management, data storage, and infrastructure technologies required to build and operate the LLM4CIP platform.

Solution Overview

LLM4CIP combines infrastructure replication, cybersecurity assessment, and AI-assisted capabilities into an integrated environment for critical infrastructure security testing.

Asset owners can provide a digital representation of their infrastructure for assessment without exposing live operational systems. Platform operators can manage multiple replicas and coordinate cybersecurity scenarios across isolated environments.

The solution supports repeatable assessment while maintaining clear separation between testing environments and production infrastructure.

Cyber Digital Twin Workflow

The Cyber Digital Twin follows a clear process that turns real infrastructure into a safe environment for cybersecurity assessment.

LLM4CIP Digital Twin Workflow Image

Capture

A lightweight agent captures the current state of the target infrastructure and the information required for accurate replication.

Reconstruct

The captured environment is recreated as an operational replica across supported infrastructure environments.

Isolate

The replica is kept strictly separated from production systems, allowing testing without affecting live operations.

Assess

Cybersecurity scenarios and NIS2-oriented assessments can then be executed against the replicated environment.

A Different Approach to Cybersecurity Testing

The LLM4CIP approach is designed to reflect real infrastructure as closely as possible while keeping assessment environments safe and isolated.

Cybersecurity Testing

Round check fill icon
Automated Infrastructure Capture

The platform captures the actual as-running state of the target environment instead of relying on manual infrastructure modelling.

Round check fill icon
Isolation by Design

Replica environments are isolated from production by design, enabling security testing without exposing live systems.

Round check fill icon
Physical & Virtual Infrastructure

The approach extends beyond cloud and virtual machines to support a broader range of real-world infrastructure environments.

Round check fill icon
Real Infrastructure, Not a Generic Testbed

Assessments run against a replica of the asset owner’s own environment rather than a generic or representative test setup.

LLM4CIP Development Status Image

Current Development Status

LLM4CIP is currently in the architecture and implementation phase.

During the first stage of development, the consortium defined the shared system architecture, technical integration points, and functional requirements that will guide implementation across the project.

Recent work has focused on three core technical challenges:

Round check fill icon
faithfully capturing an infrastructure environment.
Round check fill icon
reconstructing that environment quickly as a working replica;
Round check fill icon
maintaining strict isolation between replicas and production systems.

Frequently Asked Questions

1. Can you integrate AI into an existing software product?

Absolutely. Our team can assess your current system and recommend how artificial intelligence features, such as automation, recommendation engines, or predictive analytics, can be integrated effectively. Whether it's enhancing user experience or streamlining operations, we ensure AI is added where it delivers real value without disrupting your core functionality.

2. What types of AI projects has ASSIST Software delivered?

We’ve developed AI solutions across industries, from natural language processing in customer support platforms to computer vision in manufacturing and agriculture. Our expertise spans recommendation systems, intelligent automation, predictive analytics, and custom machine learning models tailored to specific business needs.

3. What is ASSIST Software's development process?  

The Software Development Life Cycle (SDLC) we employ defines the stages for a software project. Our SDLC phases include planning, requirement gathering, product design, development, testing, deployment, and maintenance.

4. What software development methodology does ASSIST Software use?  

ASSIST Software primarily leverages Agile principles for flexibility and adaptability. This means we break down projects into smaller, manageable sprints, allowing continuous feedback and iteration throughout the development cycle. We also incorporate elements from other methodologies to increase efficiency as needed. For example, we use Scrum for project roles and collaboration, and Kanban boards to see workflow and manage tasks. As per the Waterfall approach, we emphasize precise planning and documentation during the initial stages.

5. I'm considering a custom application. Should I focus on a desktop, mobile or web app?  

We can offer software consultancy services to determine the type of software you need based on your specific requirements. Please explore what type of app development would suit your custom build product.   

  • A web application runs on a web browser and is accessible from any device with an internet connection. (e.g., online store, social media platform)   
  • Mobile app developers design applications mainly for smartphones and tablets, such as games and productivity tools. However, they can be extended to other devices, such as smartwatches.    
  • Desktop applications are installed directly on a computer (e.g., photo editing software, word processors).   
  • Enterprise software manages complex business functions within an organization (e.g., Customer Relationship Management (CRM), Enterprise Resource Planning (ERP)).

6. My software product is complex. Are you familiar with the Scaled Agile methodology?

We have been in the software engineering industry for 30 years. During this time, we have worked on bespoke software that needed creative thinking, innovation, and customized solutions. 

Scaled Agile refers to frameworks and practices that help large organizations adopt Agile methodologies. Traditional Agile is designed for small, self-organizing teams. Scaled Agile addresses the challenges of implementing Agile across multiple teams working on complex projects.  

SAFe provides a structured approach for aligning teams, coordinating work, and delivering value at scale. It focuses on collaboration, communication, and continuous delivery for optimal custom software development services.
