Artificial Intelligence is rapidly moving from experimentation to operational reality. Organisations across the UK and Ireland are deploying AI-powered assistants, automating business processes, enhancing customer engagement and improving decision-making. However, as AI adoption accelerates, so too do the cyber security, governance and compliance risks associated with it.
That is why the recent publication of two new guidance documents by Ireland’s National Cyber Security Centre (NCSC) deserves significant attention, not just from public sector organisations, but from every business considering the use of AI.
The NCSC has published:
- NCSC AI Cyber Security Risk Assessment: Public Sector Deployment
- Securing AI Adoption in the Public Sector: Cyber Security Guidelines for AI Deployments
The NCSC states that while these resources are designed for public sector bodies, the principles and measures they contain are applicable to organisations of all types and sizes.
At NexGen Cyber, we strongly welcome this guidance and view it as an important milestone in helping organisations deploy AI securely, responsibly and with confidence.
AI Is Not Just Another Technology Risk
Many organisations are approaching AI implementation in the same way they would adopt a new software application or cloud service.
The NCSC rightly highlights that AI fundamentally changes an organisation’s risk profile. AI expands the attack surface, increases the movement of data between systems, introduces new supply chain dependencies, and creates risks that can evolve over time as models are updated and interact with new data.
This means security cannot simply be bolted on after deployment.
Instead, security must be considered throughout the entire AI lifecycle:
- Design
- Development
- Deployment
- Maintenance
- End-of-Life
This lifecycle approach is a central theme of the NCSC guidance and aligns closely with the security-by-design principles that NexGen Cyber advocates across all digital transformation programmes.
The Risk Assessment Every Organisation Should Read
The NCSC AI Risk Assessment highlights several critical areas organisations must consider before deploying AI solutions.
Key assets at risk include:
- Sensitive organisational data
- Citizen and customer information
- Identity and access management systems
- Security infrastructure
- AI models and agents
- Third-party suppliers and AI providers
- Business processes and operational services
The report also highlights the growing concern around Agentic AI systems, AI tools capable of taking actions autonomously using elevated permissions and credentials. These emerging technologies present significant opportunities but also introduce entirely new categories of cyber risk.
For many organisations, this will be a new concept.
Questions businesses should now be asking include:
- What data is our AI solution accessing?
- Where is that data being processed?
- Can the AI make decisions or actions on our behalf?
- What happens if the AI is manipulated or compromised?
- Do we understand our AI supply chain?
These are governance questions as much as they are technical questions.
Practical Guidance Rather Than Fear
One of the most positive aspects of the NCSC publications is their balanced approach.
The guidance does not seek to slow innovation or discourage AI adoption.
Instead, it recognises that AI has the potential to significantly improve operational efficiency, service delivery and decision-making. The objective is to ensure that organisations realise these benefits safely and securely.
This mirrors the approach we take at NexGen Cyber.
The conversation around AI should not be:
“Should we use AI?”
Rather, it should be:
“How can we use AI securely and responsibly?”
Seven Principles That Every Business Can Apply
The NCSC Secure AI Adoption guidance introduces seven practical principles that organisations can apply throughout the AI lifecycle.
These principles focus on:
- Building trust through informed design and risk awareness
- Identifying and securing assets throughout the AI lifecycle
- Building resilience through effective security controls and supply chain assurance
- Implementing rigorous testing and validation
- Ensuring accountability, explainability and transparency
- Maintaining continuous oversight and rapid response capabilities
- Safely retiring AI systems and associated assets
Although written for public bodies, these principles align closely with established cyber security frameworks such as:
- ISO 27001
- NIST Cyber Security Framework
- NIS2
- Cyber Fundamentals (CyFun)
- GDPR
- EU AI Act
In practice, they represent a strong blueprint for secure AI governance regardless of industry sector.
What This Means for UK & Irish Businesses
Whether you are a law firm, healthcare provider, manufacturer, charity, financial services organisation or SME, the message is clear:
AI adoption requires governance.
Many businesses are already using tools such as Microsoft Copilot, ChatGPT, Claude, Gemini and industry-specific AI solutions without fully understanding the associated risks.
Common challenges we see include:
- Lack of AI usage policies
- Uncontrolled sharing of sensitive data
- Limited visibility of AI tools being used by employees
- Weak supplier assurance processes
- No AI-specific risk assessment framework
- Poor understanding of emerging regulatory requirements
The NCSC guidance provides an excellent starting point for addressing these challenges and building an AI programme that is secure, compliant and sustainable.
NexGen Cyber’s Perspective
As organisations accelerate AI adoption, cyber security must remain a business enabler rather than a barrier.
The NCSC has provided Ireland with a practical, risk-based framework that encourages innovation while ensuring security remains at the forefront. We believe these publications will become foundational references for AI governance across Ireland over the coming years.
At NexGen Cyber, we are helping organisations:
- Assess AI-related cyber risks
- Develop AI governance frameworks
- Implement secure deployment controls
- Evaluate AI suppliers and third parties
- Align with NIS2, ISO 27001, GDPR and emerging AI regulations
- Build AI security awareness across leadership and operational teams
The organisations that succeed with AI will not simply be the fastest adopters, they will be the ones that adopt it securely, responsibly and with confidence.
Final Thoughts
The NCSC’s latest publications arrive at a critical moment for both the public and private sectors. AI offers transformative opportunities, but without effective governance and cyber security controls, those opportunities can quickly become risks.
We encourage every business leader, board member, IT manager and cyber security professional to review these documents and consider how the principles can be applied within their own organisation.
Secure AI adoption is not just a public sector challenge.
It is now a business imperative.
