AI is rapidly changing how London businesses work. From professional services firms in the City to creative agencies in Fitzrovia, organisations are using AI to write and summarise content, analyse information, automate processes and improve productivity.
But adopting AI securely requires more than giving employees access to a new tool. It requires clear policies, approved platforms, appropriate access controls, user awareness and ongoing oversight.
AI security was one of the themes raised in conversations at our recent stand with IASME at the International Cyber Expo 2026 at Olympia London. Alongside discussions about Cyber Essentials and managed cybersecurity, we were hearing increasing interest in how businesses can adopt new technologies without creating new risks.
So to mark National Cyber Security Month, we’re taking a closer look at how London businesses can make the most of AI while protecting their data, customers and reputation.
One of the biggest challenges for businesses is that AI adoption may already be happening outside the IT team's view.
Employees can easily turn to free consumer AI tools to draft emails, summarise documents, analyse spreadsheets or help write code. The risk comes when sensitive business information, customer details or confidential documents are entered into platforms that have not been approved by the organisation.
This is known as shadow AI, and it is becoming an important cybersecurity consideration for businesses.
You can read more about the risks in our guide to shadow AI and the new cybersecurity risk facing London businesses.
The answer is not necessarily to ban AI altogether. A more effective approach is to establish clear rules around its use. An AI Acceptable Use Policy can explain which tools are approved, what information must never be entered into AI systems and when human review is required.
Once an organisation understands how employees are using AI, the next step is to provide secure alternatives.
Enterprise platforms such as Microsoft 365 Copilot and AI services within Azure can provide businesses with greater control over data, identity, access and governance than unmanaged consumer tools.
However, choosing an enterprise AI platform is only part of the solution.
AI can only work within the permissions and information available to it. If an employee should not have access to confidential board papers, financial information or sensitive client records, those permissions need to be correct before AI is introduced.
This makes identity management, SharePoint permissions, Microsoft 365 security and data governance increasingly important parts of an AI strategy.
AI adoption can also introduce new data protection and cybersecurity considerations.
Where AI is being used with personal or sensitive information, organisations should understand what data is being processed, where it is stored, who can access it and which third parties or sub-processors may be involved.
For higher-risk processing, a Data Protection Impact Assessment may be appropriate, alongside consideration of UK GDPR and relevant ICO guidance.
There are cybersecurity risks to consider too. AI systems can introduce or amplify threats such as prompt injection, excessive permissions, insecure integrations and data leakage. Existing security controls therefore need to evolve alongside AI adoption.
Cyber Essentials and other established security frameworks can provide useful foundations, but businesses should also consider how their specific AI applications interact with their wider IT environment.
For organisations exploring Microsoft Copilot and wider AI adoption, the practical starting point is understanding whether your existing IT environment is ready.
That can include AI readiness assessments, Microsoft 365 security and governance reviews, data and permissions audits, role-specific Copilot training, hands-on workshops and guidance on AI governance and security best practice.
As a Microsoft Solutions Partner for Data & AI, alongside our 5 other Microsoft specialisms, Fitzrovia IT can help businesses consider both the opportunities and the security implications of introducing AI.
The future of AI in business is not simply about what the technology can do. It is about how responsibly and securely organisations choose to use it.
For London businesses, that means putting governance, security and human oversight in place from the start.
