Shadow AI, which is the unauthorised use of AI tools by employees, is rapidly increasing as accessibility and adoption grow. It creates significant risks to data security and UK GDPR compliance by enabling unmonitored data sharing, loss of control, and a lack of audit trails. Effective mitigation requires visibility, governance policies, technical controls, approved alternatives, and employee training. Connect with Redpalm’s team to manage shadow AI risks.
Growing AI Usage
From summarising research articles to creating images and videos for social media marketing, UK businesses are rapidly adopting AI tools to streamline various tasks. A 2025 survey by Sapio Research found that 86% employees used AI tools weekly, with 60% agreeing to use unsanctioned AI tools even if they presented security risks. While AI has made its way into daily operational workflows, helping teams innovate and generate new ideas, it also carries an often invisible risk in the form of shadow AI.
Like shadow IT, shadow AI is when your organisation’s employees use AI tools without prior consent or approval. In 2026, the difference lies in its scale and impact. AI tools are more powerful, more accessible and more deeply integrated into business processes than ever before. This presents a serious challenge, especially if your organisation is subject to GDPR.
In this guide, we explore the growing risks of shadow AI on your data and GDPR compliance, and the steps you can take to regain control of your organisation’s AI usage.
What Is Shadow AI And Why Is It Growing Rapidly?
Shadow AI refers to the use of artificial intelligence tools, platforms, or features without the knowledge or approval of IT, security, or compliance teams. This includes everything from pasting sensitive information in public chatbots to using unauthorised AI-powered SaaS tools to automate tasks.
What Is Driving the Growth of Shadow AI?
Easy Accessibility
With many AI tools free or at a low cost, all you need is an email address to get started. Employees under pressure to improve productivity often turn to these tools without considering the hidden risks shadow AI presents.
Expectation Gaps
A growing gap between employee expectations and organisational readiness. While your teams are ready to adopt AI to work faster and smarter, you may still be considering how to implement approved, secure AI solutions. This creates a gap that shadow AI fills.
AI in Existing Platforms
Your existing platforms may already have AI embedded, including your email systems and CRMs. This makes it difficult to distinguish between authorised and unauthorised usage.
These key reasons make shadow AI an operational risk rather than a fringe problem.
How Shadow AI Creates Hidden Data Risks
The risks posed by shadow AI use are invisible, making it especially dangerous. Because it operates outside authorised and vetted systems, your organisation is in the dark about how data is being used, stored and shared.
Consider a scenario where a UK financial services firm is racing to prepare client reports for a quarterly review. Short on time, a team member decides to use a public AI chatbot to speed things up. They paste sections of a report containing client names and contact information, investment portfolio and financial performance, and notes of risk profiles and future recommendations into the public AI chatbot tool.
What may seem like a harmless action to work more efficiently, in reality, triggers three critical risks.
1. Unauthorised Data Sharing
Personal and financial data has been shared with a third-party AI platform with which the organisation has no agreement and has no Data Processing Agreement in place. This makes the data transfer unlawful under UK GDPR.
2. Loss of Data Control
The firm has no visibility into where the data is stored, how long it’s retained, or whether it’s being used to train AI models. The sensitive data has left the company’s secure environment.
3. Potential Data Breach
If the AI platform suffers a data breach or reuses data in its outputs to other users, it could expose sensitive financial information.
4. No Audit Trail
Because they used an unauthorised tool, there is no record of the interaction. If there’s an investigation, the firm can’t explain what happened to the data.
Without monitoring, logging, and governance, shadow AI creates a blind spot where businesses and their clients can’t see where their data is going or how it’s being used.
Why Shadow AI Puts GDPR Compliance At Risk
The UK GDPR requires your organisation to be accountable and transparent, and to follow data minimisation and security principles. But shadow AI directly challenges these.
– You risk a compliance breach by sharing data with third-party organisations without a legal basis or appropriate Data Processing Agreements.
– To be transparent, you need to inform data subjects of how their data is being used. But organisations are kept in the dark during shadow AI usage, which is a clear violation of GDPR obligations.
– With no clear record of how data has been processed by AI tools, there is no way to maintain an audit trail, introducing accountability issues.
– If sensitive information is entered in unsecured or unregulated platforms, the data can be exposed, lost, or misused. This can also lead to AI-related data breaches.
– You also risk high financial penalties of up to £17.5 million or 4% of global annual turnover, whichever is higher.
– You also risk reputational harm and undermine customer trust.
Regain Control Of AI Usage with Redpalm
Addressing shadow AI risks needs a well-planned strategy. The goal is to bring AI usage under control in a secure and compliant way, not eliminate its use completely.
– Visibility: You must first find out where and how AI tools are used without authorisation.
– Governance: Set clear AI governance policies with defined guidelines aligned and compliant with GDPR on which AI tools can be used, how they can be used, and what types of data can be shared.
– Technical controls: Implement solutions such as Data Loss Prevention (DLP), access controls, and AI monitoring tools to prevent sensitive data from being shared.
– Provide approved AI alternatives: Employees will more likely use compliant tools over shadow AI if their needs are met.
– Training: Invest in training and awareness to educate employees on the shadow AI threats posed by continued use and their responsibilities under GDPR.
– Partner with specialists: Partnering with experienced specialists like Redpalm can further support this process.
