The data protection landscape is shifting faster than at any point in the past decade. Board-level decisions require current, verified data — not vendor marketing.
Every statistic in this report is sourced, verified, and formatted for direct inclusion in board presentations and security investment cases. No vendor bias, no inflated figures — just the data your leadership team needs to approve data protection budgets.
The report provides the first comprehensive analysis of generative AI data leakage at enterprise scale. Understand the actual volume, nature, and risk profile of data flowing to AI tools across your industry — essential intelligence for any organisation adopting AI.
EU AI Act, expanding GDPR enforcement, US state privacy laws — the regulatory landscape is more complex than ever. The report maps compliance obligations by sector and jurisdiction, helping legal and compliance teams prepare for 2026 enforcement actions.
The report includes a customisable ROI framework for calculating the business case for DLP investment specific to your organisation's size, sector, and risk profile. Turn breach statistics into concrete budget justifications.
The data loss prevention landscape has undergone fundamental transformation. In 2025, over 3,158 publicly disclosed data breaches exposed more than 1.7 billion records globally. The average cost of a data breach reached $4.88 million — the highest figure ever recorded by IBM's annual Cost of a Data Breach report. But the headline statistics only tell part of the story. The nature of data loss itself has changed: the fastest-growing category of data exposure is no longer external attacks or insider theft, but accidental leakage through generative AI tools, cloud applications, and collaboration platforms that employees use daily.
11% of data pasted into generative AI tools contains confidential information including source code, customer data, financial records, and strategic documents. This represents the largest unmonitored data channel in most enterprise environments.
Generative AI adoption has created an entirely new category of data loss risk that most organisations have not yet addressed. Our analysis of enterprise AI usage patterns reveals that employees across all departments — not just technical staff — regularly share sensitive information with AI tools. Legal teams paste client-privileged documents into ChatGPT for summarisation. Finance teams upload spreadsheets to AI analysis tools. Developers share proprietary source code for debugging assistance. In each case, sensitive data leaves the organisation's control and enters third-party AI systems with varying data retention and training policies.
The regulatory environment for data protection has tightened significantly. The EU AI Act, entering enforcement in 2026, introduces specific requirements for organisations using AI systems that process personal or sensitive data. GDPR enforcement actions have increased both in frequency and penalty severity, with several fines exceeding €100 million in 2025. In the United States, state-level privacy legislation continues to expand, creating a patchwork of compliance obligations that compound the complexity of multi-jurisdictional data protection.
EU AI Act enforcement begins in 2026. Organisations using AI systems that process sensitive data must demonstrate adequate data protection controls or face penalties of up to €35 million or 7% of global annual turnover, whichever is higher.
The global data loss prevention market is projected to grow at 22.3% CAGR through 2030, driven by cloud adoption, generative AI risk, and regulatory expansion. Venture capital investment in DLP and data security companies exceeded $2.5 billion in 2025, with cloud-native platforms attracting the majority of new funding. Enterprise DLP spending is shifting from on-premises solutions toward cloud-native and SaaS-integrated platforms, reflecting the broader transition of enterprise IT toward cloud-first architectures.
Organisations that have not yet deployed dedicated DLP solutions should prioritise implementation as a board-level security investment. The cost of prevention — typically $15-50 per user annually — is orders of magnitude lower than the average $4.88 million breach cost. Present this analysis alongside your organisation's specific risk profile and regulatory obligations.
