Use the free data breach cost calculator to understand the financial impact of cyber attacks
Data breaches are more than just a security issue, they’re a financial disaster waiting to happen. If the worst-case scenario occurs, does your organisation know what the costs of a data breach could add up to? Many businesses are reluctant to think about this, leaving them unprepared for the financial impact of a cyber attack.
According to the IBM Cost of a Data Breach Report 2026: UK findings explained, the average cost of a data breach in the UK reached £3.13 million in 2026, down slightly from £3.29 million in 2025. At the same time, Cybersecurity Ventures projects that global cybercrime costs will climb to $12.2 trillion annually by 2031, as attacks grow more frequent and more costly to contain.

Whether you’re a small business or a large enterprise, understanding these costs is the first step toward better cyber security preparedness.
