What Makes Data Breaches Dangerous?
A data breach occurs when unauthorized individuals access sensitive information stored by organizations. This can be likened to a digital break-in, where personal details are stolen instead of physical items. Commonly stolen data includes:

- Personal healthcare information
Criminals can exploit this information for identity theft, fraudulent purchases, or targeted phishing attacks. The sooner you identify a breach, the better your chances of mitigating these risks. Source
