Data Breach

What Is a Data Breach?

Short definition:
A data breach occurs when sensitive or confidential information is accessed, exposed, or stolen without authorization.

What this actually means for a business:
A data breach can expose customer data, employee records, financial information, or intellectual property. Breaches often lead to downtime, legal obligations, reputational damage, and financial loss.

Common misconception:
Many people assume breaches only happen through advanced hacking. In reality, breaches are often caused by phishing emails, weak passwords, or human error.

When this matters:
If your business handles personal, financial, or regulated data, a breach can trigger compliance issues and long-term consequences.
