What Are Common Causes of Data Breaches?

Most data breaches arise from human error, poor security practices, or inadequate technical safeguards. Common causes include:

• Weak or shared passwords

• Phishing or social engineering scams

• Loss or theft of devices or documents

• Unencrypted data storage

• Sending emails to incorrect recipients (BCC errors)

• Unauthorised system access by staff

Mitigating these risks requires continuous employee training, strong authentication measures, and routine data protection audits. A proactive approach not only prevents breaches but also strengthens organisational resilience.
