Mistakes can happen to anyone even with the most knowledgeable hence data governance solutions play an important role in reminding everyone accessing sensitive data by notifying or requesting approval or blocking sharing activity. Solutions such as Microsoft Purview can be implemented to mitigate data leaks as well as improve data protection across the organisation.

my 2 cents: in addition to training, your company certainly needs to start to invest DLP tools (Data Loss Prevention) to automatically catch sensitive information before it leaves company systems.

Here are some strategies: 1. Comprehensive Training and Awareness Programs: Regular training:Conduct frequent training sessions to educate employees about data security best practices, including proper handling of sensitive information, recognizing phishing attempts, and understanding the potential consequences of data breaches. Simulations and drills:Use simulations and drills to test employees knowledge and response times in real-world scenarios. Consequences of breaches: Emphasize the severe consequences of data breaches, both for the company and for the employees involved. 2. Strong Access Controls and Privileged Access Management: Least privilege principle: Grant employees only the minimum access necessary to perform their job duties.

Data Loss Prevention (DLP) is a highly effective solution for preventing the accidental leakage of sensitive data. However, for DLP to function optimally, data classification and labeling must be implemented. When an organization has robust data classification and labeling schemes supported by clear policies, users are better informed about which data needs protection. Moreover, the effectiveness of these measures is significantly enhanced when users are well-aware of the importance of data protection, the consequences of data breaches, and the potential impacts on both the organization and individuals.

Awareness is key! Give regular training so people know the importance. Explain the why really clear. And use technical Data Loss prevention solutions. So you prevent it from happening accidentally.
