4 Ways to Prevent Insider Threats with Microsoft Purview

Introduction

You might have heard of the book, “Eat that Frog”. 

The phrase “Eat that Frog” means something that is difficult to face, but one must do it anyway. Experts suggest that we must start with the most difficult task. 

So, before we dive in, I have a few challenging questions for you. 

Has your organization ever encountered issues with certain employees? Or, to put it another way, do you suspect any employee might be harboring grudges against the organization? 

If your answer is yes, then what did you do to clear the air? 

If there are disputes in the past that were not handled efficiently, then your organization’s sensitive data might be at a huge risk of insider threat

On the other hand, if your answer is no, your organization may still face insider risks despite having a strong workplace culture. Data leaks or breaches can occur due to rookie mistakes or accidents.

Insider Threat Risk and Data Exfiltration Landscape

Insider threats and data exfiltration can arise from various factors, including financial gain, revenge, or ideological beliefs. They can also be unintentional, such as when an employee accidentally exposes sensitive data or breaches a security policy.

Crowd Research Partners reports that 90% of organizations feel vulnerable to insider attacks due to factors like excessive access privileges, an increased number of devices accessing sensitive data, and the growing complexity of IT systems. Additionally, 53% of organizations have confirmed insider attacks within the past year.

According to the Ponemon Institute’s 2022 Cost of Insider Threats: Global Report, the average cost of an insider incident is $11.4 million, and the average time to contain such an incident is 77 days (about 2 and a half months). 

These statistics underscore the importance of Insider Risk Management (IRM). Implementing effective IRM practices can provide organizations with significant advantages. 

  • Reduced risk of data breaches and other security incidents  
  • Improved data protection and privacy  
  • Lower costs associated with insider incidents  
  • Enhanced employee awareness and accountability 

It all boils down to organizations struggling with a fragmented solutions landscape. 80% of decision makers purchased multiple products to meet compliance and data protection needs.
