Discover the best DLP solutions on the market today. Uncover how these security solutions work to support organizations in protecting their sensitive data from unauthorized access, use, or disclosure.  

The stakes are high when it comes to data loss. Data breaches cost organizations millions of dollars every year, with a global average cost of $4.24 million according to the IBM Cost of a Data Breach 2021. Despite advancements in cybersecurity, it’s still no easy task to protect valuable business information.

Poor data storage and data security can lead to serious losses. There are a number of ways data can be lost or stolen – including phishing, ransomware, data exfiltration, and insider threats, to name the most common. With a robust data loss prevention (DLP) solution in place, organizations can offer better protection to sensitive data stored in their databases.

In this article, we’ll consider the best DLP solutions on the market for data loss prevention. Some of the key features to look out for are their compatibility with relevant regulatory frameworks like HIPAA or GDPR. You also want to find a solution that protects all of your data, wherever it is, without putting up too many barriers for your users. Otherwise, productivity will be affected, and employees may decide not to implement the proper security protocols to save time.
