In 2006, when Clive Humby coined the phrase “Data is the new oil”, the world couldn’t see the extensiveness or the magnanimity of the quote. Now, 14 years later, the world has slowly come to realize the true power of data. But, in today’s data-dependent age, the world is also vulnerable to cyber-attacks and data theft. This problem is common for organizations of all sizes – big or small. Helping these organizations keep their data safe and secure are various Data Loss Prevention Software(s).

So, what is a Data Loss Prevention Software?

A Data Loss Prevention Software can be defined as a security platform that prevents the destruction of sensitive data by implementing various security and monitoring policies. This is done by a set of processes and tools that make sure that no data is misused, lost or accessed by any unwanted personnel. To further ensure security in every step, a Data Loss Prevention Software segregates data under various categories like confidential, regulated, business-critical among others. These categories are then implemented with different organizational and regulatory compliances like the PCI-DSS, GDPR, or HIPAA. The Data Loss Prevention Software is always on the lookout for activities across control endpoints and corporate networks, ensuring and enforcing remedial action with alerts, encryption, and other protective actions to save data from being maliciously shared.

What are the different types of Data Loss Prevention Software?

Much like different management technologies, a Data Loss Prevention Software can be broadly divided into two categories: Enterprise Data Loss Prevention Software and Integrated Data Loss Prevention Software.

The Enterprise Data Loss Prevention Software offers a comprehensive solution that is packaged as the agent software across desktops, servers, physical and virtual appliances that are used as soft appliances for data discovery or monitoring network of email traffic. 

An Integrated Data Loss Prevention Software on the other hand is limited to secure web gateways (SWGs), enterprise content management (ECM) platforms, email gateways (SEGs), cloud access security brokers (CASBs), and email encryption products.

So, how does a Data Loss Prevention Software work?

A Data Loss Prevention Software works in synergy with numerous key technologies that ensure the software identifies sensitive data and adopts the requisite remediation action to prevent any unfavourable incidents.
