What Is Data Loss Prevention and How Does It Work

It is considered that Data – Loss – Prevention (D-L-P) is a strategy that is used by organizations with the purpose to guarantee the security of the data in company systems. All the same, D-L-P tools and software are intended to filter and observe the data in real-time. In addition to processing the data used, stored, and transmitted over the network, D-L-P programs ensure that no harmful external data enters the company’s network. Its main purpose is to protect sensitive company records from all incoming data that threatens the organization, as 70.5% of customers have lost data due to unintentional removal, or system failure.

What is Data Loss Prevention?

D-L-P is determining as a practice and tech – which confirms that the critical and crucial company data not getting lost or open-up to unauthorized operators. This means that sensitive data are classified into different parts. These categories are related to D-L-P policies that an organization can define.

  • Monitoring: D-L-P tools provide data visibility, end-to-end functionality, and system access through business networks and cloud services for data protection at rest, on the go, and in use
  • Reporting: The tools provide recording and reporting useful for responding to events and audits
  • Analysis: Tools can identify vulnerabilities, data breaches and thefts, and suspicious behaviour by providing a security context for security forces

How Does DLP Work?

D-L-P is a process and technology that automatically detects, monitors, and protects sensitive data when it is “in use” (such as email) or in “sleep mode” (such as the cloud, desktop, or laptop). Creating a D-L-P policy determines which sensitive data you want to protect, where it is located, and how you want to protect it. However, D-L-P then uses software to automatically block access to certain documents or send e-mail, for example. You can consider D-L-P as a data network security expert, with the capabilities of networking and CCNA Security certification training – who closely monitors your entire IT environment, detects and prevents unauthorized use and transmission of sensitive data.

How to Develop A DLP Strategy

There are several steps to take to initiate a D-L-P strategy. The below-mentioned contains some high-level guidelines that your DLP structure should follow.

  • Give priority to your data – Decide which data would be the biggest problem in case of theft.
  • Sort the data – Use the continuous data distribution tag to track usage.
  • Understand when data is most at risk – The data show different levels of risk depending on their location.
  • Monitor all data transfers – It is important to understand how the data is used and to recognize the current behaviour that is risking the data.
  • Development of communication and supervision – To reduce the risk of data, create controls and pass them on to the team. This can be easy at the beginning of a D-L-P initiative, given the most common risky behaviours.
  • Train staff and provide ongoing advice – User training is crucial and reduces the risk of data loss on your D-L-P system.
  • Roll out – Preventing data loss is an ongoing process, not a step-by-step process! Start small and expand as needed.

The Importance of D-L-P

D-L-P is a term used to protect technology from protecting confidential data from unauthorized persons. D-L-P systems monitor available data, movement times, and try to prevent real-time data exploitation. Why is DLP important? However, the technology is based on algorithms that decide which data to block. Growing concerns about corporate intelligence; computer security breaches; and changes to privacy obligations is a mandatory business component for D-L-P technology firms.

One aspect of the D-L-P workflow requires communication with other systems. The protection is based on other data to determine which information may be transmitted. Well-established protocols are often used to exchange file creation data using D-L-P technology; however, it is not usually associated with the specific contents of each file. Files may require different levels of security, depending on their content. D-L-P can never allow the transfer of certain data outside the company, while other transfers may be allowed, but only under limited conditions.

Numerous companies rely on newly created files to create and assign “tags” to their customers. The level of sensitivity of the data can be based on the user’s classification, which helps determine the level of sensitivity of an individual file or part of it. However, manually assigning users is often an inaccurate and inefficient process because it reduces employee productivity. Using technology for automatic document distribution can advance the performance of D-L-P technology.

Reasons – Why D-L-P Is Crucial For Businesses

Let’s take a closer look at why D-L-P is considered an absolute necessity for companies of all sizes.

Increased External Threats and Attacks

Companies take data loss seriously. As data theft becomes more complex every day and new ways to access networks are increasingly found, companies are under increasing pressure to continue searching for data bugs.

Internal Threats

Dissatisfied employees are a great example of an internal threat – individuals with the intent to harm companies from within.  Because they already have access to the data and may have sensitive information about different employees in the company, an attack can be more dangerous than trying to break out of the organization. 

Random Exchange of Information

That person must not intend to harm the company or compromise business information. They can easily fall victim – by a method used by data hackers. They usually investigate the target (organization) and choose the victim (employee) for the purpose. They always try to accidentally pass on unknown information to the victim.

Poor B-Y-O-D Maintenance

B-Y-O-D principles have helped many industries work more efficiently. However, there are still industries that have not implemented it at all or have found and maintained a B-Y-O-D solution poorly. Unfortunately, this makes it easy for employees to unexpectedly share sensitive data via their phones and tablets. If you don’t have proper security measures and run into repeated attacks, your business can quickly become a bad name.

Cloud Storage and Services

While we discussed the challenges of BYOD, it should also be noted that employees can use their storage device and personal web storage services to store and share confidential information in their organization. It is possible, especially in non-technology companies, that these people do not know the right protocols.


It is reflected that D-L-P is something that new companies should pay special attention to when starting a business. All new data created, stored, used, and shared from day one is sensitive information. Laying a solid foundation – in the beginning – means a little less anxiety on the way to success. It is the responsibility of the company to establish special cybersecurity measures to ensure that employees have the right to access the data – within the company’s networks.
