Key Features of DLP Software

While each DLP takes a different approach to the task, these are the key features common to all of them.

Data classification

Before teams can protect data, they must know which data is sensitive and monitor the way it’s handled. Data classification allows businesses to locate and identify all their sensitive information to then determine if it’s being appropriately used and accessed. Some DLP solutions also provide intellectual property classification so organizations can track all their IP.

Data visibility

Data visibility goes hand-in-hand with classification. Businesses should observe the activities surrounding their data, including user interactions that can include access to data platforms and storage solutions as well as tracking data as it moves through different file sharing solutions or emails.

Compliance features

Data loss prevention plays a big role in regulatory compliance. Businesses need to track their progress in meeting local and international standards, and DLP tools should provide features to help them do that. For example, a healthcare team might receive alerts when a particular storage system isn’t compliant with a particular article of HIPAA.

End user management

DLP solutions often don’t just manage data—they manage users as well. By restricting user actions based on enterprise policies, DLP software helps protect the movement and storage of data.

Network monitoring

Some DLP products look for vulnerabilities within a network to determine what could be dangerous for enterprise data. When DLP software alerts teams to strange activity in the network, they can better determine if that traffic poses a threat to sensitive data. 

How to Choose the Best DLP Software for Your Business

When your data, security, or executive teams are evaluating DLP solutions, the following steps can help you choose the most suitable product:

  • Consider your budget. Is a particular DLP solution affordable? Does it have any necessary add-ons, and if so, how expensive will those be?
  • Identify your team breakdown. Is your data team experienced, or is it mostly junior employees? Solutions with more granular controls and additional features may be more suitable for large, experienced teams. Small businesses should pick an easy-to-use tool with a straightforward interface.
  • Choose a solution that integrates with existing systems and applications. The data you need to protect often resides on these platforms, so you’ll want the DLP product to support as many of them as possible or have an API for configuring integrations.
  • Prioritize the features your data and security teams need most. We recommend choosing three to five capabilities that your ideal DLP product must have, based on your business needs, and narrowing the list down to ones that have these.

Frequently Asked Questions (FAQs)

We’ve compiled a list of commonly asked questions and answers about data loss prevention. 

What is the difference between DLP and EDR?

While DLP is focused specifically on data, endpoint detection and response (EDR) focuses on end users and devices, identifying and remediating the threats that come from them. While EDR can certainly help protect data, it is a more general technology—it prevents the spread of malware through company systems. It’s not only designed to prevent data loss, though that’s one of its use cases.

What triggers a DLP incident?

This entirely depends on the individual organization’s rules. Administrators set policies—for example, a .CSV of a Salesforce table may not be shared through email with anyone who has an email domain outside of the company. If someone performs that action anyway, the DLP software triggers an alert. That alert could go to an admin’s email account, trigger a Slack workflow, or some other preconfigured incident notification.

Who is responsible for DLP?

This also depends on the individual company, but often, data loss prevention is governed by one of the following:

  • Chief compliance officer
  • Dedicated data protection team
  • IT manager
  • Security team

Often, the company size and organizational structure will determine who governs DLP. Small businesses likely won’t have a dedicated data protection team, and a compliance manager or in-house IT team might manage all data protection initiatives. But a large enterprise might have a few employees dedicated to DLP alone.

Bottom Line: DLP solutions

Data loss prevention software helps data and security teams manage the flow of data between applications and users. While they aren’t a set-and-forget solution, DLP tools provide more insights for businesses that aren’t sure how to centralize and monitor information. Data loss prevention is one of the most critical strategies a business can implement to protect one of its most important assets.
