Top Data Loss Prevention (DLP) Solutions

In an age of strong data privacy laws like GDPR and CCPA, data loss prevention (DLP) technology is becoming a critically important IT security tool.

Every organization has data, and some of that data is more sensitive than others. Sensitive data can include personally identifiable information (PII) that can impact user privacy. Sensitive data also includes payment and financial information that could lead to identity theft and fraud if the data is lost or stolen and winds up in the wrong hands. Other critical sources of data include intellectual property (IP) and trade secrets.

How DLP Works

DLP technology provides a mechanism to help protect against sensitive data loss—and thus could also be something of a mitigating factor when dealing with compliance agencies in the wake of a data breach. As such, DLP has become a top IT spending priority in many organizations.

By classifying data and users and identifying or blocking anomalous behavior, DLP tools give enterprises the visibility and reporting needed to protect sensitive data and satisfy compliance reporting requirements.

Key DLP Trends

A number of trends are all driving an increase in DLP adoption and strategic importance – and in some cases changing how DLP is delivered and deployed.

The Great Resignation

Businesses are currently struggling with the number of workers leaving for alternate employers. Often leaving with them is the sensitive data that fuels the business. Whether intellectual property or regulated data, employee flight creates a situation where data loss or theft is more prevalent and more costly.

Hybrid Work Model

Prior to the COVID-19 pandemic, the common model was to have the vast majority of employees within the office and in a controlled technology environment. That model has flipped in favor of remote work and won’t likely ever fully return to the way it was. More workers in more locations means more sensitive data in more locations – and more potential points of data leakage.

Cybersecurity Talent Shortage

Hiring, training, and retaining the staff needed to effectively run an information security program can be a challenge for any size business given the cybersecurity talent shortage. Relying on a third party like a managed security service provider (MSSP) to be your eyes and ears delivers the simplicity and efficacy needed for an effective data protection program. Like other security defenses, DLP is also increasingly being offered as a service.

Cloud Security Platform Delivery

The cloud delivery model has proven itself to be efficient and often more secure than what companies can deliver on-premises relying on their own resources. Cloud-delivered DLP, or DLP as a Service, eliminates the complexity and overhead that can burden IT teams.

Platform Consolidation

Organizations rely on an ever-increasing stack of security vendors. This increase in vendors leads to excess complexity – and often reduced information security. Consolidating internal and external data protection programs with a single solution delivers a simplified view that analysts can use to achieve their main goal, which is to protect sensitive data.

Data Explosion

IDC estimates that by 2025, 463 exabytes of data will be created every single day. Information security teams have a rapidly expanding challenge to find, understand, and protect all that data. Whether it be on the endpoint, in the cloud, or somewhere in between, data protection programs are a critical piece of the solution to stop data loss or theft.

Profiling

Customers and companies are moving away from the registration model. Maintaining spreadsheets with millions of rows to identify PII is too difficult to maintain and secure, especially as customers are moving to a profiling mode of operation.

DLP capabilities

There are a number of key capabilities that the top DLP products and services support.

  • Cloud: The DLP market, much like the broader IT market, has been shaped in recent years by the rise of the cloud. No longer is enterprise data confined to on-premises deployment. DLP solutions therefore must monitor sensitive data in the cloud.
  • Privacy compliance: With GDPR, CCPA, and other data privacy regulations on the rise, DLP has become a useful tool for helping organizations protect customer privacy.
  • Data labeling: DLP tools have long enabled users to self-assess and identify what types of data should be protected.
  • Machine learning: Among the latest advances in DLP is machine learning capabilities that automatically identify potentially sensitive information, so it can be protected.

How to choose a DLP solution

When choosing a DLP technology or services, there are several key considerations organizations must take into account, including:

  • Scope: Where is the data that needs to be protected, and does the solution you’re looking at have full visibility into those deployments?
  • Compliance: If the DLP service is being used to help enable regulatory compliance, be aware of integration with GRC (governance, risk, and compliance) tools.
  • Reporting: It’s important for some organizations to have visibility and reporting into what data is protected and how it is being accessed, particularly for compliance purposes.

After reviewing the market for DLP solutions, here are eSecurity Planet’s top picks for DLP.

Digital Guardian

Digital Guardian

The Digital Guardian Data Protection Platform by HelpSystems, powered by AWS, performs on traditional endpoints, across the corporate network, and on cloud applications, making it easier to see and block threats to sensitive information.

Cloud-delivered means simplified deployment, cross platform coverage for no gaps, and flexible controls to stop risky behavior. And available either as a software-as-a-service (SaaS) or managed service deployment, Digital Guardian gives deployment flexibility.

Key Differentiators

  • Digital Guardian supports both a use case-based approach (known data types or user groups) or a data risk discovery approach (identifying unknown use cases).
  • Users can gain visibility into their data by seeing where sensitive data is located, how it flows in the organization, and where it is put at risk, all without policies.
  • Users can benefit from rapid deployment, reduced overhead, and instant scalability.
  • DLP coverage is available for all endpoints, browsers, and apps.
  • Controls are able to align data protection programs with business needs. These controls include log, alert, prompt, block, and encryption.
  • The platform can be deployed as a fully managed security service program (MSSP) with a 24/7 global analyst team.
  • Users can discover, classify, and protect data throughout the extended enterprise via an endpoint agent that can be installed on Windows, Mac, or Linux machines or a network appliance, either physical or virtual.
  • All data-centric events collected are reported up to the Analytics & Reporting Cloud (ARC). This web-based console, powered by AWS, correlates and analyzes system, user, and data events from endpoint agents and network appliances to provide the visibility and context to identify and remediate insider and outsider threats.
  • Digital Guardian provides intellectual property and regulated data protection.
