Market presence criteria we used for the comparison

AIMultiple has selected three key criteria that companies can use to narrow down their options when searching for the right DLP tool for their business.

1. Number of reviews

The volume of reviews for a DLP vendor is a key indicator of its user base and, therefore, the maturity of its solution.

2. User ratings

High user ratings from B2B platforms like G2 and TrustRadius indicate user satisfaction.

3. Number of employees

A larger number of employees is correlated with more mature solutions.

Some common features your DLP software must have:

• Data Discovery (+ optionally Data Classification): Without this, your DLP software won’t be able to identify and locate sensitive data within an organization’s network, systems, and storage repositories.
• Supported OS: Without support for widely-used operating systems, your DLP software will face compatibility issues, reducing its overall effectiveness and reach across organizational environments. Universal support for Windows is critical, as it dominates enterprise environments and safeguards the majority of endpoints. MacOS compatibility is equally essential, serving creative industries and organizations where Apple devices are prevalent and helping prevent data leakage from an increasingly significant user base. Similarly, Linux support is crucial for securing sensitive data on servers and systems used in technical and operational environments. Without cross-platform compatibility, critical gaps in data protection could expose enterprises to vulnerabilities and compromise their security posture.
• Content Inspection and Analysis: Without this feature, your DLP tool cannot examine data content to detect sensitive information or policy violations.
• Endpoint Protection: Without this, your DLP software won’t be able to secure data on user devices, leaving endpoints vulnerable to data breaches and unauthorized access.
• Network Monitoring and Control: Without this feature, your DLP tool won’t be able to monitor and control data in transit across your network, making it difficult to prevent data leakage over network channels.
• Cloud Data Protection: Without this, your DLP software will be unable to safeguard sensitive data stored or processed in the cloud, thereby exposing it to potential threats.
• Data Encryption and Masking: Without this feature, your DLP tool will be unable to protect data by encrypting or masking sensitive information, leaving it vulnerable to unauthorized access.
• Policy Management and Enforcement: Without this, your DLP software won’t be able to define, implement, and enforce data protection policies across your organization.
• User Behavior Analytics (UBA): Without this feature, your DLP tool will be unable to analyze user activities and detect anomalous behaviors that may indicate insider threats or compromised accounts.
• Data Movement Monitoring (USB, Email, Web, etc.): Without this, your DLP software cannot track and control how data is transferred via removable media, email, or web uploads, thereby increasing the risk of data exfiltration.
• Incident Response and Reporting: Without this feature, your DLP tool won’t be able to provide alerts and reports on data security incidents, hindering your ability to respond promptly to breaches.
• Compliance Management: Without this, your DLP software won’t be able to help your organization meet regulatory compliance requirements by enforcing relevant data protection standards.
• Integration with SIEM/SOC Tools: Without this feature, your DLP tool will be unable to integrate with Security Information and Event Management (SIEM) or Security Operations Center (SOC) tools, thereby limiting your overall security visibility and response capabilities.
• Contextual Data Protection: Without this, your DLP software won’t be able to consider the context (such as user role, data type, and location) when protecting data, leading to less effective data security measures.
• Role-Based Access Control (RBAC): Without this feature, your DLP tool won’t be able to restrict data access based on user roles, increasing the risk of unauthorized data access within the organization.
• User remediation and Quarantine Mechanisms: Without this, your DLP software won’t be able to automatically isolate or block access to sensitive data when threats are detected, delaying incident containment. And without the user remediation feature, specific users (Who have the power to remediate) will not be able to bypass particular policies that do not apply to them.

Guidelines to narrow down your DLP software options

1. Decide the focus of the solution

There are DLP solutions suitable for Endpoint, Cloud, or Network DLP. Identify which environment in your organization needs to be prioritized, and evaluate solutions accordingly.

2. Prepare a shortlist

The feature and market presence metrics, as well as a summary of user reviews, featured above, can help you narrow the list to 3-5 best-fit solutions for your business. You can use the common features checklist we created.

3. Understand pricing

Understanding the pricing structure of DLP software involves examining usage-based pricing, annual subscriptions, and custom pricing options. The costs should align with the organization’s budget and data protection requirements, and should grow reasonably as the organization expands.

4. Take advantage of the free trial

Most DLP solutions offer free trials, which allow hands-on experience with the DLP tool to assess its suitability in protecting data across multiple systems, including unstructured data and cloud DLP needs. If the vendor doesn’t offer a free trial, a demo can help understand the software’s capabilities in content inspection, adhering to DLP policies, and meeting specific data loss prevention criteria.

Best practices for implementing a DLP solution in your business

Once you have found the right product and vendor, consider the following best practices while implementing it in your system.

1. Data understanding

It is essential to comprehend the data within various departments within the organization. The information security teams need to communicate with multiple departments to understand the types of data that require protection and which documents are considered confidential. This will help the implementation team in creating policies and rules for data classification.

2. Policy development across all data flows

Now that you understand the data types, ensure that the DLP policies in the solution cover all aspects of data protection, including data classification, user roles, and access levels. They should also address how data is handled, transmitted, and stored. Policies must be clear, enforceable, and regularly reviewed to ensure they remain practical and relevant.

3. Employee training and awareness

Employee training and awareness drive day-to-day DLP outcomes more than tool selection alone. Employees should be educated about the importance of data security, the specific policies in place, and their roles in protecting sensitive information. Regular training sessions and awareness programs can help ensure that employees understand and adhere to DLP policies. For the product implementation, you can ask the vendor to provide demos.

4. Monitoring and incident response

Continuous monitoring and a defined incident response workflow are required for a working DLP program. DLP software should be configured to monitor data flows and detect potential data breaches or policy violations. An effective incident response plan should be in place to quickly address any data loss incidents, mitigate damage, and learn from these incidents to prevent future occurrences.

5. Regular audits and updates

Regular audits and software updates keep the DLP rule set aligned with current threats and changing business processes. Regular audits help identify any gaps or weaknesses in the DLP implementation and ensure that policies are being followed. Updating the DLP software and policies based on audit findings, emerging threats, and changes in business processes keeps the DLP program effective against current risks.

Why is it important to use DLP software?

Data Loss Prevention (DLP) software helps protect sensitive data, including financial data, personally identifiable information (PII), protected health information, and intellectual property.

1. Data protection from external threats

DLP solutions are designed to prevent data breaches and data leaks, thereby safeguarding this sensitive data. By utilizing data classification and exact data match techniques, DLP tools ensure that critical information is not inadvertently exposed or accessed by unauthorized parties.

2. Regulatory compliance and auditing requirements

As privacy regulations tighten across regions, DLP supports compliance by enforcing policies that match local rules (GDPR for the EU, HIPAA for US healthcare, PCI DSS for cardholder data).

Compliance and auditing requirements can vary significantly depending on the industry and location; however, many DLP solutions, including those from vendors such as McAfee Enterprise and Trellix DLP Endpoint, are equipped to handle a diverse range of standards.

These solutions facilitate content review and enforce DLP policies based on predefined criteria, which is crucial for complying with regulations and avoiding potential legal consequences and fines.

3. Preventing data loss and mitigating insider threats

Data loss can occur not just through external attacks but also due to insider threats, whether malicious or accidental. DLP software solutions, such as Digital Guardian and Endpoint Protector, offer comprehensive monitoring of data movement within an organization’s network, including multiple systems and cloud storage.

Data visibility and exfiltration control are how DLP tools reduce both insider risk and accidental data loss.

FAQs

Data Loss Prevention (DLP) software is a security tool used by organizations to prevent unauthorized access to, and transmission of, sensitive information. DLP software works by monitoring, detecting, and blocking sensitive data in use (endpoint actions), in motion (network traffic), and at rest (storage).

It employs rules and policies to classify and protect confidential and critical data so that unauthorized end users cannot accidentally or maliciously share data and put the organization at risk.

DLP (Data Loss Prevention) software implementation often fails due to:
– Poor preparation: The security team doesn’t assess the organization’s data flow and risks before deployment.
– Inadequate data monitoring: Policies are created without understanding how data moves within the organization.
– Lack of process and people alignment: System improvements aren’t supported by staff training or updated processes.
– Failure to customize: Organizations rely on default configurations instead of tailoring the solution to their needs.
– No continuous monitoring: DLP systems are not updated or adjusted regularly to meet evolving threats.
