Network vs. Cloud vs. Endpoint DLP

September 26, 2023 No Comments

by Mo Amao

Organizations utilize a combination of procedures and tools called data loss prevention (DLP) or data leak prevention to safeguard their data against accidental loss or nefarious tampering. DLP also ensures businesses comply with important frameworks and laws like SOC 2, PCI DSS, HIPAA, and other top standards. Its significance is further demonstrated by the fact that under ISO 27001:2022, sensitive data-handling organizations are now required to implement a DLP instrument. The classification of regulated, confidential, and business-critical data is done by data loss prevention software. Additionally, it highlights policy violations, aiding organizations in swiftly fixing breaches and preventing end users from maliciously or unintentionally revealing information that could endanger the organization.

Data Loss Prevention also offers reporting to satisfy compliance and auditing needs and pinpoint forensics and incident handling problems. The three main areas of the company’s digital environment where DLP can be applied are endpoint, network, and cloud systems. All the modalities safeguard various user and data kinds. But the question is, which kind of DLP is more efficient? Should you prioritize Endpoint, Cloud, or Network DLP?

For many organizations, monitoring end user access to sensitive information, as well as the movement of this data is an essential part of their cybersecurity program. Before the ubiquity of cloud platforms and hybrid work this was done with an on-premises data loss prevention tool. Today, the category has been forced to evolve to address the challenges of distributed workforces, but this transformation has been slow and not uniform across the industry.

In this blog post, we’ll examine each strategy’s main distinctions, benefits, and factors to consider.

Network DLP: To Secure the Gateway

The earliest and most established type of DLP is network DLP. It focuses on monitoring and managing data moving around a company’s network. Network DLP performs the following functions:

– Monitoring Traffic: Network DLP solutions inspect traffic as data packets pass through an organisation’s network infrastructure. Based on specified policies, they examine the content of these packets to identify sensitive information.

– Enforce Policies: Network DLP systems can enforce policies to restrict, quarantine, or encrypt sensitive data in real-time as it is discovered. This helps to prevent data breaches and leaks before they occur.

The benefits of network DLP include:

– Early Detection: Network DLP mitigates threats before they enter your organisation’s environment by detecting and preventing data breaches at the network gateway.

– Centralised Control: Organisational policies can be enforced consistently across the entire network, ensuring uniform data protection.

– Ensure Compliance: Network DLP assists with compliance by tracking and regulating data as it flows throughout the network.

However, Network DLP does have some limitations. In addition to being unable to protect data on endpoints or in the cloud, it may need help handling encrypted communication; deployment and upkeep of Network DLP solutions are pricy, complex, and resource intensive.

Cloud DLP: To Secure Data in the Cloud

With the growing use of cloud services, it is essential to safeguard data wherever it is processed and stored. Cloud DLP primarily protects data in cloud infrastructures like AWS, Azure, or Google Cloud. Here is how it works:

– Content Inspection: Cloud DLP tools scan documents and digital information kept in cloud storage spaces like S3 buckets or SharePoint. Based on predetermined policies, they categorise and identify sensitive data.

– Policy Enforcement: When sensitive data is discovered, Cloud DLP can take precautions to reduce the risk of data disclosure, such as encryption, quarantine, or alerting.

Benefits of Cloud DLP

– Cloud-Centric: It is designed specifically for cloud environments and ensures data security in the cloud.

– Integration: Cloud DLP systems frequently smoothly link with well-known cloud providers, facilitating implementation and management.

– Visibility: Cloud DLP offers information on how cloud services use and expose data.

Cloud DLP is a great option for businesses that rely extensively on cloud technology. It does not, however, protect data stored on endpoints or outside of the cloud.

Endpoint DLP: Protecting Data Where it Resides

When it comes to individual devices like laptops, desktop computers, and mobile devices, endpoint DLP is all about protecting data wherever it is created, stored, or utilised to ensure endpoint security. This is how it works:

– Content Monitoring: Using specified policies, endpoint DLP software examines files and data on specific devices to identify sensitive material.

– Users may be prompted to choose how to handle sensitive data through encryption or access limitations.

Endpoint DLP’s benefits include:

– Data at Rest Protection: This safeguards data even when it isn’t actively being sent between devices or kept in the cloud.

– User-Centric: Endpoint DLP equips users to take charge of decisions about data protection.

– For mobile devices, offline protection is essential because it operates without the need for network connectivity.

However, in large organizations with many devices to monitor and secure, Endpoint DLP can take time to administer.

Choosing the Right DLP Strategy

An organization’s needs, architecture, and compliance constraints will determine whether to use Network, Cloud, or Endpoint DLP. A mix of these methods is frequently the best course of action. Here are some things to consider before choosing:

– Data Lifecycle: Recognise how and where data is most vulnerable as it moves through your organisation. Combining network, cloud, and endpoint DLP could be required to cover all data lifecycle phases.

– Consider the compliance standards and industry laws your organisation must follow. Certain rules may require specific DLP strategies.

– Cloud Adoption: If your company uses cloud services frequently, cloud DLP is crucial for protecting data in those settings.

– Endpoint Diversity: The quantity and variety of endpoint devices in your company may impact whether Endpoint DLP can be successfully implemented.

Assessing your organisation’s resources—including finances, personnel, and technological know-how—will help you choose how to best implement your DLP plan.


In conclusion, there is no one-size-fits-all solution for network, cloud, or endpoint DLP. Every plan has advantages and disadvantages, and the best course of action for your company will depend on a detailed examination of your unique requirements and circumstances. Regardless of your decision, the primary objective still stands: protecting sensitive data in a constantly changing digital environment.
