Symantec Data Loss Prevention Review and Alternatives

Data loss prevention (DLP), just as the name implies, is a strategy for detecting and preventing sensitive corporate data from leaving your network. The tool used to enforce a company’s data loss prevention policy is called DLP software

DLP software mitigates the risk of data leakage or data loss by monitoring, detecting, and blocking sensitive data while at rest (data that is not moving such as database, file share, etc.), in use (data that the user is currently interacting with–endpoint actions), and in motion (data traveling across a network through various communication channels–network traffic). It ensures that sensitive information is identified and risk-appropriate controls are deployed, with minimal impact on business processes.

Here is our list of the best Symantec Data Loss Prevention Alternatives:

Choosing the Right Solution: Enterprise DLP vs. Integrated DLP

Organizations looking to implement a DLP solution for their budget and functional requirements have to consider several strategies. Enterprise and integrated DLP solutions have emerged as two strategies organizations need to implement sustainable DLP strategies.

Enterprise DLP solutions are standalone products that offer comprehensive tools and policies for both data at rest and in motion, content and contextual scanning capabilities, device control, and centralized policy management and reporting, including policies to support regulatory compliance. Given the comprehensive nature of enterprise DLP products and their extensive data protection tools, many companies believe they are the only option worth considering. And, in the case of big organizations, that is undoubtedly true. But for SMBs that do not need the full capabilities of enterprise DLP tools, this can be problematic. As a result, most organizations, especially SMBs that purchase enterprise DLP, often use only a small part of their capabilities. This is where integrated DLP comes into play.

Integrated DLP solutions are primarily extensions of existing security tools that offer a cut-down version of enterprise DLP solutions while eliminating the complexities needed for large-scale networks. As a result, they cost considerably less than an enterprise DLP solution and take little time to implement. However, the risk of integrated DLP is their limited customization options and capabilities.

Organizations looking to deploy a DLP solution should first assess their needs, including areas where their data is at risk, the scope of the controls, and scalability requirements. Then, the focus should be on those actual needs when deciding which DLP option to go for.

Symantec DLP Solution

The Symantec DLP solution by Broadcom stands out as one of the leading enterprise DLP solutions out there. It comprises a single unified management platform, lightweight endpoint agent, and powerful content-aware detection products that all together provide comprehensive discovery, monitoring, and protection capabilities that give you visibility and control over your confidential data. The various product components comprise Network Discover/Cloud Storage Discover, Network Protect, Network Monitor, Network Prevent, Endpoint Discover, Endpoint Prevent, and Enforce Server.

The Enforce Server is the central management platform that enables you to define, deploy, and enforce data loss prevention and security policies. All other components—the Discover, Protect, Monitor, and Prevent modules can be deployed as stand-alone products or in combination. However, the Enforce Server is always used for central management irrespective of the stand-alone products you deploy.

The Symantec DLP solution is highly scalable and supports deployments on Windows, Mac, and Linux servers across physical, on-premises, cloud, and virtual environments, including managed services delivered by Symantec Partners. In addition, it supports cloud deployments with Symantec DLP for Cloud Storage and Cloud Prevent for Microsoft Office 365. Finally, it includes DLP monitoring for mobile devices and emails through Symantec DLP for Mobile with Mobile Email Monitor and Mobile Prevent. The various Symantec DLP components are grouped under the following solution categories:

Symantec DLP for Storage Helps organizations discover and protect data at rest across storage repositories––data stored on file servers, endpoints, cloud storage, network file shares, databases, SharePoint, and other data repositories. It does this using the following components:

  • Symantec DLP Network Discover: This helps to find confidential data by scanning network file shares, web content servers, databases, cloud, and other enterprise data repositories.
  • Symantec DLP Network Protect This automatically cleans up and secures all exposed files. In addition, network Discover detects and provides remediation options, including quarantining, moving files, or applying policy identity-based encryption and digital rights to specific files.

Symantec DLP for Endpoint As the name implies, protects data in use on endpoints. It provides complete discovery, monitoring, and protection capabilities for data in use across various channels: email, cloud apps, network protocols, external storage, and virtual desktops and servers. In addition, the lightweight endpoint agent enables two key components:

  • DLP Endpoint Discover Scans local hard drives and gives you deep visibility into sensitive files that users are storing on their systems.
  • DLP Endpoint Prevent Monitors users’ activities and gives you control over applications, devices, and platforms, including the ability to quarantine, encrypt or enforce digital right management.

Symantec DLP for Network Protects data in motion over the network. It monitors and prevents sensitive data traveling across a network through various communication channels from being leaked. It does this using the following modules:

  • DLP Network Monitor Captures and analyzes outbound traffic on your corporate network and detects sensitive content and metadata over network communication protocols.
  • DLP Network Prevent for Email Monitors and analyzes all corporate email traffic and protects them from being leaked or stolen by employees, contractors, and partners.
  • DLP Network Prevent for Web Monitors and analyzes all corporate web traffic and protects them from being leaked to the Web.

Once installed, the Symantec DLP identifies all locations that hold sensitive data and gives you the option to enforce appropriate security controls. Some of the key features and capabilities of the solution are as follows:

  • Discovers and locates confidential information in network and cloud storage repositories, on file and web servers, databases, and endpoint devices.
  • Protects brand reputation, intellectual property, and other critical data with targeted controls and policies based on user risk and data sensitivity
  • Simplifies incident triage, streamlines remediation, and detects risky behaviors and insider threats
  • Monitors network traffic, endpoints, and storage devices in real-time for transmission, use, and safekeeping of confidential data and takes immediate action toward preventing accidental exposure or sharing.
  • Delivers deep visibility of user activity across endpoints, storage repositories, networks, cloud apps, email, and the web, including Shadow IT.
  • Reduces complexity with a single unified platform for on-premises and hybrid cloud environments
  • Continuously monitors and protects sensitive data from a potential breach and automatically enforces appropriate security controls.
  • Provides templates and workflows for compliance with security and privacy standards such as HIPAA, GDPR, PCI DSS, and others.
  • Combines DLP with user activity tracking, giving it an additional security boost.

The Symantec DLP is a highly scalable solution best suited for enterprise-oriented customers, and it integrates well with other Symantec security products and tools. However, it has no trial version and flat-rate pricing fees advertised, so there is no way to try it out before buying a subscription license. Instead, you need to contact Broadcom or its reseller partners directly for trials and pricing details.
