  • Machine Learning/AI: It comes pre-installed with hundreds of patterns of known risky behavior. It then baselines normal user behavior so that, over time, it automatically identifies sudden, high-risk behavior changes. They say you can see the system improve in two weeks.
  • Indicators of Intent: Through its patented metadata collection and analytics engine, the DTEX platform surfaces abnormal behavioral “indicators of intent” to mitigate the risk of data and IP loss from critical systems.


  • Limited Monitoring Capability: The program has limited monitoring capabilities, such as no screenshots, keystrokes, clipboard monitoring, etc. It mostly captures file upload/download activities.
  • False Positives: Some users on G2 have reported false positives that led to employees being mistakenly marked as potential security threats. The ML has to be trained over time to reduce false positives.
  • No Prevention, Only Detection: DTEX inTERCEPT has no rule actions or prevention features. It can only display indicators of compromises but cannot actively prevent them.
  • Limitations in Alert Management: Limitations in managing alerts within DTEX could potentially impact the alert system’s effectiveness. Enhancements in alert management capabilities could help organizations better respond to security threats and policy violations.

How To Select the Best DLP Tool for Your Organization 

When selecting the best DLP tool for your organization, it’s essential to consider several factors to ensure that the solution aligns with your security needs and business objectives. 

Here’s a detailed breakdown of the steps and considerations involved:

  • Understand Your Data. Before choosing a DLP tool, it’s crucial to clearly understand the types of data your organization handles. Identify where your data resides, how it moves within and outside your organization, and its sensitivity level. This will help you determine the scope and scale of the DLP solution needed.
  • Define Your Data Protection Goals. Outline what you aim to achieve with a DLP tool. Goals may include protecting intellectual property, complying with regulations (like GDPR and HIPAA), or preventing data breaches. Clearly defined goals will guide your choice of features and capabilities in a DLP tool. 
  • Evaluate Key Features. Different DLP tools offer various features, and selecting the right tool depends on the features that best meet your needs. Essential features to consider include:
    • Content discovery. Ability to scan and identify sensitive data across various locations. 
    • Data monitoring. Real-time monitoring of data usage and movement. 
    • Incident response and alerts. Automated responses and alerts for policy violations. 
    • Integration capabilities. Compatibility with your existing security tools and IT infrastructure. 
    • Ease of policy enforcement. Tools should facilitate straightforward policy creation and enforcement. 
  • Consider Deployment Options. DLP solutions can be deployed on-premises, in the cloud, or as a hybrid model. Each option has its pros and cons:
    • On-premises. It offers control over the physical infrastructure but requires significant maintenance and upfront costs. 
    • Cloud-based. It provides scalability and lowers initial costs but may raise concerns about data sovereignty and security. 
    • Hybrid. It combines the benefits of both on-premises and cloud, making it suitable for organizations transitioning to the cloud.
  • Assess Compliance Requirements. Ensure that the DLP tool you choose helps you meet the regulatory requirements relevant to your industry. The tool should facilitate compliance with laws and standards regarding data protection and privacy.
  • Vendor Reputation and Support. Research potential vendors’ reputations, focusing on their stability, customer support, and the robustness of their security measures. Vendor support is crucial, as it affects the implementation phase and ongoing maintenance of the DLP system. 
  • Test and Evaluate. Before making a final decision, testing the DLP tools on your shortlist in your environment is advisable. Pilot testing will help you see how well each tool integrates with your systems and meets your expectations. 
  • Cost Consideration. Analyze the total ownership cost, including licensing, implementation, training, and maintenance costs. Opt for a tool that offers the best value for money within your budget. 
  • User Reviews and Feedback. Look at feedback from other users, especially those in similar industries. User reviews can provide insights into the real-world effectiveness of a DLP tool and highlight any potential issues or advantages you might not have considered. 

By thoroughly evaluating these aspects, organizations can select a DLP tool that meets their current data protection needs and scales and adapts to future requirements.
