Introduction to DLP and EDR
Definition of DLP
Imagine you are trying to keep a secret in a room full of people. Every time you speak, you risk someone overhearing. That’s what businesses face when protecting sensitive data in the digital world.
But DLP acts like a vigilant friend who keeps tabs on every word, ensuring that confidential information stays where it belongs and doesn’t accidentally slip out. Whether it’s through emails, downloads, or cloud storage, DLP keeps a watchful eye, preventing leaks before they happen.
Key Features of DLP
Data loss can happen when digital files are destroyed, corrupted, or deleted. It can have serious consequences on companies and disrupt business operations. Every good DLP solution has the following key features to prevent such issues:
- A strong DLP solution can scan and identify sensitive data across all endpoints. It makes it easier to apply the right data protection.
- DLP solutions provide real-time monitoring capabilities to track data flows and movements; they can promptly detect policy violations and suspicious activities
- Can apply content-based classification to detect patterns and context in documents, emails, and various file types. DLP solutions can block unauthorized data access and implement the right data security measures
- UEBA capabilities are included with DLP solutions; they look for red flags, allow rapid investigations, and detect account compromises.
As mentioned, DLP helps your organization protect sensitive information from being unintentionally or maliciously shared, leaked, or accessed by unauthorized users. Here are some of the key features of DLP:
- Continuously tracks data movement
- Identifies confidential information like personal identification information (PII) or intellectual property
- Automatically applies predefined policies to secure data
- Blocks unauthorized data access or transfers
Definition of EDR
EDR is a service that monitors endpoints for threats and responds to them. An endpoint is a physical device that connects to a network, such as a mobile phone, tablet, computer, or server. An EDR collects information from these endpoints and analyzes it for suspicious activity that indicates a threat. For example, changes to critical system configurations such as passwords, host files, and devices could indicate that the device has been compromised by malware or viruses.
Key Features of EDR
Effective EDR systems have some common capabilities:
- Constantly tracks endpoint activities for suspicious behavior
- Identifies known and unknown threats using advanced analytics
- Provides tools to investigate and remediate detected threats
- Gathers and stores endpoint data for forensic analysis

How DLP work?
DLP scans and classifies sensitive information, such as PII or intellectual property. Then, the organizations proceed to create policies that dictate how such data should be handled.
As already mentioned, the DLP solution monitors data in motion (such as emails, and file transfers), data at rest (such as stored files), and data in use (being accessed by users). When it detects a potential violation of these policies, such as unauthorized sharing or access, it takes action, such as blocking the transfer, alerting administrators, or logging the incident for further review.
Types of DLP solutions
In this section, let’s look at the three main types of DLP solutions.
1. Network-Based DLP
By inspecting data flows like email, web traffic, and file transfers, a network-based DLP solution monitors and protects data across the organization’s network. This type of DLP detects and blocks the unauthorized transmission of sensitive information and prevents data breaches.
2. Endpoint-Based DLP
Endpoints are susceptible to compromises in two key ways: they’re easy to physically compromise and they often connect to external networks. Endpoint-based DLP solutions protect organizations by safeguarding data stored on these devices. They monitor user activity and inspect the data on the devices. They enforce security policies, providing a critical advantage to organizations with remote or mobile workforces.
3. Cloud DLP
Cloud DLP protects sensitive data in cloud environments and applications. By observing transactions and data storage in your cloud environments, it ensures that your critical information isn’t exposed to the Internet. This capability is critical if you’re using cloud services for data storage and collaboration.
Benefits of using DLP
- Automates monitoring the flow of data inside organizations, freeing up staff to focus on core business operations
- Aids in compliance with regulations like HIPAA, GDPR, and SOX
- Provides improved visibility into how data is used
Challenges and limitations of DLP
- Legacy data can present challenges due to how it is structured (or not) and how applications use it.
- It can be difficult to balance controlling data flows and ensuring it is accessible.
How EDR Works?
EDR monitors endpoints by:
- Collecting data about changes to files, network connections, and user activity.
- Analyzing the data by applying machine learning algorithms that detect suspicious activity, such as changes to core system files, connections to dangerous systems, and unauthorized activity.
- Responding to threats by triggering alarms, recording that issue, and removing or disabling the threats.
Whenever a potential threat is detected, EDR comes with tools for investigation and remediation, allowing security teams to isolate affected devices and remove malicious files.
Benefits of using EDR
- Quickly identifies and mitigates known and unknown threats through advanced analytics and behavioral analysis
- Provides continuous oversight of endpoint activities, allowing for immediate response to suspicious behavior
- Automates responses to threats, reducing response times and minimizing potential damage
- Offers detailed logs and insights into security incidents, aiding in root cause analysis and compliance reporting
Challenges and Limitations of EDR
- EDR systems have difficulty detecting zero-day attacks that do not conform to known threat patterns
- Deploying EDR solutions can be complex and time-consuming, requiring careful planning and integration with existing security infrastructures
- The software used to collect endpoint data often consumes significant resources, making the endpoints more difficult to use
- EDR only monitors endpoints, and cannot detect threats from outside sources
