Protecting strategic data is no longer optional—it is mandatory. With cyberattacks on the rise and regulations (GDPR, ISO 27001, NIS2 directive, etc.) imposing strict requirements, Data Loss Prevention (DLP) has become an essential component of any cybersecurity strategy.
Protect your sensitive data with Hornetsecurity
Hornetsecurity, a recognized player in European cybersecurity, offers a comprehensive DLP solution suitable for businesses of all sizes that want to protect their exchanges and ensure compliance in their communications.
What is DLP (Data Loss Prevention)?
DLP, or data loss prevention, is a technology thatprevents the leakage, deletion, or unauthorized use of sensitive data. These solutions use rules and analysis algorithms to monitor, filter, and block data flows, both within the network and to the outside world.
Concrete examples of data protected by a DLP solution:
- Personal data (name, address, social security number, etc.)
- Financial or banking information
- Customer files or confidential contracts
- Trade secrets or source codes
What is the purpose of a DLP solution?
A DLP solution enables you to:
- Prevent data leaks via email, messaging, cloud, or removable media
- Control transfers of sensitive files both inside and outside the organization
- Alert in real time in case of prohibited transmission attempts
- Ensure regulatory compliance (GDPR, HIPAA, ISO 27001, etc .)
- Ensure complete traceability of exchanges
What are the different types of DLP?
DLP solutions fall into several categories depending on the scope of protection:
1. Network DLP
Monitors and filters incoming and outgoing network traffic. For example, it blocks the sending of a file containing sensitive data to an external address.
2. DLP Endpoint
Installs on user workstations (PCs, laptops) to prevent data from being copied to USB devices, sensitive documents from being printed, or screenshots from being taken.
3. DLP Cloud
Protects data hosted in SaaS environments (Microsoft 365, Google Workspace, etc.) by blocking exfiltration or mishandling via the cloud.
Examples of effective DLP policies
A well-designed DLP policy is based on contextualized rules. Here are a few examples:
- Automatic blocking of emails containing an unencrypted IBAN number
- Mandatory encryption of attachments containing HR data
- Notify the administrator if sensitive files are shared with unauthorized domains
- Prohibition on copying classified files to an unapproved USB device

What is the difference between DLP and EDR?
DLP should not be confused with EDR (Endpoint Detection and Response):
| Criterion | DLP | EDR |
|---|---|---|
| Objective | Prevent data loss or leakage | Detect and respond to attacks on workstations |
| Target | Data (content, movement, dissemination) | Terminal behavior (malware, scripts, anomalies) |
| Mode of action | Blocking flows and alerts | Behavioral analysis and automated response |
| Tools | Hornetsecurity DLP, Microsoft DLP | SentinelOne, CrowdStrike, Fortinet EDR |
Why implement a DLP strategy now?
- Increase in accidental internal data leaks
- GDPR fines indexed to turnover
- Increased requirements under the NIS 2 Directive
- Need for traceability and auditability of exchanged data

What are the four types of DLP?
- Network (Network DLP)
- Endpoints (Endpoint DLP)
- Cloud (Cloud DLP)
- Storage DLP (on file servers or databases)
Which DLP tools are recommended?
- Hornetsecurity Email DLP (specially adapted for Microsoft 365)
- Microsoft Purview DLP
- Forcepoint DLP
- Symantec Data Loss Prevention
DLP and compliance: what are the requirements?
Standards such as the GDPR require limiting personal data leaks. A DLP solution is a key lever for demonstrating the implementation of effective technical measures, as required byArticle 32 of the GDPR.
