Data Loss Prevention and NIS2: how to plug DLP security gaps for NIS2 compliance

Data loss prevention (DLP) solutions, which kick in after data is stored, are insufficient for NIS2 compliance. Here’s how to plug the DLP security gap before data is stored.

Data Loss Prevention and NIS2: how to plug DLP security gaps for NIS2 compliance

Does traditional data loss prevention (DLP) software help or hinder NIS2 compliance?

Since the EU’s Network and Information Security Directive (NIS2) went live in October 2024, many CIOs and Risk & Compliance Officers are discovering their DLP security solutions offer inadequate protection for NIS2 regulations, potentially leading to non-compliance and financial penalties up to €10 million. 

As traditional DLP software only secures files AFTER they're stored, organizations are finding critical security gaps between data generation and data storage. But there is a way to plug these DLP security gaps and support NIS2 compliance without disrupting or replacing your existing DLP software. Here’s how.  

Why traditional DLP security is insufficient for NIS2 compliance

NIS2’s expanded scope 

The expanded scope of the NIS2 Directive now covers 18 sectors critical to the EU’s security, including manufacturing, aerospace and digital services. All businesses with over 50 employees or an annual turnover exceeding €10 million in these sectors must now meet tough cybersecurity standards relating to their handling of critical data - both internally and along the supply chain

In particular, both ‘essential’ and ‘important’ entities affected by NIS2 must: 

  • Ensure supply chain security. You must assess the security of your entire supply chain, including third-party vendors and contractors, and take actions to close security gaps
  • Encrypt sensitive data in transit and at rest. You must ensure sensitive files are protected both in transit and at rest, while also preventing unauthorized access.
  • Monitor security continuously. You must detect cyber incidents quickly and notify the authorities of security incidents within 24 hours.   

However, traditional DLP solutions fall short on all three measures. 

DLP shortcomings relating to NIS2 compliance

Data loss prevention solutions include a wide range of cybersecurity software, such as antivirus software and firewalls. From highlighting suspicious activity to monitoring for attacks, many DLP solutions satisfy NIS2 requirements - but only after the data has been stored. 

Since traditional DLP security kicks in at the storage level, it creates significant security blind spots between file creation and storage. This is particularly concerning for NIS2 compliance, which requires access controls and security monitoring from when data is generated. 

How Secude plugs the security gap between data generation and storage

Secude’s solutions automatically apply Microsoft Zero Trust protection and data governance to your sensitive data as soon as it’s generated. 

Built into the application layer (instead of the storage level like data loss prevention solutions), Secude’s products automatically classify, monitor, and protect files, such as PDFs and xls files of SAP data exports (HaloCORE) and CAD files (HaloCAD), in transit and at rest - no matter where you sensitive files travel along the supply chain. 

What’s more, Secude’s solutions use Microsoft sensitivity labels to prevent unauthorized access to your data (even if leaked or stolen) and provide real-time notifications and alerts for monitoring purposes.

Secude complements your existing DLP solutions

Secude and DLP are different offerings serving different parts of the security journey. Like a relay race, Secude secures your sensitive data between data generation and storage before passing the baton on to your existing DLP solutions. 

Working together, Secude and DLP therefore plug your security gaps and help you meet NIS2 requirements and keep workflows secure.
