SaaS Data Protection: Complete Guide to Securing Cloud Application Data
Learn proven SaaS data protection strategies, from classification to DLP, that keep your cloud data secure and compliant with regulations.
NIS2 is the biggest EU cybersecurity regulation since GDPR — with major implications for SaaS. Learn what IT leaders need to know about compliance.
The Network and Information Security Directive 2 (NIS2) is the European Union's updated cybersecurity framework. It replaces the original NIS Directive from 2016 and represents the most significant expansion of EU cybersecurity regulation since GDPR.
NIS2 entered into force on January 16, 2023, and EU member states were required to transpose it into national law by October 17, 2024. Organizations in scope must now comply with comprehensive cybersecurity risk management requirements — or face penalties of up to €10 million or 2% of global annual turnover, whichever is higher.
For IT leaders, NIS2 is not just a compliance exercise. It fundamentally changes how organizations must approach cybersecurity, including how they manage, secure, and govern their SaaS environments.
NIS2 dramatically expanded the scope of EU cybersecurity regulation. The original NIS Directive applied to a few hundred organizations per member state. NIS2 applies to tens of thousands across the EU.
Organizations in these sectors with 250+ employees or €50M+ turnover:
Organizations in these sectors with 50+ employees or €10M+ turnover:
Even if your organization is not directly in scope, NIS2 has a supply chain provision (Article 21(2)(d)) that requires in-scope entities to address cybersecurity in their supply chain relationships. If you are a supplier to an essential or important entity, your customer may impose NIS2-derived security requirements on you.
This means NIS2's influence extends far beyond the directly regulated entities.
NIS2's cybersecurity risk management requirements (Article 21) include several provisions that directly affect how organizations manage their SaaS environments.
The requirement: Organizations must address cybersecurity risks in their supply chain, including "security-related aspects concerning the relationships between each entity and its direct suppliers or service providers."
SaaS implication: Every SaaS vendor is a supplier. Under NIS2, you must:
The challenge: You cannot assess what you don't know about. If your organization uses 200+ SaaS applications and IT is aware of 60, you have 140+ unassessed suppliers — a direct compliance gap. This is where shadow IT discovery becomes essential.
The requirement: Organizations must implement risk analysis policies and information system security policies, including maintaining an inventory of IT assets.
SaaS implication: SaaS applications are IT assets. NIS2 requires a comprehensive, up-to-date inventory of all IT assets — which includes every SaaS application in use, who has access, what data it processes, and what security controls are in place.
A spreadsheet updated annually does not meet this standard. The inventory must be current and comprehensive.
The requirement: Organizations must have incident detection, reporting, and response capabilities.
SaaS implication: If a SaaS vendor suffers a security incident that affects your data, you must be able to:
For shadow IT applications, detection is impossible — you don't know the application exists, so you won't learn about a breach until the damage is done. You also cannot assess impact for applications not in your asset inventory.
The requirement: Organizations must implement policies for access control and asset management, including human resources security and appropriate authentication measures.
SaaS implication: This requires:
The offboarding challenge: When an employee leaves, NIS2 requires their access to be revoked across all systems. For sanctioned applications connected to your IdP, this can be automated. For shadow IT applications, it's impossible — you don't know the accounts exist. See our SaaS offboarding checklist for a comprehensive approach.
The requirement: Organizations must have business continuity management, including backup management, disaster recovery, and crisis management.
SaaS implication: If your organization depends on a SaaS application for business-critical processes, NIS2 requires:
You cannot have business continuity plans for applications you don't know your teams depend on.
NIS2 introduces a strict multi-stage incident reporting obligation that has direct implications for SaaS management:
| Stage | Deadline | Requirement |
|---|---|---|
| Early warning | 24 hours | Notify national CSIRT/authority of significant incident |
| Incident notification | 72 hours | Provide initial assessment including severity and impact |
| Intermediate report | Upon request | Provide status updates when requested by authority |
| Final report | 1 month | Detailed description, root cause analysis, mitigation measures |
Why this matters for SaaS: A significant incident at any SaaS vendor in your environment could trigger this reporting obligation. Without a complete vendor inventory, you cannot:
The 24-hour early warning deadline is particularly challenging. If you learn about a SaaS vendor breach through media reports, you need to immediately determine whether your organization uses that vendor and what data is at risk. With no SaaS inventory, this becomes a scramble rather than a process.
Based on common SaaS management practices at mid-market companies, here are the most frequent NIS2 compliance gaps:
NIS2 requirement: Comprehensive IT asset inventory Typical reality: IT tracks 30-40% of SaaS applications
Impact: You cannot perform risk analysis, apply security controls, or report incidents for assets you don't know about. This is the foundational gap that makes all other requirements harder to meet.
NIS2 requirement: Supply chain security assessment Typical reality: Security assessments exist only for major, IT-procured vendors
Impact: The majority of SaaS vendors — especially those adopted by individual employees or departments — have never been assessed for cybersecurity posture, data processing practices, or incident response capabilities.
NIS2 requirement: Access control policies Typical reality: Employees grant OAuth permissions freely with no monitoring
Impact: Third-party applications with broad access to corporate data (email, files, calendars) represent uncontrolled access that NIS2 requires you to manage. Without OAuth governance, you have no visibility into what permissions have been granted to which applications.
NIS2 requirement: Access revocation for departing employees Typical reality: Offboarding covers IdP-connected applications only
Impact: Former employees retain access to company data through shadow IT applications. This is both a security risk and a NIS2 compliance gap — access was not properly revoked across all systems.
NIS2 requirement: Incident detection and 24-hour reporting Typical reality: No process for SaaS vendor incidents
Impact: When a SaaS vendor suffers a breach, the organization cannot quickly determine if they're affected, assess the impact, or meet the 24-hour early warning deadline.
Use this checklist to assess your organization's NIS2 readiness for SaaS environments:
NIS2 introduces significantly higher penalties than the original directive:
NIS2 Article 20 is particularly notable: it requires management bodies (boards, executives) to approve and oversee cybersecurity risk management measures. Management must also undergo cybersecurity training.
This means the CISO or IT leader cannot own NIS2 compliance alone. The board must be informed about SaaS-related cybersecurity risks, approve risk management measures, and take responsibility for compliance.
If your board doesn't know about your shadow IT problem, that's itself a compliance gap.
NIS2 compliance for SaaS environments doesn't require a multi-year transformation program. A practical approach focuses on closing the highest-impact gaps first:
NIS2 is not optional, and it's not something you can address with a checkbox exercise. For SaaS environments, the foundation of compliance is visibility — a complete, continuously updated inventory of every application, user, and data flow.
Most mid-market companies have a significant gap between their current SaaS management practices and what NIS2 requires. The good news is that closing this gap starts with a single step: discovering what's actually in your environment. See how Coax's shadow IT discovery and security features help you get NIS2-ready.
