With NIS2 in effect across the EU, Saas companies classified as essential or important entities must prepare to meet this cybersecurity regulation. It is not just a regulatory hoop: it is a turning point in how digital services handle risk, resilience and accountability. This guide explains how SaaS companies can prepare for NIS2 compliance in six practical steps.
At PrivaLex Partners we support SaaS companies with NIS2 gap assessments, risk mapping, security policy design and incident response planning. If you also process personal data, the GDPR and best practices for implementing the GDPR complement your compliance framework well.
National transposition of NIS2 was due by October 2024; from 2025 onwards authorities can supervise and request evidence. SaaS companies serving critical sectors or exceeding employee or turnover thresholds are in the spotlight. Preparing in advance avoids surprises and sanctions.
Step 1: Check whether NIS2 applies to your SaaS
The first step is clarity. NIS2 applies to organisations that fall under the EU definition of essential or important entities. That typically includes SaaS providers operating in or supporting critical sectors such as finance, health, energy or digital infrastructure.
What to check to see if NIS2 applies to your SaaS
Before investing in measures, verify these points against the national transposition of your Member State:
- Sector: if you operate in finance, health, energy, digital infrastructure, cloud services or data management, you are likely an essential or important entity.
- Size and thresholds: more than 50 employees or €10M+ in annual turnover often bring you in scope; some countries have refined these thresholds.
- Markets: if you operate in several EU countries, check the transposition in each; requirements can differ slightly.
- Role in the chain: if you provide services to clients in critical sectors (e.g. a SaaS used by a hospital or financial institution), you may be in scope even if your sector is not explicitly listed.
- Formal assessment: a scope assessment with a specialist partner gives you a clear answer and helps prioritise next steps.
Size also matters: if your organisation exceeds employee or turnover thresholds (usually more than 50 employees or €10M+ in annual revenue), you are likely in scope. Each EU country has adopted its own transposition rules; double-check your local obligations, especially if you operate in multiple markets.
Step 2: Assign a compliance and security lead
NIS2 is big on accountability. You must formally designate someone responsible for compliance, risk management and incident reporting. That can be an internal role or an external adviser (such as PrivaLex) who can guide implementation and act as your point of contact with the authorities.
Assigning a lead ensures compliance does not become scattered or reactive but stays strategic. If you combine NIS2 with privacy, an external DPO can work with the security lead to align frameworks.
Step 3: Run a cyber risk assessment
Before making changes, know where you stand. A proper cyber risk assessment is the basis for deciding which controls to implement and in what order. Without it, you invest blindly; with it, you prioritise and can demonstrate sound judgement in an inspection.
Areas a cyber risk assessment should cover
The assessment should cover at least these areas:
- Technical infrastructure: servers, networks, cloud environments and configurations that affect security. Includes patching, segmentation and credential management.
- Core services and APIs: attack surface of your products, dependencies between services and exposure to the internet. APIs are a common vector for incidents.
- Third parties and cloud providers: what data and systems are in the hands of third parties, what contracts and security clauses you have and how you monitor their compliance.
- Past security incidents: if there have been breaches, misconfigurations or unreported incidents, the assessment should reflect them and the remedial measures taken.
- Impact on business, data and customers: listing risks is not enough; you must map how threats could affect business continuity, data integrity and customer trust. That enables prioritisation and communication of risk to the board.
You are not just listing risks: you are mapping how threats could affect business continuity, data integrity and customer trust. Cybersecurity and risk management are the foundation for the rest of your measures. An information security management system (ISMS) aligned with obtain ISO 27001 certification can help meet many NIS2 requirements.
Step 4: Put strong security measures in place
NIS2 does not dictate specific tools, but it does expect appropriate and proportionate technical and organisational controls for the risk identified. Measures must be documented, implemented and reviewed periodically. Security can no longer be siloed: it must be woven into your product, culture and codebase.
Controls NIS2 expects (technical and organisational)
Among the controls authorities typically require or expect:
- Incident response plans: procedures for detection, assessment, containment and notification; assigned roles and rehearsals (tabletops or simulations).
- Access control and multi-factor authentication (MFA): least privilege, permission reviews, MFA on critical systems and admin accounts.
- Regular staff training on cyber hygiene: phishing, passwords, secure use of devices and incident reporting. The directive requires documented training tailored to role.
- Secure-by-design development: code review or secure practices, dependency and vulnerability management, and patch lifecycle in production.
- Supply chain oversight: risk assessment of ICT suppliers, contracts with security clauses and monitoring of their compliance. NIS2 extends responsibility to processors and partners that access your systems or data.
Review and document your measures periodically so you can demonstrate them in an inspection. Authorities may ask for evidence that controls are active, not just written in a policy.
Step 5: Prepare for 24-hour incident reporting
One of the most urgent NIS2 requirements is to notify the authorities of significant cybersecurity incidents within 24 hours of becoming aware of them. SaaS companies must have internal playbooks ready: clear procedures for detecting, assessing and escalating incidents quickly. Improvising once an incident has occurred usually leads to delays, errors and higher regulatory or reputational risk.
What your 24-hour notification protocol should include
To meet the deadline and do it properly, the protocol should cover at least:
- Definition of reportable incident: clear criteria (e.g. impact on availability, data loss or leakage, impact on customers or critical services) to decide when to notify the authority. Without this, the team hesitates and hours are lost.
- Roles and responsibilities: who detects, who assesses severity, who decides to notify and who drafts and sends the notification. Include a back-up contact if the designated person is unavailable.
- Escalation procedure: steps from detection (alerts, internal reports) to decision to notify and submission to the authority. It should set internal deadlines (e.g. assessment within X hours) so the 24 hours are not spent on internal debate.
- Documentation and templates: notification template or checklist with the data authorities typically request (type of incident, systems affected, measures taken, contact). Having it ready speeds drafting in a crisis.
- Rehearsals: run simulations (tabletops) at least once a year so the team knows the flow and gaps are found (outdated contacts, unclear criteria, etc.). Authorities value that you have rehearsed and documented the response.
Everyone involved (from engineering to customer support) must know their role in a response scenario; processes must be documented, rehearsed and ready. A fast, structured response reduces impact, builds regulator trust and protects your brand.
Step 6: Commit to continuous monitoring and audit
NIS2 is not a one-off project: it requires maintaining compliance over time. You must monitor your controls, review your risk register regularly and adapt security measures to evolving threats. Authorities can request evidence at any time; keeping everything up to date avoids surprises and demonstrates maturity.
Elements of continuous monitoring and audit
Include at least these elements in your continuous monitoring approach:
- Periodic control review: verify that the controls you defined (access, MFA, incident response, training, third parties) remain active and documented. Implementing them once is not enough.
- Up-to-date risk register: the risk register should reflect changes in systems, suppliers or threats; review it at least annually or when material changes occur.
- Internal or external audits: internal audits (or supported by an external party) annually help find deviations before the authority does. Some organisations combine NIS2 with ISO 27001 and use the ISMS internal audit.
- Logs and evidence: access logs, security logs and evidence that procedures are applied (simulation minutes, training records, review reports). Automation can help keep them available and auditable, especially when supported by systems that integrate AI lead generation tools alongside broader monitoring and analysis workflows.
- Continuous improvement: act on audit or incident findings (non-conformities, lessons learned) and document improvements. It shows the system evolves and is not static.
Working with a compliance partner like PrivaLex streamlines this process, especially if you are managing multiple frameworks (e.g. ISO 27001 or SOC 2) alongside NIS2. SaaS companies that proactively align with the directive gain more than legal compliance: they gain customer trust, operational resilience and a competitive edge in markets that reward security maturity.
Mistakes that can undermine NIS2 compliance preparation
Avoiding these mistakes saves you sanctions, delays and reputation. They are the most common when SaaS companies approach NIS2 without a clear plan.
Not assigning a clear lead
Without someone designated for compliance, risk management and incidents, coordination with authorities and internal consistency suffer. NIS2 requires traceable accountability; inspections ask who is in charge of compliance and notification.
Having no 24-hour notification procedure
Meeting the deadline requires defined procedures, assigned roles and teams that know when and how to trigger them. Improvising in a real incident increases regulatory and reputational risk. Authorities can impose sanctions for late or incomplete notification.
Not documenting measures or evidence
Authorities can request policies, records and operational evidence. If your documentation is not organised and up to date, an inspection may find gaps you could have closed earlier. Documenting is not bureaucracy: it is the proof that you comply.
Assuming you are out of scope without checking
If you operate in digital or critical sectors, verify with the national transposition whether you are an essential or important entity. A scope assessment with a partner avoids surprises and helps you prioritise effort.

Frequently Asked Questions (FAQs)
How can SaaS companies prepare for NIS2 compliance in practice?
In six steps: (1) check whether NIS2 applies to your organisation (essential or important entities by sector, employee and turnover thresholds, national transposition); (2) formally assign a lead for compliance, risk management and notification; (3) run a cyber risk assessment covering infrastructure, services, third parties and impact on business and data; (4) put appropriate technical and organisational measures in place (incident response, access and MFA, training, secure development, supply chain); (5) prepare your 24-hour notification protocol with criteria, roles and rehearsals; (6) commit to continuous monitoring and audit, including risk register review and internal or external audits.
Do all SaaS companies have to comply with NIS2?
No. NIS2 applies to those that fall under the definition of essential or important entities (by sector, size or role in critical infrastructure). Many SaaS providers operating in sectors such as finance, health, energy or digital infrastructure, or exceeding certain employee or revenue thresholds, are in scope. Check your Member State’s national transposition.
What is the deadline for notifying incidents under NIS2?
NIS2 requires significant incidents to be notified to the competent authority within a very short period: in practice, within 24 hours of awareness. A full notification is often required within a longer period (e.g. 72 hours) with details on impact and measures. Each country may specify deadlines in its legislation.
Can I combine NIS2 with ISO 27001 or SOC 2?
Yes. Many SaaS companies have multiple frameworks (NIS2, ISO 27001, SOC 2, GDPR). A partner like PrivaLex can help you align controls and avoid duplicating effort. A well-designed ISMS covers much of what NIS2 requires and supports ISO 27001 certification.
What if my SaaS company is not ready for an NIS2 inspection?
Authorities can request evidence (policies, records, simulation minutes, training evidence), carry out on-site or written inspections and, in case of non-compliance, impose sanctions (up to €10 million or 2% of global turnover for essential entities; up to €7 million or 1.4% for important ones). They may also require remedial measures or treat late incident notification as a breach. Preparing in advance —scope assessment, up-to-date documentation, notification procedures and team training— reduces risk and demonstrates good faith to the regulator.
How can PrivaLex help with my SaaS company’s NIS2 compliance?
PrivaLex offers NIS2 gap assessments, risk mapping, security policy design, incident response planning, training and preparation for inspections. We support you from diagnosis to implementation and monitoring, and can integrate NIS2 with ISO 27001 or privacy compliance (GDPR) in one project.
