NIS2 penetration testing

NIS2 Penetration Testing Services

Test applications, APIs, cloud, networks, and identity systems supporting essential or important services. Get validated findings, remediation guidance, and clear evidence for your NIS2 programme.

NIS 2

Test the systems behind essential services

Validate realistic attack paths across the applications, infrastructure, identities, and supplier connections that matter most to service continuity.

Article 21 support

Assess whether technical measures work

Use penetration testing to support effectiveness assessment, secure development, vulnerability handling, and access-control decisions under Article 21.

Risk-based scope

Follow critical services across your environment

Scope web applications, APIs, cloud, networks, identity systems, and authorized supplier integrations according to exposure, change, and business impact.

Remediation evidence

Track findings through remediation

Give engineering, risk, and management teams a clear record of scope, findings, owners, fixes, and available validation evidence.

Where penetration testing supports Article 21

Penetration testing can support selected cybersecurity risk-management measures. It does not establish NIS2 compliance or replace governance, incident reporting, continuity, training, or national legal requirements.

How Blaze helps support it

(a)

Risk analysis and information system security policies

Identifies exploitable weaknesses in in-scope systems to inform risk analysis and treatment decisions.

(b)

Incident handling

Reveals attack paths and control gaps that can inform detection, containment, and response planning.

(d)

Supply chain security

Tests authorized supplier integrations and connected third-party systems included in scope.

(e)

Security in acquisition, development and maintenance, incl. vulnerability handling

Tests applications, APIs, and infrastructure and provides findings to support vulnerability handling.

(f)

Policies to assess the effectiveness of measures

Provides independent technical evidence that can inform assessments of whether selected security measures are effective.

(g)

Basic cyber hygiene and access control

Tests authentication, authorization, privilege boundaries, and access paths to sensitive systems.

Clear evidence for security and management teams

A NIS2 pentest should help engineers reduce risk and give decision-makers a clear record of what was tested.

Chart Donut

Remediation workspace

Track findings, owners, fixes, and available validation evidence in one place.

Seal Check

Shareable reporting

Share scope, methodology, findings, and remediation status with security, risk, management, audit, and oversight teams.

Lock Simple

CREST-accredited provider

Work with a named testing team, reviewed findings, and direct access throughout the engagement.

Stack

Reusable technical evidence

Use relevant findings in other assurance work where scope and requirements align.

Lightning

Fix validation

Confirm whether agreed fixes address the original finding when validation is included.

Reuse relevant findings

Some findings may support other assurance work when scope and requirements align. Each framework still has its own legal or assessment obligations.

01

ISO 27001

Use relevant findings in ISO 27001 risk, vulnerability-management, and control-improvement work.

02

DORA

Support digital operational resilience work for financial entities where scope and requirements overlap.

03

GDPR

Use relevant findings to support security-of-processing decisions for systems handling personal data.

Frequently asked questions

The directive does not prescribe penetration testing by name for every covered entity. Article 21 requires appropriate and proportionate risk-management measures, including effectiveness assessment and vulnerability handling; testing requirements can also depend on national and sector-specific rules.
NIS2 sets no universal pentest interval. Choose a risk-based cadence around criticality, exposure, major changes, serious incidents, and applicable national or sector guidance, then validate important fixes when retesting is included.
Testing can support effectiveness assessment, secure development and maintenance, vulnerability handling, access control, supply-chain interfaces, and risk analysis. It does not replace governance, continuity, incident reporting, training, or other organizational measures.
NIS2 covers medium and large organizations across defined essential and important sectors, with exceptions and special rules. Exact scope and classification depend on the directive, Member State law, sector, size, and services provided.
NIS2 applies broadly across essential and important sectors. DORA is the financial-sector framework for digital operational resilience. Organizations should confirm which regime and national rules apply rather than treating their requirements as interchangeable.
Prioritize systems supporting essential or important services: applications, APIs, cloud, networks, identity, exposed infrastructure, and authorized supplier connections. Final scope should reflect risk, business impact, architecture, and operational constraints.
Yes. Clear scope, validated findings, remediation ownership, and available retest evidence can support management oversight and risk decisions. They do not replace the management body’s approval and supervision responsibilities.
