NIS2 Art. 21(2)

  1. (a) Risk analysis and security policies: Not visible from outside

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

5 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

OnAudience holds a competitive position in the data provider sector, leveraging partnerships with leading platforms and agencies to deliver scalable and privacy-compliant data solutions. Their business model centers on providing verified and enriched data sets to marketers, agencies, and data science teams, enabling personalized and effective digital campaigns. The company demonstrates growth through strategic collaborations and a broad market footprint. Their ecosystem includes partnerships with technology and advertising leaders, enhancing their market credibility and reach.

Security posture

The website employs HTTPS with strong SSL configuration and integrates Google reCAPTCHA Enterprise for bot mitigation, reflecting a solid baseline security posture. Cookie consent management is implemented with granular user controls aligned with GDPR and CCPA standards. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not visibly declared, and no public security or incident response policies are found. There is no vulnerability disclosure or security.txt file, indicating room for improvement in transparency and incident readiness.

Recommendations

  1. Implement and explicitly declare comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a dedicated security policy and provide clear incident response contact channels to improve transparency and trust.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting and demonstrate security maturity.
  4. Enhance visibility of data protection officer contact information to comply fully with GDPR transparency requirements.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are introduced.

Technical notes

Notes

The website is built on WordPress CMS, utilizing modern JavaScript libraries such as Swiper.js for UI components and Google Tag Manager for analytics and marketing tags. SEO is well-optimized with Yoast SEO plugin, and the site is mobile responsive with good accessibility features. Hosting is managed via DNS servers at home.pl, indicating a European hosting provider. Performance is moderate with video content and multiple scripts, but overall user experience is smooth and professional. Technical debt appears low, though explicit security headers and advanced performance optimizations could be further enhanced.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
