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

4 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 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. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

The company operates in the technology sector, focusing on email marketing solutions for the Mittelstand and enterprise segments. Its business model is SaaS-based, providing scalable email marketing automation and multi-location account management. The website's structured data and social media presence indicate a consistent branding strategy and active engagement with customers. The absence of terms of service and security policies suggests areas for improvement in formalizing compliance and security transparency. The marketing ecosystem includes partnerships with major ad networks like Meta and Google, leveraging retargeting and analytics to optimize customer acquisition and retention.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms that comply with GDPR. However, the lack of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the defense-in-depth posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or incident response contact limits transparency and readiness for security incidents. Overall, the security maturity is moderate to good but could benefit from enhanced header configurations and formal security disclosures.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish a dedicated security policy and provide clear incident response contact channels to improve transparency and trust.
  3. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Add a terms of service page to clarify user agreements and legal protections.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities or outdated components are present.

Technical notes

Notes

The website is powered by WordPress 6.8.3 with the Avada theme, a widely used and supported CMS and theme combination. It uses modern web technologies including asynchronous loading of scripts, Adobe Typekit fonts, and clipboard.js for enhanced user experience. Analytics are handled via Matomo and Google Analytics, integrated through Google Tag Manager. Cookiebot manages cookie consent with granular user controls. Performance is moderate with caching and optimization plugins implied by autoptimize CSS usage. Mobile optimization is good, though accessibility features are basic. Hosting provider details are not explicitly found in the content. Overall, the technical stack is modern and well-maintained with opportunities for further optimization and security hardening.
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.
