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

      SSL Certificate Expires Soon

      SSL certificate expires in 26 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Maileon operates primarily in the technology sector, focusing on SaaS marketing automation solutions. Its business model targets marketing professionals across industries, offering scalable and flexible tools to enhance conversion and revenue. The company maintains a strong partnership ecosystem and international presence with multiple language sites and offices. Competitive advantages include a robust feature set, integration capabilities, and a long-standing market presence. Revenue streams likely derive from subscription-based services and enterprise contracts. The company emphasizes data-driven marketing and personalized customer engagement.

Security posture

The website enforces HTTPS and employs a GDPR-compliant cookie consent mechanism, indicating awareness of privacy regulations. However, no explicit security headers were detected in the HTML content, and there is no visible security policy or incident response information. No vulnerabilities or exposed sensitive data were found in the content. The use of third-party scripts like Google Tag Manager and Lead Forensics is managed with consent. The absence of a security.txt or vulnerability disclosure page suggests room for improvement in transparency and incident readiness.

Recommendations

  1. Publish a clear and accessible privacy policy and terms of service pages in all language versions.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a security policy or incident response page including contact channels for security issues.
  4. Consider publishing a security.txt file to facilitate vulnerability disclosures.
  5. Regularly audit third-party scripts and dependencies for security vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress CMS platform with up-to-date plugins including Yoast SEO Premium for SEO optimization. It uses jQuery, Swiper.js for sliders, and Lottie Player for animations, indicating a rich interactive experience. Hosting is provided by Hetzner Online GmbH, a reputable German provider. Performance appears optimized with responsive design and image optimization. The site uses Google Tag Manager and Lead Forensics for analytics and tracking, integrated with a GDPR-compliant cookie consent solution. Technical debt appears low, but security header implementation and explicit privacy documentation could be 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.
