0–100, higher is better. How it is calculated

Mailmeisters is a Dutch-based collective of email marketing specialists providing consultancy and campaign management services. The website positions itself as a niche service provider in the email marketing domain, targeting businesses seeking expert marketing solutions. The digital infrastructure is built on WordPress with Elementor, incorporating modern tools such as Google Tag Manager and WPRocket for performance optimization. The site demonstrates good mobile optimization and SEO practices but lacks comprehensive privacy and security policy disclosures. Security posture is adequate with HTTPS enforced and cookie consent implemented, though security headers and incident response details are absent. Overall, the website is professional and trustworthy with room for improvement in compliance and security transparency.

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

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  2. 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';…

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

Mailmeisters operates in the technology sector focusing on email marketing services. Its business model revolves around providing specialized marketing expertise to clients, likely small to medium enterprises. The website content and design reflect a consistent brand identity with a clear target audience. The absence of direct contact details suggests a preference for initial contact via web forms. Integration with marketing tools like Google Tag Manager indicates a data-driven approach. No partnerships or subsidiaries are evident from the data. The company appears to maintain a focused market position with potential growth opportunities through enhanced digital presence and compliance.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms, indicating baseline security awareness. However, the lack of security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. No explicit security policies or incident response contacts are provided, which may hinder rapid response to security incidents. The use of third-party scripts requires ongoing monitoring to prevent vulnerabilities. No vulnerabilities or exposed sensitive data were detected in the analysis. Compliance with GDPR is partial due to missing privacy policy documentation. Enhancing security transparency and implementing recommended headers would strengthen the security posture.

Recommendations

  1. Implement comprehensive privacy and terms of service pages to improve compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a security policy and incident response contact information to enhance transparency and readiness.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Improve accessibility features to broaden user inclusivity and meet standards.

Technical notes

Notes

The website is built on WordPress CMS using the Elementor page builder, supported by performance optimization via WPRocket. Google Tag Manager is integrated for analytics and marketing tracking. Fonts are custom-loaded with preloading for performance. The site demonstrates moderate loading speed and good mobile responsiveness. SEO is enhanced through Rank Math plugin usage. However, no hosting provider information was detected. The technical stack is modern but could benefit from enhanced security configurations and accessibility improvements. The site structure and metadata are well-formed, supporting good search engine visibility.
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.
