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

LeineGlück Online-Marketing is a German digital agency specializing in web design, online shops, SEO, SEA, and social media marketing. The company targets businesses seeking to enhance their online presence and grow their brand visibility. The website is built on WordPress using modern plugins such as Yoast SEO and Borlabs Cookie, indicating a mature digital infrastructure. The site is mobile-optimized and employs HTTPS with good SSL configuration, ensuring secure communications. However, the absence of a privacy policy and security headers suggests room for improvement in compliance and security posture. Overall, the website presents a professional image with good content quality and user experience but would benefit from enhanced privacy documentation and explicit contact information to increase trust and compliance.

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. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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';…

  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 · found on this site
  • 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 as a small digital marketing agency focused on strategy, web development, and online marketing services. Its market position is niche, serving clients in Germany and possibly beyond. The business model revolves around providing digital marketing solutions including SEO, SEA, and social media campaigns. The website's use of popular WordPress plugins and structured data indicates an understanding of SEO best practices. The lack of detailed WHOIS registrant information slightly reduces transparency but does not raise significant concerns. The agency appears to maintain a consistent brand and targets business clients looking for digital growth.

Security posture

The website enforces HTTPS with excellent SSL configuration, which is a fundamental security measure. Cookie consent is implemented via the Borlabs Cookie plugin, supporting GDPR compliance. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site lacks a published security policy or incident response contact, which limits transparency in handling security incidents. Overall, the security posture is moderate but could be strengthened by implementing recommended headers and publishing security-related policies.

Recommendations

  1. Publish a comprehensive privacy policy page detailing data processing and GDPR compliance.
  2. Implement essential security headers to protect against common web vulnerabilities.
  3. Add explicit company contact emails and phone numbers to improve trust and compliance.
  4. Create and publish terms of service and vulnerability disclosure policies.
  5. Regularly audit and update plugins and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress with Elementor page builder and uses popular plugins like Yoast SEO and Slider Revolution, indicating a modern and flexible technical stack. The presence of Borlabs Cookie plugin shows attention to cookie consent management. Performance is moderate, with some optimization via WP Rocket caching. Mobile optimization is good, and SEO meta tags and structured data are properly implemented. However, accessibility features appear basic, and no advanced security headers are present. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is solid but could benefit from enhanced security and accessibility improvements.
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.
