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

SIWECOS is a German-based service focused on providing website security checks and CMS security analysis primarily targeting small and medium-sized enterprises (KMU). The platform offers an online security scanner, a security seal, and support resources to help website operators identify and remediate security vulnerabilities. The website is professionally designed, bilingual (German and English), and supported by reputable partners including government and academic institutions. Technically, the site is built on Joomla CMS, hosted by Hetzner, and uses Matomo for privacy-conscious analytics. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security posture is solid with HTTPS enforced and secure forms, though some improvements are recommended such as adding security headers and cookie consent mechanisms. Overall, the domain and hosting information align with the business claims, indicating legitimacy and trustworthiness.

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

7 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. 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
  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

SIWECOS operates in the technology sector with a focus on cybersecurity services for websites and content management systems. Its business model revolves around providing automated security checks and certification seals to enhance trust for website operators and their visitors. The target market is SMEs in Germany, supported by partnerships with government agencies and industry groups. The company leverages a network of partners including hosting providers and academic institutions to strengthen its market position. The website content and structure reflect a professional and credible organization with a clear value proposition. Revenue streams likely include subscription or service fees for security scanning and certification. The partnership ecosystem enhances credibility and market reach.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and secure login and registration forms. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended best practices. There is no publicly visible security policy or incident response information, nor a security.txt file for vulnerability disclosure. The absence of a cookie consent mechanism is a compliance gap under GDPR. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of Matomo analytics indicates a privacy-conscious approach to user tracking. Overall, the security maturity is adequate for the business type but could be improved with additional security controls and transparency.

Recommendations

  1. Implement a cookie consent banner to comply with EU cookie laws and improve privacy compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish a detailed privacy policy page with explicit GDPR compliance statements and data processing details.
  4. Create and publish a security policy and incident response plan accessible to users, including a security.txt file for vulnerability reporting.
  5. Enhance contact information availability by providing official company emails and phone numbers for support and security incidents.

Technical notes

Notes

The website is built on Joomla CMS, a widely used open-source content management system, indicating a mature and supported platform. Hosting is provided by Hetzner, a reputable German hosting provider, ensuring reliable infrastructure. The site uses modern HTML5, CSS3, and JavaScript technologies with responsive design for mobile optimization. Matomo analytics is used for privacy-friendly user tracking. Performance is moderate with no major issues detected. The site structure and meta tags support good SEO. However, the absence of advanced security headers and cookie consent mechanisms indicates some technical debt in security and compliance areas. Overall, the technical implementation is solid but could benefit from modernization in security controls and privacy features.
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.
