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

The website welton.de represents Sebastian Welton, a seasoned systems consultant with over 35 years of experience in cross-platform systems programming and project management, particularly in IBM mainframe and related technologies. The site targets businesses and professionals seeking expert consulting services in legacy and modern IT environments. The business model is consulting-focused, with a niche market position emphasizing deep technical expertise. Technically, the website is built on WordPress using the Twenty Seventeen theme, leveraging standard web technologies such as jQuery and Google Fonts. The site is accessible, mobile-optimized, and presents content in both English and German, reflecting its German origin. However, hosting provider details are not explicitly identified, and performance is moderate. From a security perspective, the site uses HTTPS, but lacks important security headers and policies such as privacy, cookie, and terms of service. No incident response or vulnerability disclosure information is provided. No analytics or tracking scripts are detected, indicating minimal user tracking. The security posture is adequate but could be improved with standard best practices. Overall, the website is professional and credible but lacks formal privacy and security documentation. The risk level is moderate, with recommendations to enhance security headers, add privacy and cookie policies, and provide incident response contacts to improve compliance and trust.

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

9 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Sebastian Welton operates as an independent consultant specializing in systems programming and IT project implementation across multiple platforms, with a strong focus on IBM mainframe technologies. The business targets a specialized audience requiring expert technical consulting. The website content and structure suggest a small-scale, expert-driven consulting practice without evident commercial sales or e-commerce functions. The bilingual content broadens reach within German and English-speaking markets. No partnerships or subsidiaries are indicated. The absence of social media and marketing tools suggests a low-profile, reputation-based business model relying on direct contacts and expertise.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, it lacks critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are important for mitigating common web vulnerabilities. No privacy or cookie policies are present, which is a compliance gap under GDPR. The absence of incident response contacts and vulnerability disclosure mechanisms limits the site's readiness to handle security incidents. No evidence of vulnerable libraries or exposed sensitive data was found. Overall, the security maturity is moderate but requires improvements to align with best practices and regulatory requirements.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users about data handling practices.
  3. Add terms of service and clearly defined incident response contact information to improve transparency and readiness.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities from outdated software.
  5. Consider integrating minimal analytics with privacy-respecting configurations to gain insights while maintaining user trust.

Technical notes

Notes

The website is built on a stable and widely used CMS platform, WordPress 5.6.14, with the default Twenty Seventeen theme customized for branding. It uses jQuery 3.5.1 and Google Fonts for styling and interactivity. The site is responsive and mobile-friendly, with good navigation clarity. Performance is moderate, likely due to standard hosting and no advanced optimization techniques detected. No CDN or advanced caching mechanisms are evident. The site lacks advanced SEO optimizations and accessibility features beyond basic screen reader support. Technical debt appears low but modernization opportunities exist, especially in security and compliance implementations.
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.
