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

Thomas-Krenn.AG is a European-based technology company specializing in customized server and IT system solutions for professional applications. The company offers a wide range of products including rack servers, tower systems, workstations, industrial systems, and storage solutions, targeting businesses and IT professionals. Their business model focuses on B2B e-commerce combined with personalized consulting and support services, positioning them as a trusted provider in the server hardware market. The website reflects a mature digital presence with comprehensive product information, clear navigation, and professional design. Technically, the website employs modern web technologies such as Handlebars.js for templating, SwiperJS for sliders, and Salesforce Live Agent for live chat support. The site is mobile-optimized, accessible, and SEO-friendly, indicating a well-maintained technical infrastructure. Security measures include HTTPS enforcement, CSRF tokens in forms, and inferred security headers, contributing to a strong security posture. However, explicit security policies and incident response information are not published, representing an area for improvement. The WHOIS data is notably absent or inaccessible, which raises some concerns about domain registration transparency. Despite this, the website's professional content, detailed legal pages, and active customer support channels suggest legitimate business operations. No WAF or blocking mechanisms were detected, and the site is fully accessible. Overall, Thomas-Krenn.AG demonstrates a solid business and technical foundation with good security practices. Strategic recommendations include publishing explicit security and incident response policies, implementing a vulnerability disclosure program, and improving domain registration transparency to enhance trust and compliance.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

Thomas-Krenn.AG operates in the technology sector, focusing on customizable server hardware and IT infrastructure solutions. Their competitive advantage lies in offering tailored server configurations combined with personal consulting and support, catering to a medium-sized business market primarily in Germany and Europe. The company leverages a direct B2B e-commerce platform supplemented by extensive product information and customer service. Growth indicators include a broad product portfolio and active customer engagement channels. Partnerships with technology providers and use of Salesforce Live Agent for customer interaction reflect a mature operational ecosystem. The absence of public domain registration details suggests a need for improved transparency to support business credibility.

Security posture

The website exhibits a good security maturity level with HTTPS enforced, CSRF protection in forms, and inferred security headers. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of published security policies, incident response plans, and vulnerability disclosure mechanisms indicates gaps in formal security governance and transparency. Compliance with GDPR is supported by comprehensive privacy and cookie policies. Incident response readiness and security culture indicators are not publicly visible, suggesting potential areas for enhancement. Overall, the security posture is solid but could benefit from increased transparency and formal documentation.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure program including a security.txt file.
  3. Enhance domain registration transparency by ensuring WHOIS data is complete and accessible.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Increase visible trust signals such as certifications and security badges to reinforce customer confidence.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform utilizing modern JavaScript libraries such as Handlebars.js and SwiperJS for dynamic content rendering and user interface components. Integration with Salesforce Live Agent provides real-time customer support capabilities. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with potential for optimization in loading times. SEO best practices are followed with proper meta tags and structured navigation. Technical risks are minimal but include reliance on third-party scripts and incomplete WHOIS data which could impact domain trustworthiness.
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.
