Security score

39/100

Risk levelHigh

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

The website for kerstin-schleicher.de currently serves as a placeholder or customer menu page for Lind & Quittek GmbH, a small company based in Mannheim, Germany. The site content is minimal and displays a message indicating the requested domain could not be found on the server, suggesting the domain is not actively hosting business content or services. The technical infrastructure includes common JavaScript libraries and the Bulma CSS framework, but lacks a valid SSL/TLS certificate and modern HTTPS configuration, which significantly impacts security and trustworthiness. Security headers are present but insufficient without proper SSL. No privacy, cookie, or terms of service policies are found, indicating poor compliance with privacy regulations. Overall, the website's digital maturity is low, with poor content quality and minimal user engagement features.

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

    • 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

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Lind & Quittek GmbH appears to be a small service provider or business-to-business company with a customer portal or menu interface. The domain registration is consistent with the company information, but the lack of active content and domain protection measures suggests limited online presence or a transitional state. No analytics or marketing tools are detected, and no social media or phone contact information is provided beyond a general email and physical address. The company likely targets existing customers rather than new client acquisition through this domain. The partnership with quadrate.media is evident from branding and email contact, indicating a possible service or hosting relationship.

Security posture

The security posture is weak due to the absence of a valid SSL certificate and HTTPS support, despite the presence of several security headers such as Content Security Policy, X-Frame-Options, and X-XSS-Protection. The domain lacks DNSSEC and CAA records, and no domain protection locks are enabled, increasing risk of domain hijacking or spoofing. No incident response or vulnerability disclosure information is available. The site does not collect user data via forms, reducing exposure but also limiting functionality. Overall, the security maturity is low and requires urgent improvements to meet basic web security standards.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS and secure user connections.
  2. Implement DNSSEC and CAA records to enhance domain security and prevent unauthorized certificate issuance.
  3. Enable domain protection locks in WHOIS to prevent unauthorized domain transfers.
  4. Develop and publish privacy and cookie policies to comply with GDPR and other privacy regulations.
  5. Add incident response and vulnerability disclosure information to improve transparency and trust.

Technical notes

Notes

The website uses a standard set of JavaScript libraries including jQuery, Chart.js, Handlebars, Tippy.js, and Select2, styled with the Bulma CSS framework. The hosting provider is not explicitly identified but the IP address and DNS servers suggest a small or private hosting environment. Performance metrics are unavailable, indicating no active content delivery or measurement. The site is minimally mobile optimized and lacks accessibility and SEO best practices. The HTML is valid but the content is limited to a placeholder message. There is no CMS detected. The technical debt is high due to missing SSL and lack of modern security configurations.
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.
