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

Marktplatz Design und Software GmbH is a well-established German digital agency founded in 1999, specializing in innovative web and app development solutions. The company serves a diverse clientele including medium-sized businesses, institutions, and municipalities, offering a broad range of services from website creation and app development to corporate design and online marketing. Their portfolio includes proprietary digital products such as BIWAPP and KatS-Plan, positioning them as both a service provider and product innovator in the technology sector. Technically, the website leverages modern web technologies including Webflow CMS, Google reCAPTCHA for form security, Matomo for analytics, and GSAP for animations, indicating a mature digital infrastructure. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a high level of digital maturity. Security measures include HTTPS enforcement and GDPR-compliant cookie consent mechanisms, although explicit HTTP security headers are not detected. From a security perspective, the site demonstrates good practices with secure forms and privacy compliance, but lacks a published security policy or incident response contact, which could enhance trust and preparedness. The absence of WHOIS data limits domain registration trust verification, but the professional presentation and detailed business information mitigate concerns. Overall, the website presents a professional, trustworthy, and user-friendly digital presence with strong business credibility. Strategic recommendations include enhancing security headers, publishing a security policy, and improving WHOIS transparency to further strengthen 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

4 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.

    • 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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.

Business context

Business profile

Marktplatz GmbH holds a strong market position as a medium-sized digital agency with over 25 years of experience, serving government entities and private sector clients. Their competitive advantage lies in combining agency services with proprietary digital products, enabling diversified revenue streams. The company targets medium-sized businesses, municipalities, and institutions, emphasizing sustainable and innovative digital solutions. Partnerships with reputable clients such as the State of Niedersachsen and the German Football Association enhance their credibility. Growth indicators include continuous product development and a comprehensive service portfolio. The company culture promotes transparency, agile workflows, and employee well-being, supporting long-term operational stability.

Security posture

The website exhibits a solid security posture with HTTPS enforced and Google reCAPTCHA protecting user input forms, reducing spam and abuse risks. Cookie consent mechanisms comply with GDPR, providing users control over data collection. However, the absence of explicit HTTP security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency and readiness for security incidents. Overall, the security maturity is good but could be enhanced by adopting additional best practices and formal policies.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to harden the website against common attacks.
  2. Publish a clear security policy and provide an incident response contact email to improve transparency and preparedness.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Improve WHOIS data transparency by ensuring accurate and complete domain registration information is publicly available.

Technical notes

Notes

The website is built on the Webflow CMS platform, utilizing modern JavaScript libraries such as GSAP for animations and jQuery for DOM manipulation. Google reCAPTCHA is integrated for bot protection on forms, and Matomo analytics is used for visitor tracking, indicating a preference for privacy-conscious analytics. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with CDN usage for static assets. The technical stack is modern and well-maintained, though the lack of detected HTTP security headers suggests room for technical security enhancements. Overall, the infrastructure supports a professional and scalable digital presence.
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.
