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

6 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

    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

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

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

queo holds a strong market position as a medium-sized technology and agency service provider in Germany. Its diversified group brands allow it to serve various niches including software solutions, customer journey consulting, interactive installations, and social media education. The business model focuses on integrated digital services for SMEs and larger clients, leveraging expertise in new work culture and sustainability. The company maintains active social media channels and transparent policies, enhancing its credibility. Growth indicators include multiple subsidiaries and a workforce of over 180 employees. The partnership ecosystem is visible through linked domains of subsidiaries and group brands. Strategic observations highlight queo's emphasis on innovation, customer-centric solutions, and compliance with industry standards such as TISAX.

Security posture

queo demonstrates a moderate to good security maturity level. The website enforces HTTPS and implements a comprehensive cookie consent banner with granular user choices, supporting GDPR compliance. The mention of TISAX (a recognized automotive security standard) suggests organizational commitment to security best practices. However, the absence of visible security headers (e.g., CSP, HSTS) and lack of published incident response or vulnerability disclosure policies indicate gaps in transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security culture appears proactive but could benefit from enhanced communication of security policies and incident handling procedures to build further trust.

Recommendations

  1. Implement and publish standard security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Publish clear incident response contact information and consider establishing a vulnerability disclosure policy or security.txt file to improve transparency and community trust.
  3. Enhance accessibility compliance to ensure inclusivity and meet legal requirements.
  4. Regularly review and update third-party scripts and libraries to mitigate risks from vulnerable components.
  5. Continue to maintain and communicate certifications and compliance efforts such as TISAX to reinforce security posture and market confidence.

Technical notes

Notes

The website is built on the Neos CMS platform using the Flow PHP framework, indicating a modern and flexible infrastructure. JavaScript libraries include jQuery 3.4.1 and custom scripts for cookie management and frontend interactions. Analytics are handled via Matomo Cloud and Facebook Pixel, supporting data-driven marketing while respecting user consent. Performance is moderate with autoplay video content and responsive design elements. SEO is supported by comprehensive meta tags, Open Graph, Twitter cards, and JSON-LD structured data for breadcrumbs and website schema. Hosting details are not explicit, but custom DNS servers suggest professional hosting arrangements. Technical risks include lack of explicit security headers and potential for improvement in accessibility 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.
