Risk levelMedium

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

Endboss GmbH is a small creative agency specializing in urban development and cultural storytelling projects. They position themselves as partners rather than traditional service providers, focusing on collaborative and inclusive urban projects. The website reflects a niche market presence with a clear emphasis on partnership and creative urban solutions. Technically, the site is built on a modern SvelteKit framework, delivering a good user experience with mobile optimization and modular JavaScript assets. Security posture is solid with HTTPS enforced, but lacks some security headers and cookie consent mechanisms. Privacy compliance is basic but present with a privacy policy and terms of service. Overall, the site is professional and trustworthy, though it could improve transparency by adding contact details and enhancing security headers.

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

8 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

  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

      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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

The company targets clients interested in urban and cultural development projects, leveraging a partnership business model. Their market position is niche, focusing on creative urban storytelling and development. The absence of visible contact details may limit direct client engagement but aligns with a boutique agency approach. The website content and branding are consistent, supporting a professional image. No evident advertising or analytics tools suggest a privacy-conscious approach. The company appears stable with a founding year of 2010, but domain age is unknown due to privacy-protected WHOIS data.

Security posture

The website enforces HTTPS, ensuring encrypted communication. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No visible vulnerabilities or exposed sensitive data were found. The absence of a cookie consent mechanism and incident response contact information indicates room for improvement in compliance and readiness. Overall, the security posture is moderate, suitable for a small agency but requiring enhancements to meet higher standards.

Recommendations

  1. Implement standard security headers including CSP, HSTS, and X-Frame-Options to improve security posture.
  2. Add a cookie consent banner and detailed cookie policy to enhance privacy compliance.
  3. Publish clear contact information including emails and phone numbers for better business credibility and incident response.
  4. Develop and publish a dedicated security policy and incident response page to improve transparency and readiness.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine visibility.

Technical notes

Notes

The website uses the SvelteKit framework, leveraging modern JavaScript modules and CSS assets for a responsive and performant user experience. The site is mobile-optimized with good navigation clarity. No CMS or hosting provider information is directly detectable. Performance is moderate with efficient image usage and preloading scripts. The absence of analytics or tracking scripts indicates minimal data collection. Technical debt appears low, but improvements in accessibility and SEO could be made. No critical technical risks were identified.
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.
