Risk levelMedium

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

Kolle.dev is a small digital collaboration service based in Germany, focusing on supporting digital projects through project management, design, programming, and long-term support. The website presents a professional and clean design using modern technologies such as Nuxt.js and Tailwind CSS, indicating a good level of digital maturity. The site is fast, mobile-optimized, and provides clear information about its services and partner projects. Security posture is adequate with HTTPS enabled and no visible vulnerabilities, but lacks security headers and formal privacy or cookie policies, which are important for compliance and trust. Overall, the risk is moderate with recommendations to improve privacy compliance and security headers to enhance trust and regulatory adherence.

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. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention kolle.dev, from OffSeq Breach.

No leaked records found

Breach holds no records for kolle.dev right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates in the technology sector, targeting organizations and teams needing digital project support. Its business model revolves around collaborative project execution and networked expertise. The website links to several partner projects, indicating an ecosystem approach. The company appears small and focused on niche digital services without evident parent or subsidiary companies. The lack of detailed business registration or physical address limits full business credibility but the domain and WHOIS data are consistent and legitimate.

Security posture

Security maturity is moderate. HTTPS is enforced, and no sensitive data is exposed. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is provided, which could hinder rapid response to security events. Privacy compliance is weak due to missing privacy and cookie policies. The minimal tracking via Umami suggests a privacy-conscious approach but formal policies are needed to meet GDPR requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Publish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Provide additional contact information such as phone number or physical address to enhance business credibility.
  5. Enhance accessibility features to improve inclusivity and SEO.

Technical notes

Notes

The website uses a modern frontend stack with Nuxt.js (Vue.js framework) and Tailwind CSS for styling, ensuring responsive and performant user experience. The use of a canvas element for visual effects adds interactivity. The site is served over HTTPS with fast loading times and mobile optimization. No CMS or third-party hosting provider is explicitly detected, suggesting self-hosting or VPS use. SEO is basic with meta description present but no Open Graph or structured data found. Accessibility is basic and could be improved.
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.
