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

NurMarv.in is the personal website of Marvin Witt, a software engineer based in Germany specializing in web development and open source contributions. The site serves as a portfolio showcasing his projects, skills, and community involvement, particularly related to Discord datamining and software tools. The website is well designed, mobile optimized, and built using modern technologies such as Astro, React, and Fastify.

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. 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 nurmarv.in, from OffSeq Breach.

No leaked records found

Breach holds no records for nurmarv.in 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 website positions Marvin Witt as a niche individual contributor in the technology sector, focusing on software engineering and community-driven projects. His business model revolves around personal branding, open source software development, and community engagement through platforms like GitHub, Discord, and Twitter. The presence of active repositories and a dedicated project (Discord Previews) indicates a strong engagement with the developer community and Discord users. The site targets developers and tech enthusiasts interested in Discord and software tools. There is no indication of commercial sales or enterprise services, emphasizing a personal and community-oriented approach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, modern security headers, and no visible exposure of sensitive data. The use of Cloudflare for hosting and analytics adds an additional layer of security and performance optimization. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms represents a gap in formal security governance. The site does not collect sensitive user data through forms, reducing risk, but compliance with privacy regulations could be improved by adding privacy and cookie policies.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to enhance GDPR compliance and user trust.
  2. Implement a security.txt file or vulnerability disclosure page to facilitate responsible reporting of security issues.
  3. Add terms of service to clarify user rights and responsibilities.
  4. Consider adding incident response contact information to improve transparency and readiness.
  5. Regularly audit third-party dependencies and analytics tools to maintain security and privacy standards.

Technical notes

Notes

The website is built on a modern tech stack including Astro for static site generation, React for UI components, and Fastify for backend services. It leverages TypeScript, Kotlin, Java, and other languages indicating a diverse and robust development environment. Hosting appears to be via Cloudflare, providing CDN and security benefits. The site loads quickly, is mobile responsive, and includes SEO best practices such as meta tags and Open Graph data. No CMS is detected beyond Astro. The technical implementation is clean with no broken elements or errors detected. Opportunities exist to further enhance accessibility and formalize compliance documentation.
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.
