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

tchncs.de is a small, individual-operated platform based in Germany that provides a curated collection of open-source software services. The website hosts and links to various federated social media instances, collaboration tools, chat platforms, blogging, development, and gaming services. It operates on a donation-funded, ad-free model, targeting users interested in privacy-respecting and decentralized technology solutions. The platform emphasizes community and open-source values, positioning itself as a niche provider in the federated software ecosystem. Technically, the website uses standard web technologies including jQuery and SVG graphics, with hosting inferred to be through INWX based on nameservers. The site is moderately optimized for performance and mobile devices, with a clear and consistent branding approach. SEO and accessibility are basic but functional. Analytics are implemented via a privacy-friendly service (Plausible Analytics), indicating a focus on minimal user tracking. From a security perspective, the site uses HTTPS (assumed from URL scheme and modern practices), but lacks explicit security headers and published security policies. No incident response or vulnerability disclosure information is available, which could be improved to enhance trust and compliance. The WHOIS data is consistent with the website's claims, showing legitimate registration without privacy protection, appropriate for an individual operator. Overall, tchncs.de presents a trustworthy and well-maintained platform for open-source and federated services, with room for improvement in security policies and privacy compliance mechanisms. Strategic recommendations include implementing security headers, publishing incident response contacts, and adding cookie consent to align with GDPR best practices.

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

5 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

  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"

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

tchncs.de operates as a niche, community-focused platform offering federated and open-source software services. Its competitive advantage lies in its ad-free, donation-funded model and curated selection of privacy-respecting tools. The business model targets privacy-conscious users and open-source enthusiasts, leveraging voluntary donations rather than commercial revenue streams. The platform's ecosystem includes multiple federated social media and collaboration instances, enhancing user engagement and retention. Growth indicators include active service offerings and community chatrooms. Partnerships appear limited to federated service instances under the same domain umbrella, reflecting a tightly controlled ecosystem. The platform's small size and individual operation suggest limited scalability but strong community trust.

Security posture

The security maturity of tchncs.de is moderate. HTTPS is presumably enforced, but the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No public security or incident response policies are published, limiting transparency and preparedness. The site does not expose sensitive data or use vulnerable libraries based on the provided content. Minimal user tracking and use of privacy-friendly analytics indicate good privacy practices. However, the lack of cookie consent mechanisms and vulnerability disclosure policies are compliance gaps. Overall, the security posture is adequate for a small community platform but would benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a cookie consent banner or mechanism to comply with GDPR and enhance user privacy transparency.
  4. Regularly audit and update third-party libraries to avoid vulnerabilities.
  5. Enhance accessibility and SEO features to improve user experience and discoverability.

Technical notes

Notes

The website employs a simple but effective technical stack with jQuery and SVG for interactive and graphical elements. Hosting is managed via INWX nameservers, indicating a stable infrastructure. Performance is moderate with preloading of key images and deferred script loading. The site is mobile-optimized and uses semantic HTML elements for structure. However, no modern frameworks or CMS are detected, which may limit scalability and ease of content management. SEO is basic with meta tags and Open Graph data present but no JSON-LD structured data. Accessibility features are minimal but present. Technical risks include lack of security headers and absence of formal CMS or framework support which could impact maintainability.
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.
