The business operates primarily in Germany and is affiliated with the University of Münster and the parent company Reedu GmbH & Co. KG. Their offerings include hardware kits like senseBox:home, senseBox:edu, and senseBox:mini, alongside software tools such as Blockly for programming and the openSenseMap data platform. The website demonstrates a strong market position within the niche of educational and citizen science IoT solutions, supported by reputable funding and partnerships. Technically, the website is built using the Jekyll static site generator, enhanced with Bootstrap for responsive design, FontAwesome icons, and privacy-focused analytics via Matomo. Hosting is supported by Amazon AWS DNS infrastructure. The site features a comprehensive cookie consent mechanism (Klaro) and is optimized for mobile devices with good SEO practices. Performance is moderate, with room for improvement in accessibility features. From a security perspective, the site enforces HTTPS and uses privacy-respecting analytics, but lacks visible security headers and published security policies or incident response contacts. No vulnerabilities or suspicious patterns were detected in the provided data. Privacy compliance is strong with GDPR-aligned policies and consent mechanisms. The absence of direct contact emails or phone numbers on the homepage is noted, with contact facilitated via a form. Overall, senseBox.de presents a professional, trustworthy, and content-rich platform with a solid business foundation and good technical implementation. Strategic improvements in security headers, incident response transparency, and accessibility could further enhance their security posture and user trust.

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

  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 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';…

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

senseBox operates in the education and technology sectors, targeting educators, students, and citizen scientists interested in environmental monitoring and IoT projects. Their business model revolves around selling modular hardware kits, providing free software tools, and fostering a community through open data platforms and educational content. Revenue streams likely include hardware sales via their shop, grants, and partnerships. The company benefits from strong partnerships with foundations, universities, and research projects, enhancing credibility and market reach. Growth indicators include active social media presence, recent product launches, and ongoing research collaborations. The partnership ecosystem is robust, involving notable organizations such as Telekom Stiftung and Hopp Foundation. The company maintains a clear focus on innovation and community engagement within its niche.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and privacy-friendly analytics (Matomo) are used alongside a clear cookie consent mechanism (Klaro), indicating compliance with GDPR. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No incident response or vulnerability disclosure policies are published, which could hinder rapid response to security events. The lack of exposed sensitive data and use of reputable hosting providers are positive indicators. Overall, the security posture is adequate for the business type but would benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Introduce a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility features to comply with standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.

Technical notes

Notes

The website is built on a modern static site generator (Jekyll) with Bootstrap for responsive design, ensuring good mobile optimization and SEO. Use of FontAwesome and Highlight.js enhances UI and code presentation. Analytics are handled by Matomo, a privacy-conscious alternative to mainstream services. Hosting is via AWS DNS infrastructure, indicating reliable uptime and scalability. Performance is moderate, with potential improvements in loading speed and accessibility. The site uses a cookie consent manager (Klaro) integrated before analytics scripts, demonstrating good privacy practices. Technical debt appears low, but the absence of security headers and limited accessibility features suggest areas for modernization and risk mitigation.
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.
