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

1 finding 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.

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

TANIX operates in a niche IoT market within the Czech Republic, focusing on LoRaWAN technology and certified sensor integration. Their business model is B2B, providing hardware integration, data visualization, and consulting services. The company leverages partnerships with network providers like České Radiokomunikace a.s. Their clear contact channels, certified product offerings, and GDPR-compliant practices indicate a customer-focused approach. The company appears small-sized, founded in 2016, with no public parent or subsidiary affiliations. Their market position is that of a specialized technology provider with a growing presence in IoT solutions. The website content and structure support their credibility and professional image.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and cookie consent mechanisms that respect user privacy. The use of Sentry for error monitoring indicates proactive incident detection. However, the absence of explicit security policies, incident response contacts, and security.txt files suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site could enhance security by implementing standard HTTP security headers and publishing formal security and incident response documentation. Overall, the security maturity is good but not comprehensive.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add standard security HTTP headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to enhance protection.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website is built on the Yii PHP framework with frontend technologies including jQuery and Bootstrap, ensuring responsive design and moderate performance. Hosting is provided via a cloud service (vshosting.cloud), with assets served from an S3-compatible storage. The site uses Google Analytics and Leady for analytics and tracking, with anonymized IP handling and user consent mechanisms. Error tracking is managed through Sentry, indicating good operational monitoring. While the site is mobile-optimized and well-structured, SEO and accessibility could be further improved. No CMS was detected, suggesting a custom or framework-based solution. Overall, the technical infrastructure is modern and stable with opportunities for enhancement in security headers and performance tuning.
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.
