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

3 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

TELTA Citynetz GmbH holds a stable position as a regional telecommunications provider with a focus on fiber optic internet and digital TV services. Their business model revolves around providing bundled telecommunications and IT services to both private and business customers. The company leverages partnerships with technology providers like TeamViewer and smartcard services to enhance customer support and service delivery. Certifications such as ISO 27001 and ISO 50001 underline their commitment to quality and information security. The website content and structure suggest a medium-sized enterprise with a clear regional market focus and a professional approach to customer engagement and service transparency.

Security posture

The website exhibits a moderate security posture with HTTPS enforced and a cookie consent mechanism in place, reflecting GDPR compliance. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published security or incident response policies indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The company could enhance its security maturity by publishing a security policy, incident response contacts, and a security.txt file to facilitate vulnerability disclosures. Overall, the security measures are adequate for the business scale but could be strengthened to align with best practices and regulatory expectations.

Recommendations

  1. Implement and configure HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response information on the website to improve transparency and trust.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap, leveraging modern web standards including HTML5, CSS3, and JavaScript. The site is mobile responsive and optimized for accessibility and SEO, with proper meta tags and structured navigation. Performance is moderate, with compressed CSS and JS assets indicating optimization efforts. The hosting provider is not explicitly identified. The site uses a cookie consent plugin to comply with privacy regulations. Technical debt appears low, but the absence of advanced security headers and explicit performance metrics suggests room for technical enhancements to improve security and speed.
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.
