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

Graz-Köflacher Bahn und Busbetrieb GmbH (GKB) is a regional transportation company based in Austria, providing rail and bus services primarily in the West Styria region. The company has a long history dating back to 1935 and focuses on sustainable mobility solutions including electrification of rail lines and regional bus services. Their website serves as an information portal for passengers, offering schedules, fare information, and service updates. The company maintains an active social media presence and provides comprehensive privacy and cookie policies in compliance with GDPR. Technically, the website is built on Joomla CMS with common web technologies such as jQuery and Bootstrap, but lacks a valid SSL certificate, which is a critical security shortfall. The absence of HTTPS and modern TLS protocols exposes users to potential risks. Despite this, the site is well-structured, mobile-optimized, and provides clear contact information. Overall, the business is credible and well-established, but the website's security posture requires urgent improvement to protect user data and maintain 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

12 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. Network security

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

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • 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
    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 · found on this site
  • 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

GKB holds a strong market position as a regional public transport provider in Austria, with a diversified service portfolio including rail, bus, and micro-mobility solutions. Their business model is focused on public service with a medium-sized operational scale. The company leverages partnerships with regional transport networks and maintains a digital presence to engage customers. Growth is indicated by ongoing infrastructure projects such as electrification and service expansions. The website reflects a professional brand image consistent with their sector. However, the lack of advanced security measures on their digital platform could impact customer trust and regulatory compliance. Strategic partnerships with regional ticketing and mobility providers enhance their service offering.

Security posture

The website's security posture is currently weak due to the absence of a valid SSL certificate and lack of HTTPS support, which is a critical vulnerability. No modern TLS protocols are enabled, and important security headers like HSTS are missing. While some best practices such as HttpOnly and Secure cookie flags are implemented, the overall SSL/TLS configuration is inadequate. There is no evidence of incident response contact channels or vulnerability disclosure policies. Privacy compliance is well addressed through comprehensive policies and cookie consent mechanisms. Immediate remediation of SSL/TLS issues is essential to protect user data and comply with security standards.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable outdated protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Establish and publish an incident response contact email (e.g., security@ or abuse@) and vulnerability disclosure policy.
  5. Regularly audit and update all server software and third-party libraries to mitigate vulnerabilities.

Technical notes

Notes

The website is hosted on an Apache server and uses Joomla CMS version 4.5.3 with K2 content extension. It incorporates common frontend libraries such as jQuery, Bootstrap, Font Awesome, and Google Fonts. The site uses Revolution Slider for visual content and integrates social media widgets including Facebook SDK and Elfsight Instagram plugin. DNS records indicate hosting with A1.net and email services via Outlook protection. Performance data is missing, but the site appears moderately optimized for mobile devices. The lack of SSL/TLS is a significant technical debt. The site uses cache-control headers to prevent caching, which may impact performance. Overall, the technical infrastructure is standard but requires modernization in security and performance monitoring.
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.
