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

7 findings rated critical or high. Fix these first.

  1. 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: 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)

      • 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

  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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Business profile

BBA holds a stable position as a local public transport provider in Aarau, focusing on bus transit services. Their business model centers on providing scheduled bus services, ticket sales, and customer engagement. The company targets local residents, commuters, and visitors requiring reliable transportation. The website content and social media presence support customer engagement and service transparency. While no direct revenue streams are visible, the operational scale and service offerings suggest public or municipal funding and fare-based income. The company maintains partnerships with technology providers such as hausformat.com for hosting and analytics. Growth indicators include modernization of ticketing systems and active communication of service updates. Strategic observations highlight a focus on accessibility, customer service, and digital modernization.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. The use of a reputable CMS (TYPO3) and modern JavaScript libraries reduces common vulnerabilities. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options is a gap. No incident response or security policy is published, limiting transparency and preparedness communication. Privacy compliance is partial, with a privacy policy present but lacking a cookie consent mechanism. No vulnerability disclosure or security.txt file is found. Overall, the security posture is adequate for a public service website but could be improved with enhanced headers, formal policies, and user consent mechanisms.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Add a visible cookie consent banner or mechanism to comply fully with GDPR and enhance user privacy transparency.
  3. Publish a formal security policy and incident response contact information to improve trust and preparedness.
  4. Consider establishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Regularly audit third-party scripts and analytics tools to ensure no privacy or security risks are introduced.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and secure content management system, supplemented by modern JavaScript libraries such as jQuery, Owl Carousel, Fancybox, and Swiper.js for UI enhancements. Analytics are handled via Matomo and Google Tag Manager, indicating a balanced approach to data collection and privacy. The site is mobile-optimized with responsive images and layouts. Performance is moderate, with deferred loading of scripts and compressed assets. However, some technical improvements could be made in accessibility and SEO, such as adding ARIA roles and more descriptive meta tags. The hosting provider appears to be hausformat.com, which also hosts analytics, suggesting a consolidated infrastructure. Overall, the technical implementation is solid with room for modernization in security headers and privacy controls.
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.
