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

Media Bus d.o.o is a Slovenian company established in 2004, specializing in outdoor advertising with a focus on bus advertising, vehicle wrapping, digital printing, and digital messaging services. It holds a leading market position in Slovenia as the largest provider of bus advertising. The website is built on WordPress with common plugins such as Revolution Slider and Mailchimp integration for newsletter subscriptions. The technical infrastructure is moderate in performance and mobile optimized, though it uses an outdated jQuery version which poses security risks. The security posture is basic with HTTPS enabled but lacks important security headers and uses outdated libraries. Privacy compliance is limited, with no visible cookie consent or GDPR-specific policies, although a terms of service document is available. Business credibility is strong with clear contact information, customer testimonials, and an ISO certification displayed. Overall, the website is professional and trustworthy but would benefit from security and privacy improvements.

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

10 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Media Bus operates in the media and transportation sectors, providing advertising solutions primarily targeting businesses seeking outdoor advertising in Slovenia. Their business model revolves around offering marketing communication services via mobile outdoor media such as buses and vehicles. The company leverages partnerships, such as with zaslon.si for digital messaging, and maintains a medium-sized operation with a solid market presence. Revenue streams likely include advertising contracts and printing services. The website content and testimonials indicate a focus on quality service and customer satisfaction, supporting growth and market leadership.

Security posture

The current security maturity level is basic. HTTPS is implemented, but the absence of security headers like Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. The use of an outdated jQuery version introduces potential vulnerabilities. No incident response or security policy information is publicly available, and privacy compliance mechanisms are lacking. The site does not expose sensitive data but would benefit from improved security practices and GDPR compliance measures to reduce risk and enhance trust.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions.
  2. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options.
  3. Add a cookie consent banner and update privacy policies to ensure GDPR compliance.
  4. Configure or remove unused analytics plugins to avoid unnecessary data collection.
  5. Publish a security policy and incident response contact information to improve transparency and readiness.

Technical notes

Notes

The website is built on WordPress 6.0.11 using plugins such as Revolution Slider and MonsterInsights (Google Analytics plugin). It uses jQuery 1.11.1 loaded from CDN, which is outdated and vulnerable. The site loads external resources from trusted CDNs and integrates Google Maps API and Mailchimp for newsletter subscriptions. Performance is moderate with some optimization for mobile devices. SEO is basic with meta viewport and charset tags but lacks advanced SEO markup like Open Graph or JSON-LD structured data. Accessibility features are minimal. Hosting is provided by NEOSERV.si, a Slovenian hosting provider, consistent with the domain registration. Overall, the technical stack is functional but requires modernization and security hardening.
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.
