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

OnniBus operates as a leading Finnish bus ticket sales platform, offering affordable and reliable bus travel across Finland and to international destinations such as the Baltics and Poland. The company positions itself as a well-known and cheerful brand in the Finnish transportation market, providing various ticketing options including season passes and reward programs. The website is professionally designed with good mobile optimization and clear navigation, supporting a positive user experience. Technically, the site employs modern analytics and consent management tools such as Google Analytics, Microsoft Clarity, and Cookiebot, indicating a mature digital infrastructure. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though there is room for improvement in publishing explicit security policies and incident response contacts. The absence of WHOIS data is a notable anomaly, potentially due to privacy protection or recent domain registration, but the website content and business presence support legitimacy. Overall, the site demonstrates a strong business and technical foundation with moderate risk due to incomplete WHOIS transparency.

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

4 findings 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.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: bounce02.emailabs.net.pl

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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

OnniBus holds a strong market position in Finland's transportation sector, leveraging an online ticketing business model that targets general consumers seeking cost-effective travel. The company benefits from partnerships, such as with Eckerö Line, to expand service offerings. Its revenue streams likely include ticket sales, season passes, and ancillary services. The website's content and marketing tools suggest active customer engagement and data-driven growth strategies. The use of multiple analytics and marketing platforms indicates a focus on optimizing user acquisition and retention. The company appears to be large in size with a consistent brand presence and a comprehensive service portfolio.

Security posture

The website demonstrates a good security posture with HTTPS enabled and cookie consent managed via Cookiebot, ensuring compliance with GDPR requirements. However, the lack of a dedicated security policy page and incident response contact information limits transparency and preparedness. No critical vulnerabilities or exposed sensitive data were detected in the analysis. The use of third-party scripts and analytics tools introduces some risk, which should be mitigated by regular security audits. Security headers were not explicitly identified, suggesting an area for enhancement. Overall, the security maturity is moderate to good but could benefit from formalized policies and improved header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Provide clear incident response contact information to improve transparency and readiness.
  3. Implement and enforce security headers such as Content-Security-Policy and X-Frame-Options.
  4. Regularly audit third-party scripts and libraries to identify and mitigate vulnerabilities.
  5. Monitor WHOIS data and consider transparency improvements to enhance trustworthiness.

Technical notes

Notes

The website uses a modern technology stack including Google Analytics, Microsoft Clarity, Google Tag Manager, and Cookiebot for analytics and consent management. The site is served over HTTPS with good SSL configuration, supporting secure communications. Performance is moderate with good mobile optimization and basic accessibility features. The site lacks explicit CMS identification and hosting provider details. SEO is well addressed with appropriate meta tags and Open Graph data. The technical infrastructure supports a professional and user-friendly experience but could be enhanced with additional accessibility and security features.
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.
