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

Nettiauto.com is a Finnish online marketplace specializing in new and used vehicles, positioning itself as the largest and most popular vehicle trading platform in Finland. The website offers a broad selection of over 90,000 vehicles, targeting Finnish consumers interested in buying or selling cars. The business model revolves around providing a digital platform for vehicle listings and dealer services. Technically, the site employs modern web technologies including JavaScript, Google Tag Manager for analytics, and Adnami for advertising. The site is well-optimized for mobile devices and accessibility, with good SEO practices evident from meta tags and structured content. Security-wise, the site uses HTTPS but lacks visible security headers and explicit privacy or cookie policies, which are areas for improvement. The WHOIS data for the domain is missing, which raises concerns about domain registration transparency, although the site itself appears legitimate and professionally maintained. Overall, Nettiauto.com presents a solid digital presence with room for enhancing security and privacy compliance.

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. 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. GDPR outside view

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

    • 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

    • High

      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
  • 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

Nettiauto.com holds a strong market position as Finland's leading vehicle marketplace, serving a large audience of vehicle buyers and sellers. Its competitive advantage lies in its extensive vehicle inventory and user-friendly platform. The business generates revenue likely through dealer listings and advertising partnerships. The target customer segment is primarily Finnish individuals and dealers interested in automotive transactions. The platform integrates advertising networks and tracking tools to support monetization and marketing efforts. Strategic observations suggest the company could benefit from improving transparency in domain registration and enhancing compliance with privacy regulations to strengthen trust and regulatory adherence.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection indicates potential vulnerabilities to common web attacks. No exposed sensitive data or vulnerable libraries were detected in the provided content. The lack of published security policies or incident response contacts suggests limited transparency in security governance. To improve, the company should implement comprehensive security headers, publish privacy and security policies, and establish clear incident response channels. These steps will enhance the site's security maturity and compliance with data protection standards.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms to comply with GDPR.
  3. Make WHOIS domain registration information transparent and up to date to improve trustworthiness.
  4. Establish and publicize incident response procedures and security contact channels.
  5. Regularly audit third-party scripts and advertising integrations for security and privacy compliance.

Key observations

  1. Website content is fully accessible and not blocked by WAF or security mechanisms.
  2. WHOIS data is missing or unavailable, which is unusual for a .com domain.
  3. No explicit privacy, cookie, or terms of service policies found in the HTML content.
  4. No contact emails or phone numbers explicitly found in the provided HTML snippet.
  5. Website uses Google Tag Manager and Adnami ad scripts.
  6. Website is in Finnish language targeting Finnish vehicle buyers and sellers.
  7. No adult or NSFW content detected.
  8. Website appears professionally designed with good mobile optimization and accessibility.
Technical notes

Notes

The website uses a modern front-end stack with JavaScript and CSS, supported by Google Tag Manager for analytics and Adnami for advertising. The site is mobile-optimized and accessible, with good SEO metadata and Open Graph tags enhancing social sharing. No CMS or hosting provider details were identified from the content. Performance appears moderate, with asynchronous loading of scripts. Technical debt is minimal based on the provided snippet, but the absence of security headers and privacy compliance features indicates areas for modernization. Enhancing security configurations and privacy transparency will reduce technical risks and improve operational resilience.
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.
