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

Thermoarena OÜ is a medium-sized Estonian manufacturing company specializing in high-quality thermally modified wood products such as decking, cladding, and lumber. The company emphasizes sustainability and eco-friendliness, positioning itself as a leader in the Estonian wood industry with multiple recognitions and a strong creditworthiness rating. Their target audience includes architects, designers, and environmentally conscious consumers seeking durable and natural wood alternatives. The website reflects a professional and consistent brand image with good content quality and clear navigation. Technically, the website is built on WordPress using modern libraries such as jQuery, Bootstrap, and Slick Slider. It employs HTTPS with a good SSL configuration and uses CAPTCHA to secure its contact form. However, the site lacks DNSSEC and important security headers, which are recommended for enhanced security. Performance is moderate with good mobile optimization and basic accessibility features. From a security perspective, the site demonstrates a reasonable posture with HTTPS enforcement and domain transfer protection. However, the absence of privacy and cookie policies, security headers, and incident response information indicates compliance gaps and areas for improvement. No WAF or blocking mechanisms were detected, allowing full content access. Overall, Thermoarena's website is credible and professional but would benefit from enhanced privacy compliance and security hardening to align with best practices and regulatory requirements.

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

9 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 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';…

  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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Thermoarena operates in the manufacturing sector focusing on thermally modified wood products, a niche with growing demand due to sustainability trends. The company holds a strong market position in Estonia, supported by awards and creditworthiness certifications. Their business model centers on producing and selling eco-friendly wood products to architects and builders. The website content and portfolio demonstrate a commitment to quality and customer engagement. The company leverages partnerships, such as with artmedia.ee for web services, and uses minimal but privacy-conscious analytics (Plausible). Growth indicators include recent news updates and product references. The absence of social media links suggests a focus on direct business relationships rather than broad consumer marketing.

Security posture

The website's security posture is moderate. HTTPS is properly implemented, and domain registration includes clientTransferProhibited status, reducing transfer risks. The contact form includes a CAPTCHA to mitigate spam. However, the lack of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options exposes the site to potential DNS spoofing and clickjacking risks. No explicit security or incident response policies are published, which limits transparency and preparedness. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the site is secure enough for general business use but requires enhancements to meet higher security and compliance standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance and consent mechanisms.
  4. Develop and publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update third-party libraries and plugins to mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Bootstrap, and Slick Slider for UI components. It uses Contact Form 7 for form handling with CAPTCHA integration. Image optimization is handled by EWWW Image Optimizer, improving load times. The site is mobile optimized and uses plausible.io for privacy-friendly analytics. Performance is moderate, with potential improvements in caching and CDN usage. The absence of DNSSEC and security headers indicates technical debt in security hardening. The site is hosted on a provider not explicitly identified in the HTML but uses HTTPS with a valid certificate. Overall, the technical infrastructure supports a professional online presence but can be improved for security and performance.
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.
