Risk levelHigh

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

Glassense is a medium-sized Estonian company specializing in manufacturing and supplying energy-efficient glass solutions for buildings across Europe. Founded in 2022, the company operates three production sites and offers a comprehensive range of products including facade glass, window glass, interior glass, and related services such as heat treatment, laminating, digital printing, and insulated glass units. The company positions itself as a market leader in glass expertise for energy-efficient buildings, targeting construction professionals and sustainability-focused organizations. The website reflects a professional and consistent brand image with clear business information and contact details. Technically, the site is built on WordPress with modern plugins and SEO tools, delivering moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled and domain transfer protection, but lacks DNSSEC and security headers. Privacy compliance is weak due to missing privacy and cookie policies. Analytics and tracking tools like Google Analytics and Facebook Pixel are used without visible consent mechanisms. Overall, the site is trustworthy and professional but would benefit from enhanced security and privacy compliance measures.

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

Glassense operates in the energy sector focusing on energy-efficient building materials, specifically glass solutions. Its business model revolves around manufacturing and delivering specialized glass products to customers across Europe, leveraging sustainability trends and regulatory drivers like the European Green Deal. The company’s competitive advantage lies in its technical expertise, multiple production sites, and comprehensive product offerings. The website indicates active marketing and recruitment efforts, suggesting growth ambitions. The presence of LinkedIn and detailed contact information supports a transparent and professional business approach. However, the lack of privacy and security policies may pose compliance risks. The company appears to be independent with no parent or subsidiary companies listed. The domain age aligns with the company’s founding year, supporting legitimacy.

Security posture

The website employs HTTPS with a valid SSL certificate and has domain transfer protection enabled, which are positive security indicators. However, the absence of DNSSEC reduces DNS security. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which could expose the site to certain web-based attacks. There is no published security policy or incident response contact, limiting transparency and preparedness communication. The use of third-party tracking scripts like Google Analytics and Facebook Pixel without visible cookie consent mechanisms raises privacy compliance concerns under GDPR. No vulnerabilities or exposed sensitive data were identified in the HTML content. Overall, the security posture is moderate but could be significantly improved by implementing recommended security headers, DNSSEC, and privacy compliance measures.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  3. Publish a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and other privacy regulations.
  4. Develop and publish a security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update all plugins and third-party scripts to minimize vulnerability risks.

Technical notes

Notes

The website is built on WordPress 6.8.2, utilizing popular plugins including Yoast SEO for search engine optimization, WP Job Openings for recruitment, and Site Kit by Google for analytics integration. The front-end uses jQuery and Swiper.js for interactive elements like sliders. Performance is moderate with caching enabled via W3 Total Cache and lazy loading of images. The site is mobile optimized with responsive design and basic accessibility features. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data. Hosting details are not explicit but the domain registrar is Ascio Technologies. The technical stack is modern and appropriate for the business needs, though some improvements in security and privacy implementation are recommended.
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.
