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

Yünsa Yünlü Sanayi Ve Ticaret A.Ş. is a leading Turkish manufacturer specializing in high-segment wool fabric production, established in 1973 and publicly traded on Borsa Istanbul. The company operates with significant production capacity in yarn and fabric manufacturing and maintains a strong market position as one of the top five global producers in its sector. The website reflects a professional corporate presence with detailed product offerings, company history, and investor relations information. Technically, the website employs modern web technologies including jQuery, Bootstrap, and various UI libraries, with integration of Google Analytics and Google Maps for enhanced user experience and tracking. The site is mobile-optimized and features good navigation and content quality. However, some security best practices such as explicit HTTP security headers and incident response information are missing. From a security perspective, the site uses HTTPS and has cookie consent mechanisms, but lacks visible security policies or vulnerability disclosure channels. The WHOIS data is notably absent or inaccessible, which raises questions about domain registration transparency despite the professional nature of the site content. Overall, the website presents a credible and professional business front with moderate technical maturity and security posture. Strategic improvements in security transparency and WHOIS data clarity would enhance trust and 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

10 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

Yünsa operates in the manufacturing sector focused on wool and textile fabrics, targeting apparel manufacturers and investors. Its competitive advantage lies in integrated production capabilities and a strong European market presence. The business model centers on fabric production and innovation, supported by R&D activities. The company has a clear ownership structure with majority shares held by Sürmegöz Tekstil Yatırım and remaining shares publicly traded. The website supports investor relations and corporate communications, indicating a mature business with growth and sustainability focus.

Security posture

The website demonstrates a baseline security posture with HTTPS usage and cookie consent compliance. However, it lacks explicit security headers and does not provide visible security policies or incident response contacts, which are important for transparency and trust. No vulnerability disclosure or security.txt files are present, limiting external reporting capabilities. The absence of WHOIS data is a concern for domain legitimacy verification. Overall, the security maturity is moderate but could be improved by adopting best practices in security headers, incident response, and domain registration transparency.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Clarify domain WHOIS registration details to improve transparency and trustworthiness.
  5. Conduct regular security audits of third-party libraries and update them to mitigate vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack with jQuery, Bootstrap, Slick Carousel, Fancybox, and Revolution Slider for UI and interactivity. Google Analytics and Tag Manager are integrated for analytics. The site is mobile-optimized and has good SEO meta tags. Performance is moderate, with potential improvements in loading speed and accessibility. No CMS is explicitly detected, suggesting a custom or static site architecture. Hosting provider details are not evident from the content. Overall, the technical implementation is solid but could benefit from enhanced accessibility and performance tuning.
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.
