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

WELL OKNA s.r.o. is a Czech Republic-based manufacturer and supplier specializing in plastic and aluminum windows and doors, operating since 1991. The company targets residential and commercial customers primarily in the Plzeňský kraj region, offering products made from SCHÜCO profiles along with related accessories such as shading and ventilation technology. The website reflects a well-established regional business with a clear focus on manufacturing and direct sales. Technically, the website is built on WordPress with a modern tech stack including popular plugins for SEO, analytics, and cookie compliance, indicating a moderate level of digital maturity. Security posture is solid with HTTPS, security headers, and reCAPTCHA protections, though the absence of a public security policy and incident response contacts suggests room for improvement. Overall, the site is professional, trustworthy, and compliant with GDPR, with no signs of malicious activity or content blocking.

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

5 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"

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. 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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

The company holds a strong regional market position as a specialized manufacturer of plastic windows and doors, leveraging the reputable SCHÜCO brand for product quality. Its business model centers on manufacturing and direct sales, supported by a clear online presence and social media engagement. The website content and metadata emphasize local targeting and product expertise, which aligns with a small-sized manufacturing business. The absence of WHOIS data limits external verification but does not detract from the apparent legitimacy. The company could benefit from enhanced transparency in security and incident response to strengthen trust further.

Security posture

The website demonstrates good security hygiene with enforced HTTPS, presence of key security headers, and use of reCAPTCHA on forms to mitigate spam and abuse. Cookie consent mechanisms are implemented, supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of a published security policy, incident response information, and vulnerability disclosure reduces the overall security maturity. The company should consider publishing these documents and regularly auditing third-party scripts to maintain and improve security posture.

Recommendations

  1. Publish a comprehensive security policy and incident response plan on the website.
  2. Add clear contact channels for security incidents such as security@ or abuse@ email addresses.
  3. Regularly review and update third-party scripts and plugins to avoid vulnerabilities.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Consider establishing a vulnerability disclosure program to encourage responsible reporting.

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.
