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. Network security

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

    • Critical

      Critical Service Exposed: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. 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';…

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 · found on this site
  • 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 business operates as a project coordinator for interior construction and furnishing projects, serving diverse industries. Its market position is that of a specialized service provider with a focus on quality and international reach. The business model revolves around managing and coordinating complex projects rather than direct manufacturing or sales. The website reflects a professional image with consistent branding and good content quality. The absence of detailed contact information and certifications suggests a smaller scale operation. The company leverages partnerships with hosting and analytics providers but does not publicly disclose extensive business affiliations.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and a robust cookie consent framework compliant with GDPR. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers such as CSP, HSTS, and X-Frame-Options is a gap that could be addressed to enhance protection against common web attacks. There is no published incident response or vulnerability disclosure policy, which limits transparency in security management. The use of reputable plugins and regular updates is implied but not explicitly confirmed. Overall, the security posture is good but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen defense against web attacks.
  2. Publish a dedicated security policy and incident response plan to improve transparency and preparedness.
  3. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance contact information visibility to improve business credibility and user trust.
  5. Regularly audit and update all plugins and themes to mitigate risks from outdated software.

Technical notes

Notes

The website is built on a modern WordPress platform using the Avada theme, layered with advanced sliders and interactive elements. It employs multiple plugins for analytics (MonsterInsights), cookie management (Borlabs Cookie), and user interface enhancements (Mystickyelements Pro, 3D Flipbook). The hosting is managed via kasserver.com, indicating a professional hosting environment. Performance is moderate with room for optimization, especially in loading times due to slider scripts. The site is mobile optimized and SEO friendly with proper meta tags and structured data. Accessibility features are basic but present. Technical risks include potential plugin vulnerabilities and lack of advanced security headers.
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.
