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

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

ALUKOV operates in the manufacturing sector with a focus on aluminum roofing and enclosure solutions for residential and commercial clients. Their competitive advantage lies in their tailored product offerings, extended warranties, and global reach through multiple localized websites. The company targets homeowners, businesses, and public institutions seeking high-quality, durable roofing solutions. Revenue streams likely include direct sales, installation services, and after-sales maintenance. The presence of multiple language sites and international social media channels indicates a strategic approach to market expansion and customer engagement. The company maintains a strong brand image supported by positive customer reviews and testimonials, enhancing credibility and customer trust.

Security posture

The website exhibits a solid security foundation with HTTPS enabled and integration of Google reCAPTCHA to protect forms from abuse. Cookie consent mechanisms comply with GDPR requirements, enhancing privacy compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No visible vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or incident response contact reduces transparency in security governance. No vulnerability disclosure or security.txt file was found, which could limit external security reporting. Overall, the security posture is good but could be strengthened by adopting additional best practices and transparency measures.

Recommendations

  1. Implement explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures to improve transparency and trust.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security collaboration with external researchers.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.

Technical notes

Notes

The website is built using modern web standards including HTML5, CSS3, and JavaScript ES modules. It leverages the Nette Framework, a PHP-based framework, inferred from form attributes and data-controller usage. Performance is moderate with asynchronous loading of analytics and tag manager scripts. The site is highly mobile-optimized and accessible, featuring clear navigation and structured content. SEO practices are well implemented with meta tags, Open Graph, and Twitter card metadata. The hosting provider is not explicitly identified. The site uses CDN services for fonts and static assets, improving load times. Technical risks are minimal, but the absence of some security headers and incomplete WHOIS data represent areas for technical improvement and risk mitigation.
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.
