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

3 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. 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

The company holds a strong market position in the Nordic manufacturing sector for heating and plumbing systems. Their business model focuses on supplying tailored solutions through prefabrication, enhancing installation efficiency. The multilingual website and related sister domains indicate a broad regional presence. The absence of direct contact details on the main page suggests a controlled B2B communication approach. The use of reputable third-party services for cookie consent and analytics reflects a mature digital marketing strategy. LK Systems is part of the LK Group, which includes subsidiaries specializing in valves and plastic pipes, indicating a diversified product portfolio within the HVAC industry.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and modern security headers implemented. The cookie consent banner is comprehensive and integrates Google Consent Mode with denied defaults, enhancing privacy compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy or incident response contact reduces transparency. There is no evidence of a vulnerability disclosure program or security.txt file, which could improve security communication. Overall, the site is secure but could benefit from enhanced security governance documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Add clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Include a terms of service page to improve legal transparency and user trust.
  5. Enhance visibility of company contact information to facilitate customer and partner communication.

Notes

The website uses a modern technology stack including Google Tag Manager, Cookie Information for consent management, and Font Awesome for icons. The CMS is Episerver (Optimizely), a robust enterprise content management system. Performance is moderate with good mobile optimization and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The site uses multiple external domains for analytics, marketing, and cookie management, all reputable and standard for enterprise websites. There is no indication of technical debt or outdated libraries in the provided HTML. Opportunities exist to improve technical documentation and security governance visibility.
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.
