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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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';…

  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 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

REMKO holds a solid market position in the energy sector, focusing on climate and heating solutions. Their business model revolves around manufacturing and distributing a diverse product portfolio tailored for various applications. The company targets both B2B and B2C customers, leveraging digital marketing tools such as Google Analytics and social media platforms to engage their audience. The presence of modular energy solutions and heat pumps indicates a focus on sustainable and new energy technologies. The company’s revenue and employee count suggest a stable medium-sized enterprise with growth potential in the European market.

Security posture

The website employs HTTPS with strong SSL configuration and includes key security headers, enhancing protection against common web threats. The use of a consent management platform (Klaro) aligns with GDPR requirements, and third-party tracking is managed with user consent. However, the absence of a published security policy or incident response contact limits transparency in security governance. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Recommendations include implementing a Content-Security-Policy header and publishing a security.txt file to improve security posture and incident response readiness.

Recommendations

  1. Implement a Content-Security-Policy (CSP) header to mitigate cross-site scripting and related attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Add a dedicated security policy page outlining security frameworks and practices.
  4. Include explicit incident response contact channels such as security@ or abuse@ email addresses.
  5. Regularly review and update third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website is built on TYPO3 CMS, utilizing modern front-end technologies including responsive images, Swiper.js for sliders, and a consent management system for privacy compliance. Hosting is managed via agenturserver with multiple nameservers indicating redundancy. Performance optimizations such as preloading fonts and images are implemented. SEO is enhanced through structured data (JSON-LD) and Open Graph metadata. Accessibility and mobile optimization are rated good, with semantic HTML and ARIA roles present. The technical infrastructure supports a professional and scalable web presence with room for further security enhancements.
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.
