Risk levelMedium

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

HIS is a German-based, medium-sized company specializing in energy infrastructure solutions, including plug-and-play cabling, energy management systems, battery storage, and EV charging solutions. The company positions itself as a leading European provider in this sector, targeting B2B customers such as installers, industrial clients, and utilities. The website is professionally designed using modern technologies like Nuxt.js and Tailwind CSS, offering a good user experience and mobile optimization. However, there is a lack of explicit privacy and cookie policies, which impacts compliance. Security posture is decent with HTTPS enabled and domain transfer protection, but lacks DNSSEC and security headers. Analytics is implemented via Google Tag Manager, indicating moderate user tracking. Overall, the domain registration data aligns well with the business claims, supporting legitimacy.

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 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';…

  2. GDPR outside view

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

    • 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

  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

HIS operates in the renewable energy sector, focusing on providing comprehensive cabling and energy system solutions. Their business model is B2B, serving installers and energy project developers with pre-assembled cable harnesses, energy storage, and management systems. The company leverages partnerships and industry events to strengthen market presence. Their website content and branding are consistent and professional, supporting a strong market position in Europe. Growth indicators include participation in trade fairs and a diverse product portfolio. No parent or subsidiary companies were identified from the data.

Security posture

The website employs HTTPS with a valid SSL certificate and has domain transfer protection enabled, which are positive security indicators. However, DNSSEC is not enabled, and no security headers were detected in the provided data, which are areas for improvement. There is no visible security policy, incident response contact, or vulnerability disclosure mechanism, which limits transparency and readiness for security incidents. The use of Google Tag Manager introduces moderate tracking but no explicit privacy controls were found. Overall, the security maturity is moderate but could be enhanced by implementing recommended best practices.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  4. Publish a security policy and incident response contact information to increase transparency and preparedness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website is built on a modern technology stack including Nuxt.js and Vue.js, styled with Tailwind CSS, and uses Storyblok as a CMS. It is mobile optimized and has good SEO metadata including Open Graph tags. Performance appears moderate with lazy loading of images and videos. Google Tag Manager is used for analytics and tracking. No major technical debt or outdated libraries were detected in the provided content. Hosting provider details are limited but domain registrar is reputable. The site lacks some accessibility features and security headers, which could be addressed to improve overall technical quality.
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.
