Security score

45/100

Risk levelHigh

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

isoplus (Schweiz) AG is a Swiss-based company specializing in district heating systems, including high-quality heating pipes, heat transfer stations, control technology, and ceiling radiant panels. The company targets businesses and organizations in the energy and construction sectors, offering tailored heating solutions. The website reflects a professional and consistent brand presence with clear navigation and relevant business content. Technically, the site is built on WordPress with Bootstrap and jQuery, providing a moderate performance and good mobile optimization. However, some technical improvements are recommended, such as implementing security headers and properly configuring analytics tools. Security posture is adequate with HTTPS enabled but lacks advanced security headers and policies. Privacy compliance is weak due to missing privacy and cookie policies. Overall, the domain registration data aligns well with the business claims, indicating legitimacy and trustworthiness.

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: 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';…

  3. GDPR outside view

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

    • 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

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 company holds a specialist position in the Swiss district heating market, focusing on quality and customized solutions. Their business model is B2B manufacturing and service provision. The website content and structure support their market positioning with clear service offerings and contact information. The presence of terms of service and detailed product categories indicates a mature business operation. No partnerships or subsidiaries are explicitly mentioned on the site. The company appears medium-sized with a focused sector presence in energy.

Security posture

The website uses HTTPS, which is a fundamental security measure. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which could mitigate common web attacks. There is no visible incident response or security policy information, and no security.txt file for vulnerability disclosure. The Google Analytics plugin is present but not configured, indicating incomplete tracking setup. Forms are minimal and appear secure but lack explicit security features. Overall, the security posture is moderate but could be significantly improved with standard best practices.

Recommendations

  1. Implement essential security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common attacks.
  2. Publish a comprehensive privacy policy and cookie policy with GDPR compliance and implement a cookie consent mechanism.
  3. Configure or remove unused analytics plugins to avoid unnecessary data collection and potential privacy issues.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure and improve incident response readiness.
  5. Regularly audit and update all third-party libraries and plugins to mitigate vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website is built on WordPress CMS using Bootstrap for responsive design and jQuery for scripting. It loads Google Fonts (Roboto) and FontAwesome icons for UI elements. The site uses a carousel slider for featured content and has a structured navigation menu with dropdowns. Performance is moderate with no major issues detected, but some CSS and JS files are loaded from the same domain, which is good for control but may benefit from optimization. Accessibility is basic with some screen-reader text and labels present. SEO is basic with meta tags and structured navigation but lacks advanced SEO markup like Open Graph or JSON-LD structured data for business or product information.
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.
