Risk levelHigh

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

ISO-Plus is a medium-sized company operating in the energy sector, specializing in heat and cooling supply, industrial insulated piping, bioenergy, and network monitoring solutions. The company targets a broad audience with a focus on sustainable and efficient energy infrastructure. Their website is built on TYPO3 CMS and includes multiple language versions, indicating an international presence. The technical infrastructure is moderately modern, utilizing Google Analytics and retargeting tools, but includes some outdated libraries such as jQuery 1.4.3. Security posture is generally good with HTTPS and privacy compliance measures like cookie consent banners, but lacks advanced security headers and explicit incident response policies. The absence of WHOIS registrant data limits full trust verification, though the website content and structure suggest a legitimate business. Overall, the site is professional and functional but could improve in security and transparency.

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

8 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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
    • 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 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';…

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

ISO-Plus positions itself as a key player in the energy infrastructure market, offering specialized products and services for heat and cooling supply, industrial applications, and bioenergy. The company leverages a multi-regional approach with dedicated websites for various countries, enhancing market reach. Their business model is B2B, focusing on sustainable energy solutions. The presence of retargeting and analytics tools indicates active marketing efforts. However, the lack of visible contact information and WHOIS data may hinder trust for new clients. The company appears to maintain consistent branding and content quality, supporting a moderate market position with potential for growth through enhanced digital presence and security transparency.

Security posture

The website enforces HTTPS with anonymized IP tracking in Google Analytics, demonstrating baseline security and privacy awareness. However, the use of an outdated jQuery version introduces potential vulnerabilities. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which are recommended to mitigate common web attacks. The cookie consent mechanism aligns with GDPR requirements, but no explicit security or incident response policies are published. The absence of contact channels for security incidents reduces incident response readiness. Overall, the security posture is moderate but requires improvements to meet higher compliance and protection standards.

Recommendations

  1. Implement modern security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Upgrade jQuery and other JavaScript libraries to current secure versions.
  3. Publish explicit security policies and incident response contact information on the website.
  4. Enhance mobile responsiveness and accessibility to improve user experience and compliance.
  5. Increase transparency by providing clear company contact details and verifying WHOIS information.

Technical notes

Notes

The website is built on TYPO3 CMS with legacy JavaScript libraries such as jQuery 1.4.3 and uses Google Analytics and Google Tag Manager for tracking. The site loads multiple CSS and JS assets and includes retargeting scripts from Sklik and Google Ads. Performance is moderate with room for optimization. Mobile optimization and accessibility are basic but functional. SEO is supported by meta tags and structured navigation but could be improved with richer metadata and schema. Hosting provider details are not discernible from the data. The technical stack is stable but shows signs of technical debt due to outdated libraries and missing security headers.
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.
