Risk levelHigh

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

ISO-Plus is a medium-sized Hungarian company specializing in insulated piping systems for energy transport, including district heating, cooling, industrial pipelines, and bioenergy sectors. The company operates within the energy and transportation sectors and maintains a consistent brand presence with multilingual support, indicating a regional European footprint. The website is built on TYPO3 CMS with legacy JavaScript libraries and includes standard business content and navigation. Technical infrastructure is moderate with basic mobile optimization and SEO. Security posture is adequate with HTTPS and cookie consent mechanisms but lacks advanced security headers and explicit incident response policies. Privacy compliance is basic with a privacy policy and cookie banner present. No contact emails or phone numbers are directly visible on the homepage, which may impact user engagement. Overall, the website is professional and trustworthy but could benefit from technical and security enhancements.

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 specialized supplier in the energy infrastructure market, focusing on sustainable and efficient heat and cooling transport solutions. Its business model is B2B, targeting industrial and municipal clients requiring insulated piping and network monitoring. The company leverages a group structure with multiple regional sites across Europe, indicating a broad partnership ecosystem. Revenue streams likely derive from product sales and service contracts related to piping systems and monitoring solutions. The multilingual website supports diverse European markets, enhancing growth potential. However, the lack of visible direct contact information on the homepage may limit immediate customer engagement. The company shows moderate digital maturity with room for modernization and improved security transparency.

Security posture

The website demonstrates a foundational security posture with HTTPS enforced and a cookie consent mechanism aligned with GDPR. Google Analytics is configured with IP anonymization, reflecting privacy awareness. However, the use of outdated jQuery versions and absence of key security headers such as Content-Security-Policy and X-Frame-Options present potential vulnerabilities. No explicit security policies or incident response contacts are published, which may hinder rapid response to security incidents. The lack of vulnerability disclosure or security.txt files reduces transparency. Overall, the security maturity 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 to enhance protection against common web attacks.
  2. Upgrade JavaScript libraries, especially jQuery, to current secure versions to mitigate known vulnerabilities.
  3. Publish clear security policies and incident response contact information to improve transparency and readiness.
  4. Add terms of service and vulnerability disclosure policies to align with best practices and regulatory expectations.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO performance.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, but uses an outdated jQuery version (1.4.3) and legacy Fancybox scripts, which may pose security risks. Google Analytics and Google Tag Manager are integrated for analytics and marketing, with IP anonymization enabled. The site includes a cookie consent plugin compliant with EU regulations. Performance is moderate with no explicit hosting provider identified. SEO and accessibility features are basic but functional. The site lacks advanced technical optimizations such as modern JavaScript frameworks or progressive web app features. Overall, the technical infrastructure is stable but could benefit from modernization and security hardening.
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.
