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 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';…

  2. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

STG operates in a niche industrial technology market, focusing on combustion control and process optimization for glass manufacturing and related heavy industries. Their business model is B2B, providing tailored engineering solutions and hardware/software integration. The company demonstrates stable growth and market credibility through certifications and a detailed corporate history. Their partnership with Flammatec and multilingual website presence indicate international reach and collaboration. Revenue streams likely include product sales, engineering services, and maintenance contracts. The target customers are industrial manufacturers requiring energy-efficient and environmentally compliant combustion systems. The company’s strategic positioning leverages technical expertise and customization, differentiating it from generic automation providers.

Security posture

The website exhibits a moderate to good security posture with HTTPS enforced and a GDPR-compliant cookie consent mechanism. No critical security headers were detected in the HTML, which could enhance protection against common web attacks. There is no visible security policy or incident response contact information, which limits transparency and preparedness communication. No vulnerabilities or sensitive data exposures were found in the content. The use of updated WordPress and plugins reduces risk but requires ongoing maintenance. Absence of a vulnerability disclosure or security.txt file suggests limited public security engagement. Overall, the security maturity is adequate for the business size but can be improved with better header policies and incident response documentation.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  2. Publish a formal security policy and provide clear incident response contact channels to improve transparency and readiness.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve security posture.
  4. Maintain regular updates of WordPress core and plugins to mitigate emerging vulnerabilities.
  5. Enhance monitoring and auditing of third-party scripts and consent mechanisms to ensure ongoing privacy compliance.

Technical notes

Notes

The website is built on WordPress 6.7.2 with a suite of plugins including Yoast SEO for search optimization, WPML for multilingual support, and Download Manager for file handling. The front-end uses jQuery 3.7.1 and Beaver Builder for layout and design. Cookie consent is managed by Consentmanager.net scripts. The site is responsive and optimized for mobile devices with good accessibility features. Performance is moderate, with some large images and multiple scripts that could be optimized further. No hosting provider details were explicitly detected. The technical stack is modern and well-maintained but could benefit from enhanced security headers and performance tuning.
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.
