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

6 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  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

stela operates in the manufacturing sector with a focus on drying technology for multiple industrial sectors including agriculture and energy. Their business model is B2B, providing both products and lifecycle services such as maintenance and spare parts. The company has a medium size with a long history dating back to 1922, and maintains a subsidiary specializing in control technology. Their competitive advantage lies in specialization, quality certifications, and global reach. The website supports lead generation and customer engagement through detailed references, case studies, and career opportunities. Partnerships include a dedicated control technology subsidiary and a Chinese market partner. Growth indicators include active news updates and participation in international trade fairs. The company maintains a strong brand presence and trust signals through certifications and social media.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a cookie consent mechanism aligned with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy and incident response contact information limits transparency. There is no security.txt file for vulnerability disclosure. The use of third-party scripts such as Google Tag Manager and Matomo is consent-based, reducing privacy risks. Recommendations include formalizing security policies, publishing incident response contacts, and implementing a security.txt file to improve security culture and readiness.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and commitments.
  2. Add a security.txt file at the root domain to facilitate vulnerability disclosures.
  3. Provide explicit incident response contact channels such as security@ or abuse@ emails.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by including data protection officer contact information if applicable.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used open-source content management system. It uses jQuery and integrates Google Tag Manager and Matomo for analytics and tag management. The hosting is inferred to be with Strato based on nameservers. The site is well-structured with valid HTML and CSS, optimized for mobile devices, and includes SEO best practices such as meta tags and structured data (JSON-LD). Performance is moderate, with asynchronous loading of scripts and preloading of fonts. Accessibility features are present, and navigation is clear and consistent. Technical risks are minimal but include the need for continuous monitoring of third-party dependencies and ensuring compliance with evolving privacy regulations.
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.
