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

THEVA Dünnschichttechnik GmbH is a specialized German company founded in 1996, focusing on the production and supply of 2G high-temperature superconductors, notably the THEVA Pro-Line product. The company serves industrial sectors such as electrical engineering, power transmission, magnet technology, and manufacturing, offering innovative and efficient solutions that outperform traditional copper conductors. With a small but expert team and global presence through partners, THEVA positions itself as a niche leader in superconductivity technology. Technically, the website is built on WordPress with modern plugins for SEO and performance optimization. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. Security-wise, HTTPS is enforced, and cookie consent mechanisms are implemented, though explicit security headers and incident response policies are not evident. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, THEVA demonstrates a solid digital presence aligned with its business goals, maintaining compliance with GDPR and providing essential legal and privacy information. The absence of direct contact emails or phone numbers suggests reliance on contact forms for communication. The WHOIS data supports the legitimacy and consistency of the domain with the company's history and operations. Strategic recommendations include enhancing security headers, publishing explicit security and incident response policies, and providing direct contact information to improve trust and compliance further.

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

4 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. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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.

Dark web exposure

Add-on

Leaked records that mention theva.de, from OffSeq Breach.

No leaked records found

Breach holds no records for theva.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

THEVA operates in a specialized technology niche within the energy and manufacturing sectors, focusing on superconductors that enable significant efficiency gains. Their business model is B2B, targeting manufacturers and industrial clients requiring advanced electrical components. The company has a stable market position with patented technology and investor backing since 2012, indicating growth potential. Their global reach via partners in Asia and the USA supports international expansion. The website content and structure reflect a professional and focused approach, emphasizing innovation and quality. Partnerships like ivsupra.de suggest a collaborative ecosystem enhancing their market offerings.

Security posture

The website exhibits a moderate security posture with HTTPS enabled and cookie consent implemented, reflecting GDPR compliance. However, the lack of visible security headers such as Content-Security-Policy or X-Frame-Options and absence of published security policies or incident response contacts indicate areas for improvement. No vulnerabilities or sensitive data exposures were found in the HTML content. The security score is good but could be enhanced by adopting additional best practices and transparency measures to strengthen user trust and regulatory compliance.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Provide direct company contact emails and phone numbers to improve communication transparency.
  4. Regularly audit and update WordPress plugins and themes to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on WordPress 6.8.1 with Yoast SEO and WP Rocket plugins, indicating a modern CMS environment optimized for SEO and performance. The use of Fusion Builder and Borlabs Cookie plugin shows a focus on design flexibility and privacy compliance. The site is mobile responsive with good navigation clarity. Performance is moderate, with caching and lazy loading implemented. No hosting provider details were found in the content. The technical stack is appropriate for a small to medium-sized technology company, though improvements in security headers and accessibility could be made to reduce technical debt and enhance resilience.
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.
