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

ZWP Anlagenrevision GmbH is a medium-sized German company specializing in non-destructive material testing, particularly using electromagnetic ultrasound techniques. Founded in 1975, it operates as a TÜV Saarland subsidiary and maintains certifications such as DIN EN ISO/IEC 17025 and ISO 9712, positioning itself as a trusted service provider in the energy and manufacturing sectors. Their services include light mast testing, pipeline inspection, and material testing with digital documentation and long-term certification. The website is professionally designed with good content relevance and navigation, targeting industrial clients and infrastructure operators. Technically, the website runs on a custom PHP stack with nginx and uses multiple jQuery libraries for UI enhancements. Hosting and DNS are managed through hgcloud.de and dodns.net respectively. However, the site suffers from an invalid or missing SSL certificate, no modern TLS protocols enabled, and lacks advanced DNS security features such as DNSSEC and CAA records. Cookie consent is implemented via CookieFirst, indicating some compliance with privacy regulations. From a security perspective, the site has significant gaps including no valid HTTPS, no HSTS, no DMARC, and no incident response or security policy disclosures. While the company demonstrates strong industry certifications and partnerships, the digital security posture is weak, exposing potential risks to data integrity and user trust. Immediate remediation of SSL and DNS security is recommended alongside publishing formal security policies. Overall, ZWP Anlagenrevision GmbH presents a solid business with good market positioning and service offerings but requires urgent improvements in its web security infrastructure to align with best practices and regulatory compliance.

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.

Business context

Business profile

ZWP Anlagenrevision GmbH operates in the specialized niche of non-destructive testing within the energy and manufacturing sectors, serving clients such as municipalities, energy providers, and industrial operators. Their competitive advantage lies in accredited certifications, long-term test certifications, and partnerships with reputable institutions like Fraunhofer and TÜV Saarland. The business model focuses on service delivery with digital documentation and innovative testing technologies. Growth indicators include a stable workforce of 30 employees and a strong regional presence since 1975. The partnership ecosystem enhances credibility and market reach. The company targets safety-conscious clients responsible for infrastructure maintenance, leveraging TÜV Saarland's network for market positioning. Revenue streams are likely service contracts and testing certifications. Strategic observations suggest potential for digital modernization and enhanced security posture to support business continuity and trust.

Security posture

The current security maturity level of the website is low due to the absence of a valid SSL certificate and lack of modern TLS protocols, exposing users to potential interception and data integrity risks. The missing DNSSEC and CAA records further weaken DNS security, increasing susceptibility to spoofing or hijacking. Email security is incomplete without DMARC, risking phishing attacks. No explicit security or incident response policies are published, indicating limited readiness for handling security incidents. The use of CookieFirst for consent shows awareness of privacy compliance but overall data protection practices are minimal. The absence of security.txt or vulnerability disclosure mechanisms reduces transparency and trust. Business impact includes reputational risk and potential regulatory non-compliance under GDPR and NIS2. Security culture indicators are not evident from the website. Immediate actions are needed to remediate these gaps and improve the security posture.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) and disable legacy insecure protocols.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  4. Configure DNSSEC and CAA records to enhance DNS security and certificate issuance control.
  5. Publish a DMARC record to improve email authentication and reduce phishing risks.
  6. Develop and publish a formal security policy and incident response plan accessible on the website.
  7. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  8. Remove or mask server and technology headers to reduce fingerprinting and attack surface.
  9. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  10. Enhance privacy compliance by documenting data retention policies and user tracking practices.

Technical notes

Notes

The website is built on a custom PHP 7.3.33 backend served by nginx, utilizing multiple jQuery plugins for UI features such as sliders, accordions, and modals. The hosting environment is linked to hgcloud.de for mail exchange and dodns.net for DNS services. Performance metrics are not available but inferred as slow due to zero load time and resource count data. Mobile optimization is good with responsive CSS files and viewport meta tags. SEO is basic with meta descriptions and keywords but no Open Graph or JSON-LD structured data detected. The absence of a CMS suggests custom development, which may increase maintenance overhead. The invalid SSL certificate and lack of modern TLS protocols represent significant technical debt and security risk. Opportunities exist to modernize the tech stack, improve performance, and enhance security configurations to support business operations and user trust.
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.
