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

ZETA is a large, established engineering and consulting company specializing in the pharmaceutical and biotech industries. They provide comprehensive services including process engineering, automation, food engineering, lifecycle management, and digitalization solutions. The company operates globally with multiple locations and a strong market presence in Austria and beyond. Their website reflects a professional and content-rich digital presence targeting industry clients seeking advanced technological solutions. Technically, the website is built on the Contao CMS platform, served by Apache, and uses common web technologies such as jQuery and Google Tag Manager. While the site is well-structured and optimized for mobile devices, performance metrics indicate slow loading times, and accessibility features are basic. SEO practices are good with proper meta tags and Open Graph data. From a security perspective, the site lacks a valid SSL certificate and does not support modern TLS protocols, which is a critical vulnerability. Security headers are partially implemented, but important features like HSTS, OCSP stapling, and session resumption are missing. The extensive use of tracking and marketing tools is managed with a clear cookie consent mechanism, indicating good privacy compliance. Overall, the website presents a trustworthy and professional business front but requires urgent improvements in SSL/TLS security to protect user data and enhance trust. The domain registration data aligns well with the business claims, supporting legitimacy. Strategic recommendations include immediate SSL certificate installation, enabling modern security protocols, and enhancing security headers to meet industry best practices.

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. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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
  • 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

ZETA positions itself as a key player in the pharmaceutical and biotech engineering sector, offering end-to-end solutions from concept to implementation. Their business model focuses on delivering high-quality, customized engineering services with a strong emphasis on innovation and sustainability, including decarbonization and digital twin technologies. The company targets large pharmaceutical manufacturers and biotech firms globally, leveraging a network of 31 locations and 1400 employees. Their marketing ecosystem includes major platforms like Google Ads, Microsoft Advertising, and Meta Pixel, supporting extensive lead generation and customer engagement. The presence of multiple success stories and innovation drivers on the site highlights their competitive advantage and commitment to customer satisfaction.

Security posture

The current security posture of the website is weak due to the absence of a valid SSL certificate and lack of HTTPS support, exposing users to potential data interception and man-in-the-middle attacks. Although some security headers are present, critical protections such as HSTS and OCSP stapling are not enabled, reducing the site's resilience against common web attacks. The site uses multiple third-party tracking and marketing scripts, which are managed through a consent mechanism, reflecting awareness of privacy regulations. However, the lack of incident response contact information and security policy documentation indicates gaps in security governance. Immediate remediation of SSL/TLS issues and enhancement of security policies are necessary to elevate the security maturity level.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate supporting TLS 1.2 and TLS 1.3 protocols.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Implement OCSP stapling to improve certificate revocation checking performance and security.
  4. Activate session resumption mechanisms such as session tickets or session cache for better security and performance.
  5. Publish a clear security policy and incident response contact information to improve transparency and readiness.

Notes

The website is powered by Apache and built on the Contao Open Source CMS, utilizing jQuery and several JavaScript libraries including Colorbox and Swipe.js for UI enhancements. Google Tag Manager is used for managing analytics and marketing tags. The site supports multiple languages and includes comprehensive meta tags and Open Graph data for SEO and social sharing. Performance metrics indicate slow loading times and zero resource/page size data, suggesting potential measurement gaps or optimization opportunities. Mobile optimization is good, but accessibility features are basic. The DNS setup is standard without DNSSEC or CAA records, and the SSL configuration is currently invalid, representing a significant technical risk.
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.
