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

2 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 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

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 zentiva.co.uk, from OffSeq Breach.

No leaked records found

Technical appendix

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

Business context

Business profile

Zentiva maintains a strong market position in the generic pharmaceuticals sector with a broad network of subsidiaries across Europe and India. The company emphasizes sustainability, transparency, and partnerships with healthcare providers such as the NHS. The website links to multiple country-specific Zentiva domains, indicating a well-established international presence. The business model leverages innovation and affordability to compete in the healthcare market, targeting institutional buyers and patients alike.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. It uses Google Tag Manager and Cookiebot for analytics and consent management. However, explicit security headers are not detected in the provided data, and no dedicated security or incident response policies are published. The site includes warnings for external links to mitigate risk. Overall, the security posture is good but could be improved by adding security headers and incident response information.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Regularly audit third-party scripts and tracking tools to minimize vulnerabilities and privacy risks.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Maintain and update GDPR and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses a modern but somewhat dated JavaScript stack including jQuery 2.2.4, Modernizr, and Select2, combined with Google Tag Manager and Cookiebot for analytics and consent management. The site is mobile responsive with good SEO meta tags and Open Graph data. Performance is moderate, with potential for optimization by updating libraries and improving caching. No CMS is explicitly detected. The hosting provider is not identified from the data. Accessibility is basic but present, and navigation is clear and user-friendly.
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.
