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

Zentiva Group, a.s. operates a professional and comprehensive website focused on providing quality generic medicines primarily in Portugal and across multiple European and international markets. The company positions itself as a large healthcare entity with a strong emphasis on innovation, production, service, and sustainability. The website content is well-structured, professionally designed, and targets a broad audience including healthcare providers, pharmacies, and the general public. The presence of multiple international subsidiary domains indicates a broad market footprint and corporate maturity. Technically, the website employs a modern technology stack including jQuery, Google Tag Manager, Cookiebot for consent management, and Google Fonts, ensuring good performance and mobile optimization. Accessibility and SEO practices are well implemented, contributing to a positive user experience. The site uses HTTPS with excellent SSL configuration, though explicit security headers could be improved. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and cookie consent mechanisms. However, it lacks a publicly available security policy, incident response contacts, and vulnerability disclosure mechanisms, which are recommended for enhanced trust and compliance. No vulnerabilities or suspicious domains were detected, and no WAF or blocking mechanisms interfere with content access. Overall, Zentiva.pt is a trustworthy, professional, and compliant website representing a reputable pharmaceutical business. Strategic improvements in security headers and transparency around security policies would further strengthen its posture.

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.

Priority findings

5 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, LinkedIn, YouTube, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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';…

  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

Zentiva Group is a well-established pharmaceutical company specializing in generic medicines with a strong European and international presence. Its business model revolves around developing, producing, and distributing affordable healthcare products, targeting pharmacies, healthcare providers, and patients. The company leverages partnerships and subsidiaries across multiple countries to expand its market reach. The website content and linked domains reflect a mature corporate structure with a focus on sustainability and innovation. The company appears to have a stable market position with ongoing growth initiatives, as evidenced by recent news and strategic partnerships. The presence of career pages and sustainability reports indicates active corporate social responsibility and talent acquisition efforts.

Security posture

The website maintains a good security posture with HTTPS enabled and cookie consent implemented via Cookiebot. The use of Google Tag Manager allows controlled script management, reducing risks from third-party scripts. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to certain web-based attacks. No incident response or security contact information is publicly available, which limits transparency and readiness perception. No vulnerability disclosure or security.txt files were found, which are best practices for responsible security management. Overall, the site is secure but could benefit from enhanced security policy transparency and header implementation.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and provide dedicated incident response contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities from outdated components.
  5. Enhance user privacy and data protection disclosures to align with evolving GDPR and NIS2 compliance requirements.

Technical notes

Notes

The website uses a modern and stable technology stack including jQuery 2.2.4, Google Tag Manager, Cookiebot for cookie consent, and Google Fonts for typography. The HTML structure is valid and includes meta tags for SEO and social media (Open Graph and Twitter cards). The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA roles. Performance is moderate, with asynchronous loading of scripts and lazy loading of images. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site uses Google Maps integration for location display. Overall, the technical implementation is solid with room for improvement in security headers and performance optimization.
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.
