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

Siegfried AG is a well-established contract development and manufacturing organization (CDMO) specializing in pharmaceutical ingredients and finished products. With a history spanning 150 years and a global footprint of 13 production sites, the company holds a strong market position in the healthcare manufacturing sector. Their services cover drug substances, drug products including various dosage forms, and advanced technologies, targeting pharmaceutical companies and healthcare stakeholders worldwide. The website reflects a professional and comprehensive digital presence, supporting investor relations, career opportunities, and sustainability initiatives. Technically, the website is built on WordPress with modern integrations such as HubSpot for marketing and analytics, Vimeo for video content, and CookieYes for cookie consent management. The site is mobile-optimized, fast-loading, and SEO-friendly, with structured data enhancing search visibility. Security-wise, the site enforces HTTPS and uses secure external scripts but lacks some advanced security headers and explicit security policies or incident response contacts. Overall, the security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. The domain registration data aligns well with the company's identity and history, supporting legitimacy and trustworthiness. Strategic recommendations include enhancing security headers, publishing a security policy, and adding a vulnerability disclosure mechanism to further strengthen trust and compliance.

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

3 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

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

Siegfried AG operates as a global CDMO with a diversified service portfolio in pharmaceutical manufacturing. Their competitive advantage lies in their extensive experience, integrated supply chain, and multiple production sites across continents. The business model focuses on B2B services for pharma companies, offering both drug substance and drug product manufacturing. Revenue streams likely include contract manufacturing agreements and technology licensing. The company targets pharmaceutical innovators, investors, and potential employees, emphasizing growth and sustainability. Partnerships such as with Dinamiqs indicate strategic expansion into viral vector technologies. The website's investor and media sections reflect transparency and active stakeholder engagement, supporting growth and market confidence.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and no evident exposure of sensitive information. Use of secure external scripts and cookie consent mechanisms indicate attention to privacy and security. However, the absence of key security headers (e.g., CSP, X-Frame-Options) and lack of published security policies or incident response contacts represent gaps that could be addressed to improve resilience and transparency. No vulnerability disclosures or security.txt files were found, limiting external security collaboration. Overall, the site is secure for typical user interactions but could benefit from enhanced security controls and documented policies to meet higher compliance standards such as ISO 27001 or NIST frameworks.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page outlining security practices and compliance frameworks.
  3. Establish and publicize an incident response contact channel (e.g., security@ or abuse@ email).
  4. Create and maintain a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.

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.
