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

Celerion is a well-established clinical research organization specializing in translational medicine and early drug development services. The company offers a broad range of clinical research solutions, bioanalytical sciences, and regulatory affairs support, targeting pharmaceutical and biotech companies globally. Their website reflects a mature business with consistent branding, good content quality, and a clear focus on their specialized healthcare sector. Technically, the site is built on WordPress and hosted on Pantheon, utilizing modern marketing and analytics tools such as Google Tag Manager, Pardot, and LinkedIn Insight Tag. However, the website suffers from a critical security deficiency due to the absence of a valid SSL certificate and HTTPS support, which significantly impacts the security posture and trustworthiness of the site. Privacy and cookie policies are present with consent mechanisms, but no explicit security or incident response policies are found. WHOIS data confirms the domain's legitimacy and consistency with the business claims. Overall, while the business and content quality are strong, the lack of proper SSL/TLS security is a major concern that should be addressed promptly.

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

6 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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

Celerion operates in the healthcare sector as a contract research organization with a focus on translational medicine and clinical trial services. Their market position is strong, supported by decades of experience and a global footprint. The business model revolves around providing specialized clinical research and bioanalytical services to pharmaceutical and biotech clients, enabling faster drug development. The company leverages partnerships and participates in industry events to maintain visibility and credibility. Their digital presence is professional, with good SEO and marketing integration, but lacks direct contact details on the homepage, relying on contact forms. The absence of visible certifications or security policies on the website suggests potential areas for improvement in trust and compliance communication.

Security posture

The website's security posture is weak due to the lack of a valid SSL certificate and HTTPS support, exposing users to potential data interception risks. While several security headers are implemented, their effectiveness is undermined by the missing SSL layer. No vulnerabilities such as Heartbleed or POODLE were detected, but the absence of TLS protocols and strong cipher suites is a critical flaw. No incident response or security policy information is available, and no vulnerability disclosure or security.txt files are present. The cookie consent mechanism is implemented, but GDPR compliance is not clearly demonstrated. Overall, the site requires urgent remediation of SSL/TLS issues and enhancement of security transparency to improve trust and compliance.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or higher) and configure strong cipher suites.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Publish clear security policies, incident response procedures, and vulnerability disclosure information.
  5. Enhance GDPR compliance by providing detailed privacy notices and data retention policies.
  6. Add visible company contact information including verified emails and phone numbers to improve trust.
  7. Regularly audit and update security headers and cookie consent mechanisms.
  8. Consider obtaining and displaying relevant industry certifications to strengthen credibility.
  9. Improve accessibility features and performance metrics for better user experience.
  10. Maintain consistent branding and update content regularly to reflect company developments.
Technical notes

Notes

The website is built on WordPress CMS and hosted on Pantheon, leveraging a modern tech stack including jQuery, FontAwesome, Google Tag Manager, Pardot, and LinkedIn Insight Tag. SEO is enhanced using Yoast SEO plugin with structured data (JSON-LD) and Open Graph tags properly implemented. The site is mobile optimized with responsive design and uses cookie consent scripts for compliance. However, the lack of a valid SSL certificate and HTTPS support is a major technical deficiency. Performance data is unavailable, but the presence of caching headers and CDN usage (Varnish) suggests some optimization. The site uses multiple external scripts for analytics, marketing, and user interaction, which should be monitored for security and privacy compliance. Overall, the technical infrastructure is modern but requires urgent security upgrades.
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.
