85/100

Risk levelLow

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

PHD Worldwide is a well-established global media agency founded in London in 1990, specializing in strategic and creative media planning and buying. The company positions itself as a next-generation agency network engineered for intelligence and connectivity, targeting businesses seeking comprehensive media services worldwide. The website reflects a professional and consistent brand image with multi-language support and a clear navigation structure. Technically, the site is built on WordPress, leveraging modern tools such as Google Tag Manager and OneTrust for cookie consent, ensuring GDPR compliance and good SEO practices. Security posture is strong with HTTPS enforced and appropriate security headers, although no explicit security policy or incident response information is published. The absence of WHOIS registration data is a notable anomaly that reduces trustworthiness and warrants further investigation. Overall, the website is professional, secure, and privacy-conscious, but the domain registration inconsistency is a risk factor.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Business profile

PHD Worldwide operates in the media sector as a strategic and creative media agency network with a global footprint. Its business model focuses on providing media planning and buying services to corporate clients, leveraging a network of offices worldwide. The company benefits from a strong brand legacy since 1990 and maintains a multilingual website to serve diverse markets. The presence of official publications and a comprehensive locations directory indicates a mature partnership ecosystem and operational scale. The lack of visible certifications or security accreditations suggests room for improvement in trust signaling. The missing WHOIS data is unusual for a company of this size and could impact business credibility if not clarified.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, modern security headers, and a cookie consent mechanism aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure program limits transparency and preparedness perception. The missing WHOIS data raises concerns about domain legitimacy, which is a critical security trust factor. Overall, the site is secure from a technical standpoint but could enhance its security culture and communication to stakeholders.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including abuse and security email addresses.
  3. Implement and publicize a vulnerability disclosure policy and consider adding a security.txt file.
  4. Clarify domain registration details and ensure WHOIS data is accurate and publicly available.
  5. Enhance trust signals by obtaining and displaying relevant certifications or accreditations.

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery and Google Tag Manager. It uses OneTrust for cookie consent management, ensuring compliance with privacy regulations. The site is mobile-optimized with responsive design and good accessibility features. SEO is well implemented with Yoast SEO plugin and proper meta tags including Open Graph and JSON-LD structured data. Performance is moderate, with asynchronous loading of scripts and optimized font loading. No major technical debt or outdated libraries were detected. Hosting provider details are not explicit from the HTML content. Overall, the technical infrastructure supports a professional and compliant digital presence.
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.
