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.

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

Proofpoint holds a strong market position in the cybersecurity sector, focusing on email protection and data security governance. Their business model revolves around enterprise software sales and services, targeting large organizations with complex IT environments. The company maintains a broad partner ecosystem and provides extensive resources, including certifications and security advisories. The website content and structure support their positioning as a trusted provider with a comprehensive product portfolio and global reach.

Security posture

The website exhibits a robust security posture with enforced HTTPS, multiple security headers, and adherence to recognized frameworks such as ISO 27001 and SOC 2. The presence of PGP-signed software releases and dedicated security advisory contacts indicates mature incident response capabilities. No vulnerabilities or exposed sensitive data were detected. Privacy policies and cookie consent mechanisms align with GDPR requirements, supporting compliance. However, the absence of a security.txt file and explicit Data Protection Officer contact are areas for improvement.

Recommendations

  1. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  2. Provide clear contact information for the Data Protection Officer to enhance GDPR compliance.
  3. Enhance cookie consent mechanisms with granular user controls.
  4. Regularly audit and update third-party scripts to minimize security risks.
  5. Disclose data retention policies explicitly to build user trust.

Technical notes

Notes

The website is built on Drupal CMS and employs a modern technology stack including JavaScript frameworks and multiple analytics and marketing integrations such as Google Tag Manager, New Relic, and Visual Website Optimizer. Performance is moderate with good mobile optimization and accessibility features. The site uses canonical and hreflang tags for SEO and supports multiple languages. Technical risks are minimal, but continuous monitoring of third-party scripts is advised to prevent potential vulnerabilities.
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.
