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

8 findings rated critical or high. Fix these first.

  1. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Policy found

      GDPR requires clear information about cookie usage

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

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

Campaign Monitor operates a SaaS business model focused on email marketing solutions. Their revenue streams likely include subscription plans (Essentials, Premier) and expert services. The company targets small to large businesses seeking scalable email marketing tools. The presence of integrations and marketing automation features indicates a competitive advantage in delivering personalized customer journeys. Their partnership ecosystem includes platforms like HubSpot and Segment, enhancing their marketing capabilities. The company maintains a consistent brand image and demonstrates growth through continuous feature updates and customer engagement.

Security posture

The website enforces HTTPS with strong SSL configuration and implements multiple security headers, reflecting a good security posture. Cookie consent mechanisms and privacy policies indicate compliance with GDPR and related regulations. However, the absence of a dedicated security policy page, incident response contacts, and vulnerability disclosure reduces transparency in security governance. The use of multiple third-party analytics and marketing scripts necessitates ongoing security audits to mitigate risks. Overall, the security maturity is good but could be improved by publishing explicit security documentation and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security controls and practices.
  2. Establish and publicize incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts to minimize exposure to vulnerabilities.
  5. Enhance transparency by providing contact information for the Data Protection Officer or privacy lead.

Notes

The website is built on WordPress CMS and leverages a modern technology stack including jQuery, Google Analytics, HubSpot, Hotjar, Segment, Demandbase, and HockeyStack for analytics and marketing automation. The site demonstrates fast performance, excellent mobile optimization, and good accessibility features. SEO is well-implemented with comprehensive metadata, Open Graph tags, and structured JSON-LD data. The technical infrastructure supports a professional and scalable digital presence, though hosting provider details are not explicitly identified. Continuous monitoring and modernization of the tech stack will help maintain performance and security.
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.
