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

7 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter, LinkedIn, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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

Dehns operates in the intellectual property legal services sector, targeting technology and innovation-driven clients. Their business model focuses on providing tailored IP protection and consulting services, leveraging their expertise and geographic presence in the UK, Germany, and Norway. The firm maintains a strong partnership ecosystem and a comprehensive service portfolio, supporting growth and competitive advantage. Their digital presence and content strategy indicate a focus on thought leadership and client engagement. The absence of direct contact emails and phone numbers on the homepage suggests a controlled communication approach, likely via contact forms and professional channels. The firm’s awards and rankings enhance market positioning and client trust.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and a cookie consent banner indicating GDPR awareness. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No public security or incident response policies were found, and no security.txt file is published for vulnerability disclosure. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The WHOIS data is missing, which is common for privacy-protected domains but should be monitored. Overall, the security posture is good but could be improved by implementing additional headers and publishing security policies.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a public security policy and incident response contact information to enhance transparency and trust.
  3. Create and host a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance contact information visibility with verified company emails and phone numbers for improved client trust.

Technical notes

Notes

The website is built on WordPress CMS with Bootstrap 5 framework, jQuery, and several modern JavaScript libraries such as AOS for animations and Slick Carousel for sliders. Google Tag Manager is used for analytics and marketing tags, and Google Fonts are loaded for typography. The site loads multiple videos and images hosted on Vimeo and AWS S3, indicating a robust media delivery setup. The site is mobile responsive and accessible, with good SEO metadata including Open Graph and JSON-LD structured data for rich search results. Performance is moderate due to video content but overall user experience is smooth. No major technical debt or outdated technologies were detected.
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.
