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

1 finding 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.

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

The firm targets corporate clients across diverse sectors, offering specialized legal services and consulting. Its business model focuses on delivering expert legal advice supported by technology-enabled solutions and alternative resourcing. The website's structured data and social media presence reinforce brand credibility and market reach. While WHOIS data is not publicly available, the firm's established reputation and consistent branding mitigate concerns. The firm appears to maintain a strong partnership ecosystem and invests in digital marketing and client engagement through analytics and tracking tools.

Security posture

The website employs HTTPS with strong SSL configuration and security headers, indicating a solid baseline security posture. Consent management for cookies and analytics is implemented, supporting GDPR compliance. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a public security policy, incident response contacts, or vulnerability disclosure program suggests areas for improvement in transparency and security maturity. The use of third-party analytics and tracking scripts should be regularly audited to mitigate supply chain risks.

Recommendations

  1. Publish a dedicated security policy and incident response information to enhance transparency and client trust.
  2. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Provide clear contact details for the Data Protection Officer or privacy team to support GDPR compliance.
  4. Regularly review and update third-party scripts and analytics tools to minimize security risks.
  5. Enhance website accessibility and performance monitoring to maintain high user experience standards.

Technical notes

Notes

The website uses modern front-end technologies including SVG icons managed by grunticon, asynchronous CSS loading, and Google Tag Manager for analytics deployment. Microsoft Application Insights is integrated for telemetry. The site is mobile-optimized with responsive design and accessibility features such as skip links and ARIA labels. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD organization schema. Performance appears moderate with deferred CSS loading and optimized assets. No CMS or hosting provider details are explicitly detected from the HTML content.
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.
