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

6 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

  2. 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';…

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

Trethowans positions itself as a leading law firm in the South of England, targeting both business and individual clients. Their competitive advantage lies in their comprehensive service offerings, professional qualifications, and high standards of service. The firm leverages multiple marketing and analytics tools to maintain a strong digital presence and client engagement. Their partnership ecosystem includes recognized legal directories and accreditation bodies, enhancing their market credibility. Growth indicators include recent press releases and active content updates. The business model focuses on providing specialized legal advice tailored to client needs across various sectors.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented. Cookie consent is actively managed with a user-friendly banner and opt-in/out options. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact information indicates gaps in transparency and readiness. Compliance with GDPR is evident through privacy policies and cookie management. The use of third-party analytics and marketing scripts is balanced with privacy considerations. Overall, the security maturity is good but could be enhanced by publishing explicit security and incident response documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact channels such as security@ or abuse@ emails.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by including data retention policies and detailed privacy compliance information.

Technical notes

Notes

The website is built on a modern WordPress platform with WooCommerce for e-commerce capabilities. It uses a variety of JavaScript libraries including jQuery and Underscore.js, and integrates analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, and Webtrends Optimize. The site is well-structured with comprehensive metadata, Open Graph tags, and JSON-LD structured data for SEO. Performance is moderate with good mobile optimization and accessibility features. The technical infrastructure supports a professional user experience but could benefit from clearer hosting provider information and continuous performance monitoring to maintain fast load times.
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.
