0–100, higher is better. How it is calculated

Mishcon de Reya LLP is a well-established independent law firm founded in 1973, with a significant international presence including offices in London and Singapore. The firm offers a broad range of legal and non-legal services across multiple sectors such as corporate law, dispute resolution, employment, innovation, and private client services. Their market position is strong, supported by a large team of over 1400 people and multiple subsidiaries and partner firms. The website reflects a professional and comprehensive digital presence with clear navigation and detailed service offerings. Technically, the website is built on ASP.NET Web Forms with modern web standards including responsive design, accessibility features, and SEO best practices. The site performance is moderate with good mobile optimization. Security measures include HTTPS enforcement and multiple security headers, indicating a mature security posture. However, explicit security policies and incident response information are not published, which could be improved. The overall risk profile is low with no detected vulnerabilities or suspicious content. The missing WHOIS data is a concern for domain registration transparency but does not detract significantly from the firm's credibility given the strong branding and external references. Strategic recommendations include publishing detailed security and incident response policies, adding vulnerability disclosure mechanisms, and verifying domain registration details to enhance trust.

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

  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • 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.

Business context

Business profile

Mishcon de Reya operates as a professional services law firm targeting businesses and individuals requiring legal expertise internationally. Their competitive advantage lies in their comprehensive service portfolio, international footprint, and strong brand reputation. Revenue streams likely derive from legal advisory, dispute resolution, and specialized consulting services. The firm maintains a partnership ecosystem with subsidiaries and related entities focused on analytics, legaltech incubation, and private advisory. Growth indicators include a large workforce and diversified service offerings. The company emphasizes innovation and impact, aligning with ESG and sustainability trends. Strategic observations suggest a focus on digital transformation and client-centric service delivery.

Security posture

The website demonstrates a high level of security maturity with HTTPS enforced and multiple security headers such as CSP, HSTS, and X-Frame-Options. Forms are secured with anti-forgery tokens, and no sensitive data is exposed in the HTML. However, the absence of publicly available security policies and incident response plans indicates a gap in transparency and preparedness communication. There is no evidence of vulnerability disclosure programs or security.txt files. Compliance with GDPR is indicated by privacy and cookie policies with consent mechanisms. Overall, the security posture is strong but could benefit from enhanced policy disclosures and incident response readiness.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to improve transparency and preparedness.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Verify and update WHOIS domain registration information to enhance trust and legitimacy.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance data protection officer contact visibility to comply with GDPR and improve user trust.

Technical notes

Notes

The website is built using ASP.NET Web Forms technology, leveraging modern HTML5, CSS, and JavaScript. The technical infrastructure supports responsive design and accessibility standards, providing a good user experience across devices. Performance is moderate, with potential for optimization in loading times and resource management. The site uses structured data (JSON-LD) for SEO and rich snippets, improving search engine visibility. There is no detected CMS, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Technical risks are minimal but include the need for ongoing maintenance of legacy ASP.NET Web Forms technology and ensuring third-party dependencies remain secure.
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.
