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

Lumos AI is a technology company specializing in AI-powered legal execution infrastructure, primarily targeting M&A legal workflows by automating disclosure schedule preparation. The platform leverages Microsoft Azure OpenAI services, which are certified under multiple global security standards, to deliver efficient document extraction, analysis, and draft generation. The website presents a professional and modern design with clear messaging aimed at legal professionals and law firms. However, the absence of explicit privacy, cookie, and terms of service policies, as well as lack of visible contact information, limits transparency and user trust. The domain WHOIS data is inconsistent, showing a future creation date and a registrant organization not referenced on the site, which raises legitimacy concerns that should be addressed.

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

9 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

Lumos AI positions itself as an innovative legal technology provider focused on automating time-consuming manual tasks in M&A deal document preparation. Its SaaS business model targets law firms and legal practitioners seeking efficiency gains. The company leverages AI and cloud infrastructure to differentiate itself in a competitive legal tech market. Customer testimonials from reputable law firms indicate early adoption and positive reception. The lack of detailed business registration information and contact details on the website suggests a startup or early-stage company still developing its public-facing compliance and support infrastructure.

Security posture

The security posture is anchored on the use of Microsoft Azure OpenAI, which provides strong compliance certifications including SOC 1/2/3, ISO 27001/27018, HIPAA/HITECH, GDPR, and FedRAMP High. The website states that no contract data is stored or viewed and that data is deleted immediately after processing, indicating good data protection practices. However, the absence of published security policies, incident response contacts, and security headers on the website reduces transparency and may impact user confidence. DNSSEC is not enabled, and domain registration inconsistencies further reduce trust. Overall, the security maturity is moderate but could be improved with better public documentation and technical controls.

Recommendations

  1. Publish comprehensive privacy, cookie, and terms of service policies to improve transparency and compliance.
  2. Add visible contact information including support and security incident response channels.
  3. Enable DNSSEC and implement security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  4. Verify and correct domain WHOIS registration details to align with company branding and improve legitimacy.
  5. Implement a cookie consent mechanism to comply with GDPR and other privacy regulations.

Technical notes

Notes

The website uses modern web technologies including ES modules and external font services, likely built as a single-page application. Hosting and AI processing rely on Microsoft Azure OpenAI, a robust and compliant cloud platform. Performance is moderate with good mobile optimization and SEO meta tags present. However, accessibility features are basic and no CMS or analytics tools are detected. The domain is registered via GoDaddy but lacks DNSSEC and has suspicious WHOIS data. No forms with data collection fields are visible except for sign-in and sign-up buttons, indicating limited direct user data capture on the public site.
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.
