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

Nelson Browne Management Ltd. operates as a UK-based talent management agency specializing in representing actors and directors for stage, screen, and corporate work. The company targets professionals in the performing arts sector and offers services including representation and casting support. The website content reflects a niche media business with a small operational scale and a focus on UK theatre and screen industries. Technically, the website is built with basic HTML, CSS, and JavaScript without modern frameworks or CMS detected. The site lacks mobile optimization and advanced SEO features, indicating a modest digital maturity level. Security posture is weak, with no HTTPS enforcement or security headers detected, and no privacy or cookie policies present, which raises compliance concerns. The WHOIS data for the domain queried is unavailable and indicates an invalid domain name, creating trust and legitimacy questions. Overall, the website is functional but requires significant improvements in security, privacy compliance, and technical modernization to enhance trust and user experience.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. 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

  3. 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"

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 · found on this site
  • 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

Nelson Browne Management Ltd. holds a niche position in the UK media sector, focusing on talent representation for actors and directors. The business model revolves around client representation and facilitating casting opportunities. The company leverages partnerships with theatre and production companies, as evidenced by external links to reputable theatre sites. Revenue streams likely derive from commissions and management fees. The target customer segment includes performing artists and casting professionals. Growth indicators are not explicit, but the presence of multiple client showcases suggests active engagement. The company operates independently without visible parent or subsidiary relationships. Strategic observations highlight the need for digital modernization and enhanced online presence to compete effectively in the talent management market.

Security posture

The current security maturity level is low. The absence of HTTPS and security headers exposes the website to risks such as data interception and clickjacking. No forms or input fields are present, reducing immediate attack surface, but lack of privacy and cookie policies indicates non-compliance with GDPR and related regulations. Incident response readiness is not demonstrated, with no security contact channels provided. The security culture appears minimal, with no visible certifications or policies. Vulnerabilities include potential data exposure and lack of secure communication channels. Business impact includes reputational risk and possible regulatory penalties. Immediate remediation is recommended to improve security posture and compliance.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all website traffic.
  2. Add comprehensive privacy and cookie policies to ensure GDPR compliance.
  3. Introduce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Establish clear incident response contact channels (e.g., security@ or abuse@ email addresses).
  5. Modernize website design to improve mobile responsiveness, accessibility, and SEO.

Technical notes

Notes

The website is constructed using basic HTML, CSS, and JavaScript without any detected CMS or modern frameworks. The site lacks mobile optimization and accessibility features, which may hinder user experience on diverse devices. Performance is moderate but could benefit from optimization. No analytics or tracking technologies are present, indicating minimal data collection. The absence of security headers and HTTPS suggests technical debt and potential risks. Hosting provider and infrastructure details are not discernible from the provided data. Overall, the technical implementation is functional but outdated, requiring modernization to meet current web standards and security best practices.
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.
