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

4 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 Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

123 Reg operates as a key player in the UK domain registration and web hosting market, leveraging its long-standing presence and comprehensive service portfolio. Its business model focuses on providing accessible and scalable online services to small and medium-sized enterprises and individual entrepreneurs. The company benefits from a strong brand reputation supported by extensive customer reviews and testimonials, as well as active social media engagement. Revenue streams are diversified across domain sales, hosting packages, email services, and Microsoft 365 offerings. The partnership ecosystem includes affiliate programs and integration with major platforms like Microsoft. Growth indicators include promotional campaigns and a focus on user-friendly tools such as website and online store builders. The company’s operations emphasize simplicity, reliability, and customer support, positioning it competitively in the technology sector.

Security posture

123 Reg demonstrates a mature security posture with mandatory HTTPS enforcement and absence of critical vulnerabilities. The site lacks some explicit security headers like Content-Security-Policy and X-Frame-Options, which are recommended to mitigate advanced threats. No signs of exposed credentials or sensitive data were detected. The use of secure forms and absence of vulnerable libraries indicate good development hygiene. Privacy policies are comprehensive and GDPR compliant, though incident response and security contact details are not explicitly published. The company’s security culture is reflected in its customer support and trust signals. To enhance security maturity, 123 Reg should implement additional HTTP security headers, establish a public vulnerability disclosure process, and provide clearer incident response information.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a security.txt file or equivalent vulnerability disclosure policy to facilitate responsible reporting.
  3. Enhance privacy policy with explicit incident response and data protection officer contact details.
  4. Regularly audit and update third-party scripts and libraries to prevent vulnerabilities.
  5. Maintain transparent communication of security practices to strengthen customer trust.

Technical notes

Notes

The website is built using React 18, leveraging modern JavaScript and CSS technologies for a responsive and accessible user experience. It employs a custom or proprietary CMS and is hosted likely on 123 Reg’s own infrastructure. Performance is moderate with optimizations for mobile devices and SEO best practices in place. The site uses Google Tag Manager for analytics and integrates Trustpilot for customer reviews. Technical risks are minimal, though some CSS errors were noted in runtime but do not appear to impact functionality. Opportunities exist to improve security headers and streamline third-party script management to reduce potential attack surface.
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.
