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

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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

Manx Utilities operates as an essential public utility entity in the energy sector, serving the Isle of Man community. Its business model revolves around providing reliable utility services including electricity, water, and wastewater management. The company emphasizes sustainability and energy transition, as evidenced by dedicated sections on renewables and smarter living. The website's structured navigation and comprehensive content suggest a mature organization with a focus on customer engagement and regulatory compliance. The absence of explicit revenue or partnership details limits deeper financial insights, but the presence of government-related domains and public service links indicates strong institutional ties.

Security posture

The website demonstrates a basic to moderate security posture. It uses HTTPS for secure communication and provides a cookie consent mechanism, aligning with privacy best practices. However, it lacks visible security headers such as Content-Security-Policy or X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No direct contact information for security incidents or a security policy page was found, which could hinder incident response. The absence of a security.txt file or vulnerability disclosure policy suggests limited transparency in security management. Overall, while no critical issues were detected, enhancing security headers and publishing clear security policies would strengthen the site's security maturity.

Recommendations

  1. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  2. Publish a dedicated security policy and incident response information to enhance transparency and preparedness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Ensure all forms include anti-CSRF tokens and robust input validation to prevent injection attacks.
  5. Regularly review and update third-party libraries to avoid vulnerabilities.

Technical notes

Notes

The website is built using a combination of jQuery 1.11.0, Bootstrap 4.5.0, and Slick Carousel for UI components, along with Font Awesome 5 Pro for icons. It uses Google Fonts for typography and integrates Google Analytics and Tag Manager for user tracking. The site appears to be hosted on a platform supporting HTTPS, though specific hosting details are not evident. The presence of Umbraco CMS is inferred from internal document links. The site is mobile-optimized with responsive design and includes accessibility features such as skip links and ARIA attributes. Performance is moderate, with no explicit indicators of slow loading or errors. There is an opportunity to modernize the tech stack by updating jQuery and optimizing asset delivery.
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.
