Risk levelMedium

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

South East Water is a regional water supplier in the United Kingdom providing drinking water services and customer notifications such as AquAlerter for water interruptions. The website is built using modern web technologies including React and Gatsby, with Bootstrap and Font Awesome for styling and icons. The technical infrastructure indicates a moderate level of digital maturity with good mobile optimization and basic SEO and accessibility features. However, the website lacks visible privacy and cookie policies, security headers, and explicit contact information, which are important for compliance and trust. The WHOIS data query failed due to querying a subdomain rather than the registered domain, limiting the ability to verify domain registration details. Overall, the website content is accessible and safe for general audiences, but improvements in security posture and privacy compliance are recommended.

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. 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';…

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

South East Water operates as an essential utility service provider in the energy sector, targeting residential and business customers in South East England. Their business model focuses on water supply and customer service, with features like AquAlerter to keep customers informed. The company appears to have a consistent brand presence online, though detailed business information such as founding year or parent company is not available from the provided data. The lack of visible trust indicators such as certifications or testimonials suggests room for enhancing business credibility. The website's moderate technical implementation supports their service delivery but could benefit from improved compliance and security transparency to strengthen customer trust and regulatory adherence.

Security posture

The website currently exhibits a low security posture with no detected security headers and no visible security or incident response policies. The absence of privacy and cookie policies indicates potential compliance gaps with GDPR and other data protection regulations. No vulnerabilities or exposed sensitive data were identified in the provided content, but the lack of security best practices such as secure forms and headers is a concern. The WHOIS data unavailability further complicates trust verification. To improve security maturity, the organization should implement standard security headers, enforce HTTPS, provide clear privacy and cookie policies, and establish incident response contact channels. These steps will reduce risk and enhance the organization's security culture and compliance readiness.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear consent mechanisms to ensure GDPR compliance.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  3. Ensure all website traffic is served over HTTPS with strong SSL/TLS configuration.
  4. Provide clear and accessible contact information including security incident response and data protection officer contacts.
  5. Verify and publish accurate WHOIS domain registration information to improve trust and legitimacy.

Technical notes

Notes

The website uses a modern front-end stack with React and Gatsby, leveraging Bootstrap 4.6.1 and Font Awesome for UI components and icons. This indicates a contemporary approach to web development with good mobile responsiveness and moderate performance. However, the absence of detected CMS or hosting provider details limits insight into backend infrastructure. The HTML content is valid and well-structured but lacks advanced SEO and accessibility features. There is no evidence of analytics or tracking services in the provided snippet, suggesting minimal user tracking. Technical debt appears low, but the lack of security headers and privacy compliance features represents a technical risk that should be addressed to align with best practices and regulatory requirements.
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.
