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

Cistermiser is a UK-based company specializing in the design, manufacture, and distribution of water and energy-saving solutions for commercial washrooms. Their product portfolio includes urinal and toilet flushing controls, infrared taps, shower panels, thermostatic mixing valves, washroom control systems, and related spares. The company operates multiple related websites indicating a group structure and targets commercial facility managers and businesses seeking efficient washroom solutions. The website is professionally designed with good navigation and content quality, supporting e-commerce via WooCommerce and integrating modern technologies such as Stripe for payments and Google Analytics for visitor insights. Privacy compliance is well addressed with a comprehensive cookie consent mechanism and GDPR adherence. Security posture is solid with HTTPS enforced and Cloudflare protections, though some security headers could be improved. The absence of WHOIS data due to domain registration issues reduces trust slightly, but overall the digital presence is mature and business credible.

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

2 findings rated critical or high. Fix these first.

  1. 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

  2. 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 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
  • 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

The company holds a strong market position in the energy-saving commercial washroom sector, leveraging a diversified product range and multiple related domains to serve different market segments. Their business model combines manufacturing with direct online sales and distribution. The presence of detailed product categories and resources indicates a focus on customer education and support. The lack of direct contact emails or phone numbers on the site suggests a preference for controlled communication channels, possibly to manage sales and support efficiently. The company appears to be medium-sized with a UK focus and a well-established brand identity.

Security posture

The website demonstrates a good security baseline with HTTPS, bot management via Cloudflare, and secure payment processing through Stripe. Cookie consent is granular and GDPR-compliant, enhancing privacy protections. However, the site lacks explicit security policies, incident response contacts, and some recommended security headers, which are important for transparency and defense in depth. No vulnerabilities or exposed sensitive data were detected in the analysis. The domain registration inconsistency is a concern but may be due to subdomain usage or registration under a different domain. Overall, the security posture is good but could be enhanced with formal policies and additional headers.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add recommended security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve defense against common web attacks.
  3. Verify and correct domain registration details to ensure consistency and improve trustworthiness.
  4. Provide clear company contact emails and phone numbers to enhance business credibility and customer trust.
  5. Regularly audit and update WordPress and WooCommerce plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress 7.0.1 with WooCommerce 10.7.0, leveraging jQuery and modern payment gateways like Stripe. It uses Cloudflare services for load balancing and bot management, enhancing availability and security. The site includes a comprehensive cookie consent plugin (WebToffee) supporting GDPR compliance. Performance is moderate with room for optimization. Mobile responsiveness and SEO are well addressed. Accessibility is basic and could be improved. The technical stack is modern and appropriate for an e-commerce business in the energy-saving sector, but some technical debt is indicated by missing security headers and incomplete WHOIS data.
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.
