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

Lintott is a specialized process solutions provider focused on the design, manufacture, and after-care of factory-built packaged water and wastewater treatment systems, along with process software integration and electrical control panels. The company positions itself as a pioneering and multi-award-winning entity serving industrial and business clients primarily in the energy and manufacturing sectors. The website is professionally designed and hosted on the Squarespace platform, indicating a moderate level of digital maturity with good mobile optimization and SEO practices. However, the absence of critical compliance documents such as privacy and cookie policies, as well as the lack of explicit contact information, limits the overall transparency and user trust. Security-wise, the site benefits from HTTPS and HSTS, but could improve by adding additional security headers and visible security policies. The WHOIS data is unavailable and indicates domain registration irregularities, which raises concerns about domain legitimacy despite the active website presence. Overall, the site is functional and professional but requires enhancements in privacy compliance and domain legitimacy verification to improve trust and security posture.

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. 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. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

  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

Lintott operates in a niche industrial market providing water and wastewater treatment solutions and related systems integration services. Its business model is B2B, targeting industrial clients requiring packaged treatment systems and control panels. The company leverages a multi-award-winning reputation to position itself competitively. The website reflects a medium-sized enterprise with consistent branding and good content relevance. The limited external partnerships visible are primarily through LinkedIn. The absence of detailed business registration or certification information on the site suggests opportunities to strengthen credibility. Revenue streams likely derive from manufacturing, software integration, and after-care services. Growth indicators and strategic partnerships are not explicitly detailed on the website.

Security posture

The website demonstrates a basic to moderate security posture with HTTPS and HSTS enabled, ensuring encrypted communications and protection against protocol downgrade attacks. However, the lack of additional security headers such as Content-Security-Policy, X-Frame-Options, and Referrer-Policy reduces defense-in-depth. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a security policy or incident response contact information limits the site's readiness for security incidents. Privacy compliance is weak, with no cookie consent or privacy policy present, which may expose the company to regulatory risks under GDPR or similar frameworks. The WHOIS data irregularity is a significant concern for domain trustworthiness. Overall, the security score is moderate but could be improved with enhanced headers, policies, and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to ensure GDPR and privacy compliance.
  2. Add standard security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy to strengthen security posture.
  3. Provide clear and accessible contact information including emails and phone numbers for general and security incident reporting.
  4. Investigate and resolve domain WHOIS irregularities to ensure domain legitimacy and improve trustworthiness.
  5. Establish a formal security policy and incident response plan publicly accessible to demonstrate security maturity and readiness.

Technical notes

Notes

The website is built on the Squarespace platform, utilizing modern web technologies including HTML5, CSS3, JavaScript, Google Fonts, and Font Awesome icons. The site loads resources from Squarespace's CDN and uses asynchronous loading for fonts and scripts, contributing to moderate performance. Mobile optimization is good, with responsive design and viewport settings. SEO is supported by proper meta tags including Open Graph and Twitter Cards. Accessibility features are basic but present. No legacy or vulnerable libraries were detected. The technical infrastructure is stable but could benefit from performance optimizations and enhanced accessibility compliance.
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.
