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

Calber is a UK-based, family-managed facilities management company established in 2003, offering a broad range of services including cleaning, property maintenance, security, and ancillary services. The company positions itself as a personal yet comprehensive service provider targeting businesses seeking integrated facilities management solutions. The website reflects a professional and consistent brand image with clear service descriptions and customer testimonials, supported by recognized certifications such as Safe Contractor and Cyber Essentials. Technically, the website is built on WordPress with modern web technologies including jQuery, Google Analytics, and reCAPTCHA for security. The site is mobile-optimized and SEO-friendly, though some accessibility features could be enhanced. Security posture is solid with HTTPS enforced and anti-bot measures on forms, but lacks explicit security headers and published security policies. Overall, the website demonstrates a mature digital presence with good privacy compliance, including GDPR cookie consent mechanisms and clear privacy and cookie policies. Contact information is comprehensive and easily accessible. The domain registration data aligns well with the business claims, indicating legitimacy and trustworthiness. Strategic recommendations include enhancing security headers, publishing a formal security policy and incident response contacts, and considering a vulnerability disclosure program to further strengthen 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

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 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 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

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

Calber operates in the facilities management sector with a medium-sized business model focused on delivering personalized and comprehensive services to commercial clients. Their competitive advantage lies in their family-managed approach, broad service portfolio, and recognized certifications. The company targets businesses requiring compliant and professional facilities management solutions. The presence of a customer portal domain suggests investment in client engagement and operational efficiency. The company’s market position is stable with a focus on quality and trust, supported by testimonials and certifications. Growth indicators include a well-maintained website with regular updates and a careers section indicating ongoing recruitment.

Security posture

The website exhibits a good security maturity level with HTTPS enforced and Google reCAPTCHA protecting contact forms against automated abuse. Cookie consent mechanisms demonstrate GDPR compliance. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents a potential area for improvement. No visible vulnerabilities or exposed sensitive data were detected. The lack of a published security policy or incident response contact limits transparency and readiness perception. Overall, the security posture is solid but could be enhanced by formalizing policies and improving HTTP security headers.

Recommendations

  1. Implement and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and update third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is powered by WordPress CMS with a modern tech stack including jQuery, FontAwesome, and Slick Carousel for UI components. SEO is enhanced via Yoast SEO plugin, and analytics are implemented through Google Analytics and Tag Manager. The site loads with moderate performance and is mobile responsive. The use of Google reCAPTCHA adds a layer of security to forms. Some technical debt is indicated by the absence of security headers and limited accessibility features. Hosting provider details are not explicit, but the domain is well maintained. Opportunities exist to optimize performance further and enhance security configurations.
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.
