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

ServiceCal Ltd is a UK-based calibration and repair service provider accredited by UKAS 17025 since 1985. The company offers a broad range of calibration and repair services for various instruments, serving businesses across the UK, particularly in the Northwest and Greater Manchester area. Their business model includes laboratory and on-site calibration, managed services, and nationwide collection and delivery. The website is professionally designed with clear navigation and good content quality, supporting their market position as an established calibration laboratory. Technically, the website employs modern frontend technologies including Bootstrap, jQuery, Font Awesome, and Google Analytics for tracking. The site is mobile-optimized and SEO-friendly, though accessibility features are basic. Security measures include HTTPS and Google reCAPTCHA, but lack visible security headers and explicit security policies. Privacy compliance is partial, with privacy and cookie policies present but no active consent mechanism. The security posture is moderate; no critical vulnerabilities or exposed sensitive data were detected, but the absence of security headers and incomplete privacy compliance are areas for improvement. The WHOIS lookup failed due to domain naming issues, which raises concerns about domain registration legitimacy despite the professional website content. Overall, the website presents a trustworthy and professional business front, but domain registration inconsistencies and some security best practices gaps suggest the need for further verification and enhancements to strengthen trust and compliance.

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

8 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

  3. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

      GDPR requires explicit consent for non-essential cookies

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

ServiceCal operates in the calibration and repair sector, targeting businesses requiring accredited instrument calibration services. Their competitive advantage lies in longstanding UKAS accreditation and comprehensive service offerings including managed services and online document access. The business model is service-oriented with a focus on quality and convenience, supported by collection and delivery logistics. The company appears to be small-sized with a regional focus but serves clients UK-wide. The website content and certifications reinforce credibility, though the lack of WHOIS transparency may affect trust. No evident partnerships or subsidiaries were identified from the data.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, and Google reCAPTCHA is implemented to protect forms, indicating awareness of basic security practices. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web attacks. No incident response or security policy information is publicly available, and privacy compliance is partial with no cookie consent mechanism. The WHOIS data failure is a notable concern, potentially indicating domain registration issues. Overall, the security posture is functional but could be significantly improved with enhanced headers, documented policies, and better privacy controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  2. Enforce HTTPS site-wide and verify SSL/TLS configuration for best practices.
  3. Add a cookie consent mechanism to comply with GDPR and enhance user privacy transparency.
  4. Publish clear security and incident response policies accessible from the website.
  5. Investigate and resolve domain registration issues to ensure WHOIS data accuracy and improve trust.

Technical notes

Notes

The website uses a modern and widely adopted frontend stack with Bootstrap and jQuery, ensuring responsive design and good user experience. Google Fonts and Font Awesome enhance visual appeal. Google Analytics and Tag Manager are used for tracking, indicating moderate user behavior analysis. Performance is moderate, with no major issues detected. Accessibility is basic and could be improved. No CMS or hosting provider details were identified. The site lacks advanced security headers and explicit privacy controls, representing technical debt in security and compliance areas.
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.
