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

Sigma Group is a UK-based company specializing in retail and commercial estate solutions, offering integrated services across logistics, display, project solutions, and building services. With over 20 years of experience, the company serves major domestic and international brands, positioning itself as a trusted partner in the retail sector. Their business model focuses on turnkey solutions with in-house capabilities, supporting multi-site transformations and sustainability initiatives. The website reflects a professional and consistent brand image, targeting retail and commercial operators seeking scalable and expert-led services. Technically, the website is built on WordPress with modern plugins and libraries such as WPBakery, Contact Form 7, and Google Analytics. The infrastructure is moderately performant and mobile-optimized, with good SEO practices and accessibility features. Hosting and domain registration are consistent with the company's UK base, and the domain age aligns with the company's claimed history. From a security perspective, the site uses HTTPS with good SSL configuration but lacks explicit security headers and dedicated security or incident response policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is partially addressed with privacy and cookie policies, though no active cookie consent mechanism is present. Contact information is clear, but no dedicated security contact channels or data protection officer details are found. Overall, the website presents a low-risk profile with strong business credibility and professional digital presence. Strategic improvements in security policy transparency, cookie consent, and security headers would enhance the security posture and compliance standing.

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

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

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 29 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

  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 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 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

Sigma Group operates in the retail and commercial solutions sector, leveraging over two decades of experience to serve major UK and international brands. Their competitive advantage lies in integrated service delivery across multiple business units, including display manufacturing, logistics management, project solutions, and building services. The company targets retail chains, commercial estate operators, and sectors requiring large-scale fit-outs and refurbishments. Growth indicators include international warehouse operations and a broad client portfolio featuring leading retailers. The company emphasizes sustainability and technical expertise, supporting clients' net-zero goals and energy optimization. Their partnership ecosystem includes major retail brands, though no explicit partner domains were identified. The business model is service-oriented, focusing on turnkey solutions with accountability and quality control.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. No explicit security or incident response policies are published, and no dedicated security contact channels are provided. The use of well-known WordPress plugins suggests standard security practices, but the lack of cookie consent mechanisms and vulnerability disclosure policies indicates room for improvement in compliance and transparency. Overall, the security maturity is moderate, with no critical vulnerabilities detected but lacking advanced security controls and documentation.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page including contact channels for reporting security issues.
  3. Add a cookie consent mechanism to comply fully with GDPR and ePrivacy Directive requirements.
  4. Conduct an accessibility audit and improve features to meet WCAG standards for better inclusivity.
  5. Regularly review and update plugins and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website is built on a modern WordPress platform using current versions of plugins and libraries, including WPBakery Page Builder and Contact Form 7. It employs Google Fonts and FontAwesome for styling and icons, and integrates Google Analytics for user tracking. The site is responsive and mobile-optimized with a clean, professional design. Performance is moderate, with potential improvements in caching and asset optimization. The technical stack is standard for corporate websites, with no legacy or deprecated technologies detected. The infrastructure is hosted under a reputable UK registrar, supporting the company's geographic claims. Technical risks are low but could be further reduced by implementing security headers and improving privacy compliance mechanisms.
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.
