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

Blocksil is a UK-based company specializing in advanced, sustainable coating innovations serving a broad range of industrial and commercial sectors. Their website presents a professional image with detailed sector-specific solutions and a comprehensive menu structure highlighting their expertise, services, and product offerings. The company targets B2B clients requiring specialized coatings and consultancy services. Technically, the site is built on WordPress using popular plugins and frameworks, with moderate performance and good mobile optimization. Security measures include HTTPS and Google reCAPTCHA, but lack of security headers and privacy policies indicate room for improvement. The WHOIS data raises concerns due to an inconsistent future domain creation date, which impacts trustworthiness. Overall, the site is functional and professional but would benefit from enhanced privacy compliance and security hardening.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  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

Blocksil occupies a niche market in manufacturing coatings with a focus on innovation and sustainability. Their business model includes product supply, consultancy, application support, and training, targeting sectors such as construction, transportation, municipal, and utilities. The presence of case studies, testimonials, and patents suggests a credible market position. The company appears small but established since 2017, with a global reach implied by their worldwide page. The website's detailed sector and solution menus indicate a well-structured approach to customer segmentation and service delivery. However, the lack of explicit business contact details and inconsistent WHOIS data suggest the need for improved transparency to strengthen business credibility.

Security posture

The website employs HTTPS and integrates Google reCAPTCHA to protect forms, indicating basic security awareness. However, the absence of key security headers (CSP, HSTS, X-Frame-Options) and no visible incident response or vulnerability disclosure policies highlight gaps in security maturity. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site lacks privacy and cookie policies, which are critical for GDPR compliance. Overall, the security posture is moderate but requires enhancements in policy publication, header implementation, and compliance documentation to reduce risk and improve trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit GDPR compliance and consent mechanisms.
  2. Add security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to harden the site against common attacks.
  3. Publish an incident response plan and vulnerability disclosure policy to demonstrate security readiness and transparency.
  4. Verify and correct WHOIS domain registration data to remove inconsistencies and improve domain trustworthiness.
  5. Enhance accessibility features and conduct regular security audits of third-party plugins to maintain a secure and compliant environment.

Technical notes

Notes

The website is built on WordPress with a modern tech stack including jQuery, FontAwesome, and LayerSlider. It uses advanced menu plugins like UberMenu and user management via Ultimate Member. The site loads moderate resources and is mobile optimized with responsive design. However, some lazy loading scripts have errors (e.g., 'v1ideo' typo) which could affect media loading. Performance is moderate with room for optimization. The hosting provider is Namecheap via reseller Spaceship. SEO is supported by proper meta tags and JSON-LD structured data. Technical risks include outdated or misconfigured plugins and missing security headers. Modernization opportunities include fixing script errors, improving accessibility, and enhancing 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.
