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

Marketlayer Limited is a London-based email marketing company specializing in data-driven email marketing solutions for B2B and B2C clients. The company offers a comprehensive suite of services including campaign growth, segmentation, fully managed campaigns, pixel-perfect design, A/B testing, and detailed reporting. Marketlayer positions itself as one of the fastest-growing email broadcasting and digital marketing firms in London, targeting businesses seeking to enhance their email marketing effectiveness. Technically, the website employs modern web technologies such as Bootstrap, Font Awesome, jQuery, React (development scripts), and Google Tag Manager for analytics. The site is mobile-optimized with good SEO practices and uses HTTPS with Google reCAPTCHA for bot protection. However, some security best practices like security headers and explicit cookie consent mechanisms are missing. From a security perspective, the site demonstrates a solid baseline with HTTPS and bot protection but lacks visible security headers and incident response information. The absence of WHOIS registration data for the domain is a notable concern, potentially impacting trust and legitimacy perceptions. The site displays certifications such as Cyber Essentials and Living Wage Employer badges, enhancing credibility. Overall, Marketlayer presents a professional and trustworthy front with strong business and technical foundations but should address WHOIS registration transparency and enhance privacy and security policies to improve compliance and trustworthiness.

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. 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

  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"

      • 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';…

  3. 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

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

Marketlayer operates in the digital marketing sector focusing on email marketing services. Its competitive advantage lies in its data-driven approach and comprehensive service offerings tailored for both B2B and B2C clients. The company leverages certifications and social proof to build trust. Revenue streams likely include service contracts for email campaign management and consulting. The target market is UK-based businesses seeking to improve email marketing ROI. The company maintains active social media channels and uses modern marketing tools, indicating a growth-oriented strategy. However, the unclear domain registration status could pose risks to reputation and customer confidence.

Security posture

The website's security posture is moderate to good. HTTPS is enforced, and Google reCAPTCHA is implemented to mitigate automated abuse. However, the absence of key security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces the overall security robustness. No incident response or security policy pages are found, which limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the HTML content. Privacy compliance is partial, with privacy and GDPR policies present but lacking explicit cookie consent mechanisms. The missing WHOIS data raises concerns about domain legitimacy and ownership transparency, which is a critical trust factor.

Recommendations

  1. Register the domain properly and ensure WHOIS data is publicly available and accurate to improve trust and legitimacy.
  2. Implement and configure essential security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  3. Add a clear cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  4. Publish explicit security policies and incident response contact information to improve transparency and readiness.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern and popular technology stack including Bootstrap for responsive design, Font Awesome for icons, jQuery for DOM manipulation, and React with Vite for development. Google Tag Manager and Facebook SDK are used for analytics and marketing. The site is served over HTTPS, ensuring encrypted communication. Performance is moderate with room for optimization. The site is mobile-friendly and SEO optimized with proper meta tags and structured data. However, the lack of a CMS suggests a custom or static site approach. No hosting provider information was detected. The site could benefit from improved security headers and 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.
