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

Antleaf Ltd. is a specialized digital consultancy operating primarily in the higher-education and research sectors. The company focuses on scholarly communications, repositories, data and metadata management, and web system design and development. Their market position is that of a niche expert consultancy serving academic and research institutions with tailored technical and project management services. The website reflects a small but professional business with clear branding and a consistent message aligned with their domain expertise. Technically, the website is built using the Hugo static site generator, leveraging Bootstrap for responsive design and Google Fonts for typography. The site is hosted with DNS managed by Cloudflare and uses Plausible Analytics for privacy-conscious visitor tracking. The technical implementation is modern and performant, with good mobile optimization and SEO practices, though accessibility features are basic. From a security perspective, the site uses HTTPS and Cloudflare DNS but lacks DNSSEC and visible security headers, which are recommended for enhanced protection. No privacy or cookie policies are published, representing a compliance gap especially relevant under GDPR. No incident response or vulnerability disclosure information is provided. The WHOIS data is consistent and trustworthy, with domain registration dating back to 2012, matching the company's founding timeline. Overall, the website is professional and trustworthy but would benefit from improved privacy compliance and enhanced security headers. The risk level is moderate with no critical vulnerabilities detected, but compliance improvements are advised.

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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. 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

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Antleaf Ltd. operates in a specialized niche within the education sector, providing consultancy and technical development services focused on scholarly communications and research infrastructure. Their competitive advantage lies in deep domain expertise and a focused service offering. The business model is service-based consultancy with project and service management capabilities. The company targets higher education institutions, research organizations, and related infrastructure providers. Growth indicators include a stable domain presence since 2012 and a broad client and collaborator network showcased on the website. Partnerships appear to be academic and research-focused, enhancing credibility. Revenue streams likely derive from consultancy contracts and technical development projects. The company maintains a small size with a UK base, emphasizing quality and specialization over scale.

Security posture

The current security posture is moderate. The website uses HTTPS and Cloudflare DNS, which provides a baseline of security. However, the absence of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security hardening. No forms or input fields are present on the homepage, minimizing attack surface. There is no published security policy, incident response plan, or vulnerability disclosure mechanism, which are important for transparency and readiness. Privacy compliance is weak due to missing privacy and cookie policies. The WHOIS data is consistent and stable, supporting legitimacy. Overall, the site is secure enough for its purpose but should implement recommended security headers and publish compliance documentation to improve trust and reduce risk.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  4. Add a security policy page including incident response and vulnerability disclosure information.
  5. Regularly review and update technical dependencies and monitor for vulnerabilities.

Technical notes

Notes

The website is built using the Hugo static site generator, which provides fast and secure static content delivery. Bootstrap framework is used for responsive design, and Google Fonts enhance typography. Analytics are handled by Plausible, a privacy-focused service. DNS is managed via Cloudflare, but DNSSEC is not enabled, which is a missed opportunity for enhanced DNS security. The site loads CSS and JS assets efficiently, but no explicit performance metrics are available. Accessibility is basic, with room for improvement in ARIA roles and semantic HTML. SEO is good with proper meta tags and structured navigation. Overall, the technical infrastructure is modern and well-maintained but could benefit from additional security hardening and accessibility enhancements.
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.
