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

5 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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

  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"

    • 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';…

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

The company positions itself as a niche consultancy with a global footprint in environmental and climate adaptation sectors. Their business model focuses on consulting and project execution funded by international and governmental clients. The presence of detailed project portfolios and testimonials suggests a strong reputation and client trust. The limited social media presence (LinkedIn only) aligns with a professional B2B focus. The website's content and structure support lead generation and client engagement through contact forms and downloadable materials.

Security posture

The website demonstrates a good security baseline with enforced HTTPS, secure contact forms with user consent, and a detailed cookie consent mechanism compliant with GDPR. However, the absence of published security policies, incident response contacts, and security headers indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable plugins and hosting provider further supports a secure environment. Implementing additional security headers and publishing formal policies would enhance trust and compliance.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Include explicit contact information such as phone numbers and physical addresses to improve business credibility.
  5. Regularly audit and update WordPress plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress with a modern tech stack including jQuery, Revolution Slider, Contact Form 7, and GoodLayers Core plugin. Hosting is provided by a reputable UK registrar and hosting company (LCN). The site is mobile optimized with responsive design and good SEO practices including meta tags and structured data (JSON-LD). Performance is moderate, with some heavy slider elements but overall acceptable. Accessibility is basic but could be improved with enhanced ARIA roles and keyboard navigation support. The cookie consent implementation is robust and user-friendly.
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.
