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

4 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 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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

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 operates in the finance sector, focusing on exclusive investment management and family office services. Its market position is niche and selective, targeting high-net-worth clients. The business model is service-oriented with a focus on personalized investment management rather than broad platform trading. The website content and structure support this exclusivity, with clear legal and privacy documentation and direct contact channels. The company maintains a consistent brand image and has a long domain history, enhancing trust. Partnerships include a web development firm, Blue Whale Media. No signs of aggressive marketing or advertising are present, aligning with the firm's selective client approach.

Security posture

The website enforces HTTPS and uses secure form submission for login. Password strength is actively checked using the zxcvbn library. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security posture. No incident response or security policy information is provided, which could be improved to enhance transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site does not appear to use tracking or advertising scripts that could introduce privacy risks. Overall, the security maturity is moderate with room for improvement in headers and incident response visibility.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to harden the site against common web attacks.
  2. Add a visible security or incident response policy page with dedicated contact channels such as security@ or abuse@ emails to improve transparency and readiness.
  3. Introduce a cookie consent mechanism to comply fully with GDPR and enhance user privacy controls.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities and maintain security hygiene.
  5. Enhance accessibility features and SEO optimization to improve user experience and search engine visibility.

Technical notes

Notes

The website is built on a WordPress CMS platform using Themify Builder and jQuery libraries, hosted by Ionos SE. It employs modern JavaScript libraries for password strength validation and UI enhancements. The site loads external resources from reputable CDNs and uses a custom theme with consistent branding. Performance is moderate with no major issues detected, and mobile optimization is good. Accessibility is basic but could be improved. SEO practices are present but minimal, with meta tags and structured navigation. The technical infrastructure is stable but would benefit from enhanced security headers and privacy mechanisms to align with best practices.
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.
