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. 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 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

Business profile

MANDARIN operates in the technology and media sectors, offering integrated services that combine marketing, IT, and digitalization. Their business model revolves around providing comprehensive agency services, supported by specialized subsidiaries such as Sweet & Salty (content marketing), Mandarin Care (social and healthcare sector), and 2020 (sustainability consulting). The company targets medium-sized businesses and organizations looking for digital transformation and employer branding solutions. Their client portfolio includes notable brands, enhancing their market credibility. The presence of detailed service pages and a career section indicates growth orientation and talent acquisition focus. Partnerships with specialized agencies expand their service ecosystem, providing competitive advantages in niche markets.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, multiple security headers, and no visible exposure of sensitive data. The integration of a cookie consent management platform with Google Consent Mode shows compliance with privacy regulations and user consent management. However, the absence of a publicly available security policy, incident response contacts, or vulnerability disclosure mechanisms suggests room for improvement in transparency and preparedness. No known vulnerabilities or outdated libraries were detected in the analyzed scripts. Overall, the security posture is strong but could benefit from enhanced documentation and incident readiness disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly review and update third-party scripts and tracking technologies to minimize privacy risks.
  5. Enhance accessibility features further to comply with WCAG standards and improve user experience for all users.

Technical notes

Notes

The website is built using modern web technologies, primarily Next.js and React, ensuring server-side rendering and good SEO performance. The site is well-optimized for mobile devices and uses responsive images and lazy loading for performance. The presence of a GDPR-compliant cookie management system integrated with Google Consent Mode indicates advanced privacy-aware technical implementation. No major technical debts or deprecated technologies were identified. Hosting details are not explicitly disclosed, but the site uses a custom backend domain and appears to be professionally managed. Performance is fast with minimal blocking scripts and efficient resource loading. Opportunities exist to improve technical documentation and security transparency.
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.
