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

2 findings rated critical or high. Fix these first.

  1. 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

  2. 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

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.

Security posture

Synology exhibits a mature security posture with enforced HTTPS, comprehensive privacy and cookie policies, and a public security advisory and bounty program. The website does not expose sensitive information or vulnerable libraries. However, explicit HTTP security headers were not detected in the provided data, suggesting room for improvement. Incident response readiness is indicated by the presence of a bounty program and security advisories. Compliance with GDPR is evident through privacy statements and cookie consent mechanisms. Overall, the security culture appears proactive, with clear communication channels for vulnerability reporting and data protection.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Enhance accessibility features to meet WCAG standards for improved user experience and compliance.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Expand incident response documentation and provide direct security contact emails to improve transparency and responsiveness.

Technical notes

Notes

The website uses a modern technology stack including Vue.js for reactive UI components and jQuery for DOM manipulation. Google Tag Manager is used for analytics and marketing tags, and LiveChat provides customer support integration. The site is served over HTTPS with canonical URLs properly set. CSS and JavaScript assets are versioned for cache management. The site demonstrates good mobile optimization and responsive design. However, no CMS was explicitly detected, suggesting a custom or proprietary platform. Performance appears moderate with room for optimization in loading times and accessibility compliance. The technical infrastructure supports a professional and scalable web presence suitable for a global technology company.
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.
