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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Synology holds a strong market position as a leading provider of NAS and data management solutions with a global footprint. Its competitive advantages include a comprehensive product portfolio, strong security posture, and a focus on customer trust through transparent policies and programs. The business model revolves around hardware sales complemented by cloud services and software solutions, targeting enterprises, SMBs, and individual consumers. Growth indicators include continuous product innovation, expansion into cloud and AI-integrated services, and active engagement in security research via bounty programs. The partnership ecosystem includes technology partners and integrated solutions, enhancing market reach and product integration.

Security posture

Synology exhibits a mature security posture with multiple layers of protection and transparency. The presence of a secure development lifecycle, supply chain risk management, and a public security advisory page indicates proactive risk management. HTTPS and security headers are properly implemented, and cookie consent mechanisms support privacy compliance. The bounty program encourages responsible vulnerability disclosure. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a security.txt file and explicit Data Protection Officer contact are minor gaps. Overall, the security culture appears strong and business-aligned.

Recommendations

  1. Publish a security.txt file to streamline vulnerability reporting and improve transparency.
  2. Explicitly disclose Data Protection Officer contact information to enhance GDPR compliance.
  3. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  4. Enhance data retention policy disclosures related to analytics and user data.
  5. Continue expanding security awareness and training programs to maintain strong security culture.

Technical notes

Notes

The website is built on a modern technology stack featuring Vue.js and jQuery, supported by Google Tag Manager and LiveChat for analytics and customer interaction. The site demonstrates fast loading times, responsive design, and good accessibility features. SEO is well-implemented with comprehensive meta tags and structured data. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not explicitly available but performance and security configurations indicate a professional hosting environment. Opportunities exist to further modernize by adopting newer frameworks or enhancing automation in deployment and security scanning.
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.
