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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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 a multi-city event ecosystem with a diversified business model centered on event hosting, ticket sales, and value-added membership services. Its market position is strong within China, supported by official business licenses and ICP registrations. The platform leverages multiple subdomains for specialized services such as event posting, user management, and trade, indicating a modular and scalable infrastructure. Partnerships with regional platforms and advertising collaborations further enhance its market reach. The absence of WHOIS data is a minor concern but does not detract significantly from its operational legitimacy.

Security posture

The website enforces HTTPS, ensuring encrypted communications, and avoids exposing sensitive data in its HTML content. However, it lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could improve protection against common web attacks. No vulnerable or outdated libraries were detected in the frontend stack. The absence of a cookie consent mechanism and explicit privacy compliance features suggests room for improvement in regulatory adherence. Incident response and security policy disclosures are not present, indicating potential gaps in transparency and readiness.

Recommendations

  1. Implement comprehensive security headers to enhance protection against XSS, clickjacking, and other web threats.
  2. Introduce a clear cookie consent banner and privacy compliance mechanisms to align with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Regularly audit and update third-party libraries and dependencies to mitigate vulnerabilities.
  5. Enhance accessibility features to improve usability for all users, including those with disabilities.

Technical notes

Notes

The website utilizes a modern frontend technology stack including Vue.js, Axios, Swiper.js, and jQuery, indicating a mature and interactive user experience. The modular use of multiple subdomains for different services suggests a well-architected backend infrastructure. Performance is moderate with good mobile optimization, though accessibility could be improved. SEO practices are evident with proper meta tags and structured navigation. The lack of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicitly available from the HTML content.
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.
