0–100, higher is better. How it is calculated

Nagoya International Exhibition Hall (ポートメッセなごや) operates as a major international exhibition and event venue located in Nagoya, Japan. The facility caters to a broad range of events including seminars, business meetings, exhibitions, ceremonies, parties, incentives, concerts, and other communication spaces. It serves event organizers and visitors primarily in the hospitality and government sectors, positioning itself as a key regional player in event hosting and venue services. Technically, the website is built on WordPress 4.9.9 with a variety of plugins such as Contact Form 7 for forms, Smart Slider 3 for visual content, and FooBox for image lightbox functionality. The site uses jQuery and jQuery UI libraries and integrates Google Tag Manager for analytics and marketing. The site is mobile optimized and includes accessibility features, but the WordPress version is outdated, which may pose security risks. From a security perspective, the site enforces HTTPS and uses Google Tag Manager and reCAPTCHA on forms, but lacks comprehensive security headers and runs an outdated CMS version. No explicit security or incident response policies are published. Privacy compliance is basic with a privacy policy present but no cookie consent mechanism detected. Overall, the website is professional and trustworthy with good business credibility and content quality. However, security and privacy compliance could be improved by updating software, adding security headers, and implementing cookie consent mechanisms.

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

6 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
    • 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 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

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

  • Network security: did not complete in this scan.
  • 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 business operates a large-scale international exhibition hall in Nagoya, Japan, targeting event organizers and attendees across various sectors. Its business model focuses on venue rental and event support services, including catering and hospitality partnerships. The company maintains a broad partner ecosystem, as evidenced by numerous linked partner domains in hospitality, catering, security, and accommodation. The website content is regularly updated with event information and news, indicating active operations and engagement with its audience. The lack of detailed corporate registration or founding year suggests a focus on venue services rather than corporate branding online.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and use of Google Tag Manager and reCAPTCHA for user interaction tracking and form protection. However, the WordPress core version is outdated (4.9.9), which may expose the site to known vulnerabilities. Security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, reducing protection against common web attacks. No published security policy or incident response contact information is available, indicating limited transparency in security governance. The site should prioritize CMS and plugin updates, implement security headers, and publish security policies to enhance trust and compliance.

Recommendations

  1. Update WordPress core and all plugins to the latest stable versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner and explicit cookie policy to improve privacy compliance and GDPR readiness.
  4. Publish a security policy and incident response contact information to increase transparency and preparedness.
  5. Conduct regular security audits and vulnerability scans to proactively identify and remediate risks.

Technical notes

Notes

The website uses a mature WordPress CMS platform with a variety of plugins for event management, forms, sliders, and accessibility. The tech stack includes jQuery, jQuery UI, Smart Slider 3, Font Awesome, and Contact Form 7. The site loads external resources from Google APIs and social media platforms. Performance is moderate with some modern features like responsive design and accessibility enhancements. However, the WordPress version is outdated, which introduces technical debt and security risks. The site could benefit from modernization efforts including updating the CMS, optimizing resource loading, and enhancing security configurations.
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.
