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

Sydney Build Expo is a major Australian construction and design trade show, hosting hundreds of exhibitors and speakers, targeting professionals across the construction industry. The website is professionally designed, content-rich, and optimized for user experience, showcasing detailed event information, speaker profiles, and networking opportunities. Technically, the site uses modern web technologies including jQuery, FontAwesome, and Google Tag Manager, with a CMS platform SHOWOFF by ASP.events. Security posture is good with HTTPS enabled and cookie consent implemented, though explicit privacy and security policies are missing. WHOIS data is unavailable, which raises some legitimacy concerns, but the site content and external partnerships suggest a legitimate business presence. Overall, the site is a credible and professional platform for the Sydney Build Expo event.

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

4 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 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

  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

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 Sydney Build Expo operates as an event organizer in the construction and real estate sector, focusing on large-scale trade shows and conferences. It targets a broad audience of contractors, architects, engineers, developers, and government officials. The business model centers on exhibition space sales, sponsorships, and conference participation. The site promotes related events such as Melbourne Build Expo, indicating a partnership ecosystem. The company positions itself as a market leader in Australia for construction industry events, leveraging extensive speaker lineups and networking opportunities to attract attendees and exhibitors.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and a cookie consent mechanism in place. However, the absence of visible security headers such as Content-Security-Policy and Strict-Transport-Security reduces the overall security robustness. No incident response or vulnerability disclosure information is provided, which could hinder rapid response to security issues. The use of multiple third-party scripts and tracking pixels introduces potential risk vectors that require ongoing monitoring. The lack of WHOIS transparency is a concern but may be due to privacy protection. Overall, the site is secure for general use but could improve transparency and technical security controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to enhance legal compliance and user trust.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to improve protection against common web attacks.
  4. Provide clear incident response contact information to improve security incident handling and transparency.
  5. Regularly audit and update third-party scripts to minimize vulnerabilities and ensure compliance with privacy regulations.

Technical notes

Notes

The website is built on the SHOWOFF CMS platform by ASP.events, utilizing jQuery, FontAwesome, and bxSlider for UI components. It integrates Google Tag Manager and Facebook Pixel for analytics and marketing. The site is mobile responsive with good accessibility features and SEO optimization. Performance is moderate, with multiple external resources loaded from CDN providers. The site lacks some modern security headers and explicit privacy/legal pages, which are technical debt areas. Hosting provider details are not evident from the data. Overall, the technical infrastructure supports a professional event site but could benefit from enhanced security and privacy implementations.
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.
