COSO Architecture · Real Estate · Australia

Medium risk. 7 critical or high findings in Security headers and GDPR outside view.

Security score

66/100

Risk levelMedium

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

COSO Architecture is a small architectural firm based in Sydney, Australia, providing professional architectural and design services. The website presents a professional and well-structured digital presence built on WordPress with modern technologies such as WPBakery Page Builder and Google Analytics integration. The technical infrastructure is moderate in performance and mobile optimization, with hosting likely provided by Netregistry. Security posture is adequate with HTTPS enabled but lacks important security headers and privacy compliance mechanisms such as cookie consent and privacy policies. No explicit contact information or incident response details are present, which limits user trust and compliance with data protection regulations. Overall, the website is functional and professional but requires improvements in privacy compliance and security best practices to enhance trust and regulatory adherence.

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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

COSO Architecture operates in the real estate sector focusing on architectural services in the Sydney and broader Australian market. The business model is service-oriented, targeting individuals and businesses seeking architectural design and consultation. The website content and branding are consistent and relevant to the industry, but lack explicit trust signals such as certifications or client testimonials. The firm appears to be a small-sized entity with no parent or subsidiary companies indicated. The digital presence is standard for a professional services firm but could benefit from enhanced transparency and contact accessibility to improve client engagement and credibility.

Security posture

The website employs HTTPS ensuring encrypted communication, which is a fundamental security requirement. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the defense-in-depth posture. No evidence of vulnerable libraries or exposed sensitive data was found in the analyzed content. The lack of privacy and cookie policies, as well as incident response or vulnerability disclosure information, indicates gaps in compliance and security governance. The site uses common third-party scripts such as Google Analytics and Tag Manager, which require proper privacy disclosures. Overall, the security maturity is moderate but needs enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR and other privacy laws.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to improve security posture.
  3. Publish clear contact information including emails and phone numbers to enhance business credibility and user trust.
  4. Establish and publish an incident response plan and vulnerability disclosure policy to demonstrate security readiness.
  5. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing attacks.

Technical notes

Notes

The website is built on WordPress CMS using WPBakery Page Builder, with jQuery and Google Analytics scripts included. The hosting provider is likely Netregistry based on DNS nameservers. The site is mobile optimized and uses modern CSS and HTML5 standards. Performance is moderate with asynchronous loading of analytics scripts. No critical technical debt or deprecated technologies were detected. However, the absence of security headers and privacy compliance features indicates areas for modernization. The site would benefit from enhanced accessibility features and SEO optimizations to improve reach and usability.
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.
