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

Gremmo Homes is a medium-sized Australian company specializing in luxury custom home building and design services primarily serving the Sydney metropolitan area. The company emphasizes unique, functional, and individually tailored homes with over 30 years of experience, positioning itself as an established player in the real estate and home construction market. The website showcases a professional portfolio of projects and testimonials, reinforcing its market presence. Technically, the website is built on WordPress using Elementor and Yoast SEO, indicating a modern and maintainable infrastructure. The site is mobile-optimized and provides a good user experience with clear navigation and quality content. Security posture is adequate with HTTPS enabled, but lacks advanced security headers and formal privacy or cookie policies, which are areas for improvement. The WHOIS data is limited due to privacy protection, but the domain appears legitimate and consistent with the business claims. Overall, the website is professional and trustworthy but would benefit from enhanced privacy compliance and security best practices.

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

11 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. 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"

      • 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"

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 · found on this site
  • 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 targets affluent home buyers and property owners in Sydney seeking bespoke luxury homes. Its business model revolves around custom home design and construction, complemented by interior design and outdoor living solutions. The presence of awards and testimonials suggests a competitive advantage in quality and customer satisfaction. The company maintains a portfolio of projects highlighting its craftsmanship and design capabilities. There is no evidence of partnerships or subsidiaries from the website data. Revenue streams likely derive from direct client contracts for home building and design services. The company’s digital presence is focused and consistent, though lacking in transparency regarding privacy and contact details.

Security posture

The website employs HTTPS, ensuring encrypted communications, which is a fundamental security measure. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks like clickjacking and MIME sniffing. No incident response or security policy information is available, indicating limited transparency in security governance. The lack of visible privacy and cookie policies suggests potential compliance gaps with GDPR and other privacy regulations. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, formal policies, and contact channels for security incidents.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish contact information including company emails and phone numbers to improve business credibility and user trust.
  4. Establish and publish a security policy and incident response contact channels to demonstrate security maturity.
  5. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities and maintain performance.

Technical notes

Notes

The website is built on a WordPress CMS platform using the Elementor page builder and Yoast SEO plugin, indicating a modern and widely supported technology stack. It uses jQuery and Swiper.js for interactive elements such as sliders and carousels. The site is responsive and optimized for mobile devices, with appropriate meta tags and SEO configurations. Performance appears moderate, with large images used but likely optimized for web delivery. Accessibility features are basic but present. No advanced hosting or CDN information was detected. The technical implementation supports a good user experience but could benefit from enhanced security configurations and privacy compliance mechanisms.
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.
