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

BuiltWith® Pty Ltd is an established Australian technology company specializing in website technology profiling and analytics services since 2007. The company targets technology professionals, developers, and marketers by providing detailed insights into website technology stacks and market trends. Their business model is primarily SaaS-based, offering data-driven intelligence to support digital strategy and competitive analysis. Technically, the website leverages modern frameworks such as Bootstrap and Google Fonts, hosted on Amazon AWS infrastructure. However, the current website content is inaccessible due to IP blocking by AWS WAF security rules, which limits the ability to fully assess performance, SEO, and user experience. The domain is well-registered with consistent WHOIS data and uses AWS DNS services, indicating a stable technical foundation. From a security perspective, the site benefits from AWS WAF protections but lacks visible security headers and publicly available security policies. The blocking of IP addresses suggests active threat mitigation but also risks blocking legitimate users. No privacy or cookie policies were found, and contact information is limited to a physical address, reducing transparency and compliance confidence. Overall, the website's risk profile is elevated due to content inaccessibility and lack of visible compliance documentation. Strategic recommendations include enabling DNSSEC, publishing privacy and security policies, improving security header implementation, and reviewing WAF rules to reduce false positives and improve user access.

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

8 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

BuiltWith operates in the technology sector with a focus on website technology profiling and analytics. The company holds a medium market size with a solid foundation since 2007. Its competitive advantage lies in providing detailed technology stack data and market intelligence to digital professionals. Revenue streams likely include subscription services and data access fees. The target customers are developers, marketers, and analysts seeking technology insights. The company maintains a professional presence with a registered Australian entity and physical office address. Partnerships or subsidiaries were not identified in the provided data. Growth indicators are limited due to blocked content, but the long domain age suggests sustained operations.

Security posture

The security posture shows moderate maturity with AWS WAF actively blocking suspicious IPs, indicating proactive threat management. However, the absence of visible security headers, lack of published security or incident response policies, and no contact channels for security incidents reduce transparency and readiness. The domain uses clientTransferProhibited status to prevent unauthorized transfers, which is a positive control. DNSSEC is not enabled, representing a potential DNS security gap. No vulnerabilities or exposed sensitive data were detected in the limited content. Overall, the security posture is functional but could benefit from enhanced policy publication and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and integrity.
  2. Publish comprehensive privacy, cookie, and security policies to enhance compliance and user trust.
  3. Implement standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Review and fine-tune AWS WAF rules to minimize false positives and avoid blocking legitimate users.
  5. Establish and publicize incident response contact channels to improve security transparency and readiness.

Technical notes

Notes

The website uses Bootstrap 4.3.1 and Google Fonts for UI styling, hosted on Amazon AWS infrastructure with multiple AWS DNS servers. The domain registration is stable with a long expiry date and clientTransferProhibited status. The site lacks DNSSEC and visible security headers. Performance and SEO cannot be fully assessed due to content blocking. Mobile optimization and accessibility appear basic based on CSS and meta viewport tags. No CMS or advanced frameworks were detected. External resources are loaded from trusted CDNs. The site is currently inaccessible due to AWS WAF blocking IP addresses, limiting further technical evaluation.
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.
