Their platform enables manufacturers and sellers in sectors such as steel buildings, roofs, storage systems, and modular construction to streamline sales processes, generate leads online, and automate quote generation. The company positions itself as a niche technology provider offering innovative and customizable solutions to improve efficiency and customer engagement. Technically, the website is built on modern web technologies including Webflow CMS, JavaScript frameworks, and integrates third-party services such as Google Tag Manager, Calendly, and Tidio chat. The site is well-optimized for performance, mobile responsiveness, and accessibility, with a professional design and clear navigation. Security measures include HTTPS enforcement and bot protection via Cloudflare Turnstile captcha, alongside cookie consent mechanisms ensuring GDPR compliance. While the website demonstrates strong security best practices and privacy compliance, the absence of publicly available WHOIS data for the domain www.histruct.com introduces some uncertainty regarding domain registration legitimacy.

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

5 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 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 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 28 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

HiStruct operates in a specialized segment of the construction technology market, focusing on SaaS solutions for 3D configurators that enhance sales and project management workflows. Their competitive advantage lies in offering customizable, web-based tools that reduce manual quoting efforts and improve customer interaction through realistic 3D models and AR/VR capabilities. The business model leverages direct sales and online lead generation, targeting manufacturers and sellers of construction-related products. The presence of multiple language subdomains indicates an international market approach. Partnerships with known clients and integration with popular tools like Calendly and Tidio suggest a growing ecosystem. The company’s small size and focused product suite position it as an agile player with potential for expansion in the digital construction tools market.

Security posture

The website exhibits a mature security posture with HTTPS enforced and use of Cloudflare Turnstile captcha to mitigate automated abuse. Cookie consent is implemented, supporting GDPR compliance. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not clearly detected in the HTML source, representing an area for improvement. No signs of exposed credentials, vulnerable libraries, or insecure forms were found. The lack of a published security policy or incident response page limits transparency. Overall, the security measures are adequate for the business type but could be enhanced by adopting additional HTTP headers and publishing formal security documentation.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response page to improve transparency and customer trust.
  3. Add a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility compliance to meet or exceed WCAG standards, improving usability for all users.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries including jQuery 3.5.1 and various third-party integrations such as Google Tag Manager for analytics, Calendly for scheduling, and Tidio for live chat support. Hosting and CDN services appear to be provided by Cloudflare, inferred from Turnstile captcha usage and CDN URLs. The site demonstrates fast loading times, mobile optimization, and good SEO practices with proper meta tags and Open Graph data. The multilingual support is implemented via subdomains and a language redirection script. The technical stack is modern and well-maintained, with opportunities to improve security headers and formalize security documentation.
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.
