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

Zola is a medium-sized company specializing in the design, manufacture, and supply of high-performance European-style windows and doors, primarily serving the North American market. Their product range includes clad wood, aluminum, uPVC, and wood frames with various configurations such as tilt & turn, fixed, and folding walls. The company positions itself as a leader in Passive House certified windows, emphasizing architectural freedom, comfort, and energy efficiency. The website is professionally designed, content-rich, and targets architects, builders, and homeowners seeking premium window solutions. Technically, the website is built on the Webflow platform, leveraging modern web technologies and multiple analytics and marketing tools including Google Analytics, Facebook Pixel, LinkedIn Insight Tag, and Bing UET. The site is mobile optimized and performs moderately well, though there is room for improvement in accessibility and SEO. Security-wise, the site uses HTTPS but lacks visible security headers and formal privacy or cookie policies, which are critical for compliance and user trust. The WHOIS data for the domain is missing or unavailable, which raises concerns about domain legitimacy despite the professional online presence. No contact emails or phone numbers are explicitly provided on the site, limiting direct communication channels. Social media presence is confirmed on Instagram and Facebook. Overall, the site demonstrates a solid business and technical foundation but requires enhancements in privacy compliance, security best practices, and transparency to improve 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

5 findings rated critical or high. Fix these first.

  1. 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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

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

Zola operates in the real estate sector focusing on premium window and door manufacturing with a strong emphasis on energy efficiency and architectural design. Their competitive advantage lies in their extensive customization options and leadership in Passive House certified products. The business model combines manufacturing with direct customer engagement through showrooms, idea books, and online resources. Revenue streams likely include product sales, customization services, and installation support. The target customers are architects, builders, and discerning homeowners across North America. The company demonstrates growth potential through its niche market positioning and employee-owned structure, fostering dedication and quality. Partnerships with design and construction firms are implied through project credits and testimonials. Strategic observations suggest a need to enhance digital trust signals and compliance documentation to support market expansion.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. The lack of privacy and cookie policies indicates compliance gaps with GDPR and other privacy regulations. No incident response or vulnerability disclosure information is provided, limiting transparency and readiness for security events. The use of multiple third-party tracking scripts increases the attack surface and necessitates regular security audits. Overall, while basic security measures are in place, significant improvements are needed in policy transparency, header implementation, and incident preparedness to align with best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear consent mechanisms to ensure GDPR and global privacy compliance.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against web vulnerabilities.
  3. Publish incident response and vulnerability disclosure information including security contact emails to improve transparency and readiness.
  4. Provide clear company contact information including verified emails and phone numbers to enhance trust and customer support.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks and ensure compliance with privacy standards.

Technical notes

Notes

The website is built on the Webflow platform, utilizing modern front-end technologies including jQuery and WebFont Loader. It integrates multiple analytics and marketing tools such as Google Analytics, Facebook Pixel, LinkedIn Insight Tag, and Bing UET, indicating a mature digital marketing strategy. The site loads moderately fast and is mobile optimized with good design quality and navigation clarity. However, the absence of security headers and privacy policies suggests technical debt in security and compliance areas. The WHOIS data absence is a technical anomaly that could impact domain reputation. Opportunities exist to improve accessibility features and SEO optimization further. Overall, the technical infrastructure supports a professional online presence but requires enhancements in security and compliance to reduce operational risks.
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.
