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

SiteOne, s.r.o. is a Czech-based digital agency specializing in design, development, and digital transformation services. The company positions itself as a stable partner for businesses seeking to translate their business goals into smart digital solutions. Their website demonstrates a professional and modern design, showcasing a strong portfolio of clients and testimonials, indicating a solid market presence in the technology sector. The company targets businesses looking for comprehensive digital solutions including web design, UX/UI, CMS and CRM integration, and technical consulting. Technically, the website employs modern JavaScript frameworks and tracking technologies such as Google Tag Manager, Google Analytics, Hotjar, and Microsoft Clarity. The site is mobile-optimized, accessible, and SEO-friendly, reflecting a mature digital infrastructure. However, the absence of WHOIS data raises questions about domain registration transparency. From a security perspective, the site uses HTTPS and implements cookie consent mechanisms, indicating awareness of privacy and security best practices. Security headers are partially observed, but explicit CSP headers and security.txt files are not detected. No vulnerabilities or exposed sensitive data were found in the content. Privacy compliance is strong with clear policies and GDPR adherence. Overall, the website presents a low-risk profile with strong business credibility and technical maturity. The main concern is the lack of WHOIS transparency, which should be addressed to enhance trustworthiness. Strategic recommendations include improving security header implementation, publishing incident response contacts, and adding vulnerability disclosure policies.

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.

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

  • Security headers: did not complete in this scan.
  • 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

SiteOne operates in the technology sector as a digital solutions provider with a focus on design and development services. Their competitive advantage lies in a comprehensive service offering, long-term client relationships, and a strong portfolio including notable clients in energy, finance, and other industries. The business model is B2B, targeting enterprises and organizations undergoing digital transformation. Revenue streams likely include project-based development, consulting, and ongoing maintenance. The company demonstrates growth through active recruitment and a visible presence in multiple languages. Partnerships and alternate domains indicate a regional expansion strategy. The company maintains a professional brand image and leverages testimonials and client logos to build trust.

Security posture

The security posture of the website is good, with HTTPS enforced and cookie consent mechanisms in place. The presence of multiple tracking and analytics tools is balanced by clear privacy policies and GDPR compliance. However, the absence of explicit security headers like Content-Security-Policy and lack of a security.txt file or incident response contact information represent gaps in security maturity. No vulnerabilities or exposed sensitive data were detected in the website content. The company should enhance transparency around security incident handling and consider publishing vulnerability disclosure policies to improve security culture and readiness.

Recommendations

  1. Implement and publish a comprehensive Content-Security-Policy header to mitigate XSS and related attacks.
  2. Create and host a security.txt file to provide clear vulnerability disclosure and incident response contacts.
  3. Publish explicit incident response and security contact information on the website.
  4. Verify and update WHOIS domain registration data to improve transparency and trust.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize tracking footprint.

Technical notes

Notes

The website uses a modern tech stack including JavaScript frameworks, SVG graphics, and integrates multiple analytics and tracking services such as Google Analytics, Hotjar, and Microsoft Clarity. The site is responsive and optimized for mobile devices, with good SEO practices including meta tags and Open Graph data. The CMS is likely Craft CMS, supported by blog references. Performance is moderate with room for optimization. No deprecated or vulnerable libraries were detected. The site architecture supports scalability and digital marketing integration. Technical risks are minimal but could be reduced by tightening security headers and improving domain registration transparency.
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.
