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

Optik Studio Jana Čížková s.r.o. is a small retail optical business based in the Czech Republic, specializing in the sale of branded eyewear and providing expert optical services. The website presents a professional and consistent brand image, targeting consumers seeking quality eyeglasses and optical care in Prague. The company maintains an active blog and social media presence, enhancing customer engagement. Technically, the website is built on the Webnode CMS platform, hosted via Amazon Cloudfront CDN, and employs modern web technologies including Google Analytics and Tag Manager for tracking. The site is mobile-optimized and performs moderately well, with good SEO practices in place. Security-wise, the site uses HTTPS with a valid SSL certificate and implements a cookie consent banner, but lacks advanced security headers and explicit privacy or security policies. WHOIS data is unavailable due to privacy protection, which is common and justified for this business type. Overall, the website is trustworthy and functional but could improve in privacy transparency and security hardening.

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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  3. 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

The company operates in the retail sector focusing on eyewear and optical services, offering a wide range of premium brands. Its business model is direct retail with a local market focus in Prague. The website content and blog indicate active marketing and customer engagement efforts. The company is registered officially with Czech authorities, providing legitimacy. The absence of detailed privacy and security policies suggests room for compliance improvement. The use of Google Analytics and Tag Manager indicates moderate user tracking for marketing insights. The business appears stable with a clear niche and consistent branding, but limited digital maturity in security and privacy governance.

Security posture

The website demonstrates a basic security posture with HTTPS enforced and cookie consent implemented. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces its defense-in-depth. No explicit incident response or vulnerability disclosure information is provided, which limits transparency and readiness. The WHOIS privacy protection is typical for small businesses but restricts external verification of domain ownership. No vulnerabilities or exposed sensitive data were detected in the analysis. Overall, the security posture is adequate for a small retail site but should be enhanced to meet higher compliance and security standards.

Recommendations

  1. Publish a comprehensive privacy policy page detailing GDPR compliance and data handling practices.
  2. Implement key security headers (CSP, X-Frame-Options, HSTS) to improve site security.
  3. Add explicit incident response and security contact information to enhance transparency.
  4. Regularly review and update third-party scripts and tracking tools to minimize vulnerabilities.
  5. Consider WHOIS data transparency or provide verified domain ownership information to improve trust.

Technical notes

Notes

The website uses a modern tech stack with JavaScript, Google Analytics, Google Tag Manager, and is hosted on Amazon Cloudfront CDN, ensuring good content delivery performance. It is built on the Webnode CMS platform, which provides ease of content management but may limit advanced customization. The site is mobile-optimized and uses responsive design techniques. SEO is supported by proper meta tags and Open Graph data. However, the site lacks advanced accessibility features and security headers. Performance is moderate, with potential improvements in loading speed and accessibility compliance. Overall, the technical infrastructure is solid for a small retail business but could benefit from modernization in security and accessibility.
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.
