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

ZONER software, a.s. operates the website www.zoner.cz, offering a comprehensive photo and video editing software suite known as Zoner Studio. Positioned as a leading Czech software provider, the company targets consumers, businesses, and educational institutions with a product that supports advanced editing features, cloud services, and educational content. The website is professionally designed, mobile-optimized, and rich in multimedia content, including tutorials and customer testimonials, reinforcing its market position. Technically, the website employs modern web technologies such as Bootstrap 5, Google Tag Manager, Google Analytics, and Helpscout for customer support. The site demonstrates good SEO and accessibility practices, with a robust cookie consent mechanism ensuring GDPR compliance. However, no explicit security headers were detected, and no dedicated security or incident response pages were found. Security posture is strong with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with detailed policies and user consent controls. The absence of WHOIS data limits domain registration trust analysis, but the website's content quality and external references support its legitimacy. Overall, the site presents a low-risk profile with recommendations to enhance security headers and publish explicit security policies to further strengthen trust and compliance.

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. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • High

      High-Risk Service Exposed: RPC

      Port 135 (RPC) is publicly accessible - RPC - Windows RPC endpoint

      What to do: Consider restricting access to RPC or implementing strong authentication

      • NIS2 21(2)(e)

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

ZONER software, a.s. holds a strong position in the Czech photo and video editing software market, offering a versatile product that appeals to a broad audience including households, businesses, and schools. The business model revolves around software licensing and subscription, supplemented by cloud services, presets, tutorials, and branded educational books. The company leverages partnerships with photography content sites and maintains active social media channels to engage users and promote its offerings. Growth indicators include frequent software updates and a comprehensive content ecosystem supporting user education and engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, secure loading of third-party scripts, and a comprehensive cookie consent framework aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive information were identified. However, the lack of HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options represents an area for improvement. Additionally, the absence of a public security policy or incident response contact limits transparency in security governance. Overall, the site is secure but could benefit from enhanced security best practices and clearer communication channels for security incidents.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Provide explicit contact information for security incidents, such as a security@zoner.cz email address.
  4. Regularly audit and update third-party scripts to minimize risks from external dependencies.
  5. Maintain and communicate clear data retention policies to enhance privacy compliance.

Technical notes

Notes

The website is built on a modern technology stack featuring HTML5, CSS3, JavaScript, and Bootstrap 5 for responsive design. It integrates Google Tag Manager and Google Analytics for tracking and marketing purposes, alongside Helpscout Beacon for customer support chat functionality. The site is mobile-optimized with good accessibility features and SEO metadata. Performance is moderate, with asynchronous loading of scripts to improve user experience. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting provider details were not discernible from the content.
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.
