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 primarily targeting the Czech market. The company positions itself as a leading Czech provider of photo editing tools, cloud storage, and educational content for photographers and enthusiasts. Their business model includes software sales, subscription services, and supplementary offerings such as photo galleries, printing, and merchandise. The website demonstrates a high level of professionalism with rich multimedia content, tutorials, and customer testimonials, reinforcing their market position. Technically, the website employs modern web technologies including Bootstrap, Google Tag Manager, and asynchronous script loading to optimize performance and user experience. The site is mobile-optimized, accessible, and SEO-friendly, with embedded video content and interactive elements enhancing engagement. Analytics and marketing tools are integrated with user consent mechanisms to comply with privacy regulations. From a security perspective, the site enforces HTTPS and implements a robust cookie consent mechanism with granular user controls. However, it lacks explicit security headers and a published security policy or incident response page. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The absence of WHOIS data from the CZ.NIC server limits domain registration trust assessment, but the website's content and branding suggest legitimacy. Overall, the website presents a secure, privacy-conscious, and user-friendly platform aligned with industry best practices. Strategic recommendations include enhancing security headers, publishing a security policy, and providing explicit incident response contacts 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

6 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. 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

  3. 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

  4. 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

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 editing software market, leveraging a diversified business model that includes software licensing, cloud services, and educational content. Their target customers range from casual home users to professional photographers, schools, and businesses. The company maintains an active digital presence with frequent content updates, tutorials, and customer engagement through social media channels. Their competitive advantage lies in offering an all-in-one solution with intuitive tools, competitive pricing, and localized support. Growth indicators include regular feature updates, awards recognition, and a comprehensive ecosystem of related services. Partnerships with content platforms and marketing networks support their outreach and monetization strategies.

Security posture

The website exhibits a mature security posture with enforced HTTPS and a comprehensive cookie consent framework supporting GDPR compliance. The use of third-party analytics and marketing scripts is managed with user consent, minimizing privacy risks. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No direct contact for security incidents or vulnerability disclosure is provided, which could hinder incident response effectiveness. The lack of a security.txt file or published security policy reduces transparency. Overall, the site is secure for general users but would benefit from enhanced security communication and header implementation.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Create and host a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Provide explicit contact information for security incidents, such as a security@ or abuse@ email address.
  5. Regularly audit and update third-party scripts to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on a modern technology stack featuring HTML5, CSS3, JavaScript, and Bootstrap framework, ensuring responsive design and accessibility. Integration with Google Tag Manager and Helpscout Beacon supports analytics and customer support functionalities. The site loads scripts asynchronously to optimize performance, though some external dependencies could impact load times. No CMS was explicitly detected, suggesting a custom or static site architecture. The site is well-structured with semantic HTML and meta tags supporting SEO. Opportunities exist to improve technical robustness by adding security headers and enhancing hosting 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.
