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

Croatia Open Umag is an official ATP tennis tournament organized by S.H.O.P. CENTAR d.o.o., established in 2011 and held in Croatia. The website serves as a platform for disseminating tournament news, schedules, player information, and ticket sales, targeting tennis fans and sports enthusiasts. The business operates primarily in the hospitality and sports event sector, maintaining a consistent brand presence and affiliation with the ATP Tour. Technically, the website employs modern web technologies including JavaScript, Google Tag Manager, and New Relic for monitoring, with good mobile optimization and moderate performance. Security posture is strong with HTTPS enforced and cookie consent implemented, though explicit security headers and policies are lacking. Privacy compliance is limited due to missing privacy and terms of service pages. Overall, the site is professional and trustworthy, with room for improvement in compliance and security transparency.

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

2 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 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

  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

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 Croatia Open Umag holds a reputable position as an official ATP Tour event, leveraging partnerships with ATP and an official ticket shop. Its business model revolves around event organization and ticket sales, targeting a niche audience of tennis fans and tourists. The company benefits from a stable domain registration since 2011, indicating operational maturity. Marketing efforts include Google advertising and tracking tools, supporting audience engagement and revenue generation. The absence of detailed contact and compliance information suggests potential areas for operational enhancement. The partnership ecosystem includes ATP and the official ticket shop, reinforcing market credibility.

Security posture

The website demonstrates a solid security foundation with HTTPS encryption and a cookie consent mechanism, reflecting awareness of user privacy and data protection. However, the lack of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which could hinder timely security issue reporting. The use of third-party analytics and advertising scripts introduces potential risk vectors that require ongoing monitoring. Overall, the security posture is good but could be strengthened by formalizing policies and enhancing technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to enhance protection.
  3. Provide clear contact information for security incidents and general inquiries to improve transparency.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate vulnerability risks.
  5. Enhance accessibility features to improve usability for all users and comply with standards.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, JavaScript, and integrates Google Tag Manager and New Relic for analytics and performance monitoring. It loads external resources such as FontAwesome and Google Fonts, contributing to a visually appealing design. Performance is moderate with room for optimization, especially in script loading and resource management. Mobile responsiveness is good, ensuring accessibility across devices. No CMS or hosting provider is explicitly identified. The site lacks some advanced SEO and accessibility features but maintains proper meta tags and language declarations. Technical debt appears low, but improvements in security headers and privacy documentation are recommended.
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.
