Maistra d.d. is a leading Croatian hospitality company specializing in hotels, resorts, and campsites primarily located in Rovinj, Vrsar, Dubrovnik, and Zagreb. The company operates under the Adris Group umbrella and offers a comprehensive portfolio of accommodation and unique experiences targeting tourists seeking premium vacation options in Croatia. The website is professionally designed with multilingual support and a strong focus on user experience and brand consistency. Technically, the site leverages modern frameworks such as Vue.js and Hugo, integrates advanced analytics and marketing tools, and employs secure authentication mechanisms.

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 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Maistra holds a strong market position as a prominent hospitality provider in Croatia, leveraging its parent company Adris Group's resources. The business model focuses on direct bookings through its website, loyalty programs, and curated experiences, targeting leisure travelers and families. The company benefits from a diversified portfolio of brands catering to luxury, select, camping, and urban hotel segments. Growth indicators include new hotel openings and refreshed resorts. Partnerships with technology providers for authentication and marketing enhance operational efficiency. The website's multilingual and multi-currency support indicates a broad international target audience. Strategic observations suggest continued investment in digital marketing and customer engagement to maintain competitive advantage.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, use of Sentry for error monitoring, and secure authentication via Microsoft Authentication Library. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Privacy compliance is supported by comprehensive privacy and cookie policies with consent management. To enhance security maturity, Maistra should publish detailed security policies, establish clear incident response channels, and consider implementing a vulnerability disclosure program.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publicly disclose a vulnerability disclosure program or security.txt file.
  4. Enhance HTTP security headers explicitly (e.g., X-Content-Type-Options, X-Frame-Options).
  5. Maintain transparency in domain registration or consider WHOIS privacy disclosures aligned with business legitimacy.

Technical notes

Notes

The website is built using a modern static site generator (Hugo) combined with Vue.js for dynamic content rendering, ensuring good performance and responsiveness. Integration with cloud services like Cloudinary for media management and Microsoft Authentication for secure login indicates a robust technical infrastructure. Use of advanced analytics and marketing tools such as Google Tag Manager, Bing Ads, Algolia, and Dynamicyield supports data-driven marketing strategies. The site is mobile-optimized with good accessibility and SEO practices. Technical risks are minimal but include reliance on multiple third-party scripts which should be regularly audited for vulnerabilities. Opportunities exist to improve security header implementation and enhance transparency in domain registration.
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.
