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.

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.

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

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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Business context
Business profile
The portal represents a large government entity focused on public service delivery, tourism promotion, and regional economic development. Its business model is non-commercial, centered on information dissemination and citizen services. The site integrates with partner domains for tourism, cultural sites, and economic development, indicating a collaborative ecosystem. The multilingual approach and event-driven content suggest a strategy to engage diverse audiences and promote regional activities. The presence of job listings and public tenders also highlights its role in regional governance and employment facilitation.
Security posture
The website demonstrates a solid security foundation with HTTPS and consent-based analytics tracking. The use of a dedicated consent management platform reflects GDPR awareness and compliance. However, the absence of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure information is publicly available, which could enhance transparency and trust. No signs of exposed sensitive data or vulnerable libraries were found, indicating good operational security practices.
Recommendations
Implement and publish explicit security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
Publish a dedicated security policy and incident response contact information to improve transparency and user trust.
Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
Continue monitoring and updating third-party libraries to avoid potential vulnerabilities.
Enhance contact information visibility by including official emails and phone numbers for public inquiries and support.

Technical notes
Notes
The site is built on eZ Platform CMS with React components and modern JavaScript bundles, ensuring a responsive and interactive user experience. The use of Matomo analytics with asynchronous loading and a consent management platform indicates a privacy-conscious approach. Performance is moderate with preloading of fonts and scripts, and mobile optimization is good. Accessibility features such as skip links and ARIA labels are present, supporting inclusive design. SEO is supported by meta tags, canonical links, and structured JSON-LD data. Hosting details are not explicit but domain name servers suggest stable infrastructure.
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.
