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

Kolej Jinak is a small hospitality business providing student and group accommodation in Ústí nad Labem, Czech Republic. The company operates seven newly renovated apartments located near the UJEP university campus and city center, targeting students and individuals seeking convenient housing. The business is owned by DREAM PROperty s.r.o., which is disclosed in the website content and EU funding project information. The website is professionally designed with clear navigation, mobile optimization, and relevant content focused on accommodation services. Technically, the website uses a modern but somewhat dated tech stack including jQuery 1.11.1, Slick Carousel, and Magnific Popup, integrated with Google Tag Manager and Google Analytics for marketing and analytics. The site is served over HTTPS with cookie consent mechanisms implemented, indicating good privacy compliance. However, some security best practices such as security headers and incident response information are missing. From a security perspective, the site shows a moderate security posture with no visible vulnerabilities or exposed sensitive data. The absence of WHOIS data for the domain is a concern for domain legitimacy verification, though the website content and business information appear trustworthy. No WAF or blocking mechanisms were detected, and the site is fully accessible. Overall, Kolej Jinak presents a credible and professional online presence for its accommodation services, with room for improvement in security policies and domain registration transparency. Strategic recommendations include enhancing security headers, publishing security and incident response policies, and verifying domain registration details to improve trustworthiness.

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

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

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 · found on this site
  • 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

Kolej Jinak operates in the hospitality sector, focusing on student accommodation near a university in Ústí nad Labem. The business model centers on renting renovated apartments to students and small groups, leveraging proximity to UJEP and city amenities as a competitive advantage. The company benefits from partnerships with local businesses and EU funding for energy efficiency upgrades. The website indicates a small-sized operation with a clear target audience and a localized market position. Revenue streams likely derive from apartment rentals and pre-reservation services. The partnership ecosystem includes event agencies and local venues, enhancing customer experience. Growth indicators include recent renovations and active marketing. Strategic observations suggest focusing on digital marketing, improving security posture, and expanding partnerships to strengthen market presence.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented, supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security posture. There is no publicly available security policy or incident response contact information, which limits transparency and readiness for security incidents. The use of outdated JavaScript libraries (jQuery 1.11.1) may pose potential risks if not regularly updated. Overall, the security culture appears basic but functional, with opportunities to enhance defenses and compliance documentation.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly update all JavaScript libraries and dependencies to their latest secure versions to reduce vulnerability exposure.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Verify and publish domain registration details to improve trust and legitimacy perception.

Technical notes

Notes

The website uses a combination of legacy and modern web technologies, including jQuery 1.11.1, Slick Carousel, and Magnific Popup for UI components, integrated with Google Tag Manager and Google Analytics for tracking and marketing. The site is served over HTTPS with responsive design and mobile optimization. SEO is supported by proper meta tags and Open Graph metadata. However, the absence of a detected CMS suggests a custom or static site architecture. Performance is moderate, with potential improvements by updating libraries and optimizing assets. Accessibility is basic, with room for enhancements. Hosting provider details are not disclosed. Overall, the technical infrastructure supports the business needs but could benefit from modernization and security hardening.
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.
