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

Bookolo system s.r.o. operates a comprehensive hotel management platform offering a suite of products including booking engine, channel manager, voucher shop, wellness & spa management, online check-in, CRM modules, payment gateway integration, and digital marketing services. The company targets hotels and accommodation providers primarily in the Czech Republic and surrounding regions, positioning itself as a trusted partner to increase direct bookings and optimize hotel operations. The website demonstrates a mature digital presence with rich content, client testimonials, and partner integrations. Technically, the site employs modern JavaScript frameworks, integrates multiple analytics and marketing tools, and enforces HTTPS with reCAPTCHA protections on forms. Privacy and cookie policies are comprehensive and GDPR compliant, with user consent mechanisms in place. However, the absence of WHOIS registration data raises concerns about domain legitimacy, though the business content and contact details strongly indicate a legitimate operation. Security posture is good but could be improved by adding explicit security policies, incident response contacts, and HTTP security headers.

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

3 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.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn

      What to do: Document all third-party data sharing in your privacy policy

  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

Business profile

Bookolo system s.r.o. is a medium-sized company in the hospitality technology sector, offering SaaS solutions that enable hotels to increase direct bookings and reduce dependency on OTAs. Their business model revolves around B2B software and services, including website development, marketing, and branding. The company has a solid client base with notable hotel partners and integrates with payment processors like Global Payments. Their marketing ecosystem includes Google Ads, Sklik, Facebook, LinkedIn, and retargeting services, indicating a strong digital marketing focus. The company emphasizes customer support and continuous product development, as reflected in client testimonials. The partnership with Newlogic Digital for website development and the Bookolo Plus platform for premium content further enhance their market position. Growth indicators include extensive service offerings and a broad partner network.

Security posture

The website demonstrates a good security posture with HTTPS enforced, use of Google reCAPTCHA Enterprise on forms, and cookie consent mechanisms that respect user privacy preferences. Multiple third-party tracking and marketing scripts are used, which increases the attack surface but appear to be managed responsibly. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options is a gap that should be addressed to harden the site against common web attacks. There is no visible security policy or incident response information, which limits transparency and preparedness for security incidents. Publishing a security.txt file and providing explicit security contact channels would improve trust and compliance.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance web security.
  2. Publish a security policy and incident response contact information on the website to improve transparency and readiness.
  3. Create and host a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Verify and update WHOIS domain registration to ensure domain legitimacy and improve trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website uses a modern frontend stack with JavaScript modules, StimulusJS controllers, and smooth scrolling libraries. Fonts are loaded via Adobe Typekit. Analytics and marketing integrations include Google Analytics, Google Tag Manager, Facebook Pixel, LinkedIn Insight Tag, Hotjar, and Browsee, indicating a mature digital marketing infrastructure. The site is mobile optimized with responsive design and accessibility considerations. Performance is moderate, with video backgrounds and multiple external scripts that may impact load times. No CMS or hosting provider information is directly detectable. The site uses Google reCAPTCHA Enterprise for bot protection on forms. Overall, the technical implementation is solid but could benefit from performance optimizations and enhanced security headers.
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.
